Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle slide rail devices have complex detection structures that interfere with other operation systems, making it difficult to efficiently return a seat to a locked state without unnecessary complexity.
Innovation Solution
A vehicle slide rail device with a simplified detection structure, featuring a memory operation link, holding link, detection member, and variable structure that allows the seat position to return to a default position by mechanical engagement, avoiding interference with other systems through a controlled movement of the pressing portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a detection structure is brought into contact with the memory member to return the seat to a locked state, then the seat can be returned to the default position, but the detection structure becomes complicated and large in configuration to avoid interference with other operation systems
Solution Approach 1:
The detection member is integrated into the existing memory operation link mechanism. The detection member utilizes the movement of the memory operation link itself to detect the seat position and trigger the return to locked state, eliminating the need for a separate complex detection structure. This merging of detection function into the operational mechanism resolves the contradiction by maintaining reliability while reducing device complexity.
Solution Approach 2:
The memory operation link serves multiple functions: it operates the memory mechanism to define default position, and simultaneously serves as the detection structure to detect seat position and trigger the return to locked state. This multi-functionality eliminates the need for separate detection components, reducing overall system complexity while maintaining the required reliability for seat position detection and return function.
2Adaptability or versatility
If a separate detection structure is used to avoid interference with other operation systems, then interference is avoided, but the detection structure becomes large and complicated
Solution Approach 1:
The detection function is merged into the memory operation link, which is already an integral part of the seat adjustment system. This integration allows the detection mechanism to operate within the existing system architecture without requiring separate components that could interfere with other operations, while simultaneously reducing the overall complexity and size of the detection structure.
Solution Approach 2:
The memory operation link detects the seat position and triggers the return to locked state using its own movement and position information. The system uses itself for detection purposes, eliminating the need for external or separate detection structures that would add complexity and potential interference with other operation systems.

Implementation Method 1
a holding link which is configured to, in response to an operation of the memory operation link, be engaged with the memory operation link by being biased and hold the memory operation link in a release operated position
Implementation Method 2
press a pressing portion of the holding link by being brought into contact with a trigger member installed at a predetermined slide position
