Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing flexible printed circuit board (FPC) manufacturing process faces challenges in determining the optimal shape for cutting, leading to material wastage and high production costs due to the intermediate portion being bent and vinyous, making it difficult to arrange FPCs closely and efficiently.
Innovation Solution
A flexible printed circuit board design comprising two components with connectable first and second connection portions, where the first component includes a main body and first signal lines, and the second component includes a connector and second signal lines, allowing for electrical connection via conductive double-side adhesive tape or insertion, enabling efficient alignment and bonding to improve material usage and reduce costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the intermediate portion of the FPC is bent and vimineous to connect the main body and connector, then the FPC can be arranged in three-dimensional space, but it becomes difficult to determine the certain shape for cutting, leading to material wastage
Solution Approach 1:
The FPC is divided into separate components (main body and connector) that can be cut from sheet material in predetermined shapes, then connected through connection portions. This segmentation allows each component to have a certain shape suitable for cutting, improving material usage while maintaining spatial arrangement capabilities through the connection portions.
2Ease of operation
If the intermediate portion is bent and vimineous, then the FPC can connect different components, but the FPCs cannot be arranged closely, resulting in gaps and low production efficiency
Solution Approach 1:
By separating the FPC into components with distinct connection portions, multiple FPCs can be arranged closely in a standardized manner during assembly, improving production efficiency. The connection portions maintain the connection capability while allowing for systematic arrangement.
Solution Approach 2:
The connection portions are designed with standardized structures that can be universally applied to connect different FPC components. This standardization enables efficient automated assembly processes and close arrangement of multiple FPCs, improving both connection capability and production efficiency.
3Adaptability or versatility
If the intermediate portion is bent and vimineous, then the FPC can be flexibly arranged, but it is difficult to determine the certain shape, increasing manufacturing cost
Solution Approach 1:
Dividing the FPC into components with predetermined shapes allows for optimized cutting patterns from sheet material, reducing waste and lowering material costs. Each component can be manufactured using standardized processes, improving ease of manufacture while maintaining arrangement flexibility through the connection portions.
