Treadmill Lifting Structure Rotational Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treadmill lifting mechanisms are prone to damage due to the high weight-bearing capacity, leading to a short service life and structural instability.
Innovation Solution
A lifting structure for a treadmill comprising a first unit and a second unit that are rotatably fitted together, allowing the treadmill platform to be rapidly lifted by rotating the second unit, thereby distributing the weight more evenly and reducing stress on individual components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bolt fixing method is used to adjust the inclination angle of the treadmill platform, then the climbing exercise function can be achieved, but the bolt is easily damaged due to high weight-bearing capacity, resulting in short service life
Solution Approach 1:
The lifting mechanism is divided into multiple components: a lifting assembly with lifting arms, a rotating assembly with rotating arms, and a connecting assembly. This segmentation distributes the weight-bearing load across multiple components rather than concentrating it on a single bolt, thereby improving reliability and service life while maintaining the climbing exercise function.
Solution Approach 2:
The patent employs dynamic lifting mechanisms where the lifting arms and rotating arms can rotate and adjust angles dynamically. This dynamic structure allows the system to adapt to different weight loads and operating conditions, distributing stress more effectively compared to static bolt fixing, thus extending service life while preserving exercise functionality.
2Adaptability or versatility
If a bolt fixing method is used to adjust the inclination angle, then the climbing exercise function is achieved, but the overall weight is mainly borne by the bolt, causing structural instability
Solution Approach 1:
The structural load is segmented and distributed across multiple components including lifting arms, rotating arms, and connecting assemblies. This distributed structure prevents any single component from bearing the entire weight, thereby improving structural stability while maintaining the ability to provide climbing exercise functionality.
Solution Approach 2:
The patent combines multiple functional components (lifting assembly, rotating assembly, connecting assembly) into an integrated system that works together to support the platform. This merging of components creates a more stable structural system that can handle the overall weight more effectively than isolated bolt fixing, while still enabling the climbing exercise function.
3Adaptability or versatility
If a lifting mechanism is added to achieve climbing exercise function, then the exercise versatility is improved, but the device complexity increases
Solution Approach 1:
The lifting mechanism is designed with multi-functionality, where the lifting arms, rotating arms, and connecting assemblies serve multiple purposes: supporting the platform weight, enabling inclination adjustment, and providing the climbing exercise function. This universality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while achieving exercise versatility.
