Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible display apparatuses face challenges in efficiently expanding display area and improving portability while maintaining secure connection and preventing disconnection between the display part and the circuit sheet during rolling and unfolding operations.
Innovation Solution
A display apparatus design featuring a flexible display part, a housing with a revolving part, a fixing part, and a pressing part, where the display part is wound on a cylindrical roll with spiraling rails and held by elastic members, ensuring secure engagement and preventing disconnection by using a seesaw mechanism and a lockup member to maintain the display in a spread state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display part is made flexible and wound on a revolving part, then portability and display area expansion are improved, but the risk of disconnection between the display part and circuit sheet increases
Solution Approach 1:
The connection structure is divided into multiple functional segments: the circuit sheet with connection protrusions, the reinforcing structure with corresponding connection recesses, and the locking mechanism. This segmentation allows each component to perform its specific function while maintaining overall connection reliability during rolling operations.
Solution Approach 2:
The connection protrusions and recesses are pre-formed on the circuit sheet and reinforcing structure before assembly. This preliminary preparation ensures that when the display part is rolled onto the revolving part, the connection elements are already positioned to engage properly, preventing disconnection during the rolling process.
2Area of moving object
If the display part is wound on a revolving part, then display area expansion is improved, but the connection between display part and circuit sheet may become disconnected
Solution Approach 1:
The circuit sheet is nested within the reinforcing structure, with the connection protrusions fitting into the connection recesses. This nested arrangement ensures that the circuit sheet remains securely positioned within the reinforcing structure during rolling and unfolding, maintaining connection stability while enabling display area expansion.
Solution Approach 2:
The locking mechanism acts as an intermediary element between the connection protrusions and recesses. It engages with both components to secure their relative positions, preventing disconnection while allowing the display part to be wound on the revolving part for expanded display area.
3Reliability
If a fixing part is used to secure the display part, then connection stability is improved, but the structure becomes more complex
Solution Approach 1:
The locking mechanism is merged with the existing connection structure between the circuit sheet and reinforcing structure. Rather than adding a separate fixing part, the locking elements are integrated into the connection protrusions and recesses, maintaining connection stability while minimizing structural complexity.
Solution Approach 2:
The connection protrusions and recesses serve multiple functions: they provide mechanical connection between the circuit sheet and reinforcing structure, and simultaneously act as locking elements to prevent disconnection during rolling. This multi-functionality eliminates the need for separate fixing parts, reducing structural complexity.
