Solution Overview
Problem
Conventional buried object scanning devices require marking on the concrete surface, increasing operator workload during the search process.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If marking work is performed on the concrete surface to define scanning ranges, then the operator can accurately identify scanning areas and buried object positions, but the operator workload and time consumption increase significantly
Solution Approach 1:
The patent creates a virtual copy of the physical scanning environment by generating a search image that represents the scanned area and overlaying it with a grid layer. This virtual representation allows operators to identify buried object positions and scanning ranges without performing physical marking work on the concrete surface, thereby reducing operator workload while maintaining position identification accuracy.
Solution Approach 2:
The patent replaces the mechanical marking process (physically marking the concrete surface with tape or other markers) with an electronic/digital system. The search image and grid layer are generated and displayed through a display unit, substituting the mechanical marking action with electronic image processing and display, which eliminates the need for physical marking materials and reduces operator burden.
2Productivity
If marking work is performed on the concrete surface, then scanning ranges can be clearly defined, but the process becomes more complex and time-consuming
Solution Approach 1:
The patent makes the display unit serve multiple functions: it displays the search image showing buried object detection results, overlays the grid layer for position reference, and enables dragging operations for interactive exploration. This multi-functional display approach eliminates the need for separate marking tools and processes, simplifying the overall workflow while maintaining scanning range definition capabilities.
Solution Approach 2:
The patent implements a dynamic interaction model where the search image can be dragged relative to the grid layer, allowing operators to dynamically adjust and explore different viewing perspectives. This dynamic capability replaces static physical markings with flexible digital manipulation, reducing process complexity while enabling comprehensive search area analysis.

AI summary
A buried object scanning device includes a capacitance sensor, a search image conversion processing unit, a memory unit, a display unit, an operation input unit, and a display control unit. The capacitance sensor detects a buried object. The search image conversion processing unit converts the detection result of the capacitance sensor into a search image. The memory unit stores search images and a grid layer including grid lines corresponding to a specific scale. The display unit displays the search images and the grid layer. The display control unit controls the display unit to display the search image superimposed with the grid layer and to display the search image in a state of being movable relative to the grid layer, in response to input to the operation input unit.
