Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a biological sensor is used to acquire biological information, then measurement capability is provided, but measurement accuracy deteriorates due to insufficient contact between the sensor detection surface and the measurement site
Solution Approach 1:
The patent implements a feedback mechanism where the contact detection unit continuously monitors the contact state between the measurement site and the contact surface, and this information is fed back to control the biological sensor's measurement operation. This ensures that the sensor only performs measurement when reliable contact is confirmed, thereby improving measurement accuracy while maintaining reliable contact.
Solution Approach 2:
The patent performs preliminary contact detection before initiating the biological information measurement. The contact detection unit first verifies that the measurement site is properly contacting the contact surface, and only after confirming reliable contact does it allow the biological sensor to begin measurement. This preliminary action ensures measurement accuracy is not compromised by insufficient contact.
2Measurement precision
If the contact detection unit is integrated with the biological sensor, then device complexity is reduced, but measurement precision deteriorates due to insufficient contact detection capability
Solution Approach 1:
The patent segments the sensor system into two distinct functional units: a contact detection unit and a biological sensor. The contact detection unit is specifically designed to detect contact between the measurement site and the contact surface, while the biological sensor separately performs biological information measurement. This segmentation allows each unit to be optimized for its specific function, improving contact detection precision without excessive complexity.
Solution Approach 2:
The contact detection unit is designed with multi-functionality, serving both as a contact detection mechanism and as a guide for the biological sensor's measurement operation. By making the contact detection unit universal in its function, the patent achieves precise contact detection while avoiding the need for separate complex systems, thus balancing precision with device complexity.
3Measurement precision
If optical sensors and light guide units are added to detect contact, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent introduces an optical sensor as an intermediary element between the contact surface and the measurement system. The optical sensor detects contact through optical signal changes, serving as a mediator that translates physical contact into detectable signals. This intermediary approach improves measurement accuracy by providing reliable contact information, while the integration of the optical sensor with the existing sensor unit keeps the increase in device complexity manageable.
