Upper Body Trainer One-Way Flywheel Drive for Bidirectional Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing upper body exercise apparatuses are cumbersome to switch between modes requiring and not requiring a seat, and lack flexibility in user movement options.
Innovation Solution
An exercise apparatus with a frame and a physical exercise device featuring synchronized or independent rotation of left and right moving members, driven by a mechanism with clutch sprockets ensuring flywheel rotation in one direction regardless of member direction, and adjustable positioning for user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat is made detachable to allow switching between sitting and standing exercise modes, then the adaptability is improved, but the ease of operation deteriorates due to the troublesome process of detaching and reinstalling the seat
Solution Approach 1:
The seat assembly is designed with movable and adjustable components that allow it to transition between different positions and configurations. The seat can be easily repositioned along the frame without complete detachment, enabling quick switching between sitting and standing exercise modes while maintaining ease of operation.
2Reliability
If the driving mechanism uses one-way transmission with clutch sprockets to ensure flywheel rotation in one direction, then the reliability is improved, but the device complexity increases
Solution Approach 1:
Clutch sprockets are introduced as intermediary components between the moving members and the flywheel. These clutch sprockets selectively engage and disengage to control power transmission, ensuring the flywheel rotates only in the predetermined direction while allowing the moving members to rotate in both directions. This intermediary mechanism provides reliable directional control without requiring complex multi-component systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides increased user freedom and consistency in exercise movements, allowing seamless switching between forward and backward rotations and adjustable height for different user positions.
Implementation Method 1
Each of the sprockets and the pulley are coupled by one-way transmission, any sprocket rotating in the forward direction will cause the pulley to rotate in the forward direction, and any sprocket rotating in the reverse direction will not cause the pulley to rotate
Implementation Method 2
The physical exercise device has a flywheel, a left moving member, a right moving member

AI summary
An upper body exercise apparatus includes a frame body and a physical exercise device mounted on the frame body. The physical exercise device has a flywheel, a left moving member, a right moving member and a driving mechanism coupled to the flywheel and the left and right moving members. The driving mechanism has a left driving mechanism and a right driving mechanism. The left driving mechanism is mounted between the left moving member and the flywheel to drive the flywheel to rotate in a predetermined rotational direction, regardless of whether the left moving member is operated to be rotated in a forward direction or a reverse direction. The right driving mechanism is mounted between the right moving member and the flywheel to drive the flywheel to rotate in the predetermined rotational direction, regardless of whether the right moving member is operated to be rotated in the forward direction or the reverse direction.
