Rotatable Push-Up Handle Reducing Joint Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push-ups place stress on wrists, elbows, and shoulders, and restrict natural muscle and joint rotation, limiting the effectiveness of the exercise.
Innovation Solution
A push-up exercise unit with rotatable devices for each hand, featuring a handle assembly, rotatable handle support structure, and a bearing assembly that allows for rotation, reducing strain on joints and enabling natural muscle engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If hands are placed directly on a non-movable hard surface, then stability is maintained, but stress is placed on wrists, elbows and shoulders
Solution Approach 1:
The patent applies the dynamics principle by making the hand support surface rotatable rather than fixed. The bearing assembly allows the handle support structure to rotate relative to the base support, enabling natural arm rotation during push-ups while maintaining stability. This dynamic element resolves the contradiction by allowing movement that reduces joint stress without compromising overall stability.
2Device complexity
If hands are placed directly on a non-movable hard surface, then exercise simplicity is maintained, but natural muscle and joint rotation is prevented
Solution Approach 1:
The rotatable handle support structure with bearing assembly provides the necessary adaptability for natural arm rotation while maintaining relative simplicity. The rotation mechanism allows dynamic adjustment to natural movement patterns without requiring complex adjustable components or multiple parts.
3Adaptability or versatility
If a rotatable handle assembly is used, then natural arm rotation is enabled, but device complexity increases
Solution Approach 1:
The bearing assembly serves as an intermediary element that enables rotation between the handle support structure and base support. This intermediary component provides the necessary adaptability for natural arm rotation while keeping the overall device structure relatively simple and manageable.
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
The device allows for natural arm rotation during push-ups, engaging more muscle groups and reducing joint stress, thereby enhancing the workout experience while maintaining stability on various surfaces.
Implementation Method 1
a bearing assembly operatively attached within the handle support structure to permit rotation of the handle assembly and handle support structure

AI summary
A push-up exercise unit and device is described which may enable a user to move with his or her body's natural rotation to engage additional muscle groups with reduced stress on joints. The device includes a pair of rotatable devices, one for each hand. Each rotatable device includes a handle assembly, a rotatable handle support structure, a fixed base support, and a bearing assembly operatively attached within the handle support structure to permit rotation of the handle assembly and handle support structure. The handle assembly is removable from a top surface of the handle support structure, to be inserted into another surface of the handle support structure to configure the unit for stowage.
