Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fluid-filled core is used in a golf ball, then the ball can achieve enhanced spin control and distance, but the internal structure becomes more complex requiring partitioning into sub-chambers
Solution Approach 1:
The fluid-filled chamber is partitioned into multiple sub-chambers using internal structures (such as spokes or radii) that extend from the center to the outer surface. This segmentation allows the fluid to flow through defined pathways while maintaining structural organization, thereby achieving spin control without excessive complexity.
Solution Approach 2:
Different regions of the core are given different properties through the internal structures. The internal structures create zones of varying fluid flow resistance and interaction characteristics, allowing localized optimization of spin control in specific areas while maintaining overall ball performance.
2Reliability
If internal structures are added to partition the fluid chamber, then spin control improves, but the manufacturing process becomes more difficult
Solution Approach 1:
The core is divided into modular sections with internal structures that can be formed as integral parts of the core during manufacturing. This segmentation allows for standardized manufacturing processes while achieving the desired spin control through the geometric configuration of the internal structures.
Solution Approach 2:
The core combines different materials (such as titanium alloys and polymers) in a composite structure where the internal structures are formed as part of the composite material matrix. This approach integrates the internal structures into the manufacturing process rather than requiring separate assembly steps.
3Duration of action of moving object
If the fluid chamber is partitioned into sub-chambers, then the golf ball achieves better spin decay control, but the core structure becomes more complex
Solution Approach 1:
The fluid chamber is segmented into sub-chambers that are connected through controlled pathways. This segmentation creates multiple fluid flow paths that interact with the internal structures in a coordinated manner, extending spin control duration while maintaining structural efficiency through the modular sub-chamber design.
Solution Approach 2:
The internal structures are designed to dynamically interact with the fluid flow within the sub-chambers. The structures create varying flow patterns and resistances that adapt to the spin conditions, providing controlled spin decay while the modular nature of the sub-chambers keeps the overall structure manageable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances spin control and distance by allowing fluid flow within the core, improving the golf ball's coefficient of restitution and initial velocity, resulting in a more consistent and effective golfing experience.
Implementation Method 1
A fluid is placed within an interior chamber of a shell of the core. The core has a plurality of internal structures partitioning the interior chamber into a plurality of sub-chambers. The fluid is allowed to flow through each of the plurality of sub-chambers.
Implementation Method 2
The fluid affects the spin of the golf ball. The internal structures affect the flow of the fluid when the golf ball is struck with a club, which results in the spin decay of the golf ball being affected by the flow of the fluid.
