Modular Distal Finger Prosthesis With Detachable Functional Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current finger prosthetics lack adaptability and customization options to fit individual user needs, both functionally and aesthetically, and do not easily accommodate additional functional units.
Innovation Solution
A modular finger prosthesis system featuring a distal finger prosthesis module with a connecting element for easy attachment to a proximal module and a receiving unit for detachable functional units, allowing for quick adaptation and customization through 3D printing, with interchangeable modules and functional units such as LED lighting, tools, or artificial fingernails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional non-modular finger prosthesis is used, then the structure is simple and easy to manufacture, but the adaptability and customization options are limited
Solution Approach 1:
The finger prosthesis is divided into multiple detachable modules including a proximal module, intermediate module, and distal module. Each module can be independently manufactured and then assembled together through connecting elements, enabling both simple manufacturing of individual components and high adaptability through various combination possibilities.
2Adaptability or versatility
If a fixed-function prosthesis is used, then the device complexity is low, but the ability to accommodate additional functional units is poor
Solution Approach 1:
The distal module incorporates a receiving unit designed to accept various functional units such as artificial fingernails, tools, or other attachments. This universal interface allows a single base module to serve multiple functions depending on which functional unit is attached, achieving high customization without requiring multiple specialized devices.
3Ease of operation
If a modular design with detachable connections is implemented, then the ease of operation for assembly and disassembly is improved, but the reliability of the connection may be compromised
Solution Approach 1:
The connecting elements incorporate self-aligning and self-locking features that automatically ensure proper engagement when modules are assembled. The design includes complementary geometric shapes (protrusions and recesses) that guide correct positioning and provide automatic mechanical locking, achieving both ease of operation and high connection reliability without requiring complex assembly procedures.
