Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for diagnosing and treating swallowing disorders are limited by high costs, lack of portability, and insufficient accessibility, leading to suboptimal treatment and limited access to therapy, especially for patients in remote areas, and existing systems do not provide meaningful feedback to patients, affecting adherence and motivation.
Innovation Solution
A portable system comprising a computing device and a wearable measurement device that transmits sEMG or MMG data, providing visual and audible feedback, and incorporating game design principles to enhance patient engagement and adherence, allowing remote monitoring and data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sEMG biofeedback systems are used for swallowing therapy, then treatment effectiveness is improved, but cost and device complexity increase, making them inaccessible to many clinical units and patients
Solution Approach 1:
The patent uses a microphone to capture acoustic signals that copy or represent the mechanical oscillations of muscle contractions during swallowing. Instead of using complex sEMG sensors, the system creates an acoustic copy of the muscle activity through the MMG effect, processing these signals to provide biofeedback equivalent to traditional sEMG systems but at much lower cost and complexity
Solution Approach 2:
The patent replaces the mechanical/electrical sEMG sensing system with an acoustic measurement system. By substituting the mechanical sensor-based approach with an acoustic field-based approach (using a microphone to detect sound waves generated by muscle contractions), the system achieves similar therapeutic functionality while dramatically reducing device complexity and cost
2Reliability
If clinician-supervised therapy models are used, then treatment quality is maintained, but accessibility and availability of therapy decrease due to limited clinical capacity
Solution Approach 1:
The patent enables patients to perform swallowing therapy independently at home using the portable device. The system provides automated biofeedback through the mobile application, allowing patients to self-monitor and self-correct their swallowing patterns without requiring constant clinician supervision. The device guides patients through exercises and provides real-time feedback, making high-quality therapy accessible outside the clinical setting
Solution Approach 2:
The system incorporates real-time biofeedback through the mobile application, providing patients with immediate information about their swallowing muscle activity. This feedback loop enables patients to self-correct and improve their swallowing patterns independently, maintaining treatment quality without requiring continuous clinician presence. The feedback mechanism bridges the gap between professional supervision and home-based self-management
3Reliability
If intensive exercise programs with sEMG biofeedback are implemented, then swallowing function improves, but patient motivation and adherence decrease due to lack of meaningful feedback
Solution Approach 1:
The patent provides patients with real-time visual and audible feedback about their swallowing muscle activity through the mobile application. The system displays waveforms, provides auditory cues, and gives immediate feedback on whether the patient is performing exercises correctly. This meaningful feedback makes the therapy engaging and helps patients understand their progress, significantly improving motivation and adherence to the intensive exercise program
Solution Approach 2:
The mobile application uses visual displays showing waveforms and signal variations to provide feedback to patients. By transforming the invisible muscle contractions into visible graphical representations, the system makes the therapy experience more engaging and provides patients with intuitive feedback about their performance, enhancing motivation and adherence
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables cost-effective, accessible, and motivating therapy for swallowing disorders, improving patient adherence and quality of life by providing meaningful feedback and remote monitoring, reducing the burden on both patients and the healthcare system.
Implementation Method 1
MMG can make use of a sensor capable of measuring mechanical oscillations originating from muscle contractions to sense muscle contractions
Implementation Method 2
sEMG has been the main technology used for biofeedback in swallowing disorders
Data Source
AI summary
A system is provided for monitoring patients with dysphagia, or swallowing impairments, that monitors muscle movement during intensive swallowing exercises to provide adjuvant visual feedback from surface electromyography.
