Dumb-Bells TRIZ Cases
- Weighted Pet Leash Cover for Discreet Strength Training
A weighted pet leash cover integrates high-density material into a standard mechanism.
- Weight-Adjustable Dumbbell Gear Fixing Mechanism
Gear fixing mechanism pushes hanging member to nearest gear position for full dumbbell plate engagement.
- Weight Modification Clamp for Precise Dumbbell Adjustments
Pivoting plates and tensioning mechanism secure a clamp to dumbbell bars, enabling precise weight adjustments below standard increments.
- Dual Action Weightlifting Machine Low Position Horizontal Guide
A dual action weightlifting machine relocates horizontal guides below the exercise bar path, reducing traveling frame weight and inertia for smoother motion.
- Exercise Bar Connector Assembly with Spring-Loaded Pin Lock
A connector assembly joins exercise bar segments using threaded portions and a spring-loaded pin lock for secure attachment.
- Motorized Treadmill with Sensor-Based Exercise Verification
Current and optical sensors detect user presence on a motorized treadmill belt, preventing falsified exercise data transmission.
- Kettlebell Casting with Interlocking Handle for Secure Connection
Casting the main body around an interlocking handle eliminates welding complexity while ensuring a secure bond that prevents detachment through fracture.
- Weight Plate Alignment Cradle for Selector Shaft Insertion
Angled cradle walls constrain lateral and vertical plate movement to align central openings with the selector shaft, preventing insertion obstruction.
- Quick Release Weight Retaining Device Ejector Mechanism
Segmented grapple and retainer design uses an ejector to force the arm out of the seat when weight lifts, eliminating bar jerking from angled release surfaces.
- Hinged Dumbbell Holder With Rotation Assist
A hinged dumbbell holder system elevates weights using a hydraulic rotation assist mechanism.
- Adjustable Dumbbell Weight Selector Mechanism
Universal plate design with nested L-shaped selectors simplifies adjustment, reducing mechanism complexity while maintaining versatile weight ranges.
- Weight-Adjustable Dumbbell Telescopic Rod Mechanism
A limit structure constrains axial movement between plates while rotation adjusts length, replacing manual nut assembly.
- Adjustable Dumbbell Micro-Weight Adjustment Mechanism
A dumbbell assembly uses half-weight elements and a latch-beam mechanism to secure specific mass increments along the handle bar.
- Moveable Rack Mount Apparatus Tool-Free Attachment
A moveable rack mount apparatus with a reversible locking mechanism enables tool-free attachment of exercise equipment.
- Exercise Ring With Guide Track For Variable Resistance Training
A portable exercise ring uses a movable carriage on a guide track to apply variable resistance for multi-angle muscle strengthening.
- Stackable Handheld Weight Plates with Self-Latching Connector
Segmented plates with self-latching connectors resolve storage space constraints while maintaining versatile weight adjustment.
