Counterweight Lever Exercise Machine for Squat Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise apparatuses for lower body exercises can hinder proper form and are limited in the range of exercises they allow, making them inadequate for effective rehabilitation and strength training.
Innovation Solution
An exercise machine with a seat suspended from a lever biased towards an initial position, which assists users in performing lower body exercises like squats by reducing the load on the user's muscles, thereby improving form and range of motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional exercise apparatuses are used for lower body exercises, then exercise support is provided, but proper form is hindered and range of motion is limited
Solution Approach 1:
The seat is made dynamically movable along an arcuate path through the lever mechanism, allowing it to adapt to different positions and angles during exercise. This dynamic positioning enables users to achieve proper form while increasing range of motion, resolving the contradiction between ease of operation and adaptability
Solution Approach 2:
The exercise apparatus is designed to perform multiple lower body exercises including squats, lunges, and step-ups through the versatile lever and seat mechanism. This multi-functionality allows the same apparatus to support various exercises with different form requirements, simultaneously improving ease of operation and range of motion
2Strength
If conventional exercise apparatuses are used, then exercise support is provided, but load on user muscles is increased
Solution Approach 1:
The lever mechanism functions as a counterbalance system that offsets a portion of the user's body weight during exercise. By positioning the seat on the lever arm, the apparatus provides upward support force that reduces the effective load on user muscles, allowing for strength training with decreased force requirements
3Force
If a lever mechanism with biasing is used, then load on user muscles is reduced, but device complexity increases
Solution Approach 1:
A spring-loaded biasing mechanism provides counterbalancing force to reduce load on user muscles. The spring acts as a mechanical anti-weight system that automatically adjusts to support the user during exercise, reducing muscle load without requiring complex electronic controls or multiple actuators
Solution Approach 2:
The biasing mechanism automatically adjusts to the user's position and weight through the spring's inherent mechanical properties. The system self-regulates the support force based on the lever angle and user load, eliminating the need for complex control systems, sensors, or manual adjustments, thereby reducing overall device complexity

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 exercise machine assists users in performing lower body exercises with improved form and increased range of motion, reducing the physical effort required and allowing for more effective rehabilitation and strength training.
Implementation Method 1
The lever is biased toward an initial position... the lever is biased toward the first position... the seat is biased in an upward direction, thereby assisting the user while squatting by reducing load borne by muscles of the user

AI summary
An exercise apparatus including a base, a support extending from the base, a lever, at least one seat arm and a seat is disclosed. The lever, which is pivotally connected to the support about a first horizontal pivot axis, has first and second portions extending on, respectively, first and second sides of the first horizontal pivot axis. The at least one seat arm upper portion and lower portions connected to, respectively, the first portion and the seat. The seat is pivotally connected to the first portion about a second horizontal pivot axis, which is parallel to the first horizontal pivot axis, via the at least one seat arm. The lever selectively pivots about the first horizontal pivot axis between first and second positions, the seat being higher in the first position than in the second position, and the lever being biased toward the first position.
