Rearview Camera Housing with Integrated Conductive Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rear view device display housings are cumbersome due to multiple components, requiring time-consuming assembly and precise alignment of lighting and reflection means, which is difficult due to manufacturing tolerances.
Innovation Solution
A compact housing design featuring a guide unit directly fixed to the housing body, processed via laser structuring, eliminates the need for a separate circuit board and allows for easier alignment of components, with a conductive section made from polyphthalamide and copper for efficient electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a separate circuit board is used to arrange lighting means and consumers, then electrical connections are established, but the number of components increases and assembly becomes time-consuming
Solution Approach 1:
The patent integrates the circuit board functionality directly into the housing body by creating a conductive section within the housing that serves both structural and electrical connection purposes. This merging of the housing and circuit board functions eliminates the need for a separate circuit board component, thereby reducing the total number of components and simplifying assembly operations.
2Device complexity
If multiple separate components are arranged in the housing, then functional requirements are met, but the housing must be generously dimensioned
Solution Approach 1:
By combining the housing body and circuit board into a single integrated structure where the conductive section of the housing serves dual purposes, the patent reduces the overall housing volume. The integrated design eliminates the need for separate mounting spaces for a distinct circuit board, allowing for a more compact housing configuration while maintaining all necessary electrical and structural functions.
3Ease of manufacture
If lighting means and reflection means are positioned separately, then component mounting is simplified, but exact alignment is difficult due to manufacturing tolerances
Solution Approach 1:
The integration of the lighting means directly into the housing body with the reflection means creates a fixed spatial relationship between these components. This merging eliminates the need for separate mounting operations that would introduce alignment tolerances, as the lighting means is positioned precisely relative to the reflection means through the integrated housing structure itself, ensuring exact alignment while maintaining ease of manufacture.
