Angled Cylindrical Disc for Inline Skating Maneuvers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing toe picks on inline figure skates are blunt and lack the necessary angled surface area to enhance performance for jumps, spins, and footwork maneuvers, limiting the skater's ability to execute complex maneuvers effectively.
Innovation Solution
A 45 mm long × 29 mm wide cylindrical disc with a continuous curved profile and angled edges is designed to fit the PIC inline skate, providing optimal contact angles for jumps and spins, and featuring flat slanted edges for strong push-offs, enhancing traction and maneuverability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a blunt cylindrical pick is used, then the structure is simple and easy to manufacture, but the performance for jumps, spins, and footwork maneuvers is limited
Solution Approach 1:
The patent applies curvature by transitioning from a blunt cylindrical pick to a curved pick with a continuously curved outer surface. The curved profile creates optimal contact angles with the skating surface, enabling enhanced performance in jumps, spins, and footwork maneuvers while maintaining the simple molded manufacturing process
2Adaptability or versatility
If a curved profile pick is designed, then maneuver execution capability is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The patent changes the geometric parameters of the pick by introducing a curved profile with specific dimensions (45mm length, 29mm width) and continuous curvature. This parameter modification enhances maneuver execution capability while the curvature is achieved through standard molding processes, preventing excessive complexity increase
3Adaptability or versatility
If a curved profile pick is designed, then optimal contact angles for jumps and spins are provided, but the manufacturing precision requirements increase
Solution Approach 1:
The patent defines specific geometric parameters for the curved profile including length (45mm), width (29mm), and continuous curvature characteristics. These controlled parameter changes achieve optimal contact angles for performance while remaining within achievable manufacturing precision limits through molding processes

AI summary
A specially formed cylindrical disc, set in a fixed position, to be utilized on the PIC® inline skate to allow for jumps and spins in the sport of inline figure skating. The performance pick disc is made of molded rubber or synthetic material. The purpose of the performance pick is to provide enhanced spins, jumps, and footwork common in the sport of inline figure skating. The continuous curved shape of the performance pick discs outer edges provides a toe-in angle of between 0 and 22 degrees, the optimal angle being between 5 and 12 degrees for jumps and 0 to 5 degrees for spins. In a variation, the outer edges are slanted at an angle between 20 and 45 degrees on both sides continuously around the cylindrically formed disc to provide an optimal surface for push offs common in inline figure skating maneuvers.
