Construction Machine Guidance Display Integrating Obstacle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction machine operators face difficulties in responding promptly to obstacle information while using guidance apparatuses, leading to inefficiencies in work efficiency and convenience due to the need to constantly monitor screens during operations like excavating slope faces or leveling land surfaces.
Innovation Solution
A construction machine equipped with a guidance apparatus that acquires and displays design data and positional information of the work implement, along with an obstacle detecting apparatus that provides real-time positional information of obstacles on the same monitor, allowing operators to focus on the guidance screen without missing obstacle alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the operator uses the guidance apparatus to monitor the screen during excavation operations, then work precision and guidance accuracy are improved, but the operator's response time to obstacle information deteriorates
Solution Approach 1:
The patent combines the guidance apparatus display and obstacle detection display into a single integrated display unit. The guidance information (target excavation surface, work implement position) and obstacle information (intrusive objects, warning zones) are superimposed on the same screen, allowing the operator to simultaneously access both types of information without switching between multiple displays, thus maintaining work precision while improving response time to obstacles
Solution Approach 2:
The display unit is designed to serve multiple functions: it displays both guidance information for precise excavation work and obstacle warning information for safety monitoring. By making the display system multi-functional, the operator can monitor both work precision parameters and obstacle positions through a single interface, resolving the contradiction between maintaining precision and responding quickly to obstacles
2Measurement precision
If separate monitoring systems are used for guidance and obstacle detection, then information accuracy for each function is improved, but device complexity and operator workload increase
Solution Approach 1:
The patent merges the guidance apparatus and obstacle detection apparatus into an integrated system with a shared display unit. Both systems maintain their independent sensing and processing capabilities for accurate measurement, but their output is combined on a single display screen, reducing the number of separate monitoring devices the operator must manage while preserving the measurement precision of each subsystem
Solution Approach 2:
The display unit is designed as a universal interface that handles multiple types of information simultaneously. It displays guidance data (target surfaces, work implement positions) and obstacle data (detected objects, warning areas) with equal clarity, allowing one display system to perform the functions previously requiring separate dedicated displays, thereby reducing device complexity while maintaining information accuracy

AI summary
A construction machine includes: a guidance apparatus 410 having a guidance display section 414 for displaying a target surface for an object to be worked on by a work implement 1A based on predetermined design data with respect to the object to be worked on by the work implement 1A and positional information of the work implement 1A and displaying the positional information of the work implement 1A on a guidance monitor 415 in a cabin of the construction machine; and an obstacle detecting apparatus 420 having an obstacle position acquisition section 422 for acquiring positional information of an obstacle detected around the construction machine. The guidance display section 414 of the guidance apparatus 410 displays the positional information of the obstacle acquired by the obstacle position acquisition section 422 of the obstacle detecting apparatus 420 on the guidance monitor 415. Therefore, even while the operator is keeping an eye on the screen of the guidance apparatus, it is possible to present the operator reliably with highly real-time information of the obstacle, such as an intrusive object around the machine body, making work efficiency and convenience compatible with each other.
