Constant-Force Spring Support for Height Adjustment and Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitor support devices are costly due to the high price of air pressure bars used for height adjustment and occupy significant space when not in use, as the work platform is fixed and non-rotatable.
Innovation Solution
A support device utilizing two constant force springs, one for the monitor mount and one for the work platform, allowing for adjustable height and easy folding, replacing the need for air pressure bars and enabling space-saving storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If air pressure bars are used for height adjustment, then height adjustment accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces expensive air pressure bars with constant force springs that are simpler, more durable, and significantly cheaper to manufacture. The constant force springs provide sufficient height adjustment functionality without requiring complex pneumatic systems, thereby reducing manufacturing costs while maintaining acceptable adjustment precision.
Solution Approach 2:
The patent substitutes the pneumatic system (air pressure bar) with a purely mechanical system (constant force spring). This replacement eliminates the need for compressed air generation and control mechanisms, simplifying the overall system and reducing manufacturing complexity and cost.
2Stability of the object's composition
If work platform is fixed and non-rotatable, then structural stability is improved, but space occupation increases
Solution Approach 1:
The patent transforms the work platform from a fixed, static structure to a dynamic, rotatable structure. The platform can now rotate between a horizontal working position and a vertical storage position, allowing it to adapt its configuration based on usage requirements. This dynamic capability enables space-saving storage while maintaining structural stability during actual use through proper locking mechanisms.
Solution Approach 2:
The patent utilizes the vertical dimension for storage by allowing the work platform to rotate into a vertical position, effectively using the third dimension (height) to reduce the footprint in the horizontal plane. This dimensional transition enables the same platform to serve both as a large horizontal workspace and a compact vertical storage element.

AI summary
A support device includes an upright frame and upper and lower constant force springs. The upright frame includes upper and lower members respectively defining upper and lower receiving spaces, and an upright frame body between the upper and lower members and having two first slide grooves communicating with the upper receiving space and two second slide grooves communicating with the lower receiving space. Each of the upper and lower constant force springs includes a coiled portion disposed in a respective one of the upper and lower receiving spaces, and a free end connected to the coiled portion. First and second slide units are slidably mounted on the upright frame body.
