Muscle Exercising Devices TRIZ Cases

Replacing wheel-track systems with a flexible member linkage eliminates rolling noise while maintaining smooth elliptical pedal motion.

A specialized seat supports the thigh and hip to enable backward leg movement.

A treadmill deck elevation mechanism uses a handle-linked linkage and torque adjuster to change mechanical advantage.

Adjustable strap loops around limbs to isolate target muscles, eliminating grip stress on joints and forearms.

Sliding foot anchor corrects improper form by moving back when legs lift, preventing injury without complex sensors.

Pivotally attached legs with clamping devices enable height adjustment, resolving stability versus adaptability trade-offs in portable exercise equipment.

A wind resistance spinning bike uses a drive assembly to rotate a fan and swing armrests for comprehensive exercise.

Four-bar linkage system with coupler bars and wheel units generates rotational and swinging movements for a multi-function exercise device.

Spheroidality and dimensionality change enable curved rolling paths that resolve the trade-off between repetitive linear motion and versatile muscle engagement.

Segmented walls with spaced protuberances allow resistance bands to weave through empty spaces, adjusting tension for full-body exercises without slippage.

A partial cylindrical barrel exercise apparatus features a composite upper surface formed by merging two arcuate surfaces of different radii.

Curved exercise belt maintains profile via sliding constraint elements, eliminating bearing friction and gear noise while ensuring synchronized rotation.

Segmented endcap inserts and a one-way valve provide variable inhalation and exhalation resistance to simulate high-altitude conditions.

A rotational component orients resistance bands horizontally or vertically to target specific ankle motion planes.

A multi-purpose exercise system featuring a foot glider assembly with adjustable straps and a handheld roller unit with a dynamic locking mechanism.

A gripping handle uses a flexible connector to tighten around the hand during pulling force application.

An elastic member resists pedal movement relative to the support part, preventing joints from exceeding their safe range of motion.

A collapsible dip apparatus uses support bars to attach resistance bands that provide upward force for assisted exercises.

Dynamic belt motion replicates outdoor trajectories to engage trunk muscles, resolving inadequate aerobic effects from conventional fixed-path devices.

Looped straps bypass grip strength to reduce forearm stress and improve wrist range of motion.

A guided weight holder stabilizes loads during hip belt exercises using a specialized rack mechanism.

A barbell supporting block attaches to the barbell to adjust bench press starting height and range of motion.

A ring toss game apparatus uses modular peg targets to create varied scoring opportunities for competitive play.

A drive screw mechanism adjusts the swing arm arc to vary stride length without altering vertical motion for interval training.

An elastic resistance band incorporates a coaxial inner flexible member that changes shape under force to secure the device around objects.

Motorized weightlifting machine adjusts resistance via proximity and location sensors, eliminating manual plate changes to maintain continuous workout flow.

Segmented base and contoured padding elevate the torso to isolate lower abdominal muscles, addressing inadequate support for injury rehabilitation.

A gymnastic handle uses a flexible inner sheath to house the exercise cable and absorb tension forces during operation.

Adjustable slide member on horizontal rail targets multiple muscle groups while minimizing injury risk through versatile movement patterns.

Segmented chair sections engage core muscles by allowing the upper back support to pivot, resolving limited upper body engagement in traditional designs.

Segmented sliding components resolve the contradiction between targeted muscle engagement and device complexity.

Movable handles on a circular frame allow 360-degree movement, targeting stabilizer muscles that conventional linear machines miss.

A therapeutic exercise device uses height-adjustable legs and elastic straps to improve arm mobility and strength in infants with arthrogryposis.
