Adjustable Stool Inclination for Calf Raise Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing standing squat calf raise machines do not effectively vary the inclination of the stool on which the user stands, limiting exercise efficiency and muscle engagement.
Innovation Solution
A standing squat calf raise machine with a frame unit, load application unit, and stool unit that allows for adjustable inclination of the stool surface, enabling users to lift or lower a load while placing their feet flat on the floor, and includes operational rotation units to facilitate varying the angle of the stool and load application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stool inclination is fixed, then the device structure is simple, but the exercise efficiency cannot be optimized for different muscle groups
Solution Approach 1:
The stool unit is designed with adjustable inclination capability, transforming from a static structure to a dynamic one. The stool can be adjusted to different angles (0 degrees, 30 degrees, 45 degrees) to target different muscle groups, allowing the same device to adapt to various exercise requirements without changing the overall device structure
Solution Approach 2:
The inclination angle of the stool is changed as a variable parameter to achieve different exercise effects. By adjusting the angle parameter, users can target different calf muscle groups (gastrocnemius vs. soleus), thereby optimizing exercise efficiency without adding complex functional components
2Adaptability or versatility
If the stool inclination is adjustable, then the exercise efficiency is improved, but the device complexity increases
Solution Approach 1:
The stool unit is segmented into adjustable components that can be independently positioned at different angles. The stool frame includes multiple positioning points and adjustment mechanisms that allow incremental angle changes, breaking down the complex adjustment function into manageable segments
Solution Approach 2:
The adjustable stool mechanism serves multiple functions: it provides different inclination angles for targeting different muscle groups, maintains structural stability during exercise, and integrates seamlessly with the existing frame and load application unit, making one component perform multiple roles

AI summary
As for the standing squat calf raise according to an embodiment of this invention, the inclination of the stool where the user stands to perform an action of lifting or lowering a load toward the floor is varied while placing his or her feet flat on the floor. It shall include a frame unit forming a mounting space with multiple frames connected to the frame unit above to be rotatable, and it shall mediate the load application unit for applying a load in the direction of the floor, a stool unit formed on the lower part of the front side of the frame unit to provide a space for the user to step on, load application unit, and the frame unit to include a operational mounting unit to allow for the load application unit to be held at a certain height. In addition, the stood unit may change the inclination of the surface on which the user steps on by varying the height of one side of the rear.
