Golf Grip Nonpolar Rubber Sebum Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club grips with minute projections for improved anti-slipping performance tend to retain sebum, leading to a slippery surface and reduced head speed due to the sebum retention, causing golfers to unconsciously hold the grip tighter, increasing resistance during swings.
Innovation Solution
A golf club grip with a cylindrical portion made from a rubber composition containing nonpolar rubber (50% or more) and featuring minute projections with a height of 0.07 mm or more and a minimum width of 0.2 mm to 0.8 mm, which absorb sebum and provide an anchor effect within the fingerprint grooves, reducing the perceived slipperiness and allowing for a lighter grip hold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If minute projections are formed on the grip surface to improve anti-slipping performance, then the anti-slipping performance is improved, but the user's sebum is easily attached to the minute projection and retained on the grip surface, causing the grip surface to become slippery
Solution Approach 1:
The patent changes the geometric parameters of the projections by specifying a height of 0.07 mm or more and a minimum width at the bottom of 0.2 mm to 0.8 mm. These specific parameter ranges allow the projections to effectively engage with fingerprint grooves while minimizing sebum accumulation, resolving the contradiction between anti-slipping performance and sebum retention.
Solution Approach 2:
The patent uses a rubber composition containing nonpolar rubber in an amount of 50 mass % or more. The nonpolar rubber material properties are specifically selected to resist sebum attachment while maintaining the mechanical integrity and anti-slipping characteristics of the projections, thus addressing both requirements simultaneously.
2Strength
If shallow grooves are made between projections to maintain projection strength, then the projection strength is maintained, but the user's sebum attached to the minute projection is retained on the grip surface, lowering the dryness of the grip surface
Solution Approach 1:
The patent specifies precise dimensional parameters for the projections (height of 0.07 mm or more, minimum width at bottom of 0.2 mm to 0.8 mm) which inherently provide sufficient structural strength without requiring additional grooves. This parameter optimization eliminates the need for grooves that would trap sebum, thus maintaining both strength and dryness.
3Stability of the object's composition
If the user holds the grip tight to compensate for slipperiness, then the grip stability is improved, but the head speed is lowered due to increased resistance
Solution Approach 1:
The patent creates a grip surface that maintains its anti-slipping properties without requiring the user to apply excessive force. By using projections with specific dimensions (0.07 mm height, 0.2-0.8 mm minimum width) that effectively engage with fingerprints, the grip provides stable holding with minimal hand pressure, allowing faster swing speeds.
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 grip maintains dryness, enhances anti-slipping performance, and reduces resistance, resulting in improved head speed and grip feel during swings.
Implementation Method 1
The grip primarily contains a nonpolar rubber and can absorb the user's sebum attached to the minute projection, thereby keeping the grip surface dry
Implementation Method 2
the minute projection can enter inside the groove of the user's fingerprint. As a result, the minute projection exerts an anchor effect inside the groove of the user's fingerprint, and thus the anti-slipping performance is improved
