Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is used for controlling the wearable device, then the ease of operation is improved, but false triggers occur in noisy environments and voiceprint registration is required
Solution Approach 1:
The patent combines voice recognition with vibration sensor detection to create a hybrid authentication system. The vibration sensor detects characteristic vibrations of the wearer's body (such as heartbeat or body movements) in conjunction with voice commands, thereby improving reliability and reducing false triggers while maintaining ease of operation.
Solution Approach 2:
The vibration sensor acts as an intermediary authentication layer between the user and the voice recognition system. It provides an additional verification mechanism that mediates the authentication process, confirming the wearer's identity through body vibration patterns before executing voice commands, thus reducing false triggers without complicating the user interface.
2Reliability
If voiceprint registration is implemented for accurate voice command recognition, then the reliability is improved, but the device complexity and operation complexity increase
Solution Approach 1:
The vibration sensor enables automatic authentication based on the wearer's natural body vibrations without requiring manual setup or registration. The system continuously monitors vibration patterns and automatically identifies the wearer, eliminating the need for complex voiceprint registration processes while maintaining high reliability.
Solution Approach 2:
The system changes the authentication parameter from complex voiceprint analysis to simpler vibration pattern detection. By monitoring physical vibration characteristics (frequency, amplitude, patterns) of the wearer's body, the system achieves reliable authentication with reduced complexity in both device architecture and user操作流程.
3Reliability
If voiceprint registration is required for accurate recognition, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The vibration sensor performs preliminary authentication by detecting the wearer's body vibrations before voice command processing begins. This preliminary action continuously verifies the wearer's identity in the background, so when a voice command is given, the system can immediately execute it without requiring additional registration or verification steps, thereby maintaining ease of operation while ensuring reliability.
