Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are arranged inside the device to improve control, then measurement accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple sensors into a single integrated sensor system that is arranged in close proximity to the tobacco article. This merging approach allows multiple sensing functions to be performed by a unified structure, reducing overall device complexity while maintaining measurement accuracy through the integrated design.
Solution Approach 2:
The sensor system is designed to perform multiple measurement functions simultaneously, making it a multi-functional component. This universal approach allows a single sensor arrangement to provide various measurements (temperature, position, etc.) that would traditionally require separate sensors, thereby reducing device complexity while improving control capabilities.
2Measurement precision
If multiple sensors are arranged inside the device to improve control, then measurement accuracy is improved, but cost increases
Solution Approach 1:
By merging multiple sensing functions into a single integrated sensor system, the patent reduces the total number of components that need to be manufactured and assembled. This consolidation lowers manufacturing costs while maintaining the measurement accuracy benefits of having multiple sensing capabilities through the unified sensor design.
3Measurement precision
If sensors are arranged in respect with the tobacco article to improve measurement accuracy, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The sensor system is positioned in close proximity to the tobacco article to provide localized, high-accuracy measurements. This local placement strategy ensures that sensors are where they are most needed for accurate tobacco article monitoring, while the integrated design of the sensor system prevents this localized arrangement from increasing overall device complexity.
