Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional shunts with fixed geometry are used, then the device complexity is reduced and ease of manufacture is improved, but the adaptability to individual patient needs deteriorates
Solution Approach 1:
The shunt lumen geometry is made dynamically adjustable through an actuation mechanism that can change the lumen size from a first configuration to a second configuration. This allows the shunt to adapt to individual patient needs and be titrated over time, transforming a static device into a dynamic one that can respond to changing therapeutic requirements.
Solution Approach 2:
The invention changes the geometric parameters of the shunt lumen by adjusting its size and shape through the actuation mechanism. This allows modification of flow characteristics and therapeutic effect by changing physical dimensions of the lumen, enabling personalized therapy without requiring multiple different fixed-geometry devices.
2Adaptability or versatility
If adjustable shunting systems are implemented, then the adaptability and personalized therapy are improved, but the energy consumption increases
Solution Approach 1:
The actuation mechanism is designed to require energy only during discrete adjustment events rather than continuous operation. The shunt can maintain its adjusted geometry without ongoing energy input, consuming power only when transitioning between configurations, thereby reducing overall energy consumption while preserving adaptability.
Solution Approach 2:
The system incorporates sensors that automatically detect patient-specific conditions and trigger adjustments without requiring continuous external control. The device monitors its own performance and self-regulates the lumen geometry based on detected physiological parameters, reducing the need for external energy input and control infrastructure.
3Reliability
If the shunt lumen geometry is optimized for maximum therapy, then the therapeutic effect is improved, but the risk of creating new patient issues increases
Solution Approach 1:
The ability to dynamically adjust lumen geometry allows the system to optimize therapy while avoiding complications by making incremental adjustments. If maximum therapy creates harmful effects, the lumen can be reduced to a intermediate or minimum configuration, providing a safety mechanism that prevents permanent damage while maintaining therapeutic benefit.
Solution Approach 2:
The system incorporates sensors that provide feedback on patient response to shunting therapy. This feedback loop allows real-time monitoring of therapeutic effects and potential complications, enabling adjustments to be made before harmful effects become severe. The feedback mechanism ensures the system operates within safe parameters while maximizing benefit.
