Customized Breast Prosthesis Density Matching via 3D Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional breast prostheses for mastectomy patients often cause weight imbalance, a foreign body sensation, and postural distortion due to differences in density and shape from natural breasts, leading to reduced self-esteem and poor posture.
Innovation Solution
A method and system for manufacturing customized breast prostheses using 3D scanning and 3D printing, which involves acquiring shape, volume, and weight data of the resected breast, selecting materials, and designing the prosthesis to match the natural breast's shape, volume, and density, ensuring weight balance through adjustments in glandular and fat tissue layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional breast prostheses are used, then the basic function of breast reconstruction is achieved, but weight imbalance and foreign body sensation occur due to different density from natural breast
Solution Approach 1:
The patent applies parameter changes by precisely controlling the density parameter of the prosthesis material to match the density of natural breast tissue. The prosthesis is designed with a density of 0.9-1.1 g/cm³ to closely replicate natural breast density, thereby reducing foreign body sensation and improving weight balance.
Solution Approach 2:
The patent uses composite materials by combining multiple materials with different density characteristics to create a prosthesis that matches natural breast density. The prosthesis may incorporate layers or regions with different material compositions to achieve the desired density distribution, reducing the foreign body sensation while maintaining structural integrity.
2Manufacturing precision
If conventional breast prostheses are used, then the basic function of breast reconstruction is achieved, but postural distortion occurs due to horizontal imbalance
Solution Approach 1:
The patent applies parameter changes by precisely controlling the shape and volume parameters of the prosthesis to match the patient's natural breast characteristics. The prosthesis is customized in terms of shape, volume, and weight distribution to eliminate horizontal imbalance, thereby preventing postural distortion and back pain.
Solution Approach 2:
The patent applies local quality by creating region-specific variations in the prosthesis structure to match the natural breast's internal architecture. Different regions of the prosthesis are designed with varying tissue densities and structural characteristics to replicate the natural breast's heterogeneity, ensuring proper weight distribution and preventing postural distortion.
3Manufacturing precision
If 3D scanning and 3D printing are used to create customized prosthesis, then shape, volume, and weight accuracy are improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies copying by using 3D scanning technology to create a digital replica of the patient's natural breast geometry. This digital model is then used as the basis for designing the customized prosthesis, allowing for precise replication of shape, volume, and surface characteristics while simplifying the manufacturing process through digital fabrication.
Solution Approach 2:
The patent applies mechanics substitution by replacing traditional mechanical measurement and modeling methods with 3D scanning and digital design technologies. This substitution enables more precise customization of the prosthesis while streamlining the manufacturing process, though it does introduce new technological complexities that must be managed.
