Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hooking devices for drawers on pull-out guides face issues with imprecise lateral alignment due to dimensional tolerances and play, leading to potential jamming, breakage, and instability, especially during maximum extension and lateral adjustment.
Innovation Solution
A device with elastically yieldable coupling parts that engage forcibly and shape-wise to compensate for lateral play between the hooking device and the pull-out guide, ensuring precise positioning and stable coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional rigid coupling parts are used between the hooking device and pull-out guide, then the structure is simple, but lateral play causes imprecise positioning and unstable engagement
Solution Approach 1:
The coupling parts are designed with elastically yieldable means that change their physical state from rigid to flexible under lateral load, allowing them to deform elastically and compensate for dimensional tolerances and lateral play, thereby achieving precise positioning without increasing structural complexity
Solution Approach 2:
The elastic yieldable means act as a pre-designed cushioning mechanism that absorbs lateral play and dimensional variations before they can cause positioning errors or engagement instability, ensuring reliable coupling under varying conditions
2Reliability
If conventional rigid centring elements are used, then the device is constructionally simple, but lateral play causes jamming or breakage during hooking-up
Solution Approach 1:
The centring elements are made elastically yieldable, allowing them to dynamically adjust their dimensions under lateral stress during the hooking-up process, preventing jamming and breakage while maintaining structural simplicity
Solution Approach 2:
The elastic properties of the centring elements provide advance protection against lateral misalignment and interaxis differences, cushioning the impact during assembly and preventing damage without requiring complex alignment mechanisms
3Measurement precision
If conventional rigid coupling parts are used, then the structure is simple, but lateral play reduces the effectiveness of lateral adjustment
Solution Approach 1:
The elastically yieldable coupling parts dynamically adjust their physical parameters under lateral load, eliminating lateral play and enabling precise lateral adjustment of the drawer position without requiring complex adjustment mechanisms
