Vehicle Slide Rail Release Mechanism for Memory Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle slide rail devices face challenges in properly removing the memory member from its default position after the seat position lock is released, leading to potential misalignment during seat position changes.
Innovation Solution
A vehicle slide rail device with a release operation member that includes a first operating body to release the lock mechanism and a second operating body elastically connected to the first, allowing the memory member to be removed from the default position before the lock is released, enabling proper alignment and adjustment of the seat position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lock mechanism is released before the memory member is removed from the default position, then the seat position can be adjusted, but the memory member cannot be properly operated in accordance with the change movement of the seat position
Solution Approach 1:
The release operation member is designed to automatically remove the memory member from the default position before the lock mechanism is released. This preliminary action ensures that the memory member is in the correct state to track seat position changes, preventing the operational failure described in the contradiction.
Solution Approach 2:
The release operation member is divided into a first operating body for releasing the lock mechanism and a second operating body for removing the memory member. This segmentation allows the memory member removal to occur independently and sequentially before lock release, ensuring proper operation of both functions without interference.
2Ease of operation
If the memory member is not removed from the default position before lock release, then the lock can be released, but the memory member misalignment causes improper operation during seat position changes
Solution Approach 1:
The mechanism automatically performs the preliminary action of removing the memory member from the default position before the lock release occurs. This ensures that the memory member is properly aligned and positioned to accurately track subsequent seat position changes, eliminating alignment errors.
Solution Approach 2:
The release operation member is designed to automatically coordinate the removal of the memory member with the lock release sequence without requiring separate manual operations. The mechanism self-regulates the timing and sequence of these actions, ensuring proper alignment through its inherent mechanical design.
3Ease of operation
If the first operating body moves relatively to the second operating body during lock release, then the lock mechanism can be released, but excessive relative movement may overload the mechanism
Solution Approach 1:
An elastic element is introduced between the first and second operating bodies to cushion and absorb excessive relative movement during the lock release process. This elastic element acts as a buffer that protects the mechanism from overload while still allowing the necessary movement for lock release to occur.
Solution Approach 2:
The elastic element changes its mechanical properties (stiffness, deformation) in response to the relative movement between the operating bodies. During normal operation, it allows smooth movement, but when excessive force or displacement occurs, it becomes stiffer to absorb the energy and protect the mechanism from damage.

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 by removing the memory member from a state of defining a default position, wherein a second operating body of the release operation member removes the memory member from the state of defining the default position before a first operating body of the release operation member releases the lock mechanism as the release operation member is operated, and thereafter, the first operating body moves relatively to the second operating body, which is left in a state of removing the memory member from the state of defining the default position, until the first operating body releases the lock mechanism, and wherein an amount of relative movement between the first operating body and the second operating body is elastically absorbed.
