Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hemostatic devices are used, then blood vessel compression can be achieved, but the device construction becomes complex and requires additional personnel or equipment
Solution Approach 1:
The device divides the compression function into three distinct compression areas: first compression area for direct blood vessel compression, second compression area for distributing pressure to the limb, and third compression area for manual pressure control. This segmentation allows each area to perform its specific function efficiently, achieving reliable hemostasis while keeping the overall device structure simple and self-contained
Solution Approach 2:
The device enables a single operator to perform hemostatic compression without requiring additional personnel or complex equipment. The manual compression control area allows the operator to directly adjust pressure, and the self-contained structure with integrated holding elements eliminates dependency on external devices or assistants
2Reliability
If multiple consecutive actions are performed for hemostasis, then proper hemostatic control is achieved, but the procedure time increases and requires coordination between multiple personnel
Solution Approach 1:
The device combines multiple hemostatic actions into a single integrated structure. The compression areas, holding elements, and fastening means work together simultaneously to achieve hemostatic control in one application step, eliminating the need for sequential actions of band placement, fastening, and pressure adjustment that require coordination between multiple personnel
Solution Approach 2:
The device is pre-configured with compression areas and holding elements positioned to automatically distribute pressure correctly upon application. The structure is designed beforehand to maintain proper pressure levels without requiring step-by-step adjustment, reducing procedure time and eliminating the need for coordinated multi-personnel actions
3Reliability
If pressure is applied to the insertion site, then hemostasis is achieved, but venous blood outflow may be obstructed
Solution Approach 1:
The device applies compression locally and selectively through the first compression area targeted at the blood vessel insertion site, while the second compression area distributes pressure to the surrounding limb tissue. This localized compression approach achieves hemostasis at the specific insertion point without applying uniform pressure that would obstruct venous outflow from the entire limb
