Racket Sports TRIZ Cases
- Wooden Baseball Bat Barrel Compression and Shaping
A compressing tool with a ceramic roller shapes the wooden bat barrel to increase surface hardness.
- Adjustable Laser-Sensor System for Swing Path Replication
Dynamic laser orientation adapts to various swing paths while inertial sensors deliver immediate feedback, enabling users to replicate desired motion forms.
- Sports Grip With Resilient Lobes For Vibration Damping
Resiliently deformable materials absorb vibrations transmitted through bats, reducing discomfort from impact forces.
- Flexible Band Grip Securing for Baseball Bats
A circular flexible band secures a sports stick wrap through elastic expansion and press fit.
- Segmented Baseball Bat Barrel for BBCOR Compliance
Separate proximal and distal barrel members allow material tuning that meets the 0.500 BBCOR limit while maintaining durability.
- Golf Club Head Cover with Magnetic Segmentation
Segmented head and shank portions use magnets to replace elastic sleeves, preventing snagging on equipment while securing oversized club heads.
- Tennis Racquet Training Device with Spring Biased Detent
A tennis racquet training device uses a spherical member and spring biased detent for secure attachment.
- Single-Wall Composite Bat Using Quartz Fiber Lamina
Orienting unidirectional quartz fibers at opposing angles in a single-wall bat reduces manufacturing complexity while maintaining barrel durability.
- Golf Club Attachment Cuff Reduces Wrist Tension
Intermediary cuff attachment reduces wrist tension, enabling lighter grip force to preserve lag angle and increase club head speed.
- Golf Swing Analyzer Using Inertial Sensors for Bending Moment
Replacing complex optical systems, inertial sensors measure club acceleration to compute bending moment and torque without cumbersome strain gauges.
- Bat Barrel Vibration Dampening and Performance Governing
A bat barrel uses a polyurethane spacer and internal tubular member to manage vibration transfer.
- Lacrosse Stick Shaft Heating Apparatus for Cold Weather Dexterity
Heating apparatus warms lacrosse stick shafts via Joule heating, resolving the contradiction between cold weather warmth and manual dexterity.
- Pressure Mat Golf Club Selection via Load Factor Analysis
A pressure sensing mat measures vertical and lateral forces during a golf swing to calculate load factors for club selection.
- Magnetic Feedback Swing Trainer for Head Position Control
A swing training apparatus uses a magnet and ferromagnetic button to provide auditory feedback when the user's head remains down during the swing.
- Sports Paddle Face Plate with Smooth and Roughened Regions
A sports paddle face plate uses separate smooth and roughened regions to reduce hand irritation during two-handed shots while maintaining high spin impartation.
- Hockey Stick Blade Textured Zone Puck Control
Textured zones on the blade increase friction for better puck handling while reduced areas prevent slippage during shots.
- Multi-Wall Composite Bat Handle for Vibration Reduction
Segmented metal and composite bat handles with internal gaps expand the sweet spot while mitigating structural failure risks.
- Bat Barrel Internal Supports Prevent Rolling Modification
Internal supports and retaining members prevent fiber fracturing during rolling, maintaining ball exit speed within regulatory limits.
- Unitary Lacrosse Stick Composite Molding
A unitary lacrosse stick merges a composite handle and flexible head via molding to create a durable, balanced sports equipment structure.
