Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the head size is increased to improve ball catchability, then the ball catchability is improved, but the air resistance increases
Solution Approach 1:
The patent divides the head's projected area into two distinct regions: a first region (Afθ) that generates air resistance promoting face rotation, and a second region (Abθ) that generates air resistance opposing face rotation. By segmenting the aerodynamic function across different spatial zones of the head, the design optimizes the balance between ball catchability and controlled air resistance effects during the downswing.
2Length of moving object
If the projected area distribution is optimized to reduce air resistance, then the flight distance is improved, but the ball catchability may be compromised
Solution Approach 1:
The patent applies different aerodynamic qualities to different local regions of the head. The first region (Afθ) is designed with specific projected area characteristics to generate beneficial air resistance for face rotation, while the second region (Abθ) is designed with different characteristics to provide opposing air resistance. This local differentiation allows simultaneous optimization of ball catchability and flight distance through controlled aerodynamic interactions.

AI summary
A state of a golf club head placed such that a shaft axis line is vertical to a horizontal plane and a normal line is parallel to a first perpendicular plane on which the shaft axis line lies is defined as a 0-degree state. A direction parallel to the first perpendicular plane and parallel to the horizontal plane is defined as a projection direction. A projected area of the head projected in the projection direction when the head is rotated by θ° about the shaft axis line toward a back side from the 0-degree state is denoted by WAθ. WAθ is divided by the shaft axis line into a first region (having an area denoted by Afθ) and a second region (having an area denoted by Abθ), and a difference (Afθ-Abθ) is denoted by Sθ. S90 is -4500 (mm2) or less. S15 is 4700 (mm2) or less.
