Solution Overview

Problem

Traditional treadmills driven by motors consume large amounts of electricity, generate loud noise, and have high costs, while requiring long adjustment times for speed changes, failing to meet user demands for rapid adjustments.

Innovation Solution

A treadmill design featuring a driving piece, supporting piece, and border structure that converts a shorter translation stroke of the driving piece into a longer rotating stroke of the supporting piece, allowing for rapid adjustments with reduced energy consumption and noise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a motor is used to drive the treadmill, then the speed adjustment can be achieved, but the energy consumption increases and noise is generated

Engineering Contradiction:
Improvespeed adjustment capabilityVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The patent removes the motor from the treadmill system entirely, extracting the harmful energy-consuming and noise-generating component while retaining the speed adjustment function through a mechanical driving piece that converts rotational motion to linear motion of the running platform

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the electrical motor-driven system with a pure mechanical system using a driving piece that translates rotational input into linear displacement of the running platform, eliminating the need for continuous electrical power during operation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Speed

If a motor is used to drive the treadmill, then the speed adjustment can be achieved, but the noise increases

Engineering Contradiction:
Improvespeed adjustment capabilityVSAvoidnoise
Core Design Contradiction:
SpeedVSObject-generated harmful factors

Solution Approach 1:

The patent removes the motor from the treadmill system entirely, extracting the harmful noise-generating component while retaining the speed adjustment function through a mechanical driving piece that operates silently through pure mechanical motion

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the electrical motor-driven system with a pure mechanical system using a driving piece that translates rotational input into linear displacement of the running platform, eliminating the noise associated with motor operation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If a traditional adjustment mechanism is used, then the slope can be adjusted, but the adjustment time is long

Engineering Contradiction:
Improveslope adjustmentVSAvoidadjustment time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent implements a dynamic adjustment mechanism where the driving piece can rapidly change the position of the running platform by converting rotational motion into linear displacement, allowing quick slope adjustments without the delays of traditional mechanical systems

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent enables rapid change of the running platform's position parameter through the driving piece mechanism, which can quickly translate between different slope configurations, reducing adjustment time from traditional slow mechanical systems

Inventive Principle:
Principle #35Parameter changes

4Length of moving object

If a longer stroke is required for adjustment, then the adjustment range is improved, but the adjustment time increases

Engineering Contradiction:
Improveadjustment strokeVSAvoidadjustment time
Core Design Contradiction:
Length of moving objectVSLoss of time

Solution Approach 1:

The patent uses the driving piece to dynamically convert a short rotational stroke into a longer linear displacement stroke of the running platform, achieving both long adjustment range and rapid adjustment through the mechanical advantage of the translation mechanism

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent transforms the motion from one dimension (rotational stroke of the driving piece) to another dimension (linear displacement of the running platform), converting a short rotational movement into a longer linear adjustment stroke through the supporting piece mechanism

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

AI summary

Provided is a treadmill, including a running platform. The running platform 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.
