Vehicle Door Grip Upward Projection for Interior Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door-equipped vehicle body structures face challenges in supporting the force acting on grips from above without increasing the stiffness of the attachment parts, while also maintaining a wide interior space and preventing interference with luggage or passengers.
Innovation Solution
The door is designed with a grip that projects upward from the upper surface, allowing it to be positioned along the extension line of the general surface, reducing horizontal projection and providing a space between the grip and the vehicle interior, thus supporting the force without increased stiffness and minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the grip projects laterally from the lining toward the inside of the vehicle, then the hand can be placed on the grip from above easily, but the space inside the vehicle is reduced and luggage may interfere with the grip
Solution Approach 1:
The grip is repositioned from a lateral projection toward the vehicle interior to an upward projection from the upper surface of the door. This dimensional change moves the grip into the vertical space above the door, eliminating interference with lateral interior space while maintaining accessibility for hand placement from above.
2Ease of operation
If the grip projects laterally from the lining, then the hand can be placed on the grip from above easily, but the load from above causes a downward rotational force on the attachment part
Solution Approach 1:
The grip is repositioned from a lateral projection toward the vehicle interior to an upward projection from the upper surface of the door. This dimensional change moves the grip into the vertical space above the door, eliminating interference with lateral interior space while maintaining accessibility for hand placement from above.
3Strength
If the grip is positioned to project upward from the upper surface, then the force from above is supported without increased attachment stiffness, but the grip must be precisely positioned along the extension line of the general surface
Solution Approach 1:
The grip is designed with an asymmetric configuration where the longitudinal center line is offset from the vertical center line of the door. This asymmetric positioning along the extension line of the general surface optimizes the structural leverage to support vertical loads without requiring increased attachment stiffness, while the offset configuration facilitates easier installation alignment.

AI summary
A door-equipped vehicle body structure (10) includes a door opening (35) provided to a vehicle (11), a door (40) for opening and closing the door opening (35), and a grip (45) provided to the door (40). The door (40) is provided with a general surface (62) and an upper surface (63). The general surface (62) is a surface extending along a door surface (61). The upper surface (63) is a surface extending from an upper end (62a) of the general surface (62) toward an outside (22) of the vehicle. The grip (45) is provided so as to project upward from the upper surface (63).
