Solution Overview

Problem

Existing devices for reshaping malformed auricles in newborns or infants face issues such as incorrect application, use of clips and adhesive tapes causing discomfort, difficulty in removal, and potential for adhesive residue, making them difficult to use and potentially harmful.

Innovation Solution

A device comprising two molded parts with integrated closure elements, such as magnetic or mechanical fasteners, that securely fit over the ear without the need for additional clips or adhesive tapes, ensuring easy application and removal, and is manufactured to fit the individual ear shape to prevent pressure points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If clips and adhesive tapes are used to secure the device to the ear, then the device can be firmly fixed, but the infant experiences discomfort and difficulty in removal

Engineering Contradiction:
Improvefixing strengthVSAvoidease of application and removal
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent removes clips and adhesive tapes from the device design, replacing them with an integrated closure system consisting of interlocking molded parts. This extraction of harmful elements eliminates the need for separate fastening components that cause discomfort and application difficulty.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The closure system is integrated directly into the molded parts of the device. The first and second molded parts include interlocking features (such as snaps, clips, or friction-fit mechanisms) that are built into the structure itself, combining the functions of the device body and fastening system into a unified design.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If adhesive tapes are used to secure the device, then firm fixation is achieved, but adhesive residue is left on the infant's head

Engineering Contradiction:
Improvefixing strengthVSAvoidadhesive residue
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent completely removes adhesive tapes from the device design, replacing them with mechanical interlocking mechanisms integrated into the molded parts. This eliminates the source of adhesive residue and associated harmful effects on the infant's skin.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If a generic device design is used, then manufacturing is simpler, but incorrect application occurs

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidapplication accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The device is pre-formed as a complete three-dimensional mold that includes the closure system integrated into the molded parts. This preliminary formation of the complete structure ensures that the device is ready for immediate use with correct geometry and fit, eliminating the need for complex assembly steps and ensuring proper application.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If the device is designed for easy removal, then comfort is improved, but securing strength is reduced

Engineering Contradiction:
Improveease of removalVSAvoidsecuring strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The closure system provides dynamic functionality with reversible fastening mechanisms that allow easy attachment and detachment. The interlocking molded parts can be securely engaged to provide firm fixation during wear, yet can be easily separated when removal is needed, adapting to the operational requirements of both securement and removal.

Inventive Principle:
Principle #15Dynamics
