Solution Overview

Problem

Conventional treadmills with single-layer support frames are ineffective in eliminating noise vibrations during running, causing disturbance to neighbors downstairs.

Innovation Solution

A multi-layer frame structure is implemented, comprising at least one first frame and one second frame, with first and second elastic shock-absorbing members mounted between and under the frames respectively, to absorb and dampen vibrations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single-layer support frame structure is used, then the device complexity is reduced, but the noise elimination effect is limited causing disturbance to neighbors

Engineering Contradiction:

Improveframe structureVSAvoidnoise vibration

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The support frame is segmented into multiple layers (first frame and second frame) with shock-absorbing members positioned between them. This segmentation allows the vibration damping function to be distributed across multiple components, effectively reducing noise transmission to downstairs areas while maintaining structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Elastic shock-absorbing members are introduced as intermediary elements between the first frame and second frame. These intermediaries absorb and dampen vibration energy, preventing direct transmission of noise to the building structure and downstairs neighbors, thus resolving the contradiction between simple structure and noise control.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a multi-layer frame structure with elastic shock-absorbing members is used, then the noise elimination effect is improved, but the device complexity increases

Engineering Contradiction:

Improvenoise vibrationVSAvoidframe structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The elastic shock-absorbing members serve multiple functions: they act as structural connectors between frames, vibration dampers, and noise isolators. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving effective noise elimination.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If elastic shock-absorbing members are mounted between frames, then vibration damping is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improvevibration dampingVSAvoidassembly process

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The elastic shock-absorbing members are pre-mounted between the first and second frames during the assembly process. This preliminary action ensures proper positioning and pre-compression of the damping elements, improving vibration damping reliability while actually simplifying the overall manufacturing process by avoiding the need for complex adjustment mechanisms during installation.

Inventive Principle:

Principle #10Preliminary action
