Solution Overview

Problem

Conventional fee plans for vehicles do not adequately consider the residual value of batteries in electric vehicles (BEVs) and subsidies, leading to high initial fees and hesitation among users to adopt BEVs.

Innovation Solution

An information processing device and method that creates a fee plan taking into account the residual value of BEVs and available subsidies, setting an initial fixed fee for a predetermined period and reducing the fee over time after the period, with options for subsidies from national and local governments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional fee plan is used that does not consider battery residual value and subsidies, then the fee structure is simple, but the initial fee becomes excessively high causing user hesitation

Engineering Contradiction:
ImproveUser acceptance of fee planVSAvoidFee plan structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The fee plan is segmented into multiple periods: an initial period with a higher fixed fee, and subsequent periods with gradually decreasing fees. This segmentation allows the system to account for battery residual value depreciation over time while providing users with predictable, manageable payment structures that improve acceptance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fee plan transitions from a static single-fee structure to a dynamic multi-period structure where fees change over time. The fee amount is dynamically adjusted based on the passage of time and battery residual value, allowing the system to balance initial costs with long-term value while incorporating subsidy benefits.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the fee is set to reflect high initial battery value, then the fee accurately represents asset value, but user adoption of BEVs decreases

Engineering Contradiction:
ImproveFee accuracy reflecting asset valueVSAvoidBEV adoption rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent converts the harmful effect of high initial fees (which reduce adoption) into a benefit by incorporating subsidies into the fee calculation. The subsidy amount offsets the high initial battery value, effectively reducing the user's burden while maintaining accurate reflection of asset value in the underlying fee structure.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The fee structure changes its parameters over time, transitioning from a high initial fee to progressively lower fees in subsequent periods. This parameter change aligns the fee with the declining battery residual value while incorporating subsidy benefits, making the overall cost more acceptable to users without compromising the accuracy of asset value representation.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If a fixed fee is applied throughout the entire lease period, then the fee plan is simple to calculate, but it does not account for battery degradation and residual value changes

Engineering Contradiction:
ImproveFee calculation simplicityVSAvoidFee accuracy regarding battery value
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The lease period is segmented into multiple fee periods, with each period having its own fee amount. This segmentation allows the system to account for battery degradation and residual value changes at different stages of the lease term, improving measurement precision while maintaining relatively simple fixed fee calculations within each segment.

Inventive Principle:
Principle #1Segmentation

AI summary

An information processing device is an information processing device that outputs a fee plan indicating a fee required to use a vehicle or battery selected by a user, the information processing device including: an acquisition unit that acquires selection information specifying a selected object selected by the user; and a processing unit that outputs the fee plan, wherein when the selected object is eligible for a subsidy, the processing unit outputs an eligible plan as the fee plan, and in the eligible plan, the fee is set to a fixed amount of money in an initial predetermined period, and the fee is set to be lower than the fixed amount of money and to be decreased with passage of time after the predetermined period has passed.
