Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If invasive cardiac assistance systems are used to support circulatory function, then circulatory assistance effectiveness is improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent replaces complex mechanical invasive systems with a pneumatic-hydraulic system using a flexible multilayer structure that utilizes fluid pressure waves to generate pulsatile effects externally on the body, eliminating the need for surgical implantation while maintaining circulatory support functionality
Solution Approach 2:
The patent introduces a flexible multilayer structure as an intermediary between the external environment and the body's circulatory system, allowing non-invasive transmission of pulsatile pressure waves through the skin to achieve circulatory assistance without direct mechanical intervention
2Reliability
If invasive cardiac assistance systems are implemented, then circulatory support is achieved, but the cost of implementation and manufacturing increases
Solution Approach 1:
The patent employs a flexible multilayer structure that can be manufactured at low cost using simple materials and processes, making the device economically viable for widespread use without requiring expensive specialized components or infrastructure
Solution Approach 2:
The invention replaces expensive complex mechanical systems with a simpler pneumatic-hydraulic system using flexible membranes and fluid pressure, significantly reducing manufacturing costs while maintaining therapeutic effectiveness
3Reliability
If general circulatory intervention is performed at the heart level, then overall circulatory function is improved, but the ability to target specific body parts is lost
Solution Approach 1:
The patent applies different pulsatile interventions to different body parts by positioning the flexible multilayer structure locally on the target area, allowing customized treatment for specific regions such as legs, arms, or face while maintaining overall circulatory health
Solution Approach 2:
The invention enables segmentation of circulatory treatment by allowing independent application of pulsatile devices to different body parts, so that each region can receive tailored circulatory support without affecting other areas
4Measurement precision
If specialized medical sites and qualified personnel are required for circulatory assistance, then treatment precision is improved, but ease of operation and accessibility deteriorate
Solution Approach 1:
The patent designs a system that can be easily operated by users themselves or with minimal assistance, using simple application of the flexible multilayer structure and basic control mechanisms, making circulatory assistance accessible outside specialized medical facilities
