Multipurpose Vehicle Door Coordination for Mobility Device Boarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation systems using multipurpose vehicles face challenges in managing the opening/closing of loading and boarding spaces, and controlling vehicle movement, especially when passengers with small mobility devices are involved.
Innovation Solution
A transportation system and method that utilize a control unit to coordinate the opening/closing of loading spaces, boarding spaces, and vehicle driving, ensuring that these actions interwork when a passenger with a small mobility device is on board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate control of loading space and boarding space is implemented, then flexibility in space management is improved, but control complexity increases
Solution Approach 1:
The patent combines the control of loading space door and boarding space door into a single integrated control system. The control unit receives one request signal and automatically executes the coordinated sequence of opening/closing both doors, eliminating the need for separate manual control operations while maintaining flexible space management capabilities.
Solution Approach 2:
The control system automatically determines the operation sequence and executes door operations without requiring manual intervention for each individual door. The system self-manages the coordination between loading space and boarding space doors based on the single received request, reducing control complexity while preserving adaptability.
2Productivity
If manual control of door operations is used, then system simplicity is maintained, but operational efficiency decreases
Solution Approach 1:
The control unit automatically executes the complete sequence of door operations based on a single request signal, eliminating the need for manual control of each door operation. This automation significantly improves operational efficiency by reducing the time and steps required for loading and boarding operations.
Solution Approach 2:
The control system is pre-programmed with the correct sequence of door operations. When a request is received, the system automatically executes the predetermined sequence of opening loading space door, opening boarding space door, closing boarding space door, and closing loading space door, improving operational efficiency without adding complex real-time decision-making requirements.
3Adaptability or versatility
If loading space and boarding space are controlled independently, then operational flexibility is improved, but coordination difficulty increases
Solution Approach 1:
The patent merges the control functions of loading space door and boarding space door into a single integrated control unit. This unified control approach maintains operational flexibility by responding to various request scenarios while automatically handling the coordination complexity internally, eliminating the need for complex inter-door coordination management.

AI summary
A transportation system includes a multipurpose vehicle in which a loading space for a mobility device and a boarding space for passengers are provided; and a control unit configured to control opening or closing of the loading space, opening or closing of the boarding space, and driving of the vehicle so that, when there is a passenger who possesses or utilizes the mobility device among passengers, opening or closing of the loading space, opening or closing of the boarding space, and driving of the vehicle interwork with each other.
