Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional visual inspections of earthwork structures like slopes and embankments are inefficient, unable to cover large areas within a reasonable time, and fail to quantify surface deformations such as cracks or peeling, posing a risk of road blockages and human injury.
Innovation Solution
An information processing system using a moving object equipped with image capturing devices and sensors to capture and analyze three-dimensional data, combining image and sensor data to evaluate slope conditions, detecting deformations like cracks and bulging, and generating detailed reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional visual inspection methods are used for earthwork structures, then inspection can be performed with simple equipment, but inspection efficiency is low and large areas cannot be covered within reasonable time
Solution Approach 1:
The patent transitions from conventional two-dimensional visual inspection to three-dimensional inspection by mounting image capturing devices on moving objects (drones, vehicles) to capture images from multiple spatial positions and angles, enabling comprehensive coverage of large areas efficiently
Solution Approach 2:
The moving objects equipped with image capturing devices serve multiple functions: they can inspect various types of earthwork structures (slopes, embankments, cuttings) across different terrains and conditions, making the inspection system universally applicable and highly productive
2Measurement precision
If conventional visual inspection methods are used, then equipment complexity is low, but measurement precision of surface deformations is insufficient
Solution Approach 1:
The patent divides the inspection system into multiple components: image capturing devices, sensor devices, information processing devices, and moving objects. Each component performs a specific function, and their coordinated operation achieves high measurement precision for surface deformations while managing system complexity through modular architecture
Solution Approach 2:
The information processing device acts as an intermediary that receives images and sensor data from multiple sources, processes this information to detect surface deformations with high precision, and generates inspection reports. This intermediary component manages the complexity by centralizing data processing and analysis functions
3Reliability
If comprehensive inspection data is collected from multiple sources, then evaluation accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent merges multiple data sources (images from image capturing devices, measurements from sensor devices, positioning information) into a unified inspection system. The information processing device integrates these diverse data types to comprehensively evaluate slope conditions, improving reliability by considering multiple factors simultaneously while managing processing complexity through systematic data fusion
