Solution Overview

Problem

Novice or casual users lack the knowledge and ability to correctly perform exercise routines on exercise machines, and many cannot afford personal trainers or gym memberships for skilled monitoring.

Innovation Solution

An interactive exercise system with a mirrored display, force-controlled components, and biometric sensors that provide real-time feedback and adjust resistance based on user position, force, and biometric data, allowing for personalized exercise programs and guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If exercise machines are used without skilled monitoring, then device accessibility is improved, but exercise performance correctness deteriorates

Engineering Contradiction:
Improvedevice accessibilityVSAvoidexercise performance correctness
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system incorporates sensors that detect user position, applied force, and biometric signals, providing real-time feedback through a display to guide users on correct exercise form and automatically adjust resistance levels, enabling novice users to perform exercises correctly without personal trainers

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The exercise machine autonomously monitors user performance through integrated sensors and automatically adjusts force resistance based on detected user input and biometric data, eliminating the need for external monitoring personnel while maintaining exercise correctness

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If personal trainers are hired for monitoring, then exercise performance correctness is improved, but cost increases

Engineering Contradiction:
Improveexercise performance correctnessVSAvoidcost
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The system incorporates sensors that detect user position, applied force, and biometric signals, providing real-time feedback through a display to guide users on correct exercise form and automatically adjust resistance levels, enabling novice users to perform exercises correctly without personal trainers

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of human personal trainers with an automated electronic system comprising sensors, processors, and display interfaces that monitor and guide exercise performance, thereby eliminating the need for expensive human monitoring while maintaining exercise correctness

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

3Productivity

If complex exercise routines are provided, then training effectiveness is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvetraining effectivenessVSAvoidease of operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system incorporates sensors that detect user position, applied force, and biometric signals, providing real-time feedback through a display to guide users on correct exercise form and automatically adjust resistance levels, enabling novice users to perform exercises correctly without personal trainers

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The force resistance is dynamically adjusted in real-time based on user performance and biometric feedback, allowing the system to adapt complex training protocols to the user's current capability level, making advanced training effective yet accessible to users of all skill levels

Inventive Principle:
Principle #15Dynamics

AI summary

An interactive exercise system includes a mechanical support system and a display module held by the mechanical support system. A mirror element is attached to at least partially cover the display module. At least one movable arm is connected to the support system and at least one force-controlled component is connected to the mechanical support system. The force-controlled component can be graspable by a user and allows for a range of exercise types and programs.
