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 allows for secure biometric authentication without compromising device size or functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a biometric input device is integrated into a key, then security is enhanced, but device complexity increases
Solution Approach 1:
The biometric input device is merged with a key to form an integrated unit. The biometric input device and key share common structural elements, including a single actuation mechanism that simultaneously operates both the key function and biometric scanning function, thereby enhancing security while managing complexity through integration
2Volume of moving object
If device size is reduced for portability, then mobility is improved, but space for biometric security features is reduced
Solution Approach 1:
The biometric input device is integrated into the key structure, allowing both functions to share the same physical space. This merging enables compact device design while maintaining biometric security capabilities, as the key and biometric scanner occupy overlapping spatial volumes rather than requiring separate allocations
Solution Approach 2:
The key is designed to serve multiple functions: traditional keypress operation and biometric input. This multi-functionality allows the device to maintain security features in a compact form factor, as the same structural element performs both key activation and biometric scanning without requiring additional dedicated space
