Task-Based Boarding Height Control for Worker Access Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movable body control systems lack convenience for workers performing tasks, as they do not efficiently adjust vehicle height to facilitate easy access to equipment, leading to inefficiencies and discomfort.
Innovation Solution
A movable body control device that acquires input information from a worker's terminal device to adjust the boarding part's height based on the task requirements, including starting, confirming, and completing work tasks, while considering predetermined conditions and worker preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle height is controlled to avoid contact between the passenger and vehicle roof, then safety is improved, but convenience for worker access to equipment is insufficient
Solution Approach 1:
The system performs preliminary actions by adjusting the vehicle height in advance based on the work task type before the worker needs to access equipment. The control part raises the boarding part to a height in accordance with the work task when the work task starts, and lowers it when the task is completed, proactively preparing the optimal height without waiting for manual adjustment requests.
Solution Approach 2:
The system enables self-service by automatically adjusting the vehicle height based on information from the terminal device without requiring manual intervention from the worker. The control part autonomously raises or lowers the boarding part according to the acquired work task information, allowing the system to serve itself in optimizing worker convenience.
2Productivity
If the boarding part height is manually adjusted, then worker access to equipment is improved, but time consumption and operational efficiency deteriorate
Solution Approach 1:
The system replaces manual mechanical adjustment with an automated control system. The control part uses information processing and automatic control mechanisms to adjust the boarding part height, substituting the mechanical manual operation with an intelligent automated system that responds to work task information from the terminal device.
Solution Approach 2:
The system implements feedback by continuously monitoring work task information from the terminal device and automatically adjusting the vehicle height in response. The control part receives information about work task status (started, confirmed, completed) and dynamically adjusts the boarding part height accordingly, creating a closed-loop system that adapts to worker needs in real-time.
3Adaptability or versatility
If the vehicle height is fixed, then system simplicity is maintained, but adaptability to different work tasks deteriorates
Solution Approach 1:
The system transitions from a fixed height configuration to a dynamic adjustable height system. The control part enables the boarding part to dynamically change its height based on the type of work task being performed, allowing the vehicle to adapt its configuration in real-time according to the specific requirements of different work tasks.
Solution Approach 2:
The system utilizes parameter changes by modifying the height parameter of the boarding part based on work task information. The control part changes the height parameter dynamically according to the acquired information from the terminal device, enabling the vehicle to adapt to different work scenarios through parameter adjustment rather than structural modification.

AI summary
A movable body control device controls a movable body on which a worker performing a work task at a workplace is capable of boarding and which is capable of adjusting the height of a boarding part on which the worker boards. The movable body control device includes: an acquisition part that acquires, from a terminal device that is carried by the worker and that accepts information which is input by the worker in accordance with the work task, information based on input information which is input by the worker in accordance with the work task; and a control part that controls the height of the boarding part based on the information which is acquired by the acquisition part.
