Vehicle Door Hinge Support Elastic Deformation Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hinge support for vehicle doors experiences difficulties in assembly due to elastic deformation of the hinge counter-holder during screw tightening, leading to potential misalignment and time-consuming repositioning, making the process cumbersome and inefficient.
Innovation Solution
The hinge counter-holder is limited to small adjustment movements by wall areas or stops on the stiffening part, with an access opening that can be manually or mechanically enlarged for easy insertion, allowing for immediate screw alignment and secure fastening, enabling quick and reliable assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hinge counter-holder is held loosely in the receiving space to allow adjustment movements, then the hinge counter-holder can be positioned during assembly, but it may end up in an unfavorable tilted position requiring time-consuming repositioning
Solution Approach 1:
The hinge counter-holder is pre-positioned in the receiving space during assembly before final tightening of the threaded screw. The design allows the hinge counter-holder to be inserted and preliminarily positioned, where it can perform only small adjustment movements limited by wall areas and stops, ensuring it settles in the correct position without requiring subsequent repositioning operations.
2Manufacturing precision
If the hinge counter-holder is tightly fixed during assembly to prevent movement, then alignment is maintained, but the hinge counter-holder cannot be easily inserted into the receiving space
Solution Approach 1:
The receiving space is designed with elastically deformable wall areas that transition from a deformable state during insertion to a rigid state during operation. During assembly, the elastically deformable wall areas allow the hinge counter-holder to be inserted with movement freedom. After insertion, these same wall areas provide rigid constraints that maintain precise alignment when the threaded screw is tightened.
Solution Approach 2:
The physical state of the receiving space walls changes during the assembly process. The wall areas are designed to be elastically deformable under insertion forces, allowing the hinge counter-holder to be positioned. Once positioned, the elastic deformation recovers or is constrained, transforming the wall areas into rigid boundaries that maintain alignment precision during final fastening.
3Adaptability or versatility
If the hinge counter-holder is allowed to perform large adjustment movements, then it can reach the correct position, but it may require time-consuming repositioning if it ends up in an unfavorable position
Solution Approach 1:
The hinge counter-holder is pre-positioned within constrained movement boundaries during assembly. The wall areas and stops are designed to guide the hinge counter-holder into the correct position during insertion, performing the alignment action preliminarily before final fastening, thereby eliminating the need for subsequent repositioning operations.
4Strength
If the access opening is kept small for structural integrity, then the stiffening part maintains strength, but the hinge counter-holder cannot be easily inserted
Solution Approach 1:
The access opening is formed by elastically deformable wall areas that temporarily yield during insertion to accommodate the hinge counter-holder, then recover to maintain structural integrity. The wall areas are designed with elastic properties that allow controlled deformation during assembly operations while preserving the overall structural strength of the stiffening part during normal operation.

Function Achieved in This Case
This solution facilitates a straightforward and cost-effective assembly process by ensuring the hinge counter-holder is always in a correct position for screw insertion, allowing for easy installation and secure attachment to the stiffening part, enhancing the assembly efficiency and reducing manual effort.

AI summary
The hinge support has a thread screw (7) and a wall area (14,15,16,17) or an inset (18), where the adjustable movement of the thread screw and the wall area or the inset is limited at stiffening part (9). A retaining area (11) is provided with an access opening (12), by which a hinge brace (10) is inserted and removed in or from the retaining area if the wall area of the stiffening part is elastically deformed manually or machinery.
