Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a putter is constructed from multiple body members made of different materials with varying densities, then weight distribution and balance are improved, but manufacturing complexity increases

Engineering Contradiction:

Improveweight distributionVSAvoidmanufacturing complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The putter head is divided into multiple body members (first body member, second body member, third body member) that can be manufactured separately and then assembled together. This segmentation allows each component to be optimized for specific weight distribution requirements while simplifying the overall manufacturing process compared to creating a single complex multi-material component.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The putter employs composite construction by combining multiple body members made of different materials with varying densities. This allows precise control over the overall weight distribution and balance characteristics of the putter, enabling optimization for sound, feel, and forgiveness without requiring a single complex material system.

Inventive Principle:

Principle #40Composite materials

2Measurement precision

If sightlines are incorporated on multiple body members, then alignment accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvealignment accuracyVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The sightlines are integrated directly into the structure of the body members themselves rather than being separate add-on components. By merging the alignment feature with the structural elements, the design achieves improved alignment accuracy without proportionally increasing device complexity, as the sightlines become part of the manufacturing process for the body members.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If adjustable weight components are added, then customization options are improved, but ease of manufacture decreases

Engineering Contradiction:

Improvecustomization optionsVSAvoidease of manufacture

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The putter incorporates adjustable weight components that allow the center of gravity to be modified after manufacturing. This dynamic adjustability provides customization options for sound, feel, and forgiveness while using standardized adjustment mechanisms that maintain ease of manufacture through simple addition and adjustment steps rather than complex reconfiguration processes.

Inventive Principle:

Principle #15Dynamics
