Flexible Display Circuit Board Holder for Rolling Stress Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices require an effective mechanism to accommodate their driving components, such as flexible circuit boards and printed circuit boards, while allowing for easy rolling and unrolling, which is not adequately addressed by existing technologies.
Innovation Solution
A display device design that includes a handle with a roller and holders to securely position and accommodate the flexible circuit board and printed circuit board, ensuring they are not damaged during rolling and unrolling, with a connection part to securely attach the printed circuit board to the holder, preventing separation and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible display devices are designed to be rolled and unrolled, then portability and user convenience are improved, but the driving components (circuit boards) are subjected to mechanical stress that can cause separation or damage
Solution Approach 1:
The circuit boards are nested within the holder structure, which provides a protective cavity that accommodates the driving components during rolling and unrolling operations. This nesting arrangement ensures components remain contained and protected while enabling the flexible display to be rolled.
Solution Approach 2:
The holder is pre-configured with positioning structures and connection parts that secure the circuit boards before rolling occurs. This preliminary arrangement of components within the holder prevents separation and damage during the subsequent mechanical stress of rolling and unrolling.
2Reliability
If circuit boards are securely attached to prevent separation, then component reliability is improved, but the device structure becomes more complex
Solution Approach 1:
The holder integrates multiple functions into a single structure: it provides accommodation space for circuit boards, includes positioning structures for secure attachment, and offers protection during rolling. This merging of functions reduces the need for separate components and simplifies the overall device structure.
Solution Approach 2:
The holder is designed as a multi-functional component that simultaneously serves as a protective enclosure, a mounting structure with positioning features, and a structural element that maintains component integrity during flexible deformation. This multi-functionality eliminates the need for additional separate structures.
