Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In noncontact power supply systems, accurately calculating the utilization fee is challenging due to mismatches between the amount of electric power transmitted and received, and the difficulty in obtaining an accurate grasp of the utilized power.
Innovation Solution
A noncontact power supply system comprising a mobile unit, a ground power supply apparatus, and a server that communicates with both units to calculate the utilization fee based on the number of times the ground power supply apparatus is utilized, rather than the exact amount of electric power used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the fee is calculated based on the amount of electric power transmitted or received, then the billing can reflect power usage, but it becomes difficult to accurately grasp the actual amount of electric power utilized due to transmission losses and efficiency variations
Solution Approach 1:
The patent introduces a server as an intermediary that receives utilization information from both the ground power supply apparatus and the mobile unit, processes this data, and calculates the fee. This mediator consolidates information from multiple sources without requiring direct complex measurement verification between transmitting and receiving ends, resolving the measurement accuracy problem while maintaining system simplicity.
2Reliability
If the fee calculation system attempts to measure and verify the exact amount of electric power received by the mobile unit, then accurate billing can be achieved, but the system complexity and difficulty of verification increase significantly
Solution Approach 1:
The patent segments the fee calculation process into multiple independent components: the ground power supply apparatus records transmission information, the mobile unit records reception information, and the server synthesizes these segmented data pieces to determine final utilization. This segmentation allows each component to perform simple, reliable functions independently while achieving overall calculation reliability through data consolidation.
Solution Approach 2:
The system implements feedback mechanisms where both the ground power supply apparatus and the mobile unit transmit their respective measurement data to the server. This dual-side feedback provides corroborating information that enhances the reliability of fee calculation without requiring any single component to perform complex verification, thereby reducing measurement difficulty while improving reliability.
3Ease of operation
If the system uses simple utilization metrics like number of times of utilization, then fee calculation becomes straightforward, but it may not accurately reflect the actual energy consumption variations
Solution Approach 1:
The server performs multiple functions: it receives transmission data from the ground power supply apparatus, receives reception data from the mobile unit, verifies consistency between these data sets, and calculates fees based on synthesized utilization information. This multi-functional approach allows the system to maintain simple operation while achieving precise energy consumption measurement through data cross-verification and comprehensive analysis.
