Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If supplementary systems are used to increase engine power by withdrawing air from braking system, then additional acceleration is achieved, but vehicle dimensions and production costs increase remarkably

Engineering Contradiction:
Improveengine powerVSAvoidvehicle dimensions
Core Design Contradiction:
PowerVSVolume of moving object

Solution Approach 1:

The invention merges the air storage function into the existing braking system components. The compressed air tank is integrated into the braking system architecture, and the air intake valve utilizes the existing braking air line infrastructure. This consolidation eliminates the need for separate large external tanks and complex pneumatic connections, thereby achieving additional engine power without increasing vehicle dimensions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The compressed air tank serves dual purposes: it supplies air for the braking system and simultaneously provides compressed air for the acceleration boost function. The air intake valve can draw air from the braking system line for both braking operations and acceleration enhancement. This multi-functionality allows the system to achieve additional acceleration capability without requiring dedicated components that would increase vehicle size.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Power

If large external tanks and high-pressure air compressors are installed, then additional acceleration is achieved, but production and commercialization costs increase considerably

Engineering Contradiction:
Improveengine powerVSAvoidproduction cost
Core Design Contradiction:
PowerVSEase of manufacture

Solution Approach 1:

The system utilizes the vehicle's existing high-pressure air compressor that is already installed for the braking system. Rather than adding a separate high-pressure compressor, the invention makes the existing compressor serve the additional acceleration function by providing compressed air to the intake valve. This self-service approach eliminates the need for expensive additional compression equipment and reduces production costs.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention combines the acceleration boost function with the existing braking air supply infrastructure. The compressed air tank, air intake valve, and associated piping utilize the same components and lines already present for braking operations. This merging of functions eliminates the need for separate expensive components and reduces manufacturing complexity and costs.

Inventive Principle:
Principle #5Merging (Combining)

3Power

If supplementary systems with external tanks are used, then additional acceleration is achieved, but the system complexity increases remarkably

Engineering Contradiction:
Improveengine powerVSAvoidsystem complexity
Core Design Contradiction:
PowerVSDevice complexity

Solution Approach 1:

The invention merges the acceleration boost system with the existing braking air supply infrastructure. The compressed air tank is integrated into the braking system architecture, the air intake valve connects to the existing braking air line, and the control mechanism utilizes the same electronic control unit that manages braking operations. This consolidation significantly reduces system complexity compared to having separate dedicated components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system components serve multiple functions: the compressed air tank provides air for both braking and acceleration boost, the air intake valve can supply air for both purposes, and the electronic control unit manages both braking and acceleration functions. This multi-functionality reduces the number of dedicated components needed, thereby simplifying the overall system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If systems are designed for industrial vehicles with air compressors, then additional acceleration is achieved, but the systems cannot be applied to automobile engines without high-pressure air compressors

Engineering Contradiction:

Solution Approach 1:

The invention creates a universal system that can be applied to both industrial vehicles and automobiles. By utilizing the vehicle's existing air compressor (whether for braking in industrial vehicles or integrated in automobiles) and designing the air intake valve and control mechanism to work with standard pneumatic systems, the system achieves broad compatibility across different vehicle types and engine configurations, ensuring reliable applicability.
