Leg Exercise Apparatus With Foot-Pulled Pivotable Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exercise apparatuses for strengthening leg muscles do not incorporate a pivotable lever attached to a weight support that is fixedly coupled to a weight, allowing users to engage their feet to perform resistance exercises effectively.
Innovation Solution
An exercise apparatus with a pivotable lever fixedly coupled to a weight support, enabling users to pull the lever towards their chest using their feet, which is coupled to a weight support configured to hold weights, and includes a foot engagement member for secure foot engagement and a platform that slides forwardly and rearwardly on a base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pivotable lever is fixedly coupled to a weight support and configured to be pulled toward the user's chest using feet, then resistance exercise effectiveness is improved, but device complexity increases
Solution Approach 1:
The exercise apparatus is divided into distinct functional segments: a base providing stability, a platform for user positioning, a weight support for holding resistance, and a pivotable lever with foot engagement members. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability despite the multiple moving parts.
Solution Approach 2:
The lever is designed to be pivotable rather than fixed, allowing dynamic movement during the exercise motion. The lever rotates about a pivot point on the base, enabling the foot engagement members to move through an arc as users pull toward their chest. This dynamic design accommodates the full range of motion required for effective resistance training while maintaining mechanical advantage.
2Adaptability or versatility
If the weight support is spaced forwardly of the platform, then the range of motion is altered to target different muscle groups, but the device complexity increases
Solution Approach 1:
The forward positioning of the weight support relative to the platform serves multiple functions: it creates the necessary moment arm for effective resistance, establishes the pivot point for lever rotation, and defines the arc of motion for foot engagement. This single design decision achieves both mechanical advantage and versatile muscle targeting without requiring additional adjustable components.
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 effective resistance exercises by allowing users to engage their feet to lift weights, accommodating various user heights and altering the range of motion to target different muscle groups effectively.
Implementation Method 1
A lever is fixedly coupled to the weight support and pivotally coupled to the base
Implementation Method 2
The weight support is pivotally coupled to the base and is spaced forwardly of the platform with respect to the base. The weight support is shaped such that the weight support is configured to support a weight.
