Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional electronic devices are used to control ion delivery, then electron movement control is achieved, but precision and accuracy for delivering multiple ionic species simultaneously is insufficient
Solution Approach 1:
The device divides the ion delivery system into multiple independent ion pumps, each capable of delivering specific ionic species (H+, Na+, Cl-) independently. This segmentation allows precise control of each ion type while maintaining the ability to deliver multiple ions simultaneously, resolving the contradiction between precision and versatility.
Solution Approach 2:
The ion pump system is designed with multi-functionality to deliver various ionic species through a unified platform. Each ion pump can be programmed to deliver different ions with spatiotemporal control, providing both precision for individual ion delivery and versatility for multiple ion types through the same device architecture.
2Manufacturing precision
If spatial and temporal control is implemented for ion delivery, then accuracy of therapy delivery is improved, but device complexity increases
Solution Approach 1:
The system employs dynamic control where the ion delivery parameters (concentration, timing, location) can be adjusted in real-time based on wound healing feedback. The ion pumps are programmed to modify delivery patterns dynamically, achieving high accuracy while managing complexity through adaptive rather than statically complex design.
Solution Approach 2:
A feedback mechanism is integrated where wound healing progress is monitored and used to adjust ion delivery parameters. This closed-loop control system improves therapy accuracy by adapting to actual healing rates, while the feedback-based approach manages complexity more efficiently than purely pre-programmed complex systems.
3Adaptability or versatility
If multiple independent ion pumps are used to deliver different ionic species, then versatility of therapy is improved, but device complexity increases
Solution Approach 1:
Multiple ion pumps are integrated into a single wearable device unit that can be applied to the wound site. The pumps share common control electronics, power management, and housing structures, merging multiple functional components into a unified device that provides versatility without proportionally increasing overall complexity.
