Detachable Fingerprint Module Assembly for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In traditional mobile devices, the fingerprint module is difficult to remove and replace without damaging the cover plate, as it is fixed securely, making maintenance and repairs challenging.
Innovation Solution
A shell module design featuring a detachable fingerprint module with a mounting recess and fastener system, allowing for easy assembly and disassembly, where the fingerprint module is embedded in a mounting groove and secured with a fastener, enabling convenient replacement and repair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fingerprint module is fixed securely to the cover plate, then the reliability and stability are improved, but the ease of repair and replacement deteriorates
Solution Approach 1:
The fingerprint module is divided into a separable assembly with the cover plate, allowing the fingerprint module to be detached as an independent unit while maintaining secure connection during operation through the fastening structure
Solution Approach 2:
The connection between the fingerprint module and cover plate is made dynamic through the fastening structure, allowing it to transition between a secured state during operation and a detachable state for maintenance, rather than being permanently fixed
2Stability of the object's composition
If the fingerprint module is fixed securely to the cover plate, then the stability is improved, but the ease of operation for removal deteriorates
Solution Approach 1:
The fingerprint module connection is segmented into modular components including the cover plate, fastening structure, and fingerprint module, enabling stable assembly during operation while allowing easy separation when needed
Solution Approach 2:
The fastening structure provides a dynamic connection that maintains stability during normal operation but allows easy removal through simple fastener operations, eliminating the need for complex disassembly procedures
3Ease of repair
If the fingerprint module is removed from the cover plate, then the ease of repair is improved, but the risk of damage to the cover plate increases
Solution Approach 1:
The fastening structure is pre-configured with fasteners and mounting features that guide the removal process, allowing the fingerprint module to be detached without applying excessive force or causing damage to the cover plate
Solution Approach 2:
The fastening structure acts as an intermediary mechanism between the fingerprint module and cover plate, providing a controlled interface for attachment and detachment that prevents direct force application to the cover plate during removal
