Vehicle Door Hinge Installation Kit with Positioning Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing doors on motor vehicles face challenges in maintaining geometrical referencing during separate processing of the body and door, leading to complexity and limited operating range, especially with composite materials and specific hinge types.
Innovation Solution
An installation kit comprising a hinge with a positioning element that allows for the complete removal and subsequent reassembly of the hinge during separate processing of the body and door, without the need for dowel pins or complex tolerance adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the hinge is completely removed from the body during separate processing, then the door can be processed independently, but the geometrical reference is lost
Solution Approach 1:
The hinge is divided into two separate elements: a first hinge element that remains fixed to the door, and a second hinge element that stays fixed to the body. This segmentation allows the door to be completely removed for processing while the first hinge element maintains the geometrical reference on the door, and the second hinge element preserves the reference position on the body.
Solution Approach 2:
The hinge elements act as intermediary components that maintain the geometrical relationship between the door and body even when separated. The first hinge element on the door and the second hinge element on the body serve as reference markers that enable precise reassembly without requiring the hinge to remain physically connected during processing.
2Manufacturing precision
If dowel pins are used to maintain geometrical reference, then the reference is preserved, but the complexity of the working cycle increases
Solution Approach 1:
The geometrical reference function is merged with the hinge elements themselves rather than requiring separate dowel pins. The first and second hinge elements collectively perform both the mechanical connection function and the geometrical reference function, eliminating the need for additional reference components and simplifying the working cycle.
3Productivity
If the pin is slid out of the hinge for separation, then the door can be removed, but the tolerance requirements become excessively stringent
Solution Approach 1:
By segmenting the hinge into two elements that remain on opposite components (door and body), the patent eliminates the need to slide the pin out of a single hinge assembly. This allows for more relaxed tolerances because the reference points are distributed across separate components rather than requiring precise alignment within a compact hinge structure.
4Manufacturing precision
If the hinge remains connected to the body during separation, then the geometrical reference is maintained, but the door cannot be completely removed for processing
Solution Approach 1:
The hinge is segmented into two independent elements that are distributed across the door and body. This allows the door to be completely detached from the body for independent processing while the hinge elements remain in place on各自的 components, preserving the geometrical reference without preventing separation.
