Artificial Intestine Bulge Attachment for Secure Implant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for treating intestinal disorders, such as constipation or incontinence, often require invasive surgeries and result in inconvenient and irritating colostomy bags, with existing artificial sphincter systems facing challenges in controlling intestinal content flow and attachment to the body.
Innovation Solution
An artificial intestine section with a wirelessly charged accumulator and bulge structure for frontal attachment, featuring a conduit with a bulge and blocking ring for secure attachment, and a flow control device to manage intestinal contents, reducing the impact of peristaltic waves and improving connection strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an artificial intestine section is implanted to treat intestinal disorders, then the patient's intestinal function is improved, but the attachment security to the intestine is insufficient
Solution Approach 1:
The patent employs a bulge structure extending from the conduit in a circumferential direction, creating a curved geometric feature that prevents the blocking ring from slipping. This curvature-based mechanical interlocking resolves the attachment security issue without requiring complex fastening mechanisms.
Solution Approach 2:
The blocking ring is designed with an inner cross-sectional diameter smaller than the outer diameter of the bulge, creating a dimensional mismatch that prevents axial slippage. This dimensional design adds a radial dimension constraint to the attachment mechanism, improving security without increasing structural complexity.
2Ease of operation
If a colostomy bag with adhesive plate is used to control intestinal contents, then fecal flow control is achieved, but skin irritation occurs
Solution Approach 1:
The patent extracts the adhesive plate and external bag components from the system, replacing them with an internally implanted artificial intestine section. This eliminates the source of skin irritation while maintaining fecal flow control through the implanted device's inherent structure.
3Stability of the object's composition
If peristaltic waves act on the artificial intestine section, then natural intestinal movement is maintained, but connection strength is reduced
Solution Approach 1:
The bulge structure with its curved geometry distributes the forces from peristaltic waves around the circumference, preventing stress concentration at any single point. This curvature design maintains natural intestinal movement while the distributed stress pattern preserves connection strength.
Solution Approach 2:
The blocking ring is pre-positioned to engage with the bulge structure before peristaltic forces act on the system. This preliminary mechanical interlocking prepares the attachment to withstand subsequent peristaltic movements without compromising connection strength.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a more secure and effective means of controlling intestinal content flow, reducing skin irritation and inconvenience, while enhancing the durability of the attachment to the intestine, thereby improving the management of intestinal disorders.
