Vibration Damping Assembly for Treadmill Slope Adjustment

Solution Overview

Problem

Current treadmills experience significant shaking during slope adjustment, which damages user joints and shortens the lifespan of lifting motors, necessitating a solution to mitigate this vibration.

Innovation Solution

An electric lifting slope adjustment device with a vibration damping function, incorporating a rotating shaft, lifting supports, a driving component with a lifting motor and rod, and a vibration damping assembly featuring a vibration damping spring or block, which absorbs and counteracts the shaking through elastic deformation, thereby stabilizing the running platform during adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a lifting mechanism is used to adjust the slope of the running platform, then the slope adjustment function is achieved, but shaking and vibration occur during the lifting process

Engineering Contradiction:

Improveslope adjustment functionVSAvoidshaking and vibration during lifting

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

A vibration damping assembly is introduced as an intermediary component between the lifting mechanism and the running platform. This assembly includes damping elements that absorb and dissipate vibration energy, thereby reducing the shaking transmitted to the running platform while preserving the slope adjustment functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The vibration damping assembly is pre-installed in the lifting mechanism to provide cushioning against upcoming vibrations. By anticipating and preparing for the vibration forces that will occur during slope adjustment, the system can mitigate these effects before they fully impact the running platform and user.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Device complexity

If the lifting mechanism operates without vibration damping, then the structure remains simple, but the shaking damages user joints and affects motor service life
