Slide Assembly Elastic Force Adjustment for Consistent Drawer Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push-open type slide structures fail to adjust elastic force effectively, leading to inconsistent drawer opening positions when handling different loads, causing confusion and improper access to objects.
Innovation Solution
An elastic force adjustment device with a fixing member, movable member, adjustment frame, and elastic members, allowing for adjustable stored elastic force by rotating an adjustment member on a threaded rod, enabling precise control of rail travel distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed elastic force device is used in the push-open type slide structure, then the structure is simple and easy to manufacture, but the drawer cannot open to the desired position when handling different loads
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed elastic force device into an adjustable one. The adjustment member can rotate along the threaded rod to change the pre-compression amount of the elastic member, allowing the elastic force to be dynamically adjusted according to different load conditions. This enables the slide structure to adapt to various drawer weights while maintaining a relatively simple device structure.
Solution Approach 2:
The patent implements parameter changes by modifying the pre-compression amount of the elastic member through the adjustment member. By rotating the adjustment member along the threaded rod, the position of the adjustment frame changes, thereby altering the pre-compression amount and the corresponding elastic force. This allows the system to adapt to different load requirements by changing the elastic force parameter.
2Force
If the elastic force is increased to handle heavy loads, then heavy drawers can be opened, but light drawers may open too far or with excessive force
Solution Approach 1:
The patent uses parameter changes to adjust the elastic force according to different drawer weights. By rotating the adjustment member to different positions on the threaded rod, the pre-compression amount of the elastic member is changed, thereby adjusting the elastic force. This allows the user to match the elastic force to the actual load, ensuring that both light and heavy drawers can open to the desired position without excessive force or insufficient opening.
3Adaptability or versatility
If multiple drawers with different loads are installed, then the furniture can accommodate various items, but the drawers open to different positions causing user confusion
Solution Approach 1:
The patent applies parameter changes by allowing each drawer's slide structure to have its own adjustable elastic force setting. Users can rotate the adjustment member on each drawer to set the appropriate pre-compression amount according to the drawer's load weight. This ensures that all drawers, regardless of their load differences, can open to consistent and desired positions, eliminating user confusion while maintaining the ability to accommodate various items.
