Prefabricated Nose Model with Adjustable Cartilage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nose models used in rhinoplasty procedures lack the ability to demonstrate the movement of lower lateral cartilages, making it difficult for patients to understand the changes in nose appearance during the surgery, as they only show cross-sectional shapes and do not allow for realistic cartilage movement.
Innovation Solution
A prefabricated nose model with a main body, a detachable fixing body, and adjustable lower lateral cartilage portion, allowing for the simulation of rhinoplasty changes by moving the lower lateral cartilage, enabling better patient understanding through three-dimensional explanation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional nose model shows only cross-sectional shape, then the model structure is simple, but the lower lateral cartilage movement cannot be demonstrated
Solution Approach 1:
The nose model is divided into multiple detachable components: a main body, a separate lower lateral cartilage, and a fixing body with holding space. This segmentation allows the lower lateral cartilage to be independently manipulated and moved to demonstrate surgical procedures, while keeping the overall model structure relatively simple through modular design.
2Ease of repair
If the nose model is made as a single integrated piece, then the model is easy to manufacture, but damaged parts cannot be easily replaced
Solution Approach 1:
The model consists of separable components (main body, lower lateral cartilage, fixing body) that can be easily detached and reattached. This allows damaged parts to be replaced without manufacturing the entire model anew, while the manufacturing process remains straightforward through modular assembly of pre-fabricated components.
3Loss of information
If the nose model uses fixed cartilage structure, then the model structure is stable, but patient understanding of rhinoplasty changes is limited
Solution Approach 1:
The lower lateral cartilage is designed to be movable within the holding space of the fixing body, allowing it to be repositioned dynamically to demonstrate different surgical outcomes. This dynamic capability enhances patient understanding of rhinoplasty changes while the cartilage maintains structural stability when positioned.

AI summary
Proposed is a prefabricated nose model for explaining a rhinoplasty procedure. The prefabricated nose model is used to show a change in the appearance of the nose according to the rhinoplasty procedure. The prefabricated nose model includes a main body having a front surface provided with a nasal bone corresponding portion and having a penetration space provided on a lower side of the nasal bone corresponding portion, a fixing body detachably coupled to the penetration space, an upper lateral cartilage corresponding portion which protrudes forward from the main body while being supported on the fixing body and which is positioned at a lower portion of the nasal bone corresponding portion; and a lower lateral cartilage corresponding portion mounted on a lower side of the upper lateral cartilage corresponding portion such that a position of the lower lateral cartilage corresponding portion is capable of being adjusted.
