Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional iontophoresis systems are used, then drug delivery function is provided, but treatment time is prolonged and patient mobility is restricted
Solution Approach 1:
The system is divided into two independent modules: a reusable electronic dose controller and a disposable iontophoretic patch. This segmentation allows the patch to be pre-prepared and applied to the patient, enabling treatment to continue uninterrupted while the controller is removed for mobility, thus reducing overall treatment time and improving efficiency.
Solution Approach 2:
The iontophoretic patch is pre-assembled with electrodes, drug reservoirs, and adhesive layers before patient application. This preliminary preparation eliminates setup time during treatment and allows the patient to receive immediate therapy upon application, reducing total treatment time.
2Productivity
If traditional iontophoresis systems are used, then drug delivery is achieved, but device complexity increases
Solution Approach 1:
The complex electronic dose control circuitry is extracted from the disposable patch and placed in a separate reusable controller. This extraction simplifies the patch design to basic electrochemical components, making it easier to manufacture and dispose, while the complex control functions are maintained in the durable controller.
Solution Approach 2:
The reusable electronic dose controller is designed to work with multiple different disposable patches for various drugs and treatment protocols. This multi-functionality reduces the need for multiple specialized devices, simplifying the overall system while maintaining high drug delivery efficiency through precise electronic control.
3Reliability
If single-use disposable patches are implemented, then safety and hygiene are improved, but manufacturing cost increases
Solution Approach 1:
The system separates the disposable single-use patch from the reusable controller. The patch contains only simple, low-cost components (electrodes, adhesive, drug reservoir) that are inexpensive to manufacture in large volumes, while the expensive electronic components are reused across multiple patients through the durable controller.
Solution Approach 2:
The patch is designed as a simple, inexpensive, single-use component that can be mass-produced at low cost using basic manufacturing processes. Its simplicity (without complex electronics) makes it economically viable as a disposable item, ensuring patient safety through elimination of cross-contamination while controlling manufacturing costs.
4Ease of operation
If on-board power sources are integrated into the patch, then independence from external power is achieved, but patch size and weight increase
Solution Approach 1:
The power source function is extracted from the disposable patch and placed in the reusable controller. This extraction allows the patch to remain extremely lightweight and thin, while the controller houses the batteries and power management circuitry, providing independent power supply without burdening the patient with heavy patch components.
