Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If light sensor systems are used for aerial ropeway monitoring, then the system can detect hazards, but the system is prone to malfunction during harsh weather conditions like snow or rain
Solution Approach 1:
The patent replaces optical sensing systems with radar-based sensing systems. Radar uses electromagnetic waves (radio waves) instead of light to detect hazards along the aerial ropeway. This substitution resolves the contradiction because radar waves can penetrate through snow, rain, and other harsh weather conditions that block light sensors, thereby maintaining reliable hazard detection functionality while eliminating weather interference.
2Reliability
If radar-based sensing is used instead of light sensors, then weather interference is eliminated, but the device complexity increases
Solution Approach 1:
The patent introduces a radar sensor as an intermediary device that emits electromagnetic waves and receives reflected signals to detect hazards. The radar sensor acts as a mediator between the control system and the environment, providing reliable hazard detection through electromagnetic wave interaction with target objects. This intermediary approach resolves the contradiction by using radar technology that inherently penetrates weather conditions while managing system complexity through dedicated sensor functionality.
3Reliability
If comprehensive hazard detection is implemented, then safety functions are improved, but the measurement precision requirements increase
Solution Approach 1:
The patent changes the detection parameters from optical to electromagnetic wave-based measurements. Radar systems measure hazards using parameters such as distance, velocity, and angular orientation through electromagnetic wave propagation characteristics. This parameter change resolves the contradiction by providing comprehensive hazard detection capabilities that are inherently precise for safety-critical applications, as radar can accurately measure position and motion parameters even in harsh weather conditions where optical systems fail.
