Modern people spend more and more time in contact with desks and chairs, and the number of illnesses caused by prolonged sitting or incorrect sitting postures has also increased significantly. Power lift desks allow people to sit and stand alternately to work or study, and have occupied a certain market. The method of online research was used to investigate the size, material, function and other aspects of the currently popular online power lift desks in my country, and the analysis and evaluation were conducted based on ergonomics. Summarize the parameter design and function settings of common power lift desks on the market, and discover the pain points of users. The results show that: the current mainstream market is electric lift desk; power lift desk has more and more functions, and performs well in different aspects of intelligence, safety, comfort, and personalization; Power lift desk has a low penetration rate, cost and selling price Both need to be reduced; supporting services need to be simultaneously improved to better serve people. In the future, power lift desks will develop in the direction of intelligence, personalization, comfort and ease of use, and green and environmental protection.
The most widely used lift function in furniture is the lift chair, which has long been known and used by the public. It is often used in different situations, from hairdressing chairs and bar chairs in streets and alleys to work chairs, study chairs and emerging human body chairs. Engineering chairs are all equipped with a height lifting function. In the 1990s, Power lift desks emerged in developed countries in Europe. They have only entered the Chinese market in recent years. Their development time is short and their popularity is relatively low.
Over the past 10 years, the amount of time spent sitting by young people in our country has shown a clear upward trend, and the passive nature of adult jobs also condemns us to a passive state. Sitting for too long can exceed the body's endurance limit, leading to the irreversible death of cells near the ischial tuberosity, resulting in a number of health hazards. The total time spent working and studying cannot be avoided, but it can break the continuity of a single sedentary behavior. This is where the value of the power lift desk comes into play. It uses the method of alternating sitting and standing to reduce the total time spent sitting throughout the day and to reduce the amount of time spent sitting. In the long run, it will be a great help in reducing the risk of illness. The use of alternating sitting and standing can not only relieve discomfort, but also does not affect the efficiency of work or study, and can improve the energy consumption of the operator. The alternate sitting and standing method is better than the single posture of sitting or standing, and the short cycle alternation The effect could be better. The basic material needs of most people today have been met. On this basis, we will continue to pursue the development of physical and mental health. Relatively healthy ones will gradually replace poor office and study conditions. China's electric lift desk consumer market has huge development potential.
1. Power Lift Desk Survey Content and Methods
This survey mainly uses the online research method, selecting 10 lift desks as survey objects, obtaining specific information from the website, analysing it based on field experience and online reviews, and surveying people's familiarity with lift desks and chairs through an online questionnaire. and evaluation. The purpose of this survey is to study the ergonomic characteristics of lift desks and chairs, analyse the current market situation, discover further requirements for lift desks and predict the future development of lift desks.
2. Power Lift Desk Research and Analysis
2.1 Classification of Power Lift Desk Lifting Methods
Power lift desk lifting methods are divided into mechanical lifting and electric lifting. At present, the main mechanical lifts on the market are hand crank and pneumatic; electric lifts are divided into single motor and dual motor. There are also desk lift workstations.
Mechanical Lifting Type: Hand Crank Type
When lift desks first came on the market, most used manual lifting. Mechanical lifting was achieved by manually rocking the rocker. The price was relatively low. However, it was difficult to use because of the need to adjust posture to coordinate movements during use, and the lifting speed was slow and uncomfortable.
Mechanical Lifting Type: Pneumatic Type
Pneumatic type is also a commonly used adjustment method for lift desks, but due to its poor stability in height adjustment, it is less and less used in lift desks and more commonly used in smaller table lift workbenches or small lift desks
Electric Lift: Single Motor and Dual Motor
Motorized lift has been the mainstream product in the market in recent years. Compared with the large movements of the hand crank type, the motor lift mainly adjusts the height by pressing the operation button or clicking commands on the touch screen. The movement is smooth and fast. The LED screen displays the height in real time. With its intelligent advantages, the motorized lift table can develop many other additional functions.
2.2 Power Lift Desk Size Analysis
In order to understand consumers' feelings and needs for power lift desks, 10 lift desks were selected and analyzed in terms of size, material, and function, and their ergonomic factors were evaluated.
2.2.1 Lift Desk Height
The height adjustment function of the power lift desk allows the height of the desk to be changed within a certain range: First, the height of the desk can be adjusted to match the scale of the seat so that the difference is within the appropriate range, reducing the misalignment caused by mismatched table and chair heights. Secondly, users can alternate sitting and standing to perform work, relieving the pressure on the lower body, reducing fatigue and improving work efficiency. The height of the desktop should be based on improving work efficiency and reducing fatigue. If the desktop is too high or too low, it will have a bad effect on people. Research shows that the optimal desktop height is closely related to a person's elbow height. Since different people have different elbow heights, a electric lift desk that can adjust the height of the desktop is very necessary.
When used as a sitting desk, the appropriate desk height is 690 ~ 780 mm. If the minimum desktop height of the power lift desk is too high and restrictive for children, an additional step platform is required to ensure a comfortable sitting posture. When the power lift desk is used as a desk, the horizontal workspace remains the same, but the vertical workspace changes. People often read and perform other tasks while standing. Human comfort is best when the desk is slightly higher than human elbow height. These 10 lifts The desk is within the appropriate range when used as a desk.
2.2.2 Lift Desk Desktop Width
The width of the desktop is determined based on the range of human hand activity, the field of view of the human eye, and the items placed on the desktop. In general, the width of the desktop is based on the lateral extension of the human arm, and the depth of the desktop is based on the forward extension of the human arm. Based on the normal range of arm movement, the width of the desk should be at least 400 mm. Because other items need to be placed, it is actually larger than 400 mm. If items such as computers and keyboards are to be placed, the width of the desk must be more than 600 mm.
2.3 Lift Desk Material
Material is the material base and also determines the appearance and texture. With the development, the kinds of furniture materials are becoming more and more abundant, but wooden materials are still the first choice. Electric lift desk is quasi-human body furniture, which is in direct contact with the human body. Tactile comfort is very important. The materials of the 10 lift tables are as follows:
Desk top material: artificial board (density board, fiber board, particle board, wood chip board), metal (iron sheet, cold-rolled sheet), metal, composite board, tempered glass, plastic
Desk frame material: metal (iron sheet, cold-rolled steel, high-strength aluminum)
Most of the desktop materials are artificial panels. The thermal conductivity of wood is small, it has a good sense of cold and heat, good humidity control performance, and good tactile comfort when used. There are also 2 models that use metal and tempered glass as the desktop. The thermal conductivity of metal and glass is large, the tactile characteristics are cold, and the humidity control performance is poor, which cannot form a good microenvironment at the human-desk interface, and the tactile comfort is slightly worse. But it is scratch-resistant, pressure-resistant, high-temperature-resistant, and durable, giving people a refined and modern feel.
The desk frame is entirely made of metal, which is strong and durable, has high strength and heavy weight, and the parts are easy to assemble.
2.4 Electric Lift Desk Function
After meeting the basic functions of height adjustment, the lifting table adds a series of humanized functions to increase product competitiveness and meet the needs of consumers in different aspects. It is analyzed from the four aspects of intelligence, safety, comfort and personalization.
2.4.1 Intelligence
At present, electric lift desks are equipped with a height memory function and real-time LED screen, which can set multiple heights and enable touch interaction between fingers and the screen. Some also support voice control, allowing for linkage of equipment throughout the house. In addition, the intelligent lifting desk has changed from passive to active. The height of the lifting desk can be controlled regularly through the mobile APP software. It also has health management, statistical data and other functions. The operator may forget to change postures when concentrating for a long time. The intelligent lifting desk determines the operator's status based on the data and provides health reminders.
2.4.2 Security
Many lifting desks have rebound protection when encountering obstacles. When encountering obstacles during the lifting process, they will stop immediately or rebound a certain distance before automatically stopping; many electric lifting desks are equipped with safety locks or child locks to increase safety; some lifting desks The table has reserved space for hand operation on the edge of the table to avoid the hidden danger of pinching hands when raising or lowering the tabletop.
2.4.3 Comfort
Among the 5 desk converters, 4 are equipped with keyboard trays, allowing you to have a good experience while standing while typing; 3 desktops have concave tabletop designs to better fit the curves of the body and elbows when using them while standing. The support is more stable. There is also an electric desktop converter with a built-in wireless charging module that can quickly charge mobile phones at 10 W and can automatically power off without consuming any power. Some power lift desks are equipped with plug strips and USB holes on the table to facilitate the connection of electronic products on the table, which can effectively reduce the problem of confusing cables on the table or under the table. In addition, when changing the height, the operation of the lifting table is very simple and clear. It can be easily achieved through different upper and lower buttons or foot pedals. It is simple and easy to operate and gives people a comfortable experience.
2.4.4 Personalization
Electric lift desks allow you to match the material and color of the tabletop and table legs. However, most of the lift desks have no choice and have fixed shapes and functions, which cannot meet individual needs for the time being.
3. Analysis of survey results
3.1 Questionnaire Survey Analysis
A questionnaire survey was conducted online. Most of the respondents were students and employees engaged in general work. People who use power lift desks are more sensitive to health issues caused by occupational sitting postures. The questionnaire found that more than half of the people were unfamiliar with lift desks and were in a Only aware of its existence but not understanding it, less than 1/4 of the people have used it, and 1/4 of the people have no idea about the power lift desk at all. After a preliminary understanding of the Standing Desk, 85% of people believed that the standing lift desk can bring substantial benefits to people, and about 70% of people were willing to buy it.
Questionnaire surveys show that people have different concerns about the use of height-adjustable tables. The most common view is that the frequency of changes in daily use is low and it becomes an ordinary table, losing the original intention of buying a electric lift desk. The second is that it is used in public places such as offices. It is difficult to use it in some situations. The height-adjustable lift desk is currently only popular in a few large enterprises, and the penetration rate is low. Therefore, when using it in the office, some people worry that it will be different from others, causing unnecessary trouble.
3.2 Buyer Demand Analysis
Based on a comprehensive analysis of the buyer feedback and on-site experience communication, consumers are dissatisfied or factors that lead to hesitation when purchasing. One is the product itself, and the other important factor is the supporting services.
3.2.1 The Product Itself
As for product quality, many consumers find quality problems when actually using them after purchasing. There are unstable phenomena. The desk shakes when typing, and the bottom surface of the lifting table cannot fit the desktop, which also causes shaking, greatly reducing the user experience. There are also phenomena of poor quality accessories, such as screws and bolts that are inconsistent with the table, and the type There are deviations in the hole positions; some lift desks have rough details, have protruding particles that have not been polished smoothly, the corners are not rounded, and the tabletop plates have defects, etc. As for the function of a electric lift desk, height adjustment alone cannot meet the needs of consumers, not to mention that a certain amount of storage space and viewing ability need to be sacrificed. Power lift desk need to have more selling points to attract consumers. The design of more intelligent electric lift desk is a direction worthy of attention in the future.
3.2.2 Supporting services
The installation of lift desks is troublesome. A heavier table requires at least two people. Some merchants will provide door-to-door installation services, but those without corresponding services can only install it by themselves, which is laborious and tiring. When purchasing power lift desks through online platforms, many merchants do not have free shipping insurance for returns and exchanges means that you have to pay high courier fees if you want to return the goods. Moreover, the price of the online electric lift desk fluctuates greatly. The merchant does not insure the price and cannot save money by returning the product and repurchasing it. After the warranty period of the lifting table has expired, it is relatively difficult to repair if there is a problem trouble.
