Working Machine Mode Switching for On-Demand Diagnostics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diagnosing working machines, such as lawn mowers, often requires interrupting their operation, which is labor-intensive, time-consuming, and costly, leading to inefficiencies and unscheduled work interruptions.
Innovation Solution
A working machine equipped with a control unit that operates in a first mode without diagnostic data collection, switching to a second mode for data collection upon receiving a diagnosis instruction, allowing continuous operation while gathering diagnostic data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the working machine operates in normal mode without diagnostic data collection, then work efficiency is maintained, but diagnostic capability is lost requiring work interruption
Solution Approach 1:
The system dynamically switches between first work mode (normal operation without diagnostic collection) and second work mode (data collection mode) based on received instructions. This dynamic mode switching allows the machine to maintain high productivity during normal operation while enabling diagnostic capability when needed, resolving the contradiction between work efficiency and diagnostic capability.
2Reliability
If diagnostic data is collected during work, then diagnostic capability is improved, but work efficiency decreases due to data processing overhead
Solution Approach 1:
Instead of continuously collecting diagnostic data, the system periodically switches to data collection mode based on received instructions. This periodic action allows diagnostic capability to be activated only when needed, minimizing the impact on work efficiency while ensuring diagnostic data can be collected when required.
Solution Approach 2:
The system changes operational parameters by switching between different work modes. In the first mode, diagnostic data collection is disabled to maximize work efficiency. In the second mode, data collection is enabled when diagnostic capability is needed. This parameter change approach allows the system to optimize for either productivity or diagnostic capability based on operational requirements.
3Measurement precision
If the working machine interrupts work for diagnosis, then diagnostic accuracy is improved, but time loss increases
Solution Approach 1:
The system enables continuous work operation while diagnostic data is being collected in the second work mode. This continuity of useful action eliminates the need to interrupt work for diagnosis, thereby maintaining diagnostic accuracy without incurring time loss from work interruptions. The machine can simultaneously perform work and collect necessary diagnostic information.

AI summary
A working machine comprising: a control unit configured to cause the working machine to perform work in a first work mode in which work is performed without collecting diagnostic data; an acceptance unit configured to accept a diagnosis instruction; and a switching unit configured to switch from the first work mode to a second work mode in which work is performed while collecting the diagnostic data, in a case where the diagnosis instruction is accepted by the acceptance unit, wherein the control unit causes the working machine to perform work in the second work mode in a case where the switching unit switches to the second work mode.
