Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If club head complementary components are used to serve different purposes in different stages of a golf tournament, then the functionality and versatility of the golf club head is improved, but the components are prone to scratching, cracking, and bursting which reduces structural strength and creates safety hazards

Engineering Contradiction:

ImprovefunctionalityVSAvoidstructural strength

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The protection component is made of carbon fiber impregnated with thermoplastic polyurethane, creating a composite material structure that combines the strength and stiffness of carbon fiber with the toughness and impact resistance of thermoplastic polyurethane. This composite structure protects the club head complementary component while maintaining its functional performance.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The protection component acts as a flexible protective shell that covers the club head complementary component. This shell is designed to be resilient and able to absorb impact forces, preventing cracking and bursting while allowing the underlying component to maintain its structural integrity and functionality.

Inventive Principle:

Principle #30Flexible shells and thin films

2Duration of action of moving object

If club head complementary components are subjected to repeated hitting and accidental impact, then the golf club head can be used extensively in various tournament stages, but the components suffer from scratching and cracking which adversely affect appearance and reduce structural strength

Engineering Contradiction:

Improveusage durationVSAvoidstructural strength

Core Design Contradiction:

Duration of action of moving objectVSStrength

Solution Approach 1:

The protection component is installed beforehand on the club head complementary component to provide a cushioning layer that absorbs and distributes impact forces. This pre-installed protective shell prevents direct transmission of impact forces to the underlying component, reducing scratching and cracking during repeated use.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The carbon fiber thermoplastic polyurethane composite material provides both strength and toughness, enabling the protection component to withstand repeated impacts and accidental forces while protecting the club head complementary component from damage throughout extended usage.

Inventive Principle:

Principle #40Composite materials

3Object-affected harmful factors

If club head complementary components are protected to prevent cracking and bursting, then user safety and structural integrity are improved, but the complexity of the club head structure increases

Engineering Contradiction:

ImprovesafetyVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The protection system is segmented into a separate protection component that can be independently manufactured and installed on the club head complementary component. This segmentation allows the protective function to be added without fundamentally redesigning the entire club head structure, maintaining relative simplicity while improving safety.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The protection component is designed as a relatively simple shell structure that covers the club head complementary component. This shell approach provides comprehensive safety protection against cracking and bursting while adding minimal structural complexity compared to more complex reinforcement systems.

Inventive Principle:

Principle #30Flexible shells and thin films
