Tri-Power Exerciser Integrating Linear Core Motion Into Rotational Torque
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise equipment does not allow riders to simultaneously input torque into a resistance flywheel using both the up and down vertical rotational oscillations of their arms, leg rotation of the pedals, and sliding their seat back and forth using their core muscle groups, limiting the effectiveness and efficiency of workouts.
Innovation Solution
The Tri-Power Exerciser incorporates a unique design with an exerciser bike frame, forearm bars, inverted racks, pinion gears, one-way bearings, and a chain system that converts linear motion from the rider's core, arms, and legs into rotational torque to power the crank axle, enabling simultaneous engagement of all major muscle groups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If riders use conventional exercise equipment that allows only single muscle group exercise, then the equipment structure remains simple, but workout efficiency and calorie burn are limited
Solution Approach 1:
The patent combines three separate exercise functions (leg pedaling, arm cranking, and core sliding) into a single integrated machine. All three functions simultaneously drive a common resistance mechanism through a unified drive train, allowing riders to exercise multiple muscle groups at once while sharing a single resistance system.
Solution Approach 2:
The exercise machine is designed with multi-functionality, allowing riders to perform three different types of exercises (lower body cycling, upper body rowing, and core sliding) on one device. Each function can be used independently or in combination, providing versatile workout options.
2Loss of time
If riders exercise muscle groups separately on different equipment, then each exercise can be optimized for its specific function, but total workout time increases
Solution Approach 1:
The patent merges three exercise modalities into one simultaneous activity. Riders can engage all three muscle groups at the same time, reducing total workout duration by at least 40% compared to sequential exercise on separate machines.
Solution Approach 2:
The machine allows dynamic configuration where riders can adjust the intensity and engagement level of each exercise function independently. The resistance system dynamically responds to combined input from all three exercise modes, allowing flexible workout programming.
3Device complexity
If the machine uses a direct connection between muscle groups and resistance, then the mechanism remains simple, but the ability to convert linear motion to rotational torque is limited
Solution Approach 1:
The patent introduces a belt and pulley system as an intermediary mechanism between the linear sliding motion of the core exercise and the rotational crank motion. This intermediary converts the linear motion from the sliding seat into rotational torque that drives the resistance flywheel, enabling power transfer between different motion types.
Solution Approach 2:
The patent replaces a purely mechanical direct-drive system with a belt-driven system that allows for more efficient torque transmission. The belt and pulley arrangement provides mechanical advantage and enables the conversion of linear motion to rotational motion more effectively than a direct mechanical connection.

AI summary
Tri-Power Exercising device allows a rider to simultaneously, or on demand, exercise virtually all muscle groups in his lower and upper body. The device includes a bicycle frame, pedals, forearm bars, sliding seat, computer and electronic display recommending energy modulation amounts from various muscle groups to optimize physical performance on any given trek. Because riders can exercise virtually all muscle groups at once, they reduce their exercising time, continuously builds muscle tissue throughout their whole body, and exercises their cardiovascular and respiratory systems completely. Riders operate the device by rotating legs on the pedals, rotationally oscillating the forearm bars up and down with their arms and shoulders, and then use core muscles to pull and push the seat back and forth on the slider. Inverted racks, pinion gears, and one-way bearings turn this linear power from the oscillating forearm bars and sliding seat into torque that rotates the crank axle.
