Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a single battery is used in electric vehicles, then the vehicle structure is simple, but the vehicle must stop frequently for recharging

Engineering Contradiction:

Improveoperation durationVSAvoidbattery system complexity

Core Design Contradiction:

Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The battery system is divided into multiple independent batteries (first battery, second battery, third battery) that can be independently charged and discharged. The power discharging controller selectively activates different batteries based on charge levels, enabling continuous operation without frequent stops while maintaining manageable system complexity through modular architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system implements a battery rotation strategy where discharged batteries are automatically recharged by the dynamo and solar panel while other batteries continue to power the vehicle. This ensures that at least one battery is always available for operation, eliminating the need to stop for recharging while the vehicle is in motion.

Inventive Principle:

Principle #34Discarding and recovering

2Use of energy by moving object

If the vehicle stops to recharge, then the battery can be fully recharged, but the vehicle operation is interrupted

Engineering Contradiction:

Improveenergy replenishmentVSAvoidrecharge downtime

Core Design Contradiction:

Use of energy by moving objectVSLoss of time

Solution Approach 1:

The dynamo is driven by the vehicle's motion to continuously recharge batteries during operation. Simultaneously, the solar panel provides continuous charging when the vehicle is stationary. This dual charging approach ensures uninterrupted energy replenishment, eliminating recharge downtime while maintaining continuous vehicle operation.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The vehicle's own motion drives the dynamo to recharge its batteries, making the system self-sufficient. The solar panel supplements this by charging batteries during stationary periods. This self-service capability eliminates dependency on external charging infrastructure and prevents operational interruptions.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If traditional charging systems are used, then the system is simple, but environmental energy sources like wind and sunlight are not utilized

Engineering Contradiction:

Improveenergy source adaptabilityVSAvoidcharging system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The charging system integrates multiple energy sources: the dynamo converts mechanical energy from vehicle motion into electrical energy, while the solar panel converts sunlight into electrical energy. Both charge the battery system, creating a universal charging solution that adapts to different operating conditions (motion vs. stationary) without significantly increasing system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A system and method for an alternative power system that uses a dynamo with a centrifugal fan and solar panel connected in parallel to recharge multiple batteries simultaneously. As the vehicle operates on the Alternative Power System, the power discharging controller utilizes battery A. In parallel, the dynamo with a centrifugal fan and a solar panel recharge battery B and battery C. A charging controller manages this recharging functionality. When battery A, which supplies power to motor, is reduced to a certain level, a power discharging controller automatically switches to battery B, and the charging controller connects automatically to battery A and recharges battery C and battery A. When battery B is reduced to a certain level, the power discharging controller switches to battery C. Then, charging controller connects automatically to battery B and recharges battery A and battery B.
