Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inputting of contact information is used, then accuracy of information exchange is improved, but time consumption increases
Solution Approach 1:
The system automatically detects skin contact through capacitance sensing and initiates wireless connection and data transfer without requiring user intervention. The mobile device serves itself by autonomously completing the entire information exchange process from detection to transmission, eliminating manual setup while maintaining accurate contact information transfer.
2Reliability
If wireless network connection is manually setup and authorized, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The system pre-establishes skin contact detection capabilities and wireless communication protocols before actual contact occurs. When skin contact is detected, the wireless connection is automatically initiated and authorized based on pre-configured parameters, ensuring reliable connection establishment without requiring manual setup or user authorization at the moment of contact.
3Productivity
If skin-based communication network is used, then data transfer efficiency is improved, but device complexity increases
Solution Approach 1:
The mobile device utilizes its existing capacitance sensing capability, which is already present for touch screen operation, to detect skin contact for communication initiation. The same wireless communication hardware and software infrastructure used for normal wireless operations is repurposed for skin-based activation. This multi-functionality approach enables efficient data transfer through skin contact without adding dedicated specialized components, thereby limiting the increase in device complexity.
