Infant Ear Molding Splint With Integrated Closure Fit
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
3Ease of manufacture
If a generic device design is used, then manufacturing is simpler, but incorrect application occurs
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.
4Ease of operation
If the device is designed for easy removal, then comfort is improved, but securing strength is reduced
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.
