Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible printed circuits are limited in their adaptability, requiring replacement when connectors change, leading to increased production costs and manufacturing delays due to their specificity in connecting only certain electrical circuits.
Innovation Solution
A flexible printed circuit design featuring a primary body with multiple engaging portions and a secondary body with corresponding engaging and connection portions, allowing for connectivity with various connectors by redesigning only the secondary body to match different joint interfaces, while maintaining consistent specifications across engaging portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flexible printed circuit is designed to connect with specified electrical circuits, then the connection is reliable and stable, but the adaptability to different connectors is poor and replacement is required when connectors change
Solution Approach 1:
The flexible printed circuit is divided into a main body and a separate connection body that can be detached and replaced. The main body contains the circuit patterns, while the connection body interfaces with different connectors. This segmentation allows the connection body to be changed without replacing the entire circuit, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The patent introduces a dynamic configuration where the connection body can be selectively replaced based on connector requirements. The flexible printed circuit transitions from a fixed, static design to one that allows dynamic adaptation of the connection interface while maintaining the stability of the main circuit body.
2Manufacturing precision
If the flexible printed circuit is designed with specific connector interfaces, then the connection precision is high, but the manufacturing complexity increases when multiple connector types are needed
Solution Approach 1:
By separating the circuit into a main body and replaceable connection bodies, each connection body can be optimized for its specific connector interface while sharing the same main body design. This reduces the overall complexity compared to designing multiple complete circuits for different connectors.
Solution Approach 2:
The main body of the flexible printed circuit serves multiple functions by supporting different connection bodies. A single main body design can interface with various connector types through different connection bodies, reducing the need for multiple specialized circuit designs and thereby lowering manufacturing complexity.
3Adaptability or versatility
If the flexible printed circuit is replaced when connectors change, then the connection compatibility is maintained, but the production cost increases
Solution Approach 1:
The flexible printed circuit is segmented into a reusable main body and replaceable connection bodies. When connector compatibility needs to be updated, only the connection body needs to be replaced rather than the entire circuit, significantly reducing production costs while maintaining connector compatibility.
Solution Approach 2:
The design allows for discarding only the obsolete connection body while recovering and reusing the main body of the flexible printed circuit. This selective replacement approach reduces material waste and production costs compared to replacing the entire circuit assembly.
4Adaptability or versatility
If the flexible printed circuit is replaced when connectors change, then the functional adaptability is improved, but the manufacturing time is increased
Solution Approach 1:
The flexible printed circuit is divided into a main body and connection body segments. This segmentation enables independent manufacturing and assembly of connection bodies, allowing for more efficient production workflows where connection bodies can be prepared separately and attached to the main body, improving overall manufacturing efficiency while maintaining functional adaptability.
