Vehicle Slide Rail Memory Mechanism Offset Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle slide rail devices face issues where the release operation member, when operated from a position offset from the predetermined operation position, cannot properly return to the default seat position due to misalignment with the memory member, leading to ineffective adjustment of the seat position.
Innovation Solution
A vehicle slide rail device with a memory mechanism that includes a memory member with an elastic structure, allowing the release operation member to be received into the predetermined operation position while maintaining the default position, even when operated offset, by tilting and pushing the memory member against its biasing force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the release operation member is operated from a position offset from the predetermined operation position, then the operator can reach the release lever more easily, but the release operation member cannot be properly received into the predetermined operation position, causing the seat position to fail to return to the default position
Solution Approach 1:
The patent introduces an inclined surface as an intermediary element between the release operation member and the memory member. This inclined surface acts as a mediator that guides the release operation member from an offset position back to the predetermined operation position, allowing the operator to reach the release lever more easily while ensuring proper alignment and reliable return to the default seat position.
Solution Approach 2:
The patent employs a curved or inclined surface geometry instead of a flat or linear interface. The inclined surface provides a gradual transition path that naturally guides the release operation member into the correct position, accommodating operational variability while maintaining reliable function.
2Adaptability or versatility
If the release operation member is moved toward the memory member while in the operated state, then the seat position can be adjusted, but the release operation member cannot be received into the predetermined operation position, preventing proper return to default position
Solution Approach 1:
The inclined surface is designed to automatically guide the release operation member back to the predetermined operation position through its geometric shape alone, without requiring additional alignment mechanisms or precise manufacturing tolerances. The structure itself performs the alignment function, making the system self-correcting and more adaptable to operational variations.
3Reliability
If the memory member is pushed and tilted against the biasing force of the elastic structure, then the release operation member can be received into the predetermined operation position, but the elastic structure must be designed to withstand additional forces
Solution Approach 1:
The patent designs the elastic structure to be dynamically responsive, allowing it to flex and tilt when the release operation member is pushed against it. The elastic structure temporarily deforms to accommodate the pushing force, then returns to its original position, providing both reliability in receiving the operation member and managing the strength requirements through controlled deformation rather than rigid resistance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures the seat position can be accurately returned to its default position despite the release operation member being operated from an offset position, enhancing the adjustment mechanism's effectiveness and user convenience.
Implementation Method 1
the receiving structure is configured by an elastic structure by which the memory member is normally biased in a direction intersecting with the slide direction so as to maintain the state of defining the default position, and the memory member is pushed and tilted against the biasing by the movement of the release operation member toward the predetermined operation position

AI summary
A vehicle slide rail device including a release operation member which is configured to release a lock mechanism and slide together with a memory member in a slide direction by removing the memory member from a state of defining a default position; and a memory operation member which is configured to release the lock mechanism and maintain the released state while maintaining the memory member in the state of defining the default position, wherein the memory member has a receiving structure configured by an elastic structure by which the memory member is normally biased so as to maintain the state of defining the default position, and the memory member is pushed and tilted against the biasing by the movement of the release operation member, which is in an operated state, toward a predetermined operation position so that the release operation member is received into the predetermined operation position.
