Remote Operation Terminal Primary Setting Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles with multiple remote operation terminals face challenges in preventing mistakes and confusion during primary setting changes, especially when multiple operators are involved.
Innovation Solution
An operation system for a work vehicle that includes a work apparatus, a control apparatus, remote operation terminals, and an information relay device. The system allows only one selected remote operation terminal to change the primary setting, and reflects this change across all terminals, ensuring synchronized settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple remote operation terminals are provided to operate the work apparatus, then the ease of operation is improved, but mistakes and confusion in primary setting may occur
Solution Approach 1:
The patent applies local quality by giving different functional permissions to different remote operation terminals. Specifically, one terminal is designated with authority to change primary settings while other terminals are restricted from making such changes. This differentiation in permission levels among terminals resolves the contradiction by maintaining ease of operation through multiple terminals while ensuring reliability through controlled access to critical settings.
Solution Approach 2:
The patent implements feedback mechanisms where the control apparatus notifies remote operation terminals about the current state of primary settings and any changes made. When a setting is changed by one terminal, this information is feedback to other terminals, ensuring they are aware of the current configuration. This feedback loop prevents confusion and mistakes by keeping all operators informed of the system state.
2Ease of operation
If primary setting can be changed by any remote operation terminal, then the ease of operation is improved, but mistakes and confusion in primary setting increase
Solution Approach 1:
The patent applies local quality by giving different functional permissions to different remote operation terminals. Specifically, one terminal is designated with authority to change primary settings while other terminals are restricted from making such changes. This differentiation in permission levels among terminals resolves the contradiction by maintaining ease of operation through multiple terminals while ensuring reliability through controlled access to critical settings.
3Reliability
If only one remote operation terminal is designated to change primary setting, then mistakes and confusion are prevented, but the ease of operation is reduced
Solution Approach 1:
The patent applies universality by enabling multiple remote operation terminals to perform operational functions while designating specific permissions for primary setting changes. All terminals can operate the work apparatus, but only the designated terminal can modify primary settings. This multi-functional approach resolves the contradiction by allowing broad operational access (ease of operation) while maintaining controlled access to critical settings (reliability).

AI summary
The invention addresses the problem of providing a work vehicle that can prevent mistakes and confusion in primary settings even when a plurality of operators each operate a remote operation terminal. This work vehicle (crane 1) comprises a work device 40 that is operable using a remote operation terminal 13, wherein a primary setting of the work device 40 can be changed with the remote operation terminal 13 and when one of the plurality of remote operation terminals 13 changes a primary setting, the change is reflected in the other remote operation terminals 13.
