Solution Overview

Problem

Current breast implants often result in complications such as visible and palpable edges, uneven distribution of volume, and gravitational displacement, leading to high rates of revision surgeries and patient dissatisfaction.

Innovation Solution

A pyramid-shaped breast implant with a converging footprint and relocated center of gravity, designed to mimic the natural breast shape, featuring V-shaped edges and a paraboloid footprint to improve aesthetic outcomes and resist gravitational pull, along with a method of manufacturing using a 3D mandrel and non-polymerized silicone gel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If round-shaped or teardrop-shaped implants are used, then breast volume is increased, but visible and palpable edges occur

Engineering Contradiction:

Improvebreast volumeVSAvoidvisible and palpable edges

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The implant uses a pyramidal shape with asymmetric geometry rather than traditional round or teardrop forms. This asymmetric design with converging sides creates a more natural breast contour that eliminates visible and palpable edges while maintaining adequate breast volume enhancement.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The implant changes the geometric parameters from spherical/teardrop to pyramidal form with specific angle configurations (e.g., 60-degree angles). This parameter change in shape geometry fundamentally alters how the implant integrates with breast tissue, eliminating edge visibility while preserving volume.

Inventive Principle:

Principle #35Parameter changes

2Quantity of substance

If traditional implant shapes are used, then breast augmentation is achieved, but unnatural appearance results

Engineering Contradiction:

Improvebreast volumeVSAvoidnatural breast shape

Core Design Contradiction:

Quantity of substanceVSShape

Solution Approach 1:

The pyramidal implant design with its asymmetric geometry and converging sides naturally mimics the anatomical structure of the breast, creating a more authentic appearance compared to symmetric round or teardrop shapes that often produce artificial contours.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

While using straight edges characteristic of pyramidal geometry, the implant incorporates curved surfaces on its lateral faces that smoothly transition to match the natural curvature of breast tissue, achieving both geometric precision and organic appearance.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Reliability

If implants are placed under breast tissue, then breast reconstruction is achieved, but gravitational displacement occurs

Engineering Contradiction:

Improvebreast reconstructionVSAvoidimplant position

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The pyramidal shape with its converging sides and specific center of gravity positioning creates a self-stabilizing structure that resists gravitational displacement. The geometry inherently counters the downward force, maintaining implant position stability without requiring additional fixation mechanisms.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The implant design creates a state of gravitational equilibrium where the center of gravity is positioned such that the implant experiences minimal displacement forces. This equipotential positioning ensures stable integration with breast tissue under gravitational influence.

Inventive Principle:

Principle #12Equipotentiality

4Quantity of substance

If volume is concentrated at lower part, then teardrop shape is achieved, but deficient upper pole results

Engineering Contradiction:

Improvevolume distributionVSAvoidupper pole fullness

Core Design Contradiction:

Quantity of substanceVSShape

Solution Approach 1:

The pyramidal implant divides the breast volume into distinct segments along its height, with each triangular face contributing to both upper and lower pole fullness. This segmentation ensures balanced volume distribution that prevents upper pole deficiency while maintaining natural lower pole fullness.

Inventive Principle:

Principle #1Segmentation
