Construction Machine Display for Obstacle Detection and Distance Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction machines, such as excavators, suffer from blind spots that cannot be seen by the operator, leading to reduced work efficiency due to the need to rely on mirrors or direct visual checks, and existing camera systems only display images without providing obstacle distance information.
Innovation Solution
A display system comprising an obstacle detecting system that uses sensors and cameras to identify obstacles within a certain range, generating information on location, direction, and system status, displayed on a unit that visually indicates these details to the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If cameras are installed on the left and right sides or rear of the upper rotating body to detect obstacles, then obstacle detection capability is improved, but the system only displays images without providing distance information, resulting in incomplete obstacle information
Solution Approach 1:
The patent combines multiple detection functions (image capture and distance measurement) into a single integrated obstacle detection system. The imaging unit captures visual information while the distance measuring unit simultaneously measures distance to the same obstacle, merging these functions to provide complete obstacle information (location, direction, and distance) through a unified system rather than separate systems
Solution Approach 2:
The obstacle detection system is designed to perform multiple functions simultaneously: capturing images of obstacles, measuring distance to obstacles, determining obstacle direction, and displaying all this information through the display unit. This multi-functional approach allows a single system to provide comprehensive obstacle awareness including visual images and quantitative distance data
2Productivity
If the operator relies on mirrors or direct visual checks to monitor blind spots, then no additional detection equipment is needed, but work efficiency deteriorates due to the need to constantly check mirrors and blind spots
Solution Approach 1:
The system provides automatic obstacle detection and information presentation without requiring the operator to manually check mirrors or blind spots. The imaging unit automatically captures images, the distance measuring unit automatically measures distances, and the display unit automatically presents this information, allowing the system to serve itself in monitoring blind spots while the operator focuses on primary work tasks
Solution Approach 2:
The system provides continuous feedback to the operator about obstacles in blind spots through the display unit, which shows images and distance information. This feedback loop allows the operator to be immediately informed of obstacles without manually checking, improving both productivity and ease of operation by eliminating the need for constant manual monitoring
