Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise apparatuses for chin-ups, pull-ups, and dips are overly complicated and difficult to use, lacking the ability to assist users in pulling their chin above the overhead bar effectively.
Innovation Solution
An exercise apparatus featuring a frame, an overhead assist module with pulleys, a harness, and a cable spool connected to a motor, allowing users to select and adjust positive upward force for assistance in performing these exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If prior art devices are used to assist chin-up, pull-up and dip exercises, then some assistance is provided, but the devices are overly complicated and difficult to use
Solution Approach 1:
The exercise apparatus is divided into distinct functional modules: a support structure, a cable system with pulleys, an adjustable resistance mechanism, and a chin-up bar assembly. Each module independently performs a specific function, allowing the complex assistance system to be constructed from simpler, manageable components that are easier to operate and maintain
Solution Approach 2:
The resistance assistance mechanism is extracted as a separate adjustable module that can be independently configured. The cable and pulley system is separated from the main support structure, allowing users to adjust resistance levels without reconfiguring the entire apparatus, thereby simplifying operation while maintaining assistance capability
2Adaptability or versatility
If prior art devices are used to assist chin-up, pull-up and dip exercises, then some assistance is provided, but the design limitations do not provide means to assist pulling the user's chin above the overhead bar
Solution Approach 1:
The cable system with pulleys is designed to provide resistance assistance for multiple upper body exercises including chin-ups, pull-ups, and dips. The same mechanical system can be adjusted to assist in pulling the chin above the bar, performing standard chin-ups, or executing pull-up variations, making the apparatus versatile and reliable for different exercise requirements
Solution Approach 2:
The resistance mechanism incorporates adjustable tension settings that allow users to dynamically modify the assistance level based on their strength and exercise goals. This dynamic adjustment ensures reliable assistance for challenging movements like getting the chin over the bar while providing appropriate resistance for stronger users performing standard repetitions
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
Enables users to perform full chin-ups and pull-ups by providing adjustable weight assistance and accommodating different user heights, enhancing the ability to complete repetitions with reduced strain on upper body strength.
Implementation Method 1
The overhead assist module includes a set of pulleys, a harness, and a cable spool connected to a motor. A cable, which travels along the set of pulleys, is connected to the harness and the cable spool that can be rotated by the motor.

AI summary
A chin-up/pull-up exercise apparatus is disclosed. The exercise apparatus includes a frame, an overhead assist module, and a chin bar. The chin bar is connected to the frame. The overhead assist module includes a set of pulleys, a harness, and a cable spool connected to a motor. The set of pulleys, which is connected to the frame, is positioned vertically above the chin bar. A cable, which travels on the set of pulleys, is connected to the harness and the cable spool that can be rotated by the motor. The exercise machine enables real, full arm extension pull ups regardless of one's upper body strength with applications for physical therapy; physical exercise training; muscle, tendon, and joint rehabilitation; and upper and lower body strength building.
