Shovel Notification System for Selective Object Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shovel technologies often disrupt work efficiency by providing unnecessary notifications when a monitoring object is detected, leading to interruptions in work operations at a worksite.
Innovation Solution
A shovel management system equipped with a detecting part and a notification part that determines the necessity of providing notifications to the surroundings, using a combination of image capturing devices and surrounding information obtaining devices to detect objects and assess the need for alerts, thereby minimizing interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shovel provides a notification whenever a monitoring object is detected, then safety awareness is improved, but work efficiency deteriorates due to unnecessary interruptions
Solution Approach 1:
The notification system changes the parameter of notification frequency based on the type of monitoring object detected. When a worker is detected, no notification is provided (maintaining work efficiency). When another vehicle is detected, a notification is provided (enhancing safety awareness). This selective parameter change resolves the contradiction between safety and efficiency.
Solution Approach 2:
Different notification behaviors are applied to different types of monitoring objects. The system treats workers and other vehicles differently in terms of notification provision. This local differentiation allows the system to maintain work efficiency for worker detection while ensuring safety awareness for vehicle detection, thus resolving the contradiction.
2Reliability
If the shovel provides frequent notifications to ensure safety, then safety awareness is improved, but work interruptions increase
Solution Approach 1:
The system changes the notification parameter from frequent/continuous to selective/conditional based on the detected object type. Notifications are only triggered when other vehicles are detected, not when workers are detected. This parameter change reduces work interruptions while maintaining necessary safety awareness.
3Measurement precision
If the shovel uses multiple detection methods to improve accuracy, then detection precision is improved, but device complexity increases
Solution Approach 1:
The image recognition model acts as an intermediary that processes data from multiple image capturing devices and automatically identifies the type of monitoring object. This intermediary consolidates the complexity of multiple detection methods into a single processing step, improving detection precision without significantly increasing overall system complexity.

AI summary
A shovel includes a lower traveling body; an upper turning body turnably mounted on the lower traveling body; a work attachment attached to the upper turning body; a detecting part provided to the upper turning body and configured to detect a predetermined object around the shovel; and a notification part configured to provide a notification to surroundings of the shovel in response to detection of the predetermined object by the detecting part. The notification part determines whether to provide the notification to the surroundings of the shovel in response to the detection of the predetermined object by the detecting part.
