Solution Overview

Problem

Current orthopedic braces lack effective monitoring and feedback mechanisms to ensure proper use and progress tracking for patients with ACL or collateral ligament injuries, limiting the ability of healthcare providers to manage post-surgical care and rehabilitation effectively.

Innovation Solution

A brace with integrated remote patient monitoring technology, including a potentiometer and various sensors, that tracks and reports patient mobility and activity data to both patients and healthcare providers, enabling virtual therapy and proactive support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a brace is equipped with integrated remote patient monitoring technology including potentiometers and sensors, then patient mobility and activity data can be tracked and reported in real-time, but device complexity increases

Engineering Contradiction:
Improvepatient mobility and activity dataVSAvoidbrace structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines multiple monitoring functions (potentiometer for angular orientation, accelerometers for motion detection, gyroscopes for rotational movement) into a single integrated control unit within the brace. This merging of sensors and processing capabilities allows comprehensive patient mobility tracking while consolidating complexity into a centralized module rather than distributed components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control unit acts as an intermediary between the physical brace structure and the digital monitoring system. It processes raw sensor data from potentiometers and motion sensors, converts mechanical movements into digital signals, and manages wireless communication with external devices, thereby mediating between the simple mechanical brace and the complex monitoring requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If real-time monitoring and feedback mechanisms are implemented in the brace, then patient engagement and post-surgical care management improve, but device complexity and cost increase

Engineering Contradiction:
Improvepost-surgical care managementVSAvoidmonitoring system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements continuous feedback loops where sensor data from the brace is processed by the control unit and transmitted to external devices for real-time monitoring. This feedback mechanism allows healthcare providers to track patient compliance with rehabilitation protocols, detect abnormal movements, and intervene promptly, thereby improving care reliability through data-driven decision-making.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The brace enables patients to self-monitor their own recovery progress through the integrated system. Patients can view their own mobility data, compliance metrics, and recovery milestones through connected devices, allowing them to take active responsibility for their rehabilitation without requiring constant professional oversight, thus improving reliability through patient empowerment.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If multiple sensors and transducers are integrated into the brace for comprehensive monitoring, then measurement precision of joint motion improves, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvejoint motion and angular orientationVSAvoidbrace assembly
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The monitoring system is segmented into distinct functional modules: potentiometers for angular measurement, accelerometers for linear motion detection, and gyroscopes for rotational tracking. Each sensor type is independently positioned at strategic locations on the brace to capture specific movement parameters, allowing for precise joint motion measurement while enabling modular manufacturing and assembly of specialized components.

Inventive Principle:
Principle #1Segmentation
