Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If human body communication is used for data transfer, then power consumption is reduced compared to radio communication, but the authentication process becomes more complex requiring multiple user interventions
Solution Approach 1:
The patent combines touch detection and biometric authentication into a unified process. When a user touches both electronic devices simultaneously, the system detects the touch event on both devices and automatically initiates authentication using biometric data from the touch, merging what were previously separate actions into one integrated operation.
Solution Approach 2:
The system performs authentication automatically using biometric data captured from the touch interaction itself. The biometric authentication is executed without requiring additional user actions beyond the simultaneous touch, allowing the system to self-complete the authentication process based on the physical interaction already occurring.
2Reliability
If multiple authentication steps are implemented for security, then reliability is improved, but ease of operation deteriorates due to cumbersome user actions
Solution Approach 1:
The patent merges multiple authentication requirements into a single simultaneous touch action. The system detects touch events on both devices at the same time and uses biometric data from this unified interaction to complete authentication, maintaining security while eliminating the need for separate authentication steps.
Solution Approach 2:
The patent replaces traditional mechanical authentication methods (keyboards, pattern locks, password entry) with biometric authentication based on touch characteristics. This substitution maintains or improves security while significantly simplifying the user interaction required.
3Reliability
If explicit user actions are required for each transfer step, then control and security are maintained, but productivity decreases due to multiple navigation steps
Solution Approach 1:
The system automatically manages the data transfer process after detecting simultaneous touch events. Applications on both devices can identify and transfer items without additional user navigation or selection, allowing the transfer to complete itself while maintaining security through the initial biometric authentication.
Solution Approach 2:
The system performs preliminary authentication and item identification during the simultaneous touch event itself. By completing authentication and determining transfer parameters before the actual data transfer begins, the system enables rapid execution without requiring users to navigate through multiple screens during the transfer process.
