Spacebar Fingerprint Scanner Integration for Compact Keyboards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile communication devices become smaller, there is a challenge in integrating biometric security features due to limited space, necessitating a compact solution for secure authentication.
Innovation Solution
A keyboard with at least one key that integrates a biometric input device, such as a fingerprint scanner, like the spacebar key, which includes scanner components and controlling circuits, allowing for secure biometric authentication without increasing device size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a biometric input device is integrated into a keyboard key, then security is enhanced, but device size increases
Solution Approach 1:
The biometric input device is merged with an existing keyboard key structure, combining two separate functions (keyboard input and biometric authentication) into a single integrated component. This eliminates the need for separate biometric sensors that would increase device volume, while maintaining enhanced security through fingerprint scanning capability integrated into the key.
2Reliability
If a biometric input device is integrated into a keyboard key, then security is enhanced, but manufacturing complexity increases
Solution Approach 1:
The keyboard key is designed to serve multiple functions: standard keyboard input and biometric authentication. By making the key structure universal and multi-functional, the patent avoids the need for separate dedicated biometric sensor assemblies, thereby reducing manufacturing complexity while still providing enhanced security through integrated fingerprint scanning.
3Reliability
If a biometric input device is integrated into a keyboard key, then security is enhanced, but repair difficulty increases
Solution Approach 1:
The integrated key structure is designed as a segmented, modular component that can be independently removed and replaced. The biometric input device is integrated into the key in such a way that the entire key assembly can be swapped as a single unit without affecting other keyboard components, simplifying repair processes while maintaining enhanced security functionality.
