Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing exercise devices do not adequately support stable single or double leg squatting, particularly for individuals with spinal conditions or reduced flexibility, leading to compromised mobility and increased susceptibility to injuries due to improper biomechanics and lack of spinal range of motion during squat exercises.

Innovation Solution

A squat exercise device with a base frame, foot support, vertical and horizontal stabilization bars, and lower leg support braces that provide stability and allow for spinal flexibility without compressive loads, enabling proper squat mechanics and enhancing balance, coordination, strength, and endurance of lower leg, knee, hip, pelvis, and spine regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing exercise devices are used for squat exercises, then basic exercise function is provided, but stable lower extremity support and proper spinal alignment are not adequately achieved

Engineering Contradiction:

Improvestability of lower extremities during squatVSAvoidstructural complexity of exercise device

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The device is divided into separate functional components: a base for foot placement, vertical stabilization bars for lateral support, horizontal stabilization bars for anterior-posterior stability, and lower leg support braces for positional control. This segmentation allows each component to address specific stability requirements independently, achieving reliable lower extremity support without excessive overall complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device adds vertical and horizontal stabilization bars that extend in multiple dimensions from the base, creating a three-dimensional stabilization framework. This multi-dimensional approach provides comprehensive support for lower extremity stability during squat exercises, addressing limitations of conventional two-dimensional exercise equipment.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If traditional squat exercises are performed without specialized support, then exercise simplicity is maintained, but improper biomechanics and spinal compression occur

Engineering Contradiction:

Improvesimplicity of squat exerciseVSAvoidspinal compression and improper biomechanics

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The stabilization bars and support braces act as intermediary structures between the user's body and the ground, providing mechanical guidance and support. These intermediaries ensure proper biomechanical alignment during squat exercises by preventing excessive lateral movement, forward lean, or knee collapse, thereby eliminating harmful spinal compression while maintaining exercise simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The device applies preliminary stabilizing forces through the vertical and horizontal bars before improper biomechanics can occur. The lower leg support braces pre-position the lower extremities in correct alignment, preventing harmful movements before they happen during the squat exercise, thus protecting against spinal compression while keeping the exercise simple to perform.

Inventive Principle:

Principle #9Preliminary anti-action

3Object-affected harmful factors

If spinal range of motion is restricted during squat, then spinal compression is reduced, but flexibility and coordination development are compromised

Engineering Contradiction:

Improvespinal compression during squatVSAvoidspinal flexibility and coordination

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The device provides dynamic stabilization rather than rigid restriction. The vertical and horizontal stabilization bars allow controlled movement within safe boundaries, adapting to the user's natural range of motion while preventing harmful positions. This dynamic approach reduces spinal compression by guiding proper alignment while simultaneously allowing sufficient flexibility and coordination development through controlled movement variability.

AI summary

An exercise device including a frame extending across a first plane, the frame defining vertical stabilization bars extending in a second plane, the frame further defining a horizontal cross bar connecting the vertical stabilization bars and configured for supporting a lower leg of a user. A swivel base couples to the frame for supporting a foot of the user. The swivel base may be fixed in a variety of positions as well as set to somewhat freely rotate while coupled to a bias spring.
