Modular Transdermal Assembly for Varying Bone Stump Anatomies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transdermal intraosseous devices are not well-suited for accommodating varying anatomies with different distances between a bone stump and the distal skin area, limiting their adaptability and effectiveness in coupling external prosthetic devices.
Innovation Solution
A modular transdermal assembly kit that includes a variety of modular transdermal portions and bone fixators of different lengths and geometries, allowing for customizable coupling to accommodate unique anatomies, along with modular skin integration components to enhance fixation and compatibility with external prosthetic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current transdermal intraosseous devices are used, then the device structure is simple, but the device cannot accommodate varying anatomies with different distances between bone stump and distal skin area
Solution Approach 1:
The transdermal assembly is divided into multiple modular components including a bone fixator portion, a transdermal portion, and a prosthetic interface portion. Each component can be independently selected and configured based on the patient's specific anatomy, allowing the system to adapt to varying distances between the bone stump and distal skin area while maintaining a relatively simple individual component design.
Solution Approach 2:
The modular components are designed with universal coupling mechanisms that allow the same basic components to be configured for different anatomical variations. The bone fixator, transdermal portion, and prosthetic interface can be combined in various configurations to accommodate different patient anatomies, making the system multi-functional without requiring completely different devices for each case.
2Adaptability or versatility
If modular components of different lengths are provided, then adaptability to varying separation distances is improved, but the quantity of components increases
Solution Approach 1:
The modular transdermal assembly allows for dynamic configuration based on the patient's specific anatomical needs. By providing components in a kit with different lengths and selecting the appropriate combination, the system can adapt to varying separation distances without requiring an excessive number of components. The dynamic assembly process allows optimization of the component set for each specific case.
3Adaptability or versatility
If modular transdermal assembly is used, then adaptability to varying anatomies is improved, but the device complexity increases
Solution Approach 1:
The assembly is segmented into distinct functional modules (bone fixator, transdermal portion, prosthetic interface) that can be independently configured. This segmentation allows for customizable coupling to accommodate unique anatomies while keeping each individual component relatively simple in design, thereby managing overall system complexity through modular organization.

AI summary
A modular transdermal assembly configured to couple an external prosthetic device to a bone stump. The assembly includes a modular transdermal portion and a bone fixator. The modular transdermal portion includes an interface portion configured to couple with the external prosthetic device. The bone fixator is configured to be secured to the bone stump and couple with the modular transdermal portion to retain the modular transdermal portion relative to the bone stump.
