Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual wiring is used between the control unit and the detecting device, then the detecting device can be positioned at the free end of the screening body, but the manufacturing process becomes complex and laborious
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication system. The detecting device communicates with the control unit via wireless signals (e.g., radio frequency), eliminating the need for physical wire connections. This substitution resolves the contradiction by maintaining detection capability while completely removing the manufacturing complexity associated with manual wiring and wire guidance.
2Reliability
If wires are manually guided through the tubular element, then the detecting device can be connected to the control unit, but the construction time increases significantly
Solution Approach 1:
The patent eliminates the mechanical wire guidance system entirely by implementing wireless communication between the control unit and the detecting device. This removes the time-consuming manual wire guidance step from the construction process while maintaining reliable communication through electromagnetic signals, thus resolving the contradiction between connection reliability and construction time.
3Volume of moving object
If the overall size of the screening device is minimized, then the device becomes more compact, but wiring space becomes insufficient
Solution Approach 1:
The patent replaces the physical wiring infrastructure with wireless communication technology. This eliminates the need for dedicated wiring channels and spaces within the compact device structure. The detecting device and control unit communicate through wireless signals, allowing the device to maintain a minimized overall size without compromising connectivity, thus resolving the contradiction between device compactness and wiring space availability.
4Reliability
If manual wire guidance is used, then connections can be established, but the process becomes more laborious and error-prone
Solution Approach 1:
The patent substitutes the manual wire guidance process with automated wireless communication setup. The detecting device and control unit automatically establish communication through wireless protocols without requiring manual intervention for wire routing and connection. This eliminates human error in wire guidance while dramatically improving assembly efficiency, as the devices can be assembled in any configuration without worrying about wire routing, thus resolving the contradiction between connection reliability and assembly efficiency.
