Solution Overview

Problem

Existing methods for attaching leak detection sensors to patients' bodies are time-consuming and unreliable, particularly when detecting extravascular leaks during chemical liquid injections in medical imaging procedures.

Innovation Solution

A sensor pad kit with a flexible adhesive surface, extended portions for secure attachment, and a peelable film for easy application, which includes a sensor holding portion and a fixing member to stabilize the sensor device on the patient's body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a band fixing method is used to attach the sensor device to the patient's body, then the sensor can be attached to the patient's arm, but the fixing process becomes time-consuming and the reliability varies according to the operator

Engineering Contradiction:

Improvefixing reliabilityVSAvoidattachment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The sensor pad is divided into a sensor holding portion and multiple extended portions, where the extended portions can be separately positioned and fixed to different locations on the patient's body, enabling more stable attachment without requiring complex bandaging procedures

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

An adhesive is introduced as an intermediary substance between the sensor pad and the patient's skin, allowing for quick and reliable attachment without requiring time-consuming bandaging or complex fixing procedures by operators

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a band fixing method is used to attach the sensor device, then the sensor can be secured to the patient's body, but the operator skill level affects the reliability of attachment

Engineering Contradiction:

Improveattachment easeVSAvoidfixing reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The sensor pad design allows the extended portions to naturally extend toward the outer side of the sensor holding portion, enabling the pad to self-position and self-adhere to the patient's body contours without requiring skilled manual manipulation or complex bandaging techniques

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The adhesive acts as a mediator that eliminates the need for operator skill in securing the sensor, as the adhesive property automatically ensures reliable attachment when the pad is applied to the patient's skin

Inventive Principle:

Principle #24Intermediary (Mediator)
