Solution Overview

Problem

Users face difficulties in performing exercises correctly without expert guidance, as they struggle to maintain proper posture, and existing electronic devices fail to effectively capture and provide feedback on their posture during exercises.

Innovation Solution

An electronic device that can move to a designated or determined location to photograph the user, providing both a guide image and a user image for comparison, allowing users to assess their posture accurately.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the electronic device photographs the user at a fixed location, then the device structure is simple, but the user cannot properly photograph the desired body part or posture at the desired location

Engineering Contradiction:
Improveability to photograph user at desired locationVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The electronic device transitions from a static fixed-location camera to a mobile device that can move to different positions. The device includes a moving mechanism that allows it to relocate to designated positions around the user, enabling photography from multiple angles and locations as needed for exercise posture assessment.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the user photographs their own posture, then no expert guidance is needed, but the user cannot recognize whether their posture is correct or which part is incorrect

Engineering Contradiction:
Improveposture assessment accuracyVSAvoiduser ability to self-assess
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system creates a virtual copy of the user's posture by generating a two-dimensional image from the captured three-dimensional posture data. This virtual image is then overlaid on the user's actual posture, allowing the user to visually compare and identify discrepancies between their posture and the correct exercise form.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system provides immediate visual feedback by overlaying the generated posture image on the user's actual posture in real-time or near-real-time. This feedback mechanism allows users to see which body parts are positioned incorrectly and make immediate corrections without requiring expert interpretation.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If multiple cameras are used to capture user posture from different locations, then posture assessment accuracy improves, but device complexity and cost increase

Engineering Contradiction:
Improveposture capture accuracyVSAvoidnumber of cameras
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Instead of using multiple static cameras simultaneously, the system employs a single mobile camera that moves to different designated positions around the user. This dynamic approach captures images from multiple angles sequentially, achieving the same measurement precision as multiple cameras would provide, but with reduced device complexity and cost.

Inventive Principle:
Principle #15Dynamics
