Solution Overview
Problem
Conventional slide devices for storage bodies are complex and prone to durability issues due to the increased number of components and intricate structures, particularly with the connection of damper rods, transfer pins, and sliders, which complicates the self-closing and soft-closing mechanisms.
Innovation Solution
A simplified slide device design where the damper rod is directly connected to a slider, allowing the transfer pin to rotate, with an elastic member and a guide passage system that includes a first and second guide passage to facilitate self-closing and soft-closing actions, reducing component complexity and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the end portion of the damper rod is connected to the sub-transfer pin, then the damper can be coupled to the slider, but the number of components increases and the structure becomes complex
Solution Approach 1:
The patent removes the sub-transfer pin from the system and directly connects the damper rod end portion to the slider. This extraction of the unnecessary intermediate component simplifies the structure while maintaining the functional connection between the damper and slider, resolving the contradiction between reliability and structural complexity.
Solution Approach 2:
The patent merges the functions of the sub-transfer pin connection into a direct connection between the damper rod and slider. By combining these elements into a single integrated connection structure, the patent reduces the number of components and simplifies the overall structure while preserving the mechanical linkage function.
2Reliability
If multiple components (damper rod, sub-transfer pin, transfer pin, slider) are coupled together, then the self-closing and soft-closing functions are achieved, but the number of components increases and durability decreases
Solution Approach 1:
The patent extracts and removes the sub-transfer pin component from the system, reducing the total number of components. The direct connection between the damper rod and slider maintains the necessary mechanical function while eliminating the intermediate component that contributed to increased complexity and reduced durability.
Solution Approach 2:
The transfer pin is designed to perform multiple functions: it serves as both the connection point for the damper rod and the engagement mechanism with the slider. This multi-functionality reduces the need for separate dedicated components, thereby reducing the overall number of parts while maintaining system functionality.
3Ease of operation
If the transfer pin is rotatably coupled to the sub-transfer pin and movable along the guide passage, then the self-closing mechanism works, but the structure becomes overly complex
Solution Approach 1:
The patent combines the rotational and translational movement functions into a single integrated transfer pin mechanism. The transfer pin rotates and moves along the guide passage as a unified motion sequence, eliminating the need for separate sub-transfer pin and transfer pin components, thereby simplifying the structure while maintaining the self-closing operation.
Solution Approach 2:
The transfer pin is designed with dynamic movement capabilities, allowing it to rotate and move along the guide passage in response to operational forces. This dynamic design enables the self-closing mechanism to function smoothly without requiring complex fixed structures or additional components to guide the motion.

Function Achieved in This Case
The design simplifies the structure, improves durability, and enhances the self-closing and soft-closing performance by allowing easy coupling and separation of components, while preventing loosening phenomena due to vibration, thereby improving the overall operational efficiency.
Implementation Method 1
an elastic member disposed between and connected to the body and the slider and configured to be elastically compressed or expanded when the slider moves
Implementation Method 2
