Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wired sensor systems are used in high-temperature environments, then reliable communication can be achieved, but the system weight, cost, and complexity increase due to bulky cable routing and additional cooling components
Solution Approach 1:
The patent replaces traditional mechanical wired sensor systems with electromagnetic waveguide technology. The waveguides transmit both power and data signals wirelessly through electromagnetic fields, eliminating the need for bulky physical cable routing while maintaining communication reliability in high-temperature environments.
Solution Approach 2:
The waveguide structure serves multiple functions simultaneously: it acts as an electromagnetic transmission medium for communication, a power delivery conduit, and a thermal management pathway. By integrating these functions into a single structure, the system reduces overall weight and complexity compared to separate systems for each function.
2Reliability
If additional active cooling components are added to protect electronic components, then component reliability improves, but power consumption and system complexity increase
Solution Approach 1:
The waveguide system provides self-cooling by directing ambient or cooled air flow through its internal passages, eliminating the need for separate active cooling components like fans or heat sinks. The structure itself serves as the cooling pathway, reducing power consumption while maintaining component reliability.
Solution Approach 2:
The cooling function is merged with the electromagnetic transmission function by integrating air cooling passages within the waveguide structure. This combination eliminates the need for separate cooling systems, reducing both power consumption and system complexity while protecting electronic components.
3Adaptability or versatility
If wire routing is extended to reach difficult-to-access sensor locations, then sensor coverage improves, but cable volume, cost, and vulnerability to interconnect failures increase
Solution Approach 1:
The patent replaces mechanical cable extensions with electromagnetic waveguide transmission. The waveguides can transmit signals to difficult-to-access locations without requiring physical cable routing, significantly reducing cable volume while improving sensor coverage and eliminating vulnerability to interconnect failures.
4Adaptability or versatility
If multiple sensors and effectors are deployed with varying signal path lengths, then system functionality improves, but fault detection and normal operation become more challenging
Solution Approach 1:
The waveguide system uses electromagnetic parameters (frequency, wavelength, propagation characteristics) to manage signal transmission to multiple sensors and effectors. By controlling electromagnetic parameters rather than physical cable lengths, the system achieves versatile functionality while simplifying fault detection through consistent signal characteristics regardless of path length variations.
