Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As mobile communication and computing 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 a 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 separate biometric authentication device is added to mobile devices, then security is improved, but device size increases
Solution Approach 1:
The patent combines the biometric authentication device with an existing keyboard key, specifically integrating a fingerprint scanner into the spacebar key. This merging approach allows the device to gain biometric security functionality without adding separate external components, thus avoiding increase in overall device volume while improving security through fingerprint-based authentication
2Reliability
If a biometric scanner is integrated into a key, then security is enhanced, but manufacturing complexity increases
Solution Approach 1:
The keyboard key is designed to serve multiple functions: it acts as both a standard keyboard input key and a biometric authentication sensor. The spacebar key incorporates a fingerprint scanner that can be activated alongside or instead of standard key input, allowing the same physical component to fulfill multiple roles and reducing the need for separate dedicated biometric hardware
3Reliability
If additional security components are added, then authentication capability is improved, but battery consumption increases
Solution Approach 1:
The biometric authentication system leverages the existing keyboard infrastructure and processing capabilities already present in the mobile device. The fingerprint scanner integrates with the existing keyboard controller and processor, utilizing existing power management systems and computational resources rather than requiring dedicated power supply circuits and processing units, thereby minimizing additional battery consumption
