Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If additional alternators are added to the vehicle to extend battery life, then energy generation is improved, but device complexity increases

Engineering Contradiction:
Improvebattery lifeVSAvoidalternator system complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The alternator system is divided into modular components: magnetic connectors attached to wheel rims, magnetic bars connected to rotators, and stators with electrical connections to the battery. This segmentation allows multiple alternators to be distributed across different wheels, extending battery life through cumulative energy generation while maintaining manageable system complexity through standardized modular units.

Inventive Principle:
Principle #1Segmentation

2Power

If multiple alternators are connected to increase output, then power generation is improved, but device complexity increases

Engineering Contradiction:
Improveoutput powerVSAvoidalternator system complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

Multiple alternator modules are merged into a coordinated system where each module consists of a magnetic connector, magnetic bar, and stator assembly. The modules operate independently on different wheels but contribute cumulatively to the total power output, achieving increased power generation while maintaining relatively simple individual module designs that can be replicated.

Inventive Principle:
Principle #5Merging (Combining)

3Use of energy by moving object

If physical contact is made between the magnetic bar and alternator, then energy transfer efficiency is improved, but wear and maintenance increase

Engineering Contradiction:

Solution Approach 1:

The system replaces direct mechanical contact between the magnetic bar and alternator components with magnetic field interaction. The magnetic bar generates a magnetic field that induces current in the stator windings without physical contact, eliminating wear and friction while maintaining efficient energy transfer through electromagnetic induction.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Duration of action of moving object

If more batteries are added to increase range, then energy capacity is improved, but vehicle weight increases

Engineering Contradiction:

Core Design Contradiction:
Duration of action of moving objectVSWeight of moving object

Solution Approach 1:

The alternator system enables the vehicle to recharge its own battery during operation through regenerative braking and wheel-driven alternators. This self-service capability extends vehicle range without requiring additional battery weight, as the system generates electricity during normal vehicle operation to replenish battery charge.

Inventive Principle:
Principle #25Self-service

AI summary

An improved alternator system for an electric vehicle. The system includes a magnetic connector attached to a rim of a vehicle wheel. The magnetic connector is connected to a magnetic bar. The magnetic bar increases the magnetic field produced by the magnetic connector. The magnetic bar is magnetically connected to a rotator located within an alternator. As the rim rotates the magnetic bar will be rotated causing the rotator within the alternator to rotate. This will engage the alternator to produce power.
