Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wall detector and digital multimeter are used separately, then each device can perform its dedicated function, but the user workload increases and the detection work becomes cumbersome and complex
Solution Approach 1:
The patent combines wall detection and multimeter functions into a single integrated device. The housing contains both a sensor assembly for wall detection (detecting metal, wood, and electrical wiring) and a multimeter measurement circuit for electrical parameter measurement. This merging eliminates the need to operate two separate devices, directly reducing user workload while maintaining dedicated detection capabilities for each function.
Solution Approach 2:
The integrated detection device achieves multi-functionality by incorporating both wall detection sensors (for locating metal pipes, steel bars, wooden beams, and lighting circuits) and multimeter capabilities (for measuring voltage, current, and resistance). The device can switch between different detection modes, allowing a single device to perform multiple specialized functions that previously required separate tools.
2Reliability
If wall detector and digital multimeter are purchased and carried separately, then each device can be optimized for its specific function, but the purchase cost increases and carrying portability decreases
Solution Approach 1:
The patent merges wall detection and multimeter functions into a single handheld device with a unified housing structure. The sensor assembly for wall detection and the multimeter measurement circuit share the same physical housing, power source, and display interface. This consolidation reduces the total weight and volume compared to carrying two separate devices, while maintaining optimized specialized detection capabilities for each function.
3Weight of moving object
If wall detection assembly and multimeter assembly are integrated in the same housing, then portability improves, but interference between the two functions may occur
Solution Approach 1:
The patent divides the internal housing space into distinct regions: the sensor assembly for wall detection is positioned in one area, while the multimeter measurement circuit is positioned in another area. This spatial segmentation reduces electromagnetic interference between the two functional assemblies while maintaining integration within a single housing, thus improving portability without sacrificing functional independence.

AI summary
This application provides a detection device, which includes a housing, a wall detection assembly, a multimeter assembly, and a circuit setting layer. The wall detection assembly includes a wall detection processing circuit and a sensor assembly. The multimeter assembly includes a multimeter measurement circuit. Both the circuit setting layer and the sensor assembly are located inside the housing. The housing consists of a top housing and a bottom housing that fit together. The circuit setting layer has a first setting surface facing the bottom housing, which includes a first setting area and a second setting area partitioned for different functions. The wall detection processing circuit is located in the first setting area, and the multimeter measurement circuit is located in the second setting area. The sensor assembly is located in the bottom housing and positioned opposite the first setting area. By separating the interfering parts of the wall detection assembly and the multimeter assembly into different areas, the interference and adverse effects between the two different detection functions are isolated, thereby achieving the integration of the wall detection function and the multimeter function into one device without interference.
