Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the range finding module rotates 360 degrees to detect ambient environment, then the detection coverage is improved, but the signal transmission line becomes excessively wound or fractured
Solution Approach 1:
The patent extracts the signal transmission line from the rotating range finding module and places it in the stationary hollow linkage. This separation allows the range finding module to rotate freely for 360-degree detection while the transmission line remains stationary, preventing excessive winding or fracture.
Solution Approach 2:
The patent employs a nested structure where the range finding module is positioned inside the hollow linkage. The hollow linkage serves as both a protective enclosure and a stationary signal transmission conduit, while the range finding module rotates within this nested space to achieve 360-degree coverage without compromising the transmission line.
2Measurement precision
If the range finding module rotates frequently to detect environmental conditions, then the detection accuracy is improved, but the signal transmission line quality deteriorates
Solution Approach 1:
The signal transmission line is extracted from the rotating assembly and placed in the stationary hollow linkage. This allows frequent rotation of the range finding module for accurate environmental detection while the transmission line remains stationary, maintaining signal quality.
3Ease of operation
If the range finding device allows full 360-degree rotation, then the operational capability is improved, but the signal transmission line becomes excessively wound
Solution Approach 1:
The transmission line is extracted from the rotating range finding module and placed in the stationary hollow linkage. This enables full 360-degree rotation for improved operational capability while eliminating the complexity of signal transmission line winding.
Solution Approach 2:
The patent changes the dimensional arrangement by positioning the transmission line in the stationary hollow linkage rather than within the rotating module. This spatial reconfiguration allows 360-degree rotation without line winding complexity.
