Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current medical systems require patients with benign paroxysmal positional vertigo (BPPV) to visit hospitals for immediate and accurate diagnosis and treatment, which is inconvenient and costly due to the high recurrence rate of symptoms, making self-diagnosis and treatment challenging.

Innovation Solution

A device and method for self-diagnosis and treatment of BPPV using a multi-step questionnaire system that allows patients to diagnose and treat themselves through a web-based service, including a data transmitting unit, data receiving unit, and control unit that determine final diagnosis information based on user responses, providing optimal treatment methods in the form of videos for specific BPPV types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If patients visit hospitals for BPPV diagnosis and treatment, then diagnostic accuracy and treatment effectiveness are improved, but time consumption and medical costs increase

Engineering Contradiction:

Improvediagnostic accuracyVSAvoidtime consumption

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system enables patients to perform self-diagnosis and self-treatment for BPPV through a web-based platform. Patients complete questionnaires about their symptoms, and the system automatically analyzes responses to determine BPPV type and provide personalized repositioning maneuver instructions, eliminating the need for hospital visits while maintaining diagnostic accuracy

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The web-based system acts as an intermediary between patients and medical professionals. It collects patient symptom data, applies diagnostic algorithms, and delivers treatment instructions, serving as a bridge that provides hospital-quality diagnosis without requiring physical presence at the hospital

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If patients visit hospitals for BPPV diagnosis and treatment, then diagnostic accuracy is improved, but medical costs increase

Engineering Contradiction:

Improvediagnostic accuracyVSAvoidmedical costs

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system replaces expensive hospital resources (medical equipment, professional time) with a low-cost web-based questionnaire system. The digital platform provides hospital-quality diagnosis at a fraction of the cost, making healthcare accessible without financial burden

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Measurement precision

If medical devices and faculty are used for BPPV diagnosis, then diagnostic accuracy is improved, but device complexity and operational difficulty increase

Engineering Contradiction:

Improvediagnostic accuracyVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical medical devices (video-oculography equipment, positional testing apparatus) with a software-based questionnaire system. The web platform uses algorithmic analysis of patient responses to achieve diagnostic accuracy previously requiring sophisticated medical equipment

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a digital replica of the hospital diagnosis process. Instead of using physical medical devices, it captures essential diagnostic information through structured questions and applies computational algorithms to reproduce the diagnostic decision-making process that previously required medical professionals and equipment

Inventive Principle:

Principle #26Copying

4Reliability

If medical faculty perform positional and repositioning maneuvers, then treatment effectiveness is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables patients to perform self-treatment through repositioning maneuvers. The web platform provides step-by-step visual instructions with videos and images, allowing patients to correctly perform Epley maneuver, Semont maneuver, or other repositioning techniques at home without professional assistance

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The web-based system acts as an intermediary that translates complex medical procedures into patient-friendly instructions. It receives diagnostic information, determines appropriate treatment protocols, and delivers simplified step-by-step guidance that bridges the gap between professional medical knowledge and patient self-execution

Inventive Principle:

Principle #24Intermediary (Mediator)
