Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in efficiently connecting and supporting circuit boards within rotatable display panels, particularly in rollable display devices, which require reliable electrical connections and structural support during winding and deployment.
Innovation Solution
A display device design incorporating a connector and support component within a housing, with a circuit board exposed out of a rotator, electrically connected to a connector, and protected by protective components, ensuring stable electrical connections and structural support during panel rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector and support component are disposed inside a housing to provide electrical connection and structural support, then reliability of electrical connectivity and structural integrity are improved, but device complexity increases
Solution Approach 1:
The connector and support component are integrated into a single unified structure disposed within the housing. The connector includes connection electrodes for electrical connection while the support component provides structural support, and both functions are achieved through merged design rather than separate components, thus improving reliability while controlling complexity
Solution Approach 2:
The integrated connector-support structure serves multiple functions simultaneously: it provides electrical connection through connection electrodes, structural support for the circuit board, and mechanical stability during rotator operation. This multi-functional design reduces the number of separate components needed while maintaining high reliability
2Reliability
If a first protective component is located between connection electrodes to protect the circuit board, then reliability is improved, but device complexity increases
Solution Approach 1:
The first protective component is integrated between the connection electrodes as part of the connector assembly rather than being a separate standalone component. This protective component shields the circuit board while maintaining electrical connection functionality, achieving protection without adding significant structural complexity
Solution Approach 2:
The first protective component acts as an intermediary element between the connection electrodes and the circuit board, providing protection while allowing electrical connection to occur. This mediator approach ensures reliability through protection without requiring complex additional structures
