Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single imaging device with a narrow angle of view is used to monitor working equipment, then defect detection precision is improved, but the ability to detect ground hazards like boulders deteriorates
Solution Approach 1:
The monitoring system is segmented into two distinct imaging devices: a first imaging device with a narrow angle of view dedicated to monitoring working equipment for defect detection, and a second imaging device with a wide angle of view dedicated to monitoring the ground for hazard detection. This segmentation allows each device to optimize its performance for its specific monitoring task, resolving the contradiction between precision and versatility.
2Adaptability or versatility
If a single imaging device with a wide angle of view is used to monitor ground, then ground hazard detection capability is improved, but defect detection precision deteriorates
Solution Approach 1:
The system divides monitoring functions between two specialized imaging devices. The second imaging device with a wide angle of view is dedicated to ground monitoring, providing comprehensive hazard detection capability. The first imaging device with a narrow angle of view is dedicated to working equipment monitoring, providing high precision defect detection. This functional segmentation resolves the contradiction.
3Adaptability or versatility
If multiple imaging devices with different angles of view are used, then both defect detection precision and ground hazard detection capability are improved, but device complexity increases
Solution Approach 1:
The control device serves multiple functions: it controls both the first imaging device for working equipment monitoring and the second imaging device for ground monitoring. It also performs image processing, defect determination, and hazard determination functions. This multi-functionality consolidates the system's complexity into a single control unit, making the addition of multiple imaging devices more manageable.
4Reliability
If real-time monitoring of working equipment is implemented, then damage prevention capability is improved, but system complexity increases
Solution Approach 1:
The system replaces manual inspection methods with automated imaging and image processing. The control device automatically captures images, processes them, determines defects, and provides alerts, eliminating the need for manual monitoring. This substitution reduces operational complexity while enhancing reliability through continuous automated surveillance.

AI summary
A work machine monitoring system includes a first imaging device that is provided in a work machine and has a first angle of view to image working equipment included in the work machine, a second imaging device that is provided in the work machine and has a second angle of view wider than the first angle of view to image a ground on which the work machine travels, a defect determination unit that determines presence or absence of a defect in the working equipment based on image data captured by the first imaging device, and a boulder determination unit that determines presence or absence of a boulder on the ground based on image data captured by the second imaging device.
