Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pharmacological treatments (anticoagulants) are used to prevent blood coagulation, then thrombi formation is reduced, but the risk of bleeding and excessive hemorrhage increases
Solution Approach 1:
The patent extracts and removes existing thrombi from blood vessels using a mechanical scraping device, rather than relying on pharmacological prevention. The thrombus removal device with scraper blades physically extracts thrombi adhered to vessel walls, eliminating the need for prolonged anticoagulant use and its associated bleeding risks.
Solution Approach 2:
The device enables self-service thrombus removal through automated propulsion and scraping mechanisms. The propulsion device automatically advances the scraper along the blood vessel wall, and the drive module automatically actuates the scraper blades, reducing the need for manual intervention and allowing the system to perform thrombus removal autonomously.
2Reliability
If surgical interventions are used to manually remove thrombi, then vessel patency is ensured, but significant risks, pain, and extended recovery periods occur
Solution Approach 1:
The patent replaces the traditional mechanical surgical intervention with an automated robotic system. Instead of manual surgical tools, the invention uses an automated propulsion device with controlled scraper blades that can be precisely positioned and actuated to remove thrombi, reducing surgical trauma and recovery time.
Solution Approach 2:
The device segments the thrombus removal function into distinct modular components: a propulsion device for navigation, a drive module for actuation, and scraper blades for thrombus removal. This segmentation allows each component to be optimized independently and facilitates easier deployment with reduced surgical complexity.
3Productivity
If traditional thrombi removal methods are used, then treatment is provided, but precision and safety concerning vessel structural integrity are insufficient
Solution Approach 1:
The patent incorporates a camera lens that provides real-time visual feedback during thrombus removal. The camera captures images of the blood vessel interior and thrombus location, allowing the operator to precisely control the scraper's position and movement, ensuring accurate thrombus removal while preserving vessel structural integrity.
Solution Approach 2:
The device employs dynamic control of the scraper blades through the drive module, which can adjust the scraping action based on real-time conditions. The propulsion device can also dynamically adjust its speed and position, allowing adaptive thrombus removal that responds to the specific characteristics of each thrombus and vessel segment.

AI summary
A thrombus removal device, comprises a shell, a window, a propulsion device, a propulsion motor, a camera lens, a left thrombus scraper, a right thrombus scraper, a drive module, a drive motor, a control module, and a power supply module. The left and right thrombus scrapers are designed to remove thrombi adhered to the inner walls of blood vessels. With the integration of the camera lens, medical professionals can monitor the internal conditions of the blood vessels in real-time during the treatment process. This enhances the precision of thrombus removal and ensures the safety of the vascular structure, thereby reducing the risk of accidental injuries. Furthermore, the propulsion device enables the thrombus removal device to autonomously navigate within the blood vessels. This not only alleviates the manual operation workload of medical personnel but also optimizes the operational process and reduces procedure time, effectively enhancing overall operational efficiency and convenience.
