Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors are placed on the wrist to measure body temperature, then the measurement can be obtained, but the measurement accuracy deteriorates due to external factors like hand washing
Solution Approach 1:
The patent transitions from measuring body temperature at the wrist (one dimension) to measuring at the nose bridge (another dimension/location). The temperature sensor is positioned on the nose bridge of the glasses frame, which is a different anatomical location that is less susceptible to external factor contamination, thereby improving measurement accuracy while maintaining wearability.
Solution Approach 2:
The glasses frame acts as an intermediary carrier that positions the temperature sensor close to the user's skin at the nose bridge. This intermediary structure enables accurate temperature measurement without requiring direct contact with the wrist, thus avoiding the harmful effect of hand washing while maintaining measurement capability.
2Measurement precision
If temperature sensors are positioned close to the skin on the inner sides of the glasses frame, then measurement accuracy improves, but the device complexity increases
Solution Approach 1:
The glasses frame serves multiple functions: it provides the structural support for the smart glasses, acts as a mounting structure for the temperature sensor, and positions the sensor optimally close to the user's skin at the nose bridge. This multi-functionality reduces device complexity by eliminating the need for separate positioning mechanisms while achieving accurate measurement.
Solution Approach 2:
The temperature sensor is merged with the glasses frame structure, integrating the sensing function into the existing framework. This combination simplifies the overall device architecture by avoiding separate sensor mounting systems and ensures consistent positioning of the sensor relative to the user's face and skin.
