Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanical displacement device is used to move probes and object relative to each other to generate angular spread statistic, then the ability to generate realistic electromagnetic scenarios is improved, but the device complexity increases
Solution Approach 1:
The patent applies dynamics by making the probe or object movable through a mechanical displacement device that enables real-time angular movement around the principal aiming direction. This dynamic capability allows the system to generate electromagnetic radiation with variable angular spread statistics, transforming a static testing setup into a dynamic one that can reproduce realistic propagation conditions.
Solution Approach 2:
The mechanical displacement device acts as an intermediary between the control system and the electromagnetic radiation generation. It translates control signals into precise angular positions of the probe or object, enabling indirect control of the electromagnetic field characteristics through mechanical movement rather than direct electronic control of the radiation source.
2Measurement precision
If electromagnetic radiation with variable angular spread is generated by moving probes, then the measurement precision of temporal response is improved, but the ease of operation deteriorates
Solution Approach 1:
The system employs feedback through a control element that receives information about the angular spread statistic and adjusts the mechanical displacement device accordingly. This feedback loop ensures that the desired angular spread is achieved and maintained, improving measurement precision while automating the complex coordination required for multi-probe movement.
Solution Approach 2:
The patent changes the parameter of angular position dynamically by moving the probe or object through prescribed trajectories. By varying the angular spread statistic as a time-dependent parameter, the system achieves more accurate temporal response measurements that reflect real-world conditions where signal arrival angles change over time.
3Reliability
If multiple probes are used to cover all electromagnetic scenarios, then the completeness of testing is improved, but the productivity decreases
Solution Approach 1:
Instead of using a large number of fixed probes, the patent employs a smaller number of probes that are dynamically moved to different angular positions. This dynamic approach allows the same physical probes to cover multiple spatial positions and angular spread scenarios sequentially, achieving complete testing coverage with fewer physical components and improved productivity.
