Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery is integrated into the disposable base, then reliable power supply is achieved, but device complexity increases
Solution Approach 1:
The system is divided into a disposable base containing the battery and sensor, and a reusable sensor electronics module. This segmentation allows the battery to be reliably integrated into the disposable portion while keeping the complex electronics reusable, thus maintaining power supply reliability without permanently increasing overall device complexity.
Solution Approach 2:
The battery is integrated into the disposable base rather than the reusable module. This allows the battery to be replaced automatically when the base is discarded, ensuring reliable power supply without requiring complex battery management in the reusable portion of the device.
2Reliability
If a sealing member is added to protect contacts, then reliability of electrical connection is improved, but device complexity increases
Solution Approach 1:
The sealing member integrates multiple functions: it seals the interface between the disposable base and reusable module, protects the electrical contacts from moisture and contamination, and maintains the water-tight barrier. By combining these functions into a single component, the sealing member improves electrical connection reliability without proportionally increasing device complexity.
3Stability of the object's composition
If a disposable base with integrated battery is used, then power supply consistency is improved, but manufacturing complexity increases
Solution Approach 1:
The system separates the battery-containing disposable base from the reusable electronics module. This segmentation allows each component to be manufactured and tested independently, simplifying the overall manufacturing process while ensuring consistent power supply from the dedicated battery in the disposable portion.
4Loss of substance
If a reusable sensor electronics module is used, then waste is reduced, but initial device complexity increases
Solution Approach 1:
The reusable sensor electronics module is designed to be detached from the disposable base and reused with new bases. This allows the complex electronic components to be recovered and reused multiple times, reducing waste while accepting that the overall system complexity increases due to the modular reusable component.
