Solar Vehicle Parking Assignment for Higher Lot Power Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle management systems fail to optimize parking positions for multiple vehicles equipped with solar cells, leading to reduced overall electric power generation due to some vehicles being parked in the shade, thereby decreasing the total power output.
Innovation Solution
A vehicle management device sets parking positions based on the conversion efficiency of each vehicle's solar cell and sunlight conditions, prioritizing vehicles with high conversion efficiency to be parked in the sun for longer periods, and communicates these positions to the vehicles for user guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicles are parked randomly or without optimization in a parking lot, then the management operation is simple, but the amount of electric power generated per unit time and the sum of power generated by multiple vehicles decreases
Solution Approach 1:
The system performs preliminary calculation of sunshine time for each parking position before vehicles arrive or before parking assignment is made. By pre-calculating which positions receive sunlight during different time periods and matching these with vehicle solar cell efficiency, the system optimizes power generation without requiring complex real-time adjustments or manual intervention during operation.
Solution Approach 2:
The system changes the parameter of parking position assignment based on vehicle-specific parameters (solar cell conversion efficiency) and environmental parameters (sunshine time of each position). By dynamically matching these parameters, the system maximizes power generation output without adding physical infrastructure or complex mechanical systems.
2Loss of energy
If vehicles with high conversion efficiency are parked in the sun for longer periods, then the sum of electric power generated by multiple vehicles increases, but the complexity of managing multiple vehicles increases
Solution Approach 1:
The management system automatically performs the complex task of calculating sunshine times, ranking parking positions, and matching vehicles to positions based on their solar cell efficiency. This self-service approach eliminates the need for manual intervention or complex user decisions, allowing the system to optimize energy generation across multiple vehicles without proportionally increasing operational complexity.
Solution Approach 2:
The system uses feedback from vehicle data (conversion efficiency) and environmental data (sunshine patterns) to continuously optimize parking assignments. By establishing a feedback loop where generation results inform future assignments, the system improves total power output while the automated nature of the feedback processing keeps management complexity manageable.
3Productivity
If parking positions are assigned without considering sunlight conditions, then the parking management is simple, but the conversion efficiency of solar cells is not maximized
Solution Approach 1:
The system performs preliminary calculation of sunshine time for each parking position before vehicles arrive or before parking assignment is made. By pre-calculating which positions receive sunlight during different time periods and matching these with vehicle solar cell efficiency, the system optimizes power generation without requiring complex real-time adjustments or manual intervention during operation.
Solution Approach 2:
The system changes the parameter of parking position assignment based on vehicle-specific parameters (solar cell conversion efficiency) and environmental parameters (sunshine time of each position). By dynamically matching these parameters, the system maximizes power generation output without adding physical infrastructure or complex mechanical systems.
