Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are provided for detecting rebars and obstacles, then detection reliability is improved, but device cost and complexity increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single sensor to perform multiple detection tasks. The sensor is configured to detect both rebar positions and obstacles by processing reflection signals differently based on the detection range. When objects are within the first detection range, they are identified as rebars; when beyond this range, they are identified as obstacles. This eliminates the need for separate sensors for rebar and obstacle detection, reducing device complexity while maintaining detection reliability.
2Reliability
If multiple sensors are provided for detecting rebars and obstacles, then detection coverage is improved, but device cost increases
Solution Approach 1:
The patent uses a single sensor that serves multiple purposes: detecting rebars in the first detection range and obstacles in the second detection range. The control unit processes sensor signals to distinguish between rebars and obstacles based on their positions, enabling one sensor to replace what would traditionally require multiple sensors, thereby reducing the quantity of sensors needed while maintaining comprehensive detection coverage.
Solution Approach 2:
The patent extends the detection capability from a single dimension (rebar detection only) to multiple dimensions by introducing a detection range distinction. The first detection range covers the area near the binding device for rebar detection, while the second detection range extends forward to detect obstacles. This dimensional extension allows one sensor to monitor multiple zones with different detection purposes.
