Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the paddle core is made more rigid to meet USAP specifications, then rigidity compliance is improved, but dwell time and spin generation capability deteriorate
Solution Approach 1:
The core is divided into multiple core elements arranged in a grid pattern, with different density configurations in different regions. This segmentation allows the paddle to have varying rigidity and compression characteristics across different areas, enabling compliance with USAP rigidity specifications while maintaining sufficient dwell time for spin generation.
Solution Approach 2:
The core elements have different densities distributed non-uniformly throughout the core structure. Areas with higher density provide increased rigidity for structural compliance, while areas with lower density maintain compression capability for dwell time. This local variation in material properties resolves the contradiction between overall rigidity and localized compression behavior.
2Duration of action of moving object
If the core compression is increased to improve spin generation, then dwell time is improved, but rigidity and structural stability deteriorate
Solution Approach 1:
The core is segmented into multiple elements that can independently compress and rebound. This segmentation allows the core to exhibit non-linear compression behavior where initial compression provides dwell time for spin generation, while the segmented structure prevents catastrophic failure and maintains structural stability even under repeated high-impact conditions.
Solution Approach 2:
The core elements are made from composite materials with specific density characteristics that balance compression compliance and structural rigidity. These composite materials enable the core to compress sufficiently for dwell time while maintaining the structural integrity required for stability.
3Strength
If the core elements are made with higher density to increase rigidity, then structural strength is improved, but compression capability and dwell time deteriorate
Solution Approach 1:
Different regions of the core contain core elements with different densities optimized for their specific functional requirements. Edge regions may have higher density for structural strength and rigidity compliance, while central regions have lower density for maximum compression and dwell time. This spatial variation in material density resolves the contradiction between overall strength and localized compression capability.
