Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportation vehicle systems using secondary batteries face inefficiencies in charging and battery management, leading to potential electricity shortages and traffic jams due to inadequate control over battery state of charge and charging processes.
Innovation Solution
A system where transportation vehicles report their positions and remaining capacities to a ground controller, which controls charging by directing vehicles to designated charging areas with non-contact charging equipment, optimizing charging based on threshold values and vehicle placement to prevent shortages and jams, while also allowing for regenerative charging and maintenance detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If charging equipment is provided in the travel route, then charging efficiency is improved, but device complexity increases
Solution Approach 1:
The travel route is divided into charging areas and non-charging areas, with charging equipment strategically placed only in specific segments. This segmentation allows the system to provide charging functionality where needed without equipping the entire route, thereby improving charging efficiency while controlling system complexity.
Solution Approach 2:
Vehicles are controlled to travel to charging areas before their battery capacity is depleted, performing the charging action in advance. The ground controller monitors battery levels and directs vehicles to appropriate charging locations proactively, preventing electricity shortages before they occur.
2Reliability
If vehicles are controlled to travel to charging areas, then electricity shortage is prevented, but loss of time increases
Solution Approach 1:
Vehicles are directed to charging areas proactively when battery levels approach threshold values, rather than waiting for complete depletion. This preliminary action ensures reliable electricity supply by preventing shortages while allowing vehicles to complete current tasks before charging, minimizing unnecessary idle time.
Solution Approach 2:
The ground controller dynamically adjusts vehicle routing and charging schedules based on real-time battery status, task priorities, and system conditions. This dynamic control optimizes the balance between maintaining reliable electricity supply and minimizing time loss by coordinating charging with vehicle utilization needs.
3Productivity
If ground controller manages charging and vehicle allocation, then productivity is improved, but device complexity increases
Solution Approach 1:
The ground controller integrates multiple functions including battery status monitoring, charging area management, and vehicle allocation into a single centralized control system. This merging of functions improves overall system productivity by coordinating charging and vehicle deployment efficiently, while the centralized approach manages complexity by consolidating control logic in one location rather than distributing it across multiple independent systems.

AI summary
A plurality of transportation vehicles travel with power from an energy storage member along a predetermined travel route under control of a ground controller. A charging area having charging equipment for charging the energy storage member of the transportation vehicle is provided in the travel route, and the transportation vehicles report a position and remaining capacity of the energy storage member to the ground controller. The ground controller controls a transportation vehicle having remaining capacity of a threshold value or less to travel to the charging area for charging the energy storage member, and controls transportation vehicles in the charging area to travel to positions outside the charging area in accordance with transportation requests.
