Retractable Pad Assembly for Compact Glute Ham Developer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional glute ham and Nordic curl machines are bulky, difficult to move, and not scalable for users, making them inaccessible for most people who lack the strength and muscle control to perform these exercises unassisted.
Innovation Solution
An adjustable glute hamstring developer with a retractable pad assembly that slides under the main body, allowing the user to adjust the angle of the fitness pad to suit their fitness level, thereby making the exercise more accessible and scalable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional glute ham and Nordic curl machines are used, then the exercise can be performed with assistance, but the device takes up a large amount of space and is difficult to move
Solution Approach 1:
The pad assembly is designed to nest within the support base when not in use, with the lower bar and support bar storing inside the recessed portion of the support base. This nesting mechanism reduces the overall space occupied by the device while maintaining full functionality when the pad assembly is extended for exercise use.
Solution Approach 2:
The pad assembly incorporates movable and adjustable components including a pivotally coupled support bar and a retractable lower bar that can slide in and out of the support base. These dynamic elements allow the device to transition between a compact stored state and an extended exercise state, providing both space efficiency and operational ease.
2Ease of operation
If traditional glute ham and Nordic curl machines are used, then the exercise can be performed with assistance, but the device is heavy and stationary, making it not easily moveable
Solution Approach 1:
The device is divided into separate functional modules: a stationary support base and a movable pad assembly. The pad assembly with the lower bar and support bar can be independently retracted into the support base, allowing the main body to be lighter and more movable while maintaining the functional elements needed for exercise.
3Adaptability or versatility
If traditional glute ham and Nordic curl machines are used, then the exercise can be performed, but the device is not scalable for users with different fitness levels
Solution Approach 1:
The pad assembly features an adjustable angle mechanism that allows users to modify the inclination of the fitness pad according to their fitness level. This dynamic adjustability enables the same device to accommodate users ranging from beginners to advanced athletes without requiring multiple different devices or complex reconfiguration.
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
The device allows users to perform Nordic hamstring curls at their desired difficulty level without the need for additional props or bands, making the exercise more accessible and reducing the space and mobility issues associated with traditional machines.
Implementation Method 1
a support bar pivotally coupled to the lower bar
Implementation Method 2
the retractable pad assembly being slidably coupled to the support base between: a collapsed position wherein the lower bar and the support bar are disposed in the recessed portion; and an extended position wherein the lower bar and the support bar extend out of the recessed portion
