Molded Blower Housing Connector for Reliable PCB Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for blower control systems in vehicle seats and power battery systems are complex, unreliable, and costly, with separate connectors or wire harnesses that can cause damage and complicate manufacturing.
Innovation Solution
An integrated electrical connector is formed during the molding process of the housing, eliminating the need for separate connectors and simplifying the connection process by embedding pins directly into the housing, which are then electrically connected to the control device, allowing for reliable and cost-effective assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate connector is mounted on the printed circuit board assembly, then the electrical connection is established, but the connector movement may cause damage to the printed circuit board assembly and the structure becomes complex
Solution Approach 1:
The patent integrates the electrical connector directly into the housing structure, merging two previously separate components (housing and connector) into one unified structure. This eliminates the need for separate connectors mounted on the printed circuit board, reducing structural complexity while maintaining connection reliability through the integrated design.
2Reliability
If a wire harness is drawn out of the housing with a plug connector, then electrical connection is achieved, but the arrangement becomes complicated and less reliable
Solution Approach 1:
The electrical connector is integrated into the housing structure, eliminating the need for separate wire harnesses and plug connectors. This merging of components simplifies the wiring arrangement, reduces complexity, and improves reliability by removing potential failure points associated with separate wiring components.
3Ease of manufacture
If a separate connector is used for the control device, then electrical connection is established, but the manufacturing cost increases and manufacturing becomes complicated
Solution Approach 1:
By integrating the electrical connector into the housing, the patent reduces the total number of components that need to be manufactured and assembled. This consolidation simplifies the manufacturing process, reduces assembly steps, and lowers overall manufacturing costs while maintaining full electrical connectivity functionality.
