Treadmill Lifting Structure with Rotating Folded Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treadmill lifting structures occupy too much space when folded, making them unsuitable for treadmills with low ground clearance.
Innovation Solution
A lifting structure for a treadmill platform with lifting units that rotate and fold inwards, occupying only the thickness of the first wall in the height direction, allowing for a lower profile when stored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional lifting structure is used to enable climbing exercise function, then the lifting function is achieved, but the ground clearance increases and the overall height of the treadmill increases
Solution Approach 1:
The lifting unit is designed to nest within the support frame when folded, with the lifting plate containing the support rod and both being storable within the frame structure. This nesting arrangement allows the lifting mechanism to be compact when not in use, minimizing the ground clearance and overall height of the treadmill while maintaining the climbing exercise function when deployed.
Solution Approach 2:
The lifting unit transitions from a two-dimensional flat configuration when folded to a three-dimensional extended configuration when in use. The lifting plate rotates from a horizontal position (storing within the frame) to a vertical position (providing climbing function), effectively utilizing spatial transformation to resolve the contradiction between compact storage and functional deployment.
2Adaptability or versatility
If the lifting unit is designed to provide climbing exercise function, then the lifting capability is achieved, but the space occupation in height direction increases
Solution Approach 1:
The lifting plate is designed to contain the support rod within its structure, and both components can be stored within the frame when not in use. This nested configuration minimizes the height occupation to only the thickness of the lifting plate when folded, while providing full lifting capability when deployed.
Solution Approach 2:
The lifting unit employs rotational movement to transition between a compact horizontal position (minimizing height) and an extended vertical position (providing lifting capability). This dynamic transformation allows the same structure to serve both space-saving and functional requirements at different times.
