Solution Overview
Problem
Conventional medical aids for intestine examinations are difficult to identify and measure accurately due to their simple and uniform shapes, making it challenging to determine the pass time of the intestine during motility examinations, which hinders accurate diagnosis and prescription.
Innovation Solution
A medical aid featuring recording/measuring members formed from a polymeric composite containing non-harmful radioactive opaque materials, such as barium sulfate, with different shapes and sizes, housed in a biodegradable capsule, allowing for accurate identification and measurement of intestine motility over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional medical aids use simple and uniform shapes, then they are easy to manufacture and take, but they cannot be individually identified for accurate measurement of intestine pass time
Solution Approach 1:
The patent applies local quality by giving each recording member a specific shape characteristic (ring-shaped, ball-shaped, or polyhedral) that corresponds to a specific intake date. This allows each member to have a differentiated local property (shape) that enables identification of when it was taken, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The patent uses shape variations as visual indicators (analogous to color changes) to differentiate between recording members taken on different dates. The distinct shapes (ring, ball, polyhedral) serve as identifiable markers that can be easily distinguished on X-ray images, enabling accurate tracking of pass time without complex identification systems.
2Ease of manufacture
If medical aids are made uniform in shape and size, then manufacturing is simplified, but individual identification becomes impossible when photographed
Solution Approach 1:
The patent maintains ease of manufacture by using simple geometric shapes that can be easily formed through molding processes. Each shape type (ring, ball, polyhedral) represents a basic mold configuration, keeping manufacturing simple while still providing sufficient differentiation to preserve intake date information through shape identification.
Solution Approach 2:
The patent changes the shape parameter of the recording members to encode intake date information. By varying the shape (ring-shaped for first date, ball-shaped for second date, polyhedral for third date), the patent preserves information about when each member was taken without complicating the manufacturing process, as each shape can be produced through standard molding techniques.
3Duration of action of moving object
If multiple medical aids are taken on different dates, then intestine motility can be tracked over time, but accurate identification of pass time becomes difficult with uniform shapes
Solution Approach 1:
The patent enables tracking over multiple dates (first, second, and third intake dates) by assigning distinct local shape characteristics to recording members taken on each date. This allows the examination to span multiple time periods while maintaining precise identification of when each member passed through the intestine, as the unique shapes can be clearly distinguished on sequential X-ray images.
Solution Approach 2:
The patent uses shape variations as visual markers (similar to color coding) to indicate different intake dates. The ring-shaped, ball-shaped, and polyhedral forms serve as easily distinguishable indicators that allow accurate determination of pass time for each individually taken medical aid, enabling precise temporal tracking throughout the examination period.
