Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera device works in rainy, snowy or wet, cold environment, then the autonomous moving device can operate in various weather conditions, but water mist condenses on the camera device affecting photographing function
Solution Approach 1:
The heating module is activated in advance when cold or wet weather conditions are detected by the controller, preventing water mist condensation before it occurs on the camera lens. This proactive heating approach maintains the lens temperature above dew point, ensuring continuous photographing functionality without interruption.
Solution Approach 2:
The heating module acts as an intermediary element between the camera device and the adverse environmental conditions. By introducing thermal energy as a mediating factor, the system counteracts the condensation-forming conditions, allowing the camera to function reliably in weather conditions that would otherwise cause malfunction.
2Device complexity
If the health state of vegetation is identified by using naked eyes, then no additional equipment is needed, but the identification accuracy is insufficient and professional knowledge is required
Solution Approach 1:
The patent replaces the mechanical/visual inspection method (naked eye observation) with an optical detection system (camera device). The camera captures images that are then processed to extract vegetation health information, substituting human visual assessment with automated image analysis that does not require professional knowledge while providing higher measurement precision.
Solution Approach 2:
The system enables self-service vegetation monitoring where the camera device automatically captures images and the processing system automatically analyzes vegetation health status. This eliminates the need for human experts to perform manual inspection, allowing ordinary users to obtain accurate vegetation health assessments without requiring professional agricultural knowledge.
3Ease of operation
If manual nurturing is performed by user, then direct care is provided to vegetation, but the work is time-consuming and labor-consuming
Solution Approach 1:
The system implements self-service vegetation monitoring and assessment. The camera device automatically and continuously monitors vegetation health, eliminating the need for manual inspection. The automated image processing and health assessment functions allow the system to perform nurturing tasks independently, saving significant time and labor while maintaining direct care capability.
Solution Approach 2:
The system establishes a feedback loop where the camera continuously monitors vegetation conditions, the processing system analyzes the images to detect health changes, and nurturing actions are triggered automatically based on the analysis results. This closed-loop feedback mechanism enables timely intervention without requiring continuous manual monitoring, reducing both time loss and labor requirements while maintaining effective vegetation care.
