Work Machine Restraint Control With Switchable Detection Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work machines with object detection functions activate a buzzer when an object is detected, which can be bothersome to the operator.
Innovation Solution
Implement a method for controlling the work machine that includes a restraint process based on detection results, switching between enabled and disabled states of the restraint function, and displaying restraint state information on a display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buzzer is activated when an object is detected, then the operator is informed of the detection, but the operator is bothered by continuous alerts
Solution Approach 1:
The restraint function is made dynamically switchable between enabled and disabled states through a switch processor, allowing the operator to adjust the system's behavior based on operational needs. This dynamic control resolves the contradiction by enabling the operator to disable bothersome alerts while maintaining the detection function's reliability when needed.
Solution Approach 2:
The system changes the operational parameter of the restraint function from fixed to variable, allowing transition between different states (enabled/disabled). This parameter change enables the operator to balance between receiving necessary alerts and avoiding bothersome notifications, thus resolving the contradiction between reliability and ease of operation.
2Reliability
If the restraint function is always enabled, then safety is improved, but the operator experiences cumbersome operation
Solution Approach 1:
The restraint function transitions from a static always-enabled state to a dynamic switchable state, allowing the operator to enable it only when safety restraint is needed. This resolves the contradiction by providing operational safety when required while avoiding cumbersome operation during normal use.
Solution Approach 2:
The system provides preliminary information to the operator through display of restraint state information, enabling informed decisions about when to enable or disable the restraint function. This preliminary information delivery allows the operator to proactively manage the restraint function based on situational needs, balancing safety and convenience.
3Loss of information
If the restraint state information is displayed, then the operator is informed of the function status, but the display complexity increases
Solution Approach 1:
The system displays only the essential restraint state information (enabled/disabled status) rather than comprehensive system details. This partial information display resolves the contradiction by providing sufficient status information to the operator while avoiding excessive display complexity.

AI summary
[Problem] A method for controlling a work machine, a work machine control program, a work machine control system, and a work machine that are less cumbersome for the operator are provided. [Solution] The method for controlling the work machine includes executing a restraint process of restraining an operation of the work machine based on a detection result of a detector detecting a detection target in a monitoring area around the work machine, performing switching between an enabled state and a disabled state of a function associated with the restraint process, and displaying a display screen Dpi including restraint state information I1 indicating whether the function associated with the restraint process is enabled or disabled, on a display device.
