Problem

Existing transportation systems lack efficient methods for managing energy transfer between vehicles and locations based on intended use, particularly in scenarios where power disruptions occur, and there is a need for decentralized and secure authorization of vehicle services and energy sharing.

Innovation Solution

A system that utilizes blockchain technology for secure, decentralized authorization of vehicle services and energy transfer between vehicles and locations, using smart contracts to manage energy distribution based on intended use and environmental factors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If energy transfer between vehicles and locations is implemented without decentralized authorization, then energy distribution can be centralized and controlled, but security and reliability of energy transfer are compromised

Engineering Contradiction:
Improvesecurity of energy transferVSAvoidsystem architecture complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A blockchain-based intermediary layer is introduced between energy providers and consumers to enable secure, decentralized authorization. The blockchain network acts as a trusted mediator that validates energy transfer requests through smart contracts, eliminating the need for centralized authorization while maintaining security and reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional centralized energy management is used, then control and monitoring are simplified, but adaptability to different energy needs and environmental conditions is reduced

Engineering Contradiction:
Improveadaptability to energy needsVSAvoidauthorization system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system employs dynamic smart contracts that can adapt to varying energy needs and environmental conditions. These contracts automatically adjust energy transfer parameters based on real-time data from sensors and network participants, enabling the system to respond flexibly to changing conditions without requiring complex manual authorization processes.

Inventive Principle:
Principle #15Dynamics

3Loss of energy

If energy transfer is initiated without considering intended use, then energy distribution is simplified, but energy efficiency and optimization are reduced

Engineering Contradiction:
Improveenergy efficiencyVSAvoidenergy management complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The system incorporates feedback mechanisms where information about intended use, environmental conditions, and energy consumption patterns is continuously collected and fed back into the smart contracts. This enables the system to optimize energy transfer decisions by considering the actual needs and conditions at the receiving location, thereby improving energy efficiency without excessive complexity.

Inventive Principle:
Principle #23Feedback

AI summary

An example operation includes one or more of establishing communication between a transport and a location via a module including a battery, determining an energy amount in the transport and an energy requirement at the location, and initiating a transfer of a portion of the energy amount from the transport to the battery based on an intended use of the portion at one or more devices at the location.
