Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If large-volume metallic components and threaded connections are used in the multimeter detection part, then the structural strength and ease of manufacture are improved, but the detection accuracy and reliability of the wall detection part deteriorate due to interference from metallic components
Solution Approach 1:
The detection device is divided into functionally independent modules: the wall detection assembly and the multimeter assembly. Each module operates independently within its own spatial zone, reducing mutual interference. The wall detection sensing elements are positioned in a dedicated detection area away from metallic components of the multimeter assembly.
Solution Approach 2:
The sensing elements for wall detection are extracted and positioned in a location separated from the metallic components of the multimeter assembly. This spatial extraction eliminates the harmful electromagnetic interference from large-volume metallic components while maintaining the structural integrity of both modules.
2Ease of manufacture
If threaded connections and metallic fasteners are used to fix components, then the ease of manufacture and assembly are improved, but the detection accuracy deteriorates due to interference from metallic fasteners
Solution Approach 1:
Non-metallic fastening elements (such as plastic screws or polymer-based connectors) are introduced as intermediary components to replace metallic fasteners in the wall detection assembly. These non-metallic intermediaries eliminate electromagnetic interference while maintaining the mechanical fastening function, allowing easy assembly without compromising detection accuracy.
3Volume of moving object
If the sensing assembly is positioned close to the multimeter assembly for compact design, then the device volume is reduced, but the detection accuracy deteriorates due to interference from metallic components
Solution Approach 1:
The sensing elements are positioned in a spatial dimension that maximizes distance from metallic components while maintaining overall device compactness. The wall detection assembly and multimeter assembly are arranged in a three-dimensional layout where the sensing area is separated along a specific axis, reducing interference while minimizing the overall device footprint.
