Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a balloon catheter is used for coronary sinus occlusion, then flow redistribution is improved, but the device lacks adjustable flow restriction capability

Engineering Contradiction:

Improveflow restriction adjustabilityVSAvoidcatheter structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the occlusion device adjustable rather than fixed. The balloon catheter incorporates pressure sensors and control systems that allow the occlusion level to be dynamically modified during the procedure, enabling the device to adapt to different physiological conditions and treatment requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes physical parameters by introducing pressure sensors that monitor vascular pressure and allow adjustment of the occlusion degree. By modifying pressure parameters and flow restriction levels, the system achieves adaptable flow control while maintaining a relatively simple catheter structure through parameter-based control rather than mechanical complexity.

Inventive Principle:

Principle #35Parameter changes

2Extent of automation

If intermittent occlusion is implemented to improve retrograde perfusion, then myocardial salvage is enhanced, but precise control of occlusion timing and duration is limited

Engineering Contradiction:

Improveocclusion control automationVSAvoidocclusion timing precision

Core Design Contradiction:

Extent of automationVSLoss of time

Solution Approach 1:

The patent implements feedback control by incorporating pressure sensors that continuously monitor vascular pressure during occlusion. The system uses this feedback information to automatically adjust occlusion timing and duration, enabling precise control of the intermittent occlusion protocol and optimizing myocardial salvage while minimizing treatment time.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical control with automated electronic control systems. Pressure sensors and electronic control circuits substitute for manual timing mechanisms, providing automated and precise control of occlusion timing and duration, thereby reducing operator error and optimizing treatment protocols.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If pressure sensors are added to enable variable flow restriction, then flow control precision is improved, but device complexity increases

Engineering Contradiction:

Improvepressure measurement accuracyVSAvoidcatheter system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by designing pressure sensors that serve multiple functions: they measure pressure for feedback control, guide occlusion timing, and monitor treatment efficacy. This multi-functionality justifies the addition of sensors while minimizing overall system complexity, as the same sensing elements perform multiple critical roles in the treatment protocol.

Inventive Principle:

Principle #6Universality (Multi-functionality)
