Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional attachment systems are used for diffusers, then installation and maintenance procedures become complex and difficult, but the connector system structure becomes simpler with tongue and groove flanges

Engineering Contradiction:
Improveinstallation and maintenance proceduresVSAvoidconnector system structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The connector system is divided into separate modular components including tongue flanges, groove flanges, and fixing clamps that can be independently manufactured and assembled. This segmentation simplifies the overall installation and maintenance procedures while managing structural complexity through standardized interfaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Tongue and groove flanges serve as intermediary elements between the diffuser and the exhaust system, providing a standardized mechanical interface that simplifies connection and disconnection procedures while maintaining structural integrity through the mediator components.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional fastening methods are used for outlet nozzles and side connectors, then durability is reduced and maintenance costs increase, but the fixing clamp system provides higher strength and safety

Engineering Contradiction:
Improvedurability and safetyVSAvoidmanufacturing and maintenance procedures
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The fixing clamp system merges multiple fastening functions into a single integrated component that simultaneously provides clamping force, positioning, and structural support. This combination increases durability and safety while simplifying manufacturing and maintenance compared to traditional multi-component fastening systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fixing clamps are designed with adjustable and removable characteristics, allowing dynamic adaptation during installation and maintenance. This dynamic design enables easy removal and reinstallation of outlet nozzles and side connectors, reducing maintenance costs while maintaining high durability during operation.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If fixed-position attachment systems are used, then adaptability to different vehicle types is limited, but the rotating connector system provides 360-degree rotation and better versatility

Engineering Contradiction:
Improveadaptation to different vehicle typesVSAvoidrotating mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connector system incorporates 360-degree rotation capability through a dynamic joint design that allows the diffuser to be positioned at any angle relative to the exhaust system. This dynamic adaptability enables installation on various vehicle types without requiring complex fixed-position mounting systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The tongue and groove flange interface with rotating capability serves multiple functions: mechanical connection, angular adjustment, and positioning. This multi-functional design provides universal adaptability to different vehicle types while managing complexity through a single integrated interface system.

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