Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing construction assistance data for underground buried objects during excavation has excessive data amounts due to rich information, making it difficult for users to understand the position and posture of these objects and control construction machines to avoid contact.
Innovation Solution
A construction assistance device that generates data by measuring depth positions in multiple underground search areas, consolidating them into representative positions, and reducing data amount by arranging objects in individual areas, allowing for easier understanding and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If construction assistance data includes rich information about underground buried objects, then the information completeness is improved, but the data amount becomes excessive
Solution Approach 1:
The patent segments the underground search area into multiple divided areas and assigns one object representing the buried object to each divided area. This segmentation approach maintains comprehensive spatial information about buried objects while reducing the overall data amount by consolidating multiple measurement points into representative objects per area.
2Measurement precision
If construction assistance data represents detailed depth positions in all search areas, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent extracts representative depth position information from multiple measurement points within each divided area, consolidating detailed measurement data into essential representative values. This extraction process maintains the necessary precision for construction safety while significantly reducing data processing complexity.
3Reliability
If construction assistance data includes comprehensive underground search results, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent applies local quality by assigning specific objects representing buried objects to individual divided areas, allowing operators to easily locate and understand buried object positions in specific areas. This localized representation maintains comprehensive safety information while improving ease of operation through intuitive spatial organization.

AI summary
There is provided a device, etc. that generates construction assistance data that can be used for generating an image that allows a user to easily understand a position and posture of an underground buried object, and for controlling operation of a construction machine to avoid contact with the buried object. In at least part of a plurality of underground search areas Si1, Si2, . . . , Sim, Sim+1, underground search points P1, . . . . Pi−1, Pi, Pi+1, . . . . Pn−1, Pn of the underground buried objects each have a depth position from the ground surface, measured by an underground search machine 60, and the depth positions are consolidated into a representative depth position. Then, construction assistance image data is generated that represents a three-dimensional image including closed surfaces m1, m2 as objects each representing the representative depth position arranged at each of the plurality of underground search areas Si1, Si2, . . . , Sim, Sim+1.
