Industrial Vehicle Detection Modes for Seat-Based Alarm Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial vehicle detection systems require two people to confirm the collaboration between detection and notification devices, which is inconvenient as the driver must leave the driver's seat for inspection.
Innovation Solution
An industrial vehicle with a first mode that detects the surrounding region excluding the driver's seat and a second mode that includes the driver's seat, allowing the driver to confirm device collaboration from the seat using a mode selection part, condition determination, and separate camera processing for the driver's seat detection.

Engineering Contradiction Analysis
1Reliability
If the driver leaves the driver's seat to be detected by the detection device for inspection, then the collaboration between detection device and notification device can be confirmed, but the inspection process becomes inconvenient and time-consuming
Solution Approach 1:
The detection range is segmented into two distinct zones: a first detection range that excludes the driver's seat area and a second detection range that includes the driver's seat. This segmentation allows the system to perform different detection functions in different spatial zones, enabling the driver to remain seated during inspection while the detection device monitors the surrounding region for collaboration verification.
Solution Approach 2:
The system dynamically switches between two operational modes: a first mode where the driver's seat is excluded from the detection range, and a second mode where the driver's seat is included. This dynamic reconfiguration of the detection range allows flexible inspection procedures without requiring the driver to physically leave the seat, thereby improving inspection convenience while maintaining reliability.
2Reliability
If the driver's seat is included in the detection range, then the detection device can detect the driver for inspection purposes, but false alarms may occur during normal operation
Solution Approach 1:
The detection range is divided into a first detection range (excluding driver's seat) for normal operation and a second detection range (including driver's seat) for inspection mode. This spatial segmentation ensures that during normal operation, the driver's seat is not monitored, preventing false alarms caused by the driver's presence, while still allowing accurate detection of persons in the surrounding region.
Solution Approach 2:
The system dynamically adjusts the detection range based on operational mode. In the first mode (normal operation), the driver's seat is excluded from detection to prevent false alarms. In the second mode (inspection), the driver's seat is included to enable detection of the driver for collaboration verification. This dynamic adjustment eliminates false alarms during normal operation while maintaining detection accuracy during inspection.

AI summary
An industrial vehicle has a first mode and a second mode. The industrial vehicle includes: a detection device configured to detect a person and/or an object in a surrounding region of the industrial vehicle and a person in a driver's seat as a detection target; a notification device configured to output an alarm by light and/or sound; a notification control part that causes the notification device to output the alarm upon detection of the detection target by the detection device; and a mode selection part operated to cause the industrial vehicle to transition to the first mode and the second mode. The detection device includes a range setting part that sets the surrounding region as a detection range to detect the detection target without setting the driver's seat as the detection range in the first mode, and sets the driver's seat as the detection range in the second mode.
