Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid mounting structures are used to securely attach fuel tanks, then structural strength and stability are improved, but impact resistance and stress absorption deteriorate

Engineering Contradiction:
Improvestructural strengthVSAvoidimpact resistance
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The mounting system changes the physical state and mechanical properties of the mounting members by using elastomeric materials that can deform under load. This allows the system to maintain structural strength while absorbing impact energy through elastic deformation, resolving the contradiction between rigidity and impact resistance

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The mounting assembly uses composite construction combining metal brackets with elastomeric mounting members. This composite approach allows the metal components to provide structural strength and the elastomeric materials to provide impact absorption and stress dissipation, simultaneously achieving both requirements

Inventive Principle:
Principle #40Composite materials

2Reliability

If flexible mounting structures are used to absorb impacts, then impact resistance is improved, but structural strength and stability deteriorate

Engineering Contradiction:
Improveimpact resistanceVSAvoidstructural strength
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The elastomeric mounting members are designed with specific durometer hardness values and cross-sectional geometries that allow them to deform controllably under impact loads while maintaining sufficient structural support. This parameter optimization enables the system to be both flexible for impact absorption and strong for structural support

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The combination of rigid metal brackets and flexible elastomeric members creates a composite mounting system where each material performs its optimal function - the metal provides structural strength and the elastomer provides impact resistance, achieving both requirements simultaneously

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If multiple mounting points are used to prevent excessive movement, then stability is improved, but device complexity increases

Engineering Contradiction:
Improvemounting stabilityVSAvoidmounting system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The mounting system divides the fuel tank attachment into multiple discrete mounting points distributed around the tank perimeter. Each mounting point is a separate elastomeric member that independently absorbs stress, providing stable attachment while keeping each individual component simple and the overall assembly straightforward

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The elastomeric mounting members serve multiple functions simultaneously: they provide structural support, absorb impacts, allow thermal expansion, and prevent excessive movement. This multi-functionality achieves mounting stability without requiring additional specialized components, thereby avoiding increased complexity

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