Solution Overview

Problem

Existing treadmills pose accessibility issues for users with physical disabilities or limitations due to a height gap between the belt and floor, and safety concerns arise from the risk of falling off the belt surface.

Innovation Solution

A physical activity apparatus featuring a revolving belt with an elevated return belt surface, mounted on rollers, allowing the activity belt surface to remain substantially at floor level, reducing the height gap and enhancing safety through a never-ending loop configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the treadmill belt is elevated to provide a moving surface, then the treadmill can function as an exercise machine, but the height gap between the belt and floor increases making it hard to access for users with physical disabilities or elders

Engineering Contradiction:
Improvetreadmill functionalityVSAvoidaccessibility to belt surface
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention transitions from a traditional linear treadmill belt to a circular revolving belt configuration. By changing the spatial dimension and arrangement of the belt from a straight elevated surface to a circular loop with elevated return portion, the activity belt surface can be positioned at floor level while maintaining treadmill functionality through the circular motion path.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the treadmill belt is elevated to create a running surface, then the treadmill operates effectively, but the risk of falling off the belt increases creating safety hazards

Engineering Contradiction:
Improvetreadmill operationVSAvoidfalling risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By reconfiguring the belt into a circular revolving structure with the return portion elevated above the activity surface, the invention creates a contained motion path that reduces falling risk while preserving exercise functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The circular belt structure nests the activity belt surface within the larger circular loop, creating a contained exercise area where the elevated return portion acts as a protective barrier rather than a drop-off edge.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Device complexity

If a traditional treadmill belt configuration is used, then the structure is simple, but accessibility and safety are compromised due to the height gap

Engineering Contradiction:
Improvetreadmill structureVSAvoiduser accessibility
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The invention maintains relatively simple structural elements (frame, rollers, belt) while changing their spatial arrangement to a circular configuration. This dimensional change allows the activity surface to be at floor level without requiring complex additional mechanisms, preserving ease of access while improving safety.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
