Convex Push-Up Base for Wrist Rotation and Stress Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional push-up exercises cause wrist and forearm stress due to hyperextension, limited muscle engagement, restricted range of motion, and lack of eccentric forces, leading to discomfort and incomplete muscle utilization.
Innovation Solution
A push-up apparatus with a convex base and adjustable handle allows for natural rotation of wrists and forearms, increased range of motion, and the ability to move the apparatus during exercise, reducing stress on wrists and engaging more muscle groups through eccentric forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If hands are fixed at a fixed angle with forearms during push-up, then wrist stability is improved, but wrist stress and hyperextension pain increase
Solution Approach 1:
The patent applies the dynamics principle by allowing the hands, wrists, and forearms to rotate naturally during the push-up exercise rather than being fixed in a static position. The apparatus enables dynamic movement where the hands can rotate in and out, and the forearms can move freely, transforming the exercise from a static to a dynamic motion that reduces harmful wrist stress while maintaining stability.
Solution Approach 2:
The patent changes the parameter of wrist and forearm position from a fixed angle to a variable, natural rotation range. By allowing the hands to rotate through a range of motion rather than maintaining a fixed angle, the apparatus modifies the mechanical parameters of the exercise to eliminate hyperextension and reduce wrist stress while preserving exercise effectiveness.
2Stability of the object's composition
If hands are fixed to the surface during push-up, then exercise stability is improved, but range of motion and muscle engagement are limited
Solution Approach 1:
The patent applies dynamics by enabling the hands to rotate naturally during the push-up motion rather than being constrained to a fixed position. This dynamic movement allows the hands to move in and out, increasing the range of motion while maintaining exercise stability through the controlled rotation mechanism.
Solution Approach 2:
The patent introduces another dimension of movement by allowing rotational motion of the hands and forearms in addition to the vertical push-up motion. This adds a rotational degree of freedom that increases the overall range of motion and engages more muscle groups while preserving exercise stability.
3Device complexity
If conventional push-up exercise is performed with fixed wrist position, then exercise simplicity is improved, but muscle engagement and eccentric forces are insufficient
Solution Approach 1:
The patent applies the dynamics principle by introducing natural rotation of the hands and forearms during the push-up exercise. This dynamic movement engages additional muscle groups that remain inactive in conventional fixed-position push-ups, increasing the quantity of engaged muscles while maintaining exercise simplicity through the natural motion mechanism.
Solution Approach 2:
The patent applies the self-service principle by allowing the hands and forearms to rotate naturally during the exercise without requiring external intervention or complex mechanisms. The body's natural rotational movement is harnessed to engage more muscles, making the exercise more comprehensive while remaining simple to perform.

AI summary
The present invention provides for an exercise apparatus for assisting in performing a push-up exercise. The apparatus includes a base with a convex outer surface connected to the handle support structure and a handle. The convex outer surface of the base of the apparatus provides a user with a means to engage muscle groups not normally exercised during a conventional push-up exercise, through the action of continuously stabilizing their weight on the apparatus, and by providing a means to rotate the wrists during the exercise. The apparatus also provides a user with a means to perform the exercise at different widths and positions during the exercise, by repositioning (sliding or moving) the apparatus during the exercise, on an appropriate surface. The apparatus is also intended to be lightweight and compact enough to be transportable for activities such as jogging or running.
