Solution Overview

Problem

Existing transportation systems lack an effective method to quantify and incentivize driving styles that reduce carbon footprints, leading to inefficiencies in greenhouse gas emissions.

Innovation Solution

A system and method that compares driving styles of a vehicle with similar vehicles in a geographic area to determine a carbon credit when the first set of driving styles results in a lower carbon footprint, applying this credit to the vehicle, which can be used for incentives such as reduced-cost charging or maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-generated harmful factors

If driving styles are monitored and compared to determine carbon credits, then greenhouse gas emissions are reduced, but system complexity increases

Engineering Contradiction:
Improvegreenhouse gas emissionsVSAvoidsystem complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The system uses existing telematics infrastructure to serve multiple functions: monitoring driving behavior, calculating carbon footprint, determining carbon credits, and providing incentives. This multi-functional approach reduces the need for separate dedicated systems while achieving emission reduction goals

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a carbon credit as an intermediary mechanism that translates driving behavior into tangible benefits. This intermediary simplifies the connection between monitoring systems and incentive structures, making the overall system more manageable and scalable

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If carbon footprint monitoring and comparison systems are implemented, then driving efficiency is improved, but data processing requirements increase

Engineering Contradiction:
Improvedriving efficiencyVSAvoiddata processing requirements
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The system segments data processing by comparing each vehicle's driving style against aggregated patterns from similar vehicles rather than processing all possible data combinations. This segmentation reduces computational complexity while maintaining accuracy in efficiency assessment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system processes only the essential driving parameters needed to determine carbon footprint (acceleration, braking, speed patterns) rather than analyzing all vehicle data. This partial processing approach achieves sufficient accuracy for carbon credit determination without overwhelming data processing requirements

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An example operation includes comparing a first set of driving styles for a vehicle to a second set of driving styles for one or more similar vehicles in a geographic area over a period, wherein the first set of driving styles affects a carbon footprint of the vehicle and the second set of driving styles affects another carbon footprint of the one or more similar vehicles; determining a carbon credit when the carbon footprint of the vehicle is lower than the another carbon footprint of the one or more similar vehicles, by a threshold, based on the comparing; and applying the carbon credit to the vehicle.
