Solution Overview

Problem

Existing nostril spreading implants are unsuitable for unilateral application, require complex surgical procedures, and often lead to cavities or poor healing due to mismatched geometry with the nasal structure, necessitating significant material and manufacturing effort.

Innovation Solution

A rhinological implant with a triangular base body, bent to fit the inner nostril curvature, is designed for unilateral application, reducing material use and manufacturing complexity, ensuring a secure fit without cavities, and promoting tissue integration through perforations and rounded edges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional bilateral implants spanning the nasal septum are used, then structural support is provided, but material consumption and manufacturing complexity increase significantly

Engineering Contradiction:
Improvestructural supportVSAvoidmaterial consumption
Core Design Contradiction:
StrengthVSQuantity of substance

Solution Approach 1:

The implant is divided into functional zones: a triangular base body for structural support, side sections for attachment, and rounded edges for tissue compatibility. This segmentation allows each part to perform its specific function efficiently, reducing overall material consumption while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts only the essential functional elements needed for unilateral nostril support, eliminating the need for extensive bilateral structures. The implant takes out only the minimum material required to achieve the spreading function, significantly reducing material consumption compared to traditional designs.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If complex surgical procedures are used for implantation, then secure attachment is achieved, but surgical stress and procedure time increase

Engineering Contradiction:
Improvesecure attachmentVSAvoidsurgical procedure time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The implant is pre-shaped with a triangular base body and attached side sections before implantation. The rounded edges are pre-formed to match the natural curvature of the nasal structure. This preliminary preparation allows for quicker implantation without compromising secure attachment, reducing surgical procedure time while maintaining reliability.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If implants with sharp edges are used, then manufacturing precision is easier to achieve, but tissue compatibility and healing quality deteriorate

Engineering Contradiction:
Improvegeometric precisionVSAvoidtissue irritation
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The implant features rounded edges and a curved triangular base body that follow the natural curvature of the nasal structure. This curvature design maintains manufacturing precision while eliminating sharp edges that could irritate tissue, thereby improving tissue compatibility and healing quality without sacrificing geometric accuracy.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Quantity of substance

If unilateral implant design is used, then material consumption is reduced, but adaptation to bilateral nasal structure becomes more difficult

Engineering Contradiction:
Improvematerial consumptionVSAvoidadaptation to nasal structure
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The triangular base body with attached side sections is designed as a universal implant that can be applied unilaterally to either nostril. The symmetric triangular design allows the same implant to adapt to both left and right nasal structures, providing versatility while maintaining reduced material consumption compared to bilateral implants.

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

AI summary

An implant (40) for spreading a nostril, which, in the implanted state, lies fully against an inner surface of a nostril and is constructed from a blank made of thin sheet metal and provided with a plurality of continuous perforations, wherein the initially flat blank is bent into a spatial shape curved out of the sheet plane, which follows the natural curvature of the inner side of the soft nasal lateral wall; wherein the implant, in the implanted state, lies fully against only one inner surface of a single one of the two nostrils and has a triangular base body (41), in which, starting from a triangular vertex (S), two cathetial edges (42', 43') are arranged at a triangular angle to one another, each leading away from the triangular vertex and extending on both sides in the direction of a hypotenuse edge (44') opposite the triangular vertex, is characterized in thatThe base tips of the triangular body, where each cathetial edge meets the hypotenuse edge opposite the triangle apex, are shortened or truncated, so that the end of the respective cathetial edge facing away from the triangle apex is connected to one end of the hypotenuse edge via another edge line (42x'). This device enables a permanently secure fit of the implant because its shape allows it to be fitted particularly well and optimally across the entire surface of the inner side of the nose.
