Vehicle Lid Support Structure to Prevent Exterior Surface Scratches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lid structures risk scratching the vehicle's aesthetic design surface when the lid is unintentionally opened further, leading to paint peeling and damage.
Innovation Solution
A lid structure featuring a support member with a fixing portion opposite to the opening, a shaft member, and a swingable lid, designed to prevent direct contact between the lid and the exterior surface by applying force orthogonal to the surface, using ribs and a support member contact portion to maintain aesthetic integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the lid is positioned in the vicinity of the design surface when fully open, then the lid structure is compact and simple, but the exterior surface is vulnerable to scratches and paint peeling when the lid is unintentionally opened further
Solution Approach 1:
A buffer member is introduced as an intermediary element between the lid and the exterior surface. This buffer member contacts the exterior surface to apply a buffer force when the lid is unintentionally opened, preventing direct contact between the lid and the design surface, thereby avoiding scratches and paint peeling while maintaining a compact structure
2Object-affected harmful factors
If the lid is positioned away from the design surface when fully open, then the exterior surface is protected from damage, but the aesthetic appearance is compromised and the structure becomes more complex
Solution Approach 1:
The buffer member serves as a hidden intermediary that protects the exterior surface without affecting the aesthetic appearance. When the lid is fully open, the buffer member is positioned to contact the exterior surface only if needed, remaining inconspicuous and maintaining the clean lines and visual continuity of the vehicle's exterior design

AI summary
A lid structure for a vehicle includes a shaft member located on a rear side of an exterior surface that is visible from an outside; a lid that is swingable about the shaft member to open and close an opening formed on the exterior surface; and a support member that rotatably supports the shaft member. The support member includes a fixing portion fixed to the rear side of the exterior surface. When viewed in a direction along the shaft member, the fixing portion is located on a side opposite to the opening with the shaft member as a center.
