Work Machine Selection Using Usage History to Level Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of work machines, such as lawn mowers and snow blowers, is hindered by uneven usage patterns, leading to disparate maintenance and replacement timing across similar machines, increasing administrative burdens.
Innovation Solution
A selection support device that acquires history information on the usage of work machines, specifies their degree of use, and preferentially selects machines with lower usage for work assignments, thereby leveling their usage and synchronizing maintenance and replacement schedules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If work machines are selected without considering usage history, then selection process is simple, but maintenance and replacement timing become disparate increasing management burden
Solution Approach 1:
The system implements feedback by continuously monitoring the usage history of work machines and using this information to inform future selection decisions. The selection support device queries usage history from storage, calculates degree of use metrics, and feeds this back into the selection process to automatically balance usage across machines, thereby reducing management burden without complicating the selection operation.
2Device complexity
If work machines are selected based on usage history to level usage, then maintenance timing is synchronized, but selection process becomes more complex
Solution Approach 1:
The selection support device performs self-service by automatically querying usage history, calculating degree of use, and determining optimal machine selections without requiring manual intervention. The system autonomously balances usage across work machines by preferentially selecting machines with lower degree of use, thereby synchronizing maintenance timing while keeping the selection process simple for users.
3Productivity
If usage history is tracked for all work machines, then usage leveling is achieved, but data management complexity increases
Solution Approach 1:
The selection support device serves multiple functions: it queries usage history, calculates degree of use metrics, determines optimal machine selections, and provides selection results all through a single integrated system. This multi-functionality achieves usage leveling and synchronized maintenance scheduling without requiring separate complex data management systems, thereby improving resource management efficiency while maintaining system simplicity.
