Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standardized patients are used for auscultation training, then one-on-one interaction with real patients is provided, but most standardized patients do not have abnormal physical findings

Engineering Contradiction:

Improvetraining effectivenessVSAvoidsimulation of abnormal findings

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent uses audio recordings of abnormal body sounds (heart murmurs, lung sounds, etc.) as substitutes for actual abnormal physical findings. These audio copies are transmitted wirelessly to stethoscopes, allowing students to detect and identify abnormal sounds without requiring standardized patients to actually have those conditions.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

A wireless audio transmission system acts as an intermediary between the audio source (abnormal sound recordings) and the stethoscope. The transmitter and receiver system mediates the delivery of abnormal sound signals to the student's stethoscope, enabling the simulation of abnormal findings without direct physical modification of the patient or standardized person.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If simulators and mannequins are used to train students on auscultation devices, then abnormal physical findings can be simulated, but the training lacks one-on-one interaction with real patients

Engineering Contradiction:

Improvesimulation of abnormal findingsVSAvoidtraining effectiveness

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the advantages of both standardized patients and simulators by combining wireless audio transmission technology with real stethoscopes. This allows the delivery of simulated abnormal findings (advantage of mannequins) through real auscultation devices used with real patients present (advantage of standardized patients), creating a hybrid training approach.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If acoustic stethoscopes are used for auscultation, then sound transmission from head piece to ears is achieved, but the ability to simulate abnormal auditory findings is limited

Engineering Contradiction:

Improvesound transmission functionVSAvoidsimulation capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces the purely mechanical/acoustic sound transmission system of traditional stethoscopes with an electronic wireless audio transmission system. Instead of relying solely on acoustic waves traveling through tubing, the system uses wireless electromagnetic signal transmission to deliver abnormal sound recordings to the stethoscope's speaker, which then reproduces the sounds acoustically.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An arrangement and method for auscultation training is provided including a transmitter associated with an audio device for transmitting an audio signal to an auscultation device. The auscultation device may include a receiver for receiving the audio signal from the transmitter and a speaker for relaying the sound to the end user. The arrangement may allow for the broadcast of simulated medical sounds to a generally, normal appearing auscultation device for the purposes of teaching or testing using simulated patient scenarios, while allowing for normal person-to-person interaction between the simulated patient and physician.
