Work Machine Activation Control Using Precaution Confirmation History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work machines find it bothersome to repeatedly see safety precaution displays each time the machine is activated, despite having already confirmed the precautions.
Innovation Solution
An activation system for work machines that includes a communication unit to receive confirmation history information from a server, a presentation unit to present precautions, and a determination unit to decide whether to display precautions based on this history, allowing operators who have confirmed precautions to omit unnecessary displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the work machine displays safety precautions each time it is activated, then the operator is reminded of safety measures, but the operator experiences repetitive notifications that are bothersome
Solution Approach 1:
The system performs preliminary action by storing confirmation history information in advance in a server device. When the work machine is activated, the determination unit checks this pre-stored information to identify operators who have already confirmed precautions, thereby avoiding redundant displays and improving operator convenience while maintaining safety reminders for those who need them.
Solution Approach 2:
The system implements feedback by using confirmation history information to determine whether to display precautions. The communication unit receives feedback from the server device about which operators have confirmed precautions, and this feedback is used to adjust the display behavior, creating a closed-loop system that balances safety reminders with operator convenience.
2Reliability
If the work machine displays safety precautions every activation, then safety awareness is maintained, but time is lost due to repetitive displays
Solution Approach 1:
The confirmation history information is prepared in advance in the server device, allowing the work machine to quickly determine during activation whether precautions need to be displayed. This preliminary preparation reduces the time lost during each activation by avoiding unnecessary display and confirmation steps for operators who have already been instructed.
Solution Approach 2:
The system uses feedback from confirmation history to optimize activation time. By receiving information about which operators have previously confirmed precautions, the system can skip redundant display steps, thereby reducing the time required for machine activation while maintaining safety awareness through targeted reminders.

AI summary
An activation system for a work machine includes a communication unit, a presentation unit, and a determination unit. The work machine includes a power source and an additional function unit that realizes a predetermined additional function. The communication unit receives confirmation history information indicating an operator who has confirmed a precaution related to the predetermined additional function from a server device. The a presentation unit presents the precaution. The determination unit determines whether or not to omit presentation of the precaution based on the confirmation history information.
