Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If plate-shaped conductors are used to increase rainwater sensing areas, then detection accuracy is improved, but the device occupies more space and reduces efficiency
Solution Approach 1:
The patent divides the sensing area into multiple discrete sensing regions by spacing apart multiple plate-shaped conductors on the panel surface. This segmentation allows rainwater to be detected at multiple locations simultaneously, improving overall detection accuracy while maintaining efficient use of panel space.
Solution Approach 2:
The patent arranges plate-shaped conductors in a three-dimensional configuration on the panel surface, utilizing both horizontal and vertical spacing. This multi-dimensional arrangement increases the effective sensing volume without proportionally increasing the panel area occupied, thereby improving detection accuracy while space efficiency.
2Reliability
If the panel is installed at a predetermined angle with the ground to detect rainwater flow, then rainwater detection is enabled, but the device cannot properly detect rainwater when wind blows away from the panel
Solution Approach 1:
The patent designs the rainwater detection device with multiple sensing regions distributed across the panel surface, enabling it to detect rainwater effectively under various installation angles and wind conditions. This multi-functional configuration allows the device to adapt to different environmental conditions, including situations where wind blows away from the panel.
Solution Approach 2:
The patent creates a dynamic detection system where multiple sensing regions can detect rainwater from different directions and angles. This dynamic configuration allows the device to maintain detection reliability regardless of panel installation angle or wind direction, as at least some sensing regions will remain effective under any given condition.
3Ease of manufacture
If the panel is installed parallel to the ground for easier installation, then installation simplicity is improved, but rainwater droplets formed directly on the panel cannot be detected
Solution Approach 1:
The patent segments the panel surface into multiple sensing regions with spaced-apart conductors, creating detection zones that can identify rainwater droplets forming directly on the panel surface. This segmentation enables the system to detect droplets at multiple locations simultaneously, maintaining detection precision even when the panel is installed parallel to the ground.
Solution Approach 2:
The patent uses multiple plate-shaped conductors arranged to create overlapping or adjacent sensing regions, providing excessive coverage of the panel surface. This ensures that rainwater droplets forming at any location on the panel will be detected, even when the panel is installed parallel to the ground, thereby maintaining detection precision while simplifying installation.
