Lid Latch Pressing Mechanism to Prevent Vehicle Body Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lid opening and closing devices allow the lid to rise up from the vehicle body due to gaps between the lid latching parts, compromising appearance and creating security vulnerabilities.
Innovation Solution
A forward/backward movement device with a biasing member, engagement parts, and a pressing force transmitting member that ensures the lid is securely locked in the closed position by engaging and disengaging mechanisms to prevent upward movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid is closed using the latching mechanism, then the lid is secured in the closed position, but gaps between the lid latching part and the lid to-be-latched part cause the lid to rise up from the vehicle body
Solution Approach 1:
A pressing force transmitting member is introduced as an intermediary component between the lid and the vehicle body. This member transmits pressing force from the vehicle body to the lid, ensuring the lid remains firmly pressed against the vehicle body without direct contact between the latching parts causing the gap issue. The intermediary member eliminates the harmful effect of gaps while maintaining the closure security function.
2Ease of operation
If the pressing force transmitting member is biased in the protrusion direction, then the lid can be pushed open, but the lid pushes back against the vehicle body creating a visible gap
Solution Approach 1:
The harmful protrusion of the pressing force transmitting member is extracted or repositioned so that it does not extend beyond the outer surface of the vehicle body. By taking out the protruding portion that causes the visible gap, the lid can still be pushed open through the mechanism, but the aesthetic appearance is maintained as the pressing force transmitting member no longer creates an unsightly protrusion.
3Adaptability or versatility
If gaps are present between the lid and vehicle body, then the lid can move freely, but tools or other objects can be inserted through the gap creating security issues
Solution Approach 1:
The pressing force transmitting member provides beforehand cushioning or pre-compression between the lid and the vehicle body. By maintaining continuous pressing force even when the lid is closed, the member prevents gaps from forming in the first place. This prior cushioning effect ensures that no insertion space is created, thereby preventing crime while maintaining the necessary lid movement flexibility for normal operation.

AI summary
In a forward/backward movement device, when a forward/backward movement member moves forward, an engagement part and a to-be-engaged part are in an engaged state such that a biasing force of a biasing member is applied to a pressing force transmitting member, and when the pressing force transmitting member is positioned in a backward position, the engagement part and the to-be-engaged part are in a non-engaged state such that the biasing force of the biasing member is not applied to the pressing force transmitting member.
