Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing treatments are used for abnormal fluid transport in the brain, then treatment is provided, but fluid flow enhancement is inadequate
Solution Approach 1:
The patent replaces conventional mechanical or chemical treatment methods with electromagnetic field application. Specifically, magnetohydrodynamic forces generated by applying magnetic fields to conductive cerebrospinal fluid create body forces that enhance fluid transport without mechanical intervention, directly resolving the contradiction between treatment provision and treatment effectiveness
Solution Approach 2:
The patent changes the physical state and transport parameters of cerebrospinal fluid by applying electromagnetic fields. The magnetic field strength, frequency, and duration are adjusted as controllable parameters to optimize fluid flow enhancement, transforming the fluid dynamics parameters to achieve both adequate treatment and improved fluid transport efficiency
2Productivity
If electromagnetic fields are applied to enhance fluid transport, then fluid flow is improved, but device complexity increases
Solution Approach 1:
The patent employs electromagnetic field apparatus that can serve multiple functions: generating magnetic fields for magnetohydrodynamic fluid transport, providing image guidance for precise targeting, and potentially monitoring treatment response. This multi-functionality reduces the need for separate devices, thereby managing device complexity while achieving fluid transport enhancement
Solution Approach 2:
The patent uses the conductive properties of cerebrospinal fluid as an intermediary medium. The electromagnetic fields interact with the conductive fluid to generate MHD forces, using the fluid's inherent electrical conductivity as a mediator to translate electromagnetic energy into mechanical fluid motion, simplifying the direct coupling between the electromagnetic system and fluid transport
