Solution Overview

Problem

Traditional medical instruments, such as otoscopes and speculums, are unsuitable for remote medical examinations like teleconsultations, particularly for examining oral cavities, auditory canals, nasal cavities, and skin conditions, as they are not adapted for remote image acquisition and transfer.

Innovation Solution

A device comprising a cell phone or imaging device equipped with a removable sighting head of varying profiles and optical systems, allowing for image capture and transfer of images from cavities or skin areas to medical professionals for remote consultations, featuring a support with a fixing base and optional endoscopic parts for improved illumination and magnification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional medical instruments (otoscope, speculum) are used for examination, then the examination function is achieved, but the instruments are unsuitable for teleconsultations and remote image acquisition

Engineering Contradiction:
Improveadaptability to teleconsultationVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines traditional medical examination instruments with modern digital imaging technology (smartphone camera, LED lighting, magnifying lenses) to create an integrated telemedicine device. The smartphone is mounted within a housing that contains optical components, creating a unified system that performs both traditional examination and digital image capture functions simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device is designed to perform multiple functions: it can examine various body cavities (ear, nose, throat) using different interchangeable speculums, capture high-quality images with integrated lighting and magnification, and transfer images remotely via smartphone connectivity. This multi-functional design makes it suitable for both traditional examination and teleconsultation purposes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a fixed examination device is used, then the device structure is simple, but it cannot adapt to different body areas and patients

Engineering Contradiction:
Improveadaptability to different body areasVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into modular components: a main housing containing the smartphone and optical system, and interchangeable speculums tailored for different body cavities (ear speculum, nasal speculum, oral speculum). This segmentation allows the user to keep the main unit simple while adapting to different examination needs through component replacement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device incorporates adjustable elements including variable magnification lenses that can be switched to change the level of magnification, and interchangeable speculums that allow the examination area to be dynamically adapted. The smartphone's camera and lighting system can also be adjusted to optimize image capture for different anatomical structures.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If traditional instruments are used, then the equipment is simple, but image capture and transfer for remote consultation is not possible

Engineering Contradiction:
Improveimage transfer capabilityVSAvoiddevice complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The smartphone acts as an intermediary device that bridges the traditional examination function and the digital image transfer function. The integrated camera system captures images through the optical components, and the smartphone's processing and communication capabilities enable remote transmission of these images to healthcare providers or electronic health records.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical examination-only instruments with a system that incorporates electronic imaging and digital communication capabilities. The optical system (lenses, mirrors, lighting) works in conjunction with the smartphone's digital sensor and wireless communication modules to substitute pure mechanical examination with a hybrid opto-electronic system that enables both local and remote diagnosis.

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