Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If contactless radar system is used for positioning and movement control, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The patent replaces contact-based mechanical positioning systems with a contactless radar-based measurement system. The radar system uses electromagnetic waves to detect the position and movement of tools relative to the wheel, eliminating the need for physical contact sensors and their associated mechanical linkages, thereby improving measurement precision while reducing mechanical complexity.
Solution Approach 2:
The radar system acts as an intermediary between the control system and the physical tools. It provides non-contact measurement data that enables precise control of tool positioning and movement without requiring direct physical interaction between sensors and the wheel assembly, resolving the contradiction between precision and complexity.
2Device complexity
If traditional contact-based sensors are used, then device complexity is reduced, but measurement precision and reliability deteriorate due to sensor limitations and environmental conditions
Solution Approach 1:
The patent substitutes contact-based mechanical sensors with a contactless radar system. This replacement eliminates reliability issues associated with physical contact sensors such as wear, contamination, and sensitivity to environmental conditions, while maintaining relatively simple system architecture through the use of modern radar technology.
3Loss of time
If physical contact sensors are used for tool positioning, then processing time is reduced, but measurement precision deteriorates due to sensor exposure and latency
Solution Approach 1:
The radar system provides rapid electromagnetic wave-based measurements that eliminate the exposure and latency issues inherent in contact-based sensing systems. The contactless nature of radar allows for instantaneous position detection without the mechanical response delays associated with physical sensors, achieving both fast processing and high precision.
