Treadmill Running Platform Linkage for Rapid Incline Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional treadmills driven by motors consume a lot of electricity, generate loud noise, have high costs, and require a long time for adjustments, making it difficult to meet the requirement of rapid adjustment by users.
Innovation Solution
The treadmill design includes a running platform with a driving piece, a supporting piece, and a border, where the driving piece drives the supporting piece to move, which in turn drives the border to move, effectively converting a shorter translation stroke of the driving piece into a longer rotating stroke of the supporting piece, allowing for rapid adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a motor is used to drive the treadmill, then the running platform can be moved, but energy consumption increases and noise is generated
Solution Approach 1:
The treadmill uses the user's own body weight and movement as the driving force. When the user steps on the running platform and moves, their weight automatically drives the supporting piece and border to adjust the platform's inclination angle, eliminating the need for motor-driven movement and reducing energy consumption.
Solution Approach 2:
The patent introduces a mechanical transmission mechanism consisting of a driving piece, supporting piece, and border as intermediaries. These components transmit and amplify the user's input force to achieve platform adjustment, replacing the direct motor-driven approach with a mechanical advantage system.
2Speed
If a motor is used to drive the treadmill, then the running platform can be moved, but noise is generated
Solution Approach 1:
The system uses the user's body weight and manual input as the primary driving force, eliminating or minimizing the need for motors. This mechanical self-service approach significantly reduces noise generation compared to motor-driven systems.
Solution Approach 2:
The patent replaces the motor-driven mechanical system with a user-driven mechanical system. By substituting motor power with human power through the driving piece and supporting piece mechanism, the noise-generating motor is eliminated while maintaining the platform movement capability.
3Ease of operation
If a traditional adjustment mechanism is used, then the running platform can be adjusted, but the adjustment time is long
Solution Approach 1:
The patent transforms the adjustment mechanism by introducing a rotational dimension through the supporting piece. The driving piece converts linear movement into rotational movement of the supporting piece, which in turn rotates the border to adjust the platform angle. This dimensional transformation enables faster adjustment compared to traditional linear mechanisms.
Solution Approach 2:
The system employs dynamic, movable connections between the driving piece, supporting piece, and border. These components can freely move and rotate during adjustment, allowing rapid response to user input. The dynamic nature of the mechanism enables quick adjustment without the delays associated with fixed or rigid adjustment systems.
4Length of moving object
If a longer translation stroke is used for adjustment, then the adjustment range is improved, but the adjustment time increases
Solution Approach 1:
The patent converts linear translation motion into rotational motion through the supporting piece. By introducing rotation as another dimension of movement, the system achieves a longer effective adjustment stroke without requiring a longer linear translation distance. The rotational amplification allows the driving piece to cover a shorter linear distance while still achieving the required platform angle adjustment range.
Solution Approach 2:
The dynamic rotational mechanism of the supporting piece allows for rapid angular adjustment. The rotation can occur quickly without the mechanical constraints of long linear strokes, enabling the system to achieve both long adjustment range and short adjustment time simultaneously through motion transformation.

AI summary
A treadmill, including a running platform, which includes a driving piece, a supporting piece and a border; the border is movably connected to the driving piece; the supporting piece is movably connected to the driving piece and is movably connected to the border; and the driving piece optionally drives the supporting piece to move to drive the border to move. In this way, a shorter translation stroke of the driving piece is converted into a longer rotating stroke of one end of the supporting piece through the supporting piece. Therefore, a stroke of the driving piece driving the running platform to move up and down can be enlarged, so that in a case that a longer stroke is required for adjustment, in-place adjustment can be achieved within a short time, and the requirement of rapid adjustment by a user can be met while energy consumption, noise and cost are reduced.
