Foldable Treadmill Structure With Auto-Lifting Incline
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fitness equipment often requires adjustable incline angles for varying training intensities but occupies significant space when extended horizontally.
Innovation Solution
A foldable structure with an automatically lifting slope, comprising a base frame, support frame, workbench, and telescopic rod, allows the workbench to be folded and adjusted to different incline angles using a telescopic rod that pulls and pushes the support frame to swing upwards, supported by limit portions and a handrail assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the workbench is extended horizontally to provide adequate working space, then the working area is improved, but the space occupied during storage increases
Solution Approach 1:
The workbench is designed with dynamic folding capability, allowing it to transition between extended horizontal position for working and folded vertical position for storage. The support frame can swing between horizontal and vertical positions, and the workbench can fold along predetermined lines, enabling the structure to adapt its configuration based on whether it is in use or storage mode.
Solution Approach 2:
The workbench is designed to fold and nest within a compact vertical configuration when not in use. The work surface can be folded down and stored within the frame structure, allowing the equipment to occupy minimal space during storage while maintaining full working dimensions when deployed.
2Adaptability or versatility
If the incline angle is adjusted manually to achieve different training intensities, then the adaptability is improved, but the ease of operation deteriorates
Solution Approach 1:
The incline angle adjustment system is designed to automatically adjust the workbench inclination based on the position of the support frame. As the support frame swings to different positions, the workbench inclination adjusts automatically without requiring manual intervention, making the system self-regulating and easy to operate.
Solution Approach 2:
The linkage mechanism between the support frame and workbench creates a dynamic relationship where changing the support frame position automatically changes the workbench inclination. This dynamic coupling allows users to adjust incline angles simply by moving the support frame, eliminating complex manual adjustment mechanisms.
3Ease of operation
If the workbench is designed to fold and stand up automatically, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The folding and standing up functions are merged into a single integrated mechanism. The support frame and workbench are connected through pivot points and linkages that combine the folding motion and inclination adjustment into one coordinated system, reducing the need for separate mechanisms for each function.
Solution Approach 2:
The mechanism uses dynamic linkages and pivot points that automatically coordinate the folding and standing up motions. As the support frame swings, the workbench automatically folds and adjusts its inclination through the interconnected linkages, creating a self-coordinating system that reduces mechanical complexity.
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 the workbench to be efficiently folded and adjusted to different incline angles, reducing space occupation and facilitating easy conversion between use and storage positions.
Implementation Method 1
The telescopic rod is capable of pulling the workbench to move forwards and drive the rear portion of the support frame to swing upwards, thus supporting the front portion of the workbench, and after extending, the telescopic rod is capable of pushing against the rear portion of the workbench to swing upwards
Implementation Method 2
A front portion of the support frame is pivoted on the base frame via the first rotating shaft extending left and right, and a rear portion of the support frame is arranged movably. A front portion of the workbench is pivoted at the rear portion of the support frame via a second rotating shaft extending left and right
