Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If standardized phlebological devices are introduced, then application precision and treatment effectiveness are improved, but device complexity increases

Engineering Contradiction:
Improveapplication precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The device is divided into distinct functional segments: an inflatable tubular element for pressure application, an adhesive layer for secure attachment, and compression means for pressure control. This segmentation allows each component to be optimized independently while maintaining overall standardization and precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inflatable tubular element serves multiple functions: it provides eccentric pressure, maintains positional stability through adhesion, and allows adjustable compression levels. This multi-functionality reduces the need for multiple specialized devices while maintaining application precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If adjustable compression means are added, then adaptability to various anatomical conditions is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The compression means allow dynamic adjustment of pressure levels during treatment. The system transitions from a static compression device to a dynamic one where pressure can be modified based on patient response and anatomical variations, enhancing adaptability without requiring multiple fixed-pressure devices.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device enables change of the compression parameter (pressure level) through adjustable compression means. This allows the same standardized device to adapt to different anatomical conditions by simply adjusting the pressure parameter rather than requiring different devices for each condition.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If simple application procedures are implemented, then ease of operation is improved, but reliability of stable pressure application may worsen

Engineering Contradiction:
Improveease of operationVSAvoidstability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The adhesive layer is pre-applied to the tubular element during manufacturing, eliminating the need for separate adhesive application steps during patient treatment. This preliminary action simplifies the procedure while ensuring reliable and stable attachment of the device to the patient's anatomy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The adhesive layer acts as an intermediary between the tubular element and the patient's skin, providing a simple yet reliable connection mechanism. This intermediary component enables easy application and removal while maintaining stable pressure application throughout treatment.

Inventive Principle:
Principle #24Intermediary (Mediator)
