Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If drawing lots for the vehicle is used to ensure identical performance, then vehicle performance uniformity is improved, but resource consumption and cost outlay increase significantly

Engineering Contradiction:

Improvevehicle performance uniformityVSAvoidresource consumption

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system enables vehicles to automatically self-adjust their performance parameters without external intervention. Each vehicle autonomously detects its own characteristics and modifies its operation to achieve uniform performance, eliminating the need for organizers to manually configure and monitor each vehicle, thereby reducing resource consumption while maintaining reliability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically changes operational parameters (such as power output, injection timing, valve timing) based on detected vehicle characteristics and race conditions. This allows automatic compensation for manufacturing tolerances and wear, ensuring uniform performance without requiring physical modification of vehicles or extensive resource allocation

Inventive Principle:

Principle #35Parameter changes

2Weight of moving object

If ballasting technique is used to compensate driver weight differences, then driver weight equality is improved, but vehicle performance uniformity remains compromised due to weight distribution effects

Engineering Contradiction:

Improvedriver weight equalityVSAvoidvehicle performance uniformity

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

Instead of physically modifying vehicle weight through ballasting, the system changes operational parameters (power output, torque characteristics, acceleration profiles) to compensate for driver weight differences. This achieves performance uniformity without the negative effects of altered weight distribution, maintaining both driver equality and vehicle performance reliability

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system replaces the mechanical ballasting approach with an electronic control system that adjusts engine/motor parameters. This substitution eliminates the need for physical weight additions while achieving the same performance equalization goal, thereby maintaining vehicle performance uniformity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If seals are applied to mechanical and electronic components to guarantee uniform performance, then component performance uniformity is improved, but any alterations to unsealed components and failure to compensate for driver morphology are not addressed

Engineering Contradiction:

Improvecomponent performance uniformityVSAvoidcompensation for driver morphology

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts operational parameters based on detected vehicle characteristics and driver morphology. This allows compensation for both manufacturing variations and driver differences without requiring seals or physical modifications, maintaining adaptability while achieving precision

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system continuously monitors vehicle performance and driver characteristics, using this feedback to automatically adjust parameters in real-time. This closed-loop approach ensures compensation for both component variations and driver morphology differences, enhancing adaptability while maintaining precision

Inventive Principle:

Principle #23Feedback

AI summary

A method for automatic adjustment of the performance of a vehicle may include detecting at least one significant physical quantity for checking the performance of the vehicle; defining at least one pair of reference indicators correlated with that physical quantity; saving at least one value of a said reference indicator in a predetermined nominal reference condition; detecting at least one value of a said reference indicator in a real operating condition of the vehicle; comparing said nominal reference indicator and real reference indicator and, if their values are different from each other, and implementing a correction of the driving power of the vehicle to compensate for the difference ascertained.
