Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveblood vessel compression effectivenessVSAvoiddevice construction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvehemostatic controlVSAvoidprocedure time
Core Design Contradiction:
ReliabilityVSLoss of time

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #10Preliminary action

3Reliability

If pressure is applied to the insertion site, then hemostasis is achieved, but venous blood outflow may be obstructed

Engineering Contradiction:
ImprovehemostasisVSAvoidvenous blood outflow obstruction
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

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

Inventive Principle:
Principle #3Local quality
