Keyboard With Integrated Fingerprint Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fingerprint authentication systems in keyboards and mobile devices are limited by low security and lack of versatility, as they typically use a single fingerprint identification device, which can be easily compromised and does not accommodate multiple users or multiple fingerprints effectively.
Innovation Solution
A keyboard design incorporating multiple fingerprint identification modules integrated into key caps, connected to a microprocessor and circuit board, allowing for secure authentication and supporting multiple users or multiple fingerprints, with an aluminum board providing structural support and pivotal seating for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single fingerprint identification device is used for authentication in mobile phones, tablet computers, laptop computers and keyboards, then the device complexity is reduced, but the security and versatility are lowered
Solution Approach 1:
The patent divides the authentication system into multiple independent fingerprint identification modules, each capable of storing and verifying different fingerprints. This segmentation allows the system to support multiple users and multiple fingerprints per user, thereby improving security and versatility without significantly increasing overall system complexity.
Solution Approach 2:
The keyboard is designed with multiple fingerprint identification modules that can serve multiple functions: authenticating multiple different users, storing multiple fingerprints per user, and providing both security authentication and user identification capabilities. This multi-functionality resolves the contradiction by enhancing reliability while maintaining reasonable device complexity.
2Reliability
If multiple fingerprint identification modules are integrated into key caps, then the authentication security and versatility are improved, but the device complexity increases
Solution Approach 1:
The patent combines the fingerprint identification modules with the existing key cap structure, integrating the authentication functionality into the keyboard's mechanical framework. This merging approach allows multiple fingerprint modules to be incorporated without requiring separate authentication devices, thereby improving security while controlling the increase in device complexity.
Solution Approach 2:
The keyboard structure is designed to serve dual purposes: as a functional keyboard and as a multi-fingerprint authentication device. The key caps incorporate fingerprint identification modules, allowing the same structure to perform both typing and security authentication functions, thus improving reliability without proportionally increasing complexity.
3Reliability
If multiple fingerprint identification modules are integrated into key caps, then the authentication security and versatility are improved, but the manufacturing complexity increases
Solution Approach 1:
The fingerprint identification modules are designed as separate, modular components that can be independently manufactured and then integrated into the key caps. This segmentation allows for specialized manufacturing of the fingerprint modules using precise molding techniques, while the overall keyboard assembly process remains relatively simple and scalable.
Solution Approach 2:
The key cap design integrates multiple functions (mechanical key function and fingerprint authentication) into a single manufactured component. By designing the key caps to accommodate fingerprint modules during the molding process, the patent enables simultaneous production of both the mechanical structure and the authentication functionality, improving reliability while maintaining ease of manufacture through integrated molding techniques.
