Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional electric vehicles use traditional brake and clutch systems, then braking function is achieved, but energy is lost during braking

Engineering Contradiction:

Improveenergy loss during brakingVSAvoidbraking operation

Core Design Contradiction:

Loss of energyVSEase of operation

Solution Approach 1:

The patent combines the brake pedal and clutch pedal into a single integrated pedal assembly. When the driver presses the pedal, it simultaneously engages both the electric brake system and the electric clutch system, merging two separate control functions into one operational interface. This eliminates the need for separate brake and clutch pedals while achieving both functions simultaneously.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent converts the energy that would normally be lost during braking into useful electrical energy. The electric brake system captures kinetic energy during deceleration and converts it to electrical energy through electromagnetic induction, which is then stored in the battery. This transforms the harmful energy loss into a beneficial charging opportunity.

Inventive Principle:

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

2Power

If hybrid vehicles use fuel-based power systems, then power production is achieved, but carbon emissions are generated

Engineering Contradiction:

Improvepower productionVSAvoidcarbon emissions

Core Design Contradiction:

PowerVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the traditional internal combustion engine with an electric motor system. Instead of using fuel combustion to generate mechanical power, the system uses electrical energy stored in the battery to drive electric motors that power the vehicle. This substitution eliminates carbon emissions while maintaining power production capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental energy source parameter from chemical energy (fuel) to electrical energy. By switching from a fuel-based power system to an electric power system, the vehicle achieves zero carbon emissions while maintaining the ability to produce sufficient power for operation.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If automatic transmission remains connected to engine during braking, then transmission function is maintained, but energy loss occurs

Engineering Contradiction:

Improvetransmission connectionVSAvoidenergy loss during braking

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent introduces dynamic control of the connection between the automatic transmission and the power system through an electric clutch. Instead of a permanent mechanical connection, the system uses an electrically controlled clutch that can engage or disengage the transmission from the drive system based on operating conditions. During braking, the clutch disengages to prevent energy loss, while maintaining transmission functionality when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces an electric clutch as an intermediary component between the automatic transmission and the drive system. This intermediary device allows controlled disconnection of the transmission during braking events, preventing direct mechanical energy loss while maintaining the ability to reconnect when power transmission is required. The electric clutch acts as a smart mediator that optimizes energy efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)
