Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If charging stations use wired connections for power delivery, then power transfer reliability is improved, but communication intelligence and additional functionality are limited

Engineering Contradiction:

Improvepower transfer reliabilityVSAvoidcommunication intelligence

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The charging station is designed to perform multiple functions: it can both deliver power wirelessly to vehicles and receive power from vehicles, in addition to communicating with vehicles about energy needs. This multi-functionality resolves the contradiction by enabling intelligent communication and energy management while maintaining reliable power transfer capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Device complexity

If charging stations communicate only through wired connections, then communication simplicity is maintained, but additional roles and functions cannot be performed

Engineering Contradiction:

Improvecommunication simplicityVSAvoidadditional roles

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent replaces wired mechanical connections with wireless communication systems. The charging station uses wireless signals to communicate with vehicles about energy needs and coordinates energy transfer, eliminating the need for physical communication connections while enabling more sophisticated information exchange and additional functional roles.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If charging stations wait for vehicle connection to assess energy needs, then system simplicity is maintained, but queue times and energy distribution efficiency are increased

Engineering Contradiction:

Improvesystem simplicityVSAvoidqueue times

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The charging station performs preliminary actions by wirelessly communicating with vehicles before they physically connect to assess their energy needs. This advance assessment allows the station to prepare energy distribution plans and optimize charging schedules, reducing queue times and improving overall system efficiency without significantly increasing complexity.

Inventive Principle:

Principle #10Preliminary action

4Device complexity

If charging stations lack wireless communication capabilities, then device complexity is reduced, but energy management intelligence and optimization are limited

Engineering Contradiction:

Improvedevice complexityVSAvoidenergy management efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The charging station implements feedback mechanisms through wireless communication, receiving information from vehicles about their energy needs, battery status, and charging requirements. This feedback enables the station to intelligently manage energy distribution, optimize charging schedules, and improve overall productivity while maintaining manageable system complexity.

Inventive Principle:

Principle #23Feedback
