Modular PCB Connector With Flexible Board for Easy Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges with compatibility and ease of replacement, as plug-in connectors require one-to-one correspondence with circuit boards and welded connectors are not easily disassembled, leading to increased costs and waste due to the short replacement cycle of electronic components.
Innovation Solution
A connector design featuring a first circuit board with a detachable plug connector to a second circuit board, which is electrically connected to a flexible third circuit board, allowing for easy assembly and disassembly through a plug connector, with features like nickel layers for reliable connections, snap-in portions for secure attachment, and sealing mechanisms to prevent damage and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plug-in connectors are used for connection between circuit boards, then ease of assembly and disassembly is improved, but compatibility between different types of connectors and electronic components deteriorates
Solution Approach 1:
The connector is divided into multiple independent circuit boards (first circuit board, second circuit board, third circuit board) that can be separately assembled and disassembled. This segmentation allows individual boards to be replaced without replacing the entire connector assembly, improving both ease of operation and adaptability.
Solution Approach 2:
The connector design with multiple circuit boards creates a universal interface that can accommodate different electronic components. The standardized plug-in connection structure allows the same connector type to work with various components, enhancing compatibility while maintaining ease of assembly and disassembly.
2Strength
If welded connectors are used for fixed connection, then connection strength is improved, but ease of disassembly and component replacement deteriorates
Solution Approach 1:
The connector transitions from a static welded connection to a dynamic plug-in connection system. The multiple circuit boards can be inserted and removed while maintaining secure electrical connections during operation, providing both strength when connected and ease of replacement when needed.
Solution Approach 2:
The plug-in connector structure acts as an intermediary between the circuit boards, providing a secure mechanical and electrical connection that can be easily engaged and disengaged. This intermediary mechanism achieves both strong connection and ease of replacement without requiring welding.
3Reliability
If entire electrical circuit components are replaced due to single component damage, then reliability is improved, but cost and waste increase
Solution Approach 1:
The electrical circuit is segmented into multiple replaceable circuit boards within the connector. When a single component fails, only the affected circuit board needs to be replaced rather than the entire circuit, maintaining reliability while reducing waste and cost.
Solution Approach 2:
The modular circuit board design enables selective replacement of only the damaged component or board while recovering and reusing the intact circuit boards. This approach maintains system reliability while minimizing material waste and replacement costs.
