Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate identification tag is embedded into the rubber, then the tire can be identified, but the manufacturing complexity increases and the tag can be removed
Solution Approach 1:
The patent combines the identification tag and pressure sensor into a single integrated electronic component that is embedded within the tire rubber. This merging eliminates the need for separate identification tags, reducing manufacturing complexity while maintaining identification security through the integrated design.
Solution Approach 2:
The electronic component serves multiple functions simultaneously: it acts as both an identification tag and a pressure sensor. This multi-functionality reduces the number of separate components needed, simplifying manufacturing while ensuring reliable identification and pressure monitoring.
2Measurement precision
If a cavity or pipe solution is used for pressure sensor access, then the pressure sensor can measure tire pressure, but the manufacturing complexity increases
Solution Approach 1:
The pressure sensor is integrated directly into the electronic component that is embedded within the tire rubber, eliminating the need for separate cavities or pipes. This integration simplifies the manufacturing process while maintaining accurate pressure measurement capability through the embedded sensor design.
Solution Approach 2:
The invention extracts the pressure sensor from a separate cavity or pipe structure and embeds it directly within the electronic component in the rubber. This extraction eliminates the complex cavity/pipe solutions while preserving the sensor's ability to measure tire pressure accurately.
3Device complexity
If the electronic part is embedded into the rubber, then the system structure is simplified, but the manufacturing process becomes more challenging
Solution Approach 1:
The electronic component is pre-assembled with the pressure sensor and identification elements before being embedded into the tire rubber during the curing process. This preliminary assembly simplifies the manufacturing process by reducing the number of separate steps required, making the embedding process more manageable while achieving a simplified final structure.
