Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing noncontact power supply systems face issues where vehicles concentrate at specific ground power supply apparatuses, leading to insufficient power supply and high capital investment for capacity increases.
Innovation Solution
A system that includes a server setting charges for ground power supply apparatus usage based on electric power demand, communicated through an information device to users, and a control device for automated driving, dispersing vehicle distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ground power supply apparatuses are installed to provide noncontact power supply to vehicles, then vehicles can receive power supply, but vehicles tend to concentrate at specific apparatuses causing insufficient power supply and requiring enormous capital investment to increase capacity
Solution Approach 1:
The server collects information on the number of vehicles at each ground power supply apparatus and uses this feedback to dynamically adjust charges. When an apparatus becomes congested with many vehicles, the charge increases, providing feedback to guide vehicles to less congested apparatuses, thus balancing the distribution and ensuring sufficient power supply without needing to install excessive apparatuses
Solution Approach 2:
The system changes the charge parameter dynamically based on the number of vehicles at each ground power supply apparatus. By adjusting this economic parameter in response to vehicle concentration, the system optimizes the distribution of vehicles across apparatuses, maintaining reliable power supply while minimizing the total number of apparatuses required
2Reliability
If the number of ground power supply apparatuses is increased to handle concentrated vehicle demand, then power supply capacity is sufficient, but enormous capital investment becomes necessary
Solution Approach 1:
The server continuously monitors vehicle concentration at each apparatus and adjusts charges accordingly, providing real-time feedback that prevents overwhelming any single apparatus. This feedback mechanism ensures that existing apparatuses operate within their capacity limits, maintaining reliable power supply without requiring excessive system expansion
Solution Approach 2:
By dynamically changing the charge parameter based on vehicle distribution, the system optimizes the utilization of existing ground power supply apparatuses. This parameter adjustment ensures adequate power supply capacity is maintained while avoiding the need to substantially increase the overall system scale
