Solution Overview

Problem

Users of treadmills, especially manual ones, face challenges in maintaining a consistent exercise speed, which can lead to injury or irregular exercise due to the lack of guidance on speed control, and automatic treadmills may force users to exercise at unsafe speeds if they cannot keep up.

Innovation Solution

An exercise guide system that includes an input unit for setting a target exercise speed, a detection unit to monitor actual speed, and an exercise guide unit that provides feedback to the user on the difference between target and actual speed, allowing users to adjust their speed based on visual, auditory, or tactile cues, enabling them to exercise at their desired pace.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automatic treadmills use a motor to control exercise speed, then exercise speed can be maintained at a constant target speed, but users may be injured when they cannot keep up with the target speed

Engineering Contradiction:

Improveexercise speed controlVSAvoiduser injury

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system continuously detects the user's actual exercise speed and compares it with the target exercise speed, then provides real-time feedback through visual, auditory, or tactile signals to guide the user to adjust their speed, resolving the contradiction between maintaining target speed and preventing injury

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The user personally adjusts their exercise speed based on the feedback provided by the system, rather than being forced by the motor, allowing them to control their own pace while still receiving guidance to meet exercise goals

Inventive Principle:

Principle #25Self-service

2Ease of operation

If manual treadmills allow users to control speed freely, then users can exercise at their own pace and prevent injury, but users have difficulty in exercising according to exercise goals

Engineering Contradiction:

Improvespeed control freedomVSAvoidexercise goal achievement

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system provides real-time feedback on the difference between actual and target exercise speeds, guiding users to adjust their pace to meet exercise goals while maintaining the freedom of manual speed control

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The exercise guide system acts as an intermediary between the user's free will and the exercise goals, providing information that helps users make informed decisions about their speed adjustments

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If the exercise guide system provides continuous feedback on speed difference, then users can maintain target exercise speed, but the system complexity increases

Engineering Contradiction:

Improvetarget speed maintenanceVSAvoidsystem structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system uses a detection unit to monitor actual speed and an exercise guide unit to provide feedback on the difference between actual and target speeds, achieving target speed maintenance through a relatively simple feedback mechanism

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system replaces complex mechanical speed control mechanisms with a simpler detection and information provision system, where the user's own actions control the treadmill while the system provides guidance information

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Provided is an exercise guide system. The exercise guide system guides a user in an exercise on a treadmill, of which the speed is controllable according to the user's free will. The exercise guide system includes an input unit configured to receive at least one target exercise speed, a detection unit configured to detect an actual exercise speed of the user on the treadmill. The exercise guide system further includes an exercise guide unit configured to provide information related to the actual exercise speed and the target exercise speed so that the user personally adjusts an exercise speed on the treadmill.
