Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the intensity of the detection beam is increased to extend the detection distance, then the detection distance is improved, but the battery capacity and solar panel size must be increased leading to higher cost
Solution Approach 1:
The patent applies dynamics by making the detection beam intensity adjustable rather than fixed. The transmission unit changes the beam intensity based on environmental conditions (fog, rain, dust) to maintain detection capability without requiring maximum intensity continuously. This dynamic adjustment allows the system to achieve long detection distance when needed while consuming less power under normal conditions, thereby avoiding the need for larger battery capacity and solar panel size.
Solution Approach 2:
The patent changes the parameter of detection beam intensity based on environmental conditions. The control unit receives environmental information and adjusts the beam intensity parameter accordingly - increasing intensity when fog/rain/dust is detected, and reducing intensity under normal conditions. This parameter change enables the system to maintain effective detection distance while optimizing power consumption, thus avoiding the need for increased battery capacity and solar panel size.
2Length of stationary object
If the battery capacity is increased to support higher power consumption, then the detection distance can be extended, but the size of the solar panel must be increased leading to higher cost
Solution Approach 1:
The system dynamically adjusts detection beam intensity based on environmental conditions, consuming high power only temporarily when fog, rain, or dust requires enhanced detection capability. Under normal conditions, the system operates at lower power consumption. This dynamic power management allows the use of a smaller solar panel that can recharge the battery during normal operation, while still providing sufficient power for extended detection distance when environmental conditions require it.
Solution Approach 2:
The control unit changes the detection beam intensity parameter based on environmental sensor input, reducing power consumption under normal conditions and temporarily increasing it when detection distance must be maintained adverse weather. This parameter adjustment enables the system to achieve extended detection capability without requiring a proportionally larger solar panel, as the high-power state is not continuously required.
3Quantity of substance
If the solar panel size is reduced to lower cost, then the battery capacity is insufficient, but the detection distance is shortened
Solution Approach 1:
The system uses dynamic intensity adjustment to match power consumption with actual detection needs. A smaller solar panel charges the battery during normal operation, and the system maintains detection distance by increasing beam intensity only when environmental conditions (fog, rain, dust) require it, rather than continuously operating at high intensity. This dynamic approach allows sufficient battery capacity with a smaller solar panel while maintaining detection distance when needed.
Solution Approach 2:
The control unit adjusts the detection beam intensity parameter based on environmental conditions, allowing the system to maintain adequate battery charge with a smaller solar panel by operating at lower intensity during normal conditions. When detection distance must be maintained adverse weather, the parameter is increased to ensure sufficient detection capability, thus resolving the contradiction between battery capacity and detection distance.
