Solution Overview

Problem

Existing technologies do not adequately consider the method of generating power stored in a vehicle's battery, limiting the effectiveness of using information related to vehicle charging.

Innovation Solution

A control apparatus that acquires energy information indicating the method of generating power stored in a vehicle's battery, determines a usage fee based on this information, and notifies the user of the fee.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If traditional charging information recording methods are used, then charging data can be stored, but the method of generating power is not considered and user awareness of energy resources is insufficient

Engineering Contradiction:
Improveenergy generation method informationVSAvoiduser awareness of energy resources
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The charging information is segmented into multiple dimensions: not only recording that charging occurred, but also categorizing the energy generation method (renewable vs. non-renewable). This segmentation allows the system to preserve detailed energy source information while presenting it in a simplified binary classification that enhances user comprehension and awareness.

Inventive Principle:
Principle #1Segmentation

2Productivity

If usage fee is determined without considering energy generation method, then pricing is simple, but energy resource promotion and user awareness are limited

Engineering Contradiction:
Improveeffectiveness of charging information utilizationVSAvoidfee determination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The fee determination system changes the parameter of energy generation method from an ignored factor to a decisive pricing parameter. By introducing renewable energy identification as a new parameter, the system enables differentiated pricing strategies that promote renewable energy usage while maintaining relatively simple implementation through binary classification and corresponding fee structures.

Inventive Principle:
Principle #35Parameter changes
