Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rigid materials like plastic, steel, or aluminum are used for latches, then the structural strength and durability are improved, but the risk of damaging delicate seals on panoramic roofs increases

Engineering Contradiction:
Improvelatch structural strengthVSAvoidseal damage risk
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The latch is constructed as a composite structure combining a rigid metal core (steel or aluminum) for structural strength with an outer covering of shock-absorbing material (plastic, rubber, or silicone) that contacts the panoramic roof. This composite design allows the latch to maintain its mechanical strength while the soft outer layer prevents damage to delicate seals during loading and storage operations.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If plastic material is used for latches, then the shock absorption capability is improved, but the durability and strength are reduced due to frequent breaking

Engineering Contradiction:
Improveseal protectionVSAvoidlatch durability
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The latch combines plastic or rubber shock-absorbing material with a metal reinforcement structure. The metal core provides the necessary strength and durability to withstand repeated use, while the plastic or rubber outer layer maintains contact with the panoramic roof and absorbs shocks, preventing seal damage without sacrificing overall latch durability.

Inventive Principle:
Principle #40Composite materials

3Object-affected harmful factors

If rubber material is used for latches, then the flexibility and shock absorption are improved, but the strength is insufficient for heavy panoramic roofs

Engineering Contradiction:
Improveseal protectionVSAvoidload bearing capacity
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The latch uses a metal structural framework (steel or aluminum) to provide the necessary load-bearing capacity for heavy panoramic roofs, while rubber or silicone coverings on the contact surfaces provide shock absorption and flexibility. This composite approach ensures both the strength needed to support heavy loads and the flexibility required to protect delicate seals.

Inventive Principle:
Principle #40Composite materials

4Strength

If silicone material is used for latches, then the flexibility and durability are improved, but the shock absorption capability is insufficient for sensitive panoramic roofs

Engineering Contradiction:
Improvelatch durabilityVSAvoidseal protection
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The latch combines silicone or rubber material with enhanced shock-absorbing features such as increased material thickness, specialized geometric configurations, or viscoelastic properties. The metal core maintains structural integrity and durability, while the silicone outer layer is designed with sufficient thickness and structural features to provide adequate shock absorption for protecting panoramic roof seals.

Inventive Principle:
Principle #40Composite materials
