Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in supporting flexible printed circuit boards that are bent within the device, leading to potential damage and instability due to lack of adequate structural support.
Innovation Solution
An electronic device design featuring a frame with a partition wall and a movable support member that applies force to the bending portion of the flexible printed circuit board, allowing it to be positioned either towards or away from the device surface, providing stability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible printed circuit board is bent within the electronic device to connect components, then the device can achieve compact layout and flexible component arrangement, but the bending portion becomes vulnerable to damage and instability due to lack of structural support
Solution Approach 1:
A support member is introduced as an intermediary element between the partition wall and the bending portion of the flexible printed circuit board. This support member provides necessary structural support to the bending portion while maintaining the flexible layout capability, thus resolving the contradiction between adaptability and reliability.
Solution Approach 2:
The support member is designed to be movable relative to the partition wall, allowing it to adjust its position and apply support force dynamically. This dynamic characteristic enables the support structure to adapt to different operational states while maintaining stability of the bending portion.
2Reliability
If a support member is added to provide structural support to the bending portion, then the stability and durability of the flexible printed circuit board are improved, but the device complexity increases
Solution Approach 1:
The support member is designed to perform multiple functions: it provides structural support to the bending portion, acts as a mounting structure for the flexible printed circuit board, and can be movably coupled to the partition wall to accommodate different operational states. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
3Reliability
If the support member is fixed to provide continuous support, then the bending portion is well protected, but the flexible printed circuit board cannot be properly installed or replaced
Solution Approach 1:
The support member is designed with movable coupling to the partition wall, allowing it to be positioned and removed as needed. This dynamic characteristic enables the flexible printed circuit board to be installed and replaced easily while the support member provides protection when required during operation.
Solution Approach 2:
The support member can be pre-positioned or pre-assembled with the partition wall structure, allowing for simplified installation of the flexible printed circuit board. The movable coupling enables preliminary setup of the support structure without permanently fixing it, facilitating ease of manufacture and assembly.
