Work Machine Mode Tracking for Failure-Prone Operation Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for remotely monitoring work machines with multiple operating modes fail to provide detailed information on which mode is prone to failures, making it difficult to quickly address issues.
Innovation Solution
A management apparatus that receives work information and mode change information from work machines, stores this data, and specifies failures based on associated information to recommend suitable work modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the server only receives various kinds of information without considering work modes, then the system structure remains simple, but detailed information such as work mode in which failure occurs cannot be obtained
Solution Approach 1:
The patent segments work information by work modes, creating separate storage areas for each mode. The storage unit divides information into first work information (first mode) and second work information (second mode), allowing detailed analysis per mode without overwhelming complexity in a single unified structure.
Solution Approach 2:
The patent adds a dimensional layer by introducing work mode as a classification dimension. Instead of storing work information flatly, it organizes information along the dimension of work modes, enabling the specifying unit to identify failure-prone modes by comparing across this new dimension.
2Measurement precision
If work information is stored without association with work modes, then storage structure remains simple, but failure analysis precision deteriorates
Solution Approach 1:
The storage unit segments work information by associating it with specific work modes. First work information is linked to the first work mode and second work information to the second work mode, creating mode-specific data segments that enable precise failure analysis for each operational context.
Solution Approach 2:
The patent applies local quality by tailoring the information storage and analysis approach to each work mode. Each mode receives customized attention with its own information set, allowing the specifying unit to apply mode-specific criteria for identifying failure patterns rather than using a generic analysis approach.
3Reliability
If the system does not distinguish work modes, then operation simplicity is maintained, but the ability to identify failure-prone modes is lost
Solution Approach 1:
The patent performs preliminary action by pre-organizing work information according to work modes before failure analysis is needed. The storage unit establishes mode-based categorization in advance, so when failure occurs, the specifying unit can immediately query the relevant mode's information without needing to reorganize or filter data during the analysis process.
Solution Approach 2:
The specifying unit provides feedback by identifying and reporting failure-prone work modes based on the stored mode-associated information. This feedback mechanism enables operators to adjust operations away from problematic modes, improving reliability while maintaining simple interaction through automated analysis.

AI summary
A management apparatus for managing a work machine capable of operating in a plurality of work modes, comprising: a work information reception unit configured to receive work information of the work machine; a change information reception unit configured to receive, if a work mode of the work machine is changed, work mode change information from the work machine; a storage unit configured to store the work information and the work mode in association with each other; and a specifying unit configured to specify a failure based on information stored in the storage unit.
