Solution Overview
Problem
Conventional slide devices for storing bodies have a complex structure and reduced durability due to the increased number of components and coupling of the damper rod, transfer pin, and slider, which complicates the self-closing and soft-closing mechanisms.
Innovation Solution
A simplified slide device design where the damper's rod end is directly connected to a slider with an elastic member, and a transfer pin is rotatably coupled to the slider, allowing for self-closing and soft-closing operations with improved durability by reducing the complexity of the coupling structure and enhancing the binding force of the transfer pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the end of the damper rod is connected to a sub-transfer pin, then the self-closing and soft-closing functions are achieved, but the number of components increases and the structure becomes complex
Solution Approach 1:
The patent combines the sub-transfer pin and transfer pin into a single integrated transfer pin structure. The transfer pin directly couples the damper rod end to the slider, eliminating the need for a separate sub-transfer pin while maintaining the self-closing and soft-closing functions through the elastic member and damper mechanisms.
Solution Approach 2:
The patent removes the sub-transfer pin component from the system entirely. By redesigning the transfer pin to directly receive and transmit forces from the damper rod, the unnecessary intermediate component is extracted, simplifying the overall structure while preserving functional integrity.
2Reliability
If the sub-transfer pin couples the damper rod end, transfer pin, and slider, then the self-closing mechanism operates, but the durability is reduced after numerous opening and closing operations
Solution Approach 1:
The patent merges the sub-transfer pin and transfer pin into a single robust transfer pin that directly couples the damper rod to the slider. This integration eliminates the additional coupling interfaces that would wear over time, reducing the number of potential failure points and improving overall durability while maintaining the self-closing mechanism's operational reliability.
3Reliability
If multiple components are coupled together at the transfer pin, then the soft-closing function is achieved, but the durability of the slide device is reduced
Solution Approach 1:
The patent integrates the sub-transfer pin functionality directly into the transfer pin, creating a unified component that maintains the soft-closing function through the damper and elastic member while reducing the total number of coupling interfaces. This merger minimizes wear points and enhances the overall durability of the slide device.
Solution Approach 2:
The patent extracts and removes the separate sub-transfer pin component, eliminating the additional coupling points that would contribute to wear and reduced durability. The simplified structure maintains soft-closing functionality through fewer, more robust connections.
