Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large-sized sensor module with fine structures is embedded in elastomer material, then sensing capability is improved, but manufacturing precision deteriorates due to bubbles and defects
Solution Approach 1:
The sensor system is divided into two separate parts: a compact sensor module that can be easily embedded in elastomer material, and a separate booster antenna that is applied afterward. This segmentation allows the sensor module to be small and simple (reducing manufacturing defects) while the booster antenna provides the necessary communication range (maintaining sensing capability).
Solution Approach 2:
The sensor module is embedded in the elastomer material before vulcanization, allowing it to withstand the high temperatures and pressures of the vulcanization process. The booster antenna is then applied afterward, avoiding exposure to harsh manufacturing conditions and preventing manufacturing defects.
2Manufacturing precision
If a compact sensor module is embedded in elastomer material, then manufacturing precision is improved, but reading range deteriorates due to limited communication distance
Solution Approach 1:
The booster antenna acts as an intermediary between the compact sensor module and external reading devices. It receives electromagnetic signals from the sensor module and retransmits them with increased power, extending the reading range without requiring the sensor module itself to be large or complex.
3Strength
If a sensor module is embedded deep within elastomer material, then protection is improved, but data transfer efficiency deteriorates due to signal attenuation
Solution Approach 1:
The booster antenna serves as an intermediary that compensates for signal attenuation caused by deep embedding. It receives weak signals from the sensor module and amplifies them for external transmission, maintaining data transfer efficiency despite the sensor module's protected position within the elastomer material.
