Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electromagnetic fields are applied to loosen electrostatic bonds between toxins and proteins, then toxin removal efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies electromagnetic fields with specific frequency ranges (e.g., 1 MHz to 1 GHz) to alter the physical state of electrostatic bonds between toxins and proteins. By changing the electromagnetic parameters, the system enhances toxin dissociation and removal efficiency without requiring fundamental changes to the dialysis mechanism.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary mechanism to indirectly affect toxin-protein interactions. Rather than directly manipulating the chemical bonds, the electromagnetic field serves as a mediator that loosens electrostatic bonds, facilitating subsequent toxin removal through the dialysis membrane.
2Reliability
If capacitive coupling is used to generate electromagnetic fields in the dialysis area, then sterility is maintained, but electromagnetic field strength is reduced
Solution Approach 1:
The capacitive coupling structure acts as an intermediary that transmits electromagnetic energy without direct contact between the generator and blood flow. The capacitor plates serve as a mediator that allows field generation while maintaining the sterile barrier, accepting reduced field strength as a trade-off for sterility preservation.
Solution Approach 2:
The patent replaces direct mechanical or electrical contact systems with a capacitive field-based system. Instead of inserting electrodes into the blood flow, the system uses capacitive coupling to generate electromagnetic fields through the dialysis membrane, substituting a non-contact mechanism that inherently maintains sterility.
3Reliability
If dialysis is performed frequently to improve patient health, then health outcomes are improved, but patient burden and societal costs increase
Solution Approach 1:
By changing the operational parameters of dialysis through electromagnetic field application, the system achieves more effective toxin removal in each session. This enhanced efficiency per session reduces the frequency requirement, thereby decreasing patient burden and time loss while maintaining or improving health outcomes.
Solution Approach 2:
The electromagnetic field-assisted dialysis system provides enhanced toxin removal capability that enables the treatment to be more self-sufficient in achieving therapeutic goals. Each dialysis session becomes more effective at removing both free and protein-bound toxins, reducing dependence on frequent treatments.
