Optical Fingerprint Sensor Elastic Support for Reusable Module Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fingerprint sensor apparatuses face performance limitations due to the low reuse rate of components, as the optical fingerprint sensor module is often damaged during removal from the self-luminous display panel, leading to inefficient repair and replacement.
Innovation Solution
The optical fingerprint sensor apparatus incorporates a support frame structure with an opening, an optical fingerprint sensor module, a support plate, an elastic support member, and a self-luminous display panel, where the elastic support member is fixedly connected between the sensor module and the support plate, allowing for relative positioning and easy separation without direct adhesion, enabling reuse of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the optical fingerprint sensor module is directly adhered to the self-luminous display panel, then the assembly is compact and stable, but the sensor module cannot be easily separated and reused
Solution Approach 1:
The patent introduces an elastic adhesive layer as an intermediary between the optical fingerprint sensor module and the self-luminous display panel. This elastic adhesive layer enables both stable adhesion during operation and easy separation for reuse, resolving the contradiction between assembly stability and component reusability.
Solution Approach 2:
The patent utilizes the elastic properties of the adhesive layer, which can change its adhesion parameters dynamically. When compressed, the elastic adhesive layer provides strong bonding; when the compression force is removed, it allows for easy separation. This parameter change enables both stable assembly and easy disassembly.
2Ease of repair
If the optical fingerprint sensor module is removed from the self-luminous display panel for repair or replacement, then component reuse is possible, but the sensor module is often damaged during removal
Solution Approach 1:
The elastic adhesive layer serves as a mediator that reduces mechanical stress during removal operations. Its elastic properties allow it to deform and absorb forces that would otherwise damage the sensor module, enabling safe removal and replacement.
Solution Approach 2:
The elastic adhesive layer provides beforehand cushioning by absorbing mechanical stresses during removal operations. This cushioning effect protects the sensor module from damage during the repair or replacement process.
3Stability of the object's composition
If the optical fingerprint sensor module is firmly fixed to the self-luminous display panel, then the assembly is stable, but the components cannot be easily separated for maintenance
Solution Approach 1:
The elastic adhesive layer changes its adhesion parameters based on compression force. Under compression, it provides strong bonding for stability; when compression is removed, it allows easy separation for maintenance operations.
Solution Approach 2:
The elastic adhesive layer introduces dynamic characteristics to the assembly, allowing it to transition between strongly bonded and easily separable states. This dynamic behavior enables both stable operation and easy maintenance.
