Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional methods (dummies, plastic bags, sounds) are used to repel animals, then the device complexity is low, but the repelling effect is limited and ineffective
Solution Approach 1:
The system segments the repelling function into multiple independent modules: infrared detection module, control module, and water spraying module. This segmentation allows each module to perform its specific function efficiently while maintaining overall system reliability for animal repulsion.
Solution Approach 2:
The patent introduces water as an intermediary substance to enhance the repelling effect. The water spraying module uses water particles as a physical barrier and deterrent, significantly improving the reliability of animal repulsion compared to traditional methods.
2Adaptability or versatility
If a fixed water outlet is used, then the device complexity is low, but the sprinkling coverage and adaptability to different animals are limited
Solution Approach 1:
The water outlet device is made dynamic through the universal joint connection, allowing it to rotate and adjust its spraying direction. This dynamic capability enables the system to adapt to animals at different positions and distances, significantly improving sprinkling coverage and versatility.
Solution Approach 2:
The universal joint mechanism provides multi-directional spraying capability, making the water outlet device universal in its coverage area. It can effectively repel animals whether they are nearby or in the distance, regardless of their position relative to the device.
3Productivity
If continuous spraying is used for irrigation, then the irrigation effectiveness is high, but water resources are wasted and it cannot serve both irrigation and repelling functions efficiently
Solution Approach 1:
The control module implements periodic spraying action based on infrared detection. Instead of continuous spraying, the system activates the water outlet only when animals are detected, creating a periodic action pattern that maintains irrigation effectiveness while dramatically reducing water resource waste.
Solution Approach 2:
The infrared detection module provides feedback about the presence of animals to the control module. This feedback mechanism enables the system to intelligently control the spraying timing, ensuring water is used effectively for both irrigation and animal repulsion without unnecessary waste.
