Constant force spring design for adjustable desk and monitor stand

In order to conform to the height of ergonomics, adjustable desk and display bracket have been widely used in the market. These applications enable people to choose to work sitting or standing, and adjust the appropriate height of equipment to meet the needs of medical care. The application of these two products can not be separated from the constant force spring.
Why is it inseparable? Because the function of lifting in the product is to use the principle of free lifting of constant force spring internally to design a lifter that can adjust the height at will. With the help of the tension of the spring, its height can be adjusted freely.
Constant force springs are characterized by a large output force with little space requirement, applying an almost constant force throughout the stretch. The constant force spring also has the characteristics of short initial preload, that is, it can withstand the rated load at short elongation, and provide long elongation capability. All functions are ideal for use as a balancing function, not only for ergonomic height-adjustable desks and monitor stands, but also for various height-adjustment applications such as patient bedside tables, wall-mounted storage cabinets, monitor and keyboard integrations Medical workstation.
Furniture and Medical Device Design Engineers If you think a constant force spring is a good fit for your application, here are some factors to consider during the design phase of your project.
1. Load conditions
Constant force springs generate force as the material stretches. The rated maximum working length of the constant force spring. This means that the maximum travel must be less than the difference between the unextended length of the spring and the maximum safe working length.
2. Materials
Another important design consideration is materials. Stainless steel 301 is commonly used for standard issue springs. Stainless steel is very resistant to corrosion and damage, making it ideal for applications in the medical field. Most constant force spring selection tables will be based on springs made from 301 stainless steel.
3. Life cycle
You should clearly define the life cycle of the constant force spring to avoid premature failure and also save design costs. The manufacturer’s spring selection table will consider the material (usually stainless steel) as well as the thickness and coil diameter of the spring.
4. Installation method
The installation method will affect the design of your constant force spring. There are several installation methods, so it may depend on your application.
