Driver Monitoring Camera Bridge Assembly for PCB Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver monitoring systems face challenges in assembly complexity due to wire connections between printed circuit boards and require numerous parts, making automatic assembly difficult.
Innovation Solution
A vision camera design with integrated electrical connectors in a bridge that allows for automatic assembly by eliminating screw connections and reducing the number of parts, featuring a housing with embedded and overmolded connectors that establish electrical contact during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire connections and screw connections are used between printed circuit boards, then reliable electrical connections are established, but assembly complexity increases and automatic assembly becomes difficult
Solution Approach 1:
The patent combines multiple separate components (printed circuit boards, wire connections, and screw connections) into a single integrated housing structure. The housing itself serves as the mechanical support structure and simultaneously provides integrated electrical connectors, eliminating the need for separate wire connections and screw fastenings between multiple PCBs.
Solution Approach 2:
The housing is designed to perform multiple functions simultaneously: it provides mechanical support, houses the optical components, and integrates the electrical connection system. The electrical connectors are built into the housing structure, allowing the housing to serve both as a structural element and as an electrical interconnection system.
2Reliability
If multiple separate printed circuit boards with connectors are used, then electrical connections can be established, but the total number of parts increases
Solution Approach 1:
The patent merges multiple separate printed circuit boards into a single integrated housing structure. Instead of having separate PCBs with individual connectors, the housing itself is designed as a single piece that incorporates all necessary electrical connection points and structural support, thereby reducing the total part count.
Solution Approach 2:
The housing structure is designed to perform multiple functions that were previously distributed across multiple components: mechanical support, electrical connection, and component mounting. This multi-functional design eliminates the need for separate connectors and fasteners, reducing the overall number of parts required.
