Rollable Display Rotator Connector Structure for Cable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rollable display devices face challenges in securely connecting and protecting the circuit board within the rotator, leading to issues with electrical connectivity and reliability due to the conductive cable's entanglement and short-circuit defects during rotation.
Innovation Solution
A display device design featuring a connector with connection electrodes and a support component that securely encloses the circuit board, using protective components to prevent short-circuits and ensure reliable electrical connections, while a conductive cable is integrated with the support component to reduce entanglement and enhance mechanical stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the circuit board is exposed out of the rotator for electrical connection, then electrical connectivity is achieved, but the conductive cable becomes entangled and short-circuit defects occur during rotation
Solution Approach 1:
The circuit board is inserted into a cavity formed by the connector and support component, with the connector nested within the housing. This nesting structure protects the circuit board during rotation while maintaining electrical connectivity through the connector's connection electrodes.
Solution Approach 2:
The connector acts as an intermediary component between the circuit board and the external electrical connection. It provides a protected interface that eliminates direct exposure of the cable, preventing entanglement and short-circuit defects while maintaining reliable electrical connectivity.
2Reliability
If the circuit board is securely enclosed and protected, then short-circuit defects are prevented, but the structural complexity increases
Solution Approach 1:
The connector integrates multiple functions: it provides electrical connection through connection electrodes, forms a protective cavity by cooperating with the support component, and eliminates the need for separate protective structures. This merging reduces overall structural complexity while maintaining protection.
Solution Approach 2:
The support component serves multiple purposes: it supports the connector structurally, forms the cavity wall for protection, and provides mounting positions for connection electrodes. This multi-functionality reduces the need for additional components, simplifying the overall structure.
