Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex blocking systems are used to prevent mudguard detachment, then reliability improves, but device complexity and installation time increase

Engineering Contradiction:

Improvemudguard attachment stabilityVSAvoidmounting system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mounting system is divided into separate functional elements: mounting brackets attached to the frame, and corresponding receptacles on the mudguard. This segmentation allows each component to be optimized independently while simplifying the overall assembly process and reducing complexity compared to integrated complex systems.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mounting brackets are pre-attached to the vehicle frame during manufacturing or prior setup. This preliminary action enables the mudguard to be quickly installed by simply engaging its receptacles with the pre-positioned brackets, significantly reducing installation time while maintaining reliable attachment.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If complex blocking systems are used to prevent mudguard detachment, then reliability improves, but installation time increases

Engineering Contradiction:

Improvemudguard attachment stabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention replaces complex mechanical blocking systems with a simplified receptacle-bracket engagement mechanism. This substitution eliminates the need for multiple fasteners, adjustment mechanisms, or complex locking systems, reducing installation time to a simple snap-fit or bolt-through operation while maintaining attachment reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If radial expansions with mounting brackets are used, then ease of operation improves, but manufacturing precision requirements increase

Engineering Contradiction:

Improvemounting simplicityVSAvoidradial expansion positioning accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The radial expansions are designed with standardized mounting brackets that can accommodate multiple mounting configurations and bracket types. This universality allows the same radial expansion design to be used across different mudguard sizes and vehicle types, reducing the need for high-precision custom positioning while maintaining ease of operation.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting system incorporates adjustable parameters such as bracket positioning tolerances and receptacle clearance dimensions. By designing with appropriate parameter ranges rather than fixed precise dimensions, the system accommodates normal manufacturing variations while maintaining ease of installation and reliable attachment.

Inventive Principle:

Principle #35Parameter changes
