Solution Overview

Problem

Current methods for repairing tympanic membrane perforations are inefficient and require multiple devices and procedures, leading to increased physician time and patient discomfort, while also not effectively promoting epithelial tissue growth for natural sealing.

Innovation Solution

A device and method that includes a patch guiding mechanism for inserting a biocompatible patch under the tympanic membrane, a debridement mechanism for removing peripheral tissue, and an adhesive application mechanism, allowing for rapid attachment and release of the patch, which is designed for single-use and includes features to promote epithelial growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple devices and procedures are used for repairing tympanic membrane perforations, then the repair can be performed, but physician time increases and patient discomfort increases

Engineering Contradiction:
Improverepair effectivenessVSAvoidphysician time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent combines multiple previously separate devices and procedures into a single integrated repair system. The applicator integrates patch delivery, adhesive application, and positioning functions that previously required multiple separate instruments and steps, thereby reducing physician time while maintaining repair effectiveness

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The repair device is designed as a multi-functional applicator that can perform multiple operations (patch insertion, adhesive application, positioning) through a single device. This universal device eliminates the need for multiple specialized instruments, reducing procedural complexity and time requirements

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

2Reliability

If multiple devices and procedures are used for repairing tympanic membrane perforations, then the repair can be performed, but patient discomfort increases

Engineering Contradiction:
Improverepair effectivenessVSAvoidpatient discomfort
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By combining multiple procedural steps into a single integrated device operation, the number of insertions, manipulations, and procedural interventions is reduced. This minimizes trauma to the ear canal and tympanic membrane area, thereby reducing patient discomfort while achieving the same repair outcome

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If conventional methods are used, then repair is performed, but epithelial tissue growth is not effectively promoted

Engineering Contradiction:
Improverepair completionVSAvoidepithelial tissue growth rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent modifies the chemical and physical parameters of the repair interface by introducing specific adhesive compositions and surface treatments that create an optimal environment for epithelial cell proliferation. These parameter changes accelerate natural tissue growth rates while ensuring reliable repair completion

Inventive Principle:
Principle #35Parameter changes

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 solution enables quick and efficient repair of tympanic membrane perforations, reducing physician time and patient discomfort, while promoting faster epithelial tissue growth and natural sealing of the perforation, with the ability to be used without painkillers or additional medication.

Implementation Method 1

The patch is removably attached via suction to the distal end of the tubular applicator member so that the adhesive layer faces away from the elongate applicator member
