Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Performing push-ups with traditional parallel-handled bars exacerbates shoulder and wrist injuries due to excessive strain on the rotator cuff, shoulder joint, and surrounding muscles, particularly for individuals with pre-existing shoulder issues.

Innovation Solution

A push-up apparatus with handles angled to match the user's body orientation, allowing adjustable angles between the handles and vertical support members to reduce strain on the wrist and shoulder joints.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional parallel-handled bars are used for push-ups, then the exercise can be performed with standard equipment, but excessive strain is placed on the rotator cuff and shoulder joint causing injury

Engineering Contradiction:

Improveshoulder injury preventionVSAvoidproper form maintenance

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies asymmetry by positioning the handles at different heights rather than parallel orientations. The first handle is positioned at a first height and the second handle at a second height, creating an asymmetric configuration that aligns with the natural orientation of the user's body and arms during push-up exercise, thereby reducing strain on the rotator cuff and shoulder joint

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent transitions from a two-dimensional parallel handle configuration to a three-dimensional asymmetric configuration by positioning handles at different vertical heights. This dimensional change allows the handles to better match the spatial orientation of the user's arms and body, reducing harmful strain while maintaining exercise effectiveness

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If handles are positioned at non-nine0-degree angles to vertical support members, then strain on wrist and shoulder joints is reduced, but the device structure becomes more complex

Engineering Contradiction:

Improvejoint strain reductionVSAvoidhandle configuration

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by modifying the angular orientation of the handles relative to the vertical support members. Instead of using standard ninety-degree angles, the handles are positioned at non-nine0-degree angles that better align with natural body mechanics during push-up exercise, thereby reducing strain on the wrist and shoulder joints

AI summary

An apparatus allowing a user to perform a push-up exercise with a hand grip orientation that is similar to the user body orientation, comprising: a first handle configured to connect to a first vertical support member; a first horizontal support member configured to connect to the first vertical support member; a second handle configured to connect to the second vertical support member; and a second horizontal support member configured to connect to the second vertical support member. The first handle is configured such that when connected to the first vertical support member the angle between the first handle and the first vertical support member is not ninety degrees. The second handle is configured such that when connected to the second vertical support member the angle between the second handle and the second vertical support member is not ninety degrees.
