Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional sensors are added to enhance user experience, then sensor functionality is improved, but device bulkiness increases
Solution Approach 1:
The patent combines multiple functions (power delivery and data communication) into a single integrated connector interface. This merging of functions allows additional sensors to be added without requiring separate bulky connectors for each function, thus enhancing sensor functionality while minimizing device bulkiness.
Solution Approach 2:
The connector is designed to provide multiple functions through a single interface: power delivery, data communication, and sensor integration. This multi-functional design eliminates the need for separate specialized connectors, allowing enhanced sensor capabilities without increasing device volume.
2Device complexity
If conventional power and communication interfaces are used, then device simplicity is maintained, but sensor integration capability is limited
Solution Approach 1:
The connector provides multiple functions (power, data, sensor integration) through a single universal interface, eliminating the need for multiple separate connectors. This maintains device simplicity while significantly enhancing sensor integration capability.
Solution Approach 2:
Multiple interface functions are merged into a single connector that simultaneously provides power delivery, data communication, and sensor integration capabilities, maintaining simplicity while expanding functionality.
3Reliability
If separate power and data connections are provided for each sensor, then communication reliability is improved, but device complexity increases
Solution Approach 1:
Power and data communication channels are merged into a single integrated connector interface. This reduces the number of separate connections while maintaining reliable communication through dedicated channels within the unified interface.
