FPCB Support Structure Preventing Connector Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with flexible printed circuit boards (FPCBs) are prone to separation from connectors due to shocks, leading to connectivity issues and reduced durability.
Innovation Solution
Incorporating a reinforcement member and support structure with adhesive members to secure the FPCB between the printed circuit board and the connector, preventing separation and enhancing maintainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible printed circuit board is used to connect components, then flexibility and ease of installation are improved, but reliability deteriorates due to separation from connectors under shock
Solution Approach 1:
The support member is pre-installed between the FPCB and connector before assembly, creating a preliminary protective structure that prevents separation under shock while maintaining the FPCB's flexibility and ease of installation
Solution Approach 2:
The support member acts as an intermediary element between the FPCB and connector, providing mechanical reinforcement that prevents direct separation while allowing the FPCB to maintain its flexible characteristics
2Reliability
If the FPCB is secured with additional support members and adhesive members, then reliability is improved by preventing separation, but device complexity increases
Solution Approach 1:
The support structure is segmented into distinct components (support member, first adhesive member, second adhesive member) that can be independently manufactured and assembled, making the complex structure manageable and manufacturable
Solution Approach 2:
The support member combines multiple functions into a single component: it provides mechanical reinforcement, positioning alignment, and shock absorption, while working with adhesive members to create an integrated support system
3Duration of action of stationary object
If the FPCB is reinforced to prevent separation, then durability is improved, but manufacturing complexity increases
Solution Approach 1:
The support member is pre-installed during the manufacturing process before final assembly, allowing for quality control inspection and ensuring proper positioning before the FPCB is permanently secured to the connector
Solution Approach 2:
The manufacturing process is segmented into distinct steps: installing the support member, applying adhesive members, and securing the FPCB to the connector, making the manufacturing process more manageable and controllable
