Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation assistance systems for construction machines do not effectively address interference from third parties during remote operation, requiring operators to interrupt operations when interference occurs.
Innovation Solution
A remote operation assistance system that includes a distance acquisition unit, an attribute acquisition unit, an interference determination unit, and an assistance control unit to assess the likelihood of interference and control the remote operation accordingly, using a combination of distance and attribute data to assist the operator in preventing disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator remotely operates a work machine, then the operator can control the work machine from a distance, but the operator may be interfered with by third parties causing operation interruptions
Solution Approach 1:
The patent introduces an intermediary system between the operator and the work machine. This system includes detection devices that monitor the operator's surroundings and a control device that processes this information to provide assistance control. The intermediary system detects potential interference from third parties and takes preventive actions, thus protecting the operator's remote operation from interruptions while maintaining the ease of remote operation.
2Ease of operation
If the operator interrupts operation when interference occurs, then the operator can respond to third party interference, but work productivity decreases due to operation interruptions
Solution Approach 1:
The system performs preliminary actions by detecting the approach of third parties before actual interference occurs. The detection device monitors the operator's surroundings continuously, and when a potential threat is detected (such as someone approaching the operator), the system activates assistance control measures in advance. This preliminary detection and response prevents interference before it disrupts the operation, thereby maintaining productivity while ensuring operator safety.
3Reliability
If no assistance system is provided, then the system is simple, but the operator cannot be assisted in preventing interference during remote operation
Solution Approach 1:
The assistance system is segmented into distinct functional modules: a detection device that monitors the operator's surroundings, a control device that processes detection information, and an assistance control function that executes preventive actions. This segmentation allows the system to provide comprehensive interference prevention capability while maintaining a clear and manageable structure. Each module performs a specific function, making the overall system easier to understand and implement despite the added complexity of the assistance features.
