Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fluidic components are integrated into patch pumps to achieve proper fluid delivery, then fluid delivery function is improved, but device complexity increases
Solution Approach 1:
The patent combines the pressure sensor and micropump into a single integrated device, where the pressure sensor is positioned to detect pressure within the micropump chamber. This merging eliminates the need for separate pressure sensing components and fluidic connections, thereby reducing device complexity while maintaining reliable fluid delivery function through direct pressure monitoring within the pump itself.
2Reliability
If multiple fluidic components are integrated into patch pumps, then fluid delivery function is improved, but device size increases
Solution Approach 1:
The integration of the pressure sensor directly with the micropump structure allows the sensor to occupy space within or adjacent to the pump chamber rather than requiring separate housing and connection components. This merging significantly reduces the overall device volume while ensuring proper fluid delivery through direct pressure detection at the source.
3Reliability
If multiple fluidic components are integrated into patch pumps, then fluid delivery function is improved, but manufacturing cost increases
Solution Approach 1:
The integrated design combining pressure sensor and micropump reduces the number of discrete components that need to be sourced, assembled, and tested. This consolidation simplifies the manufacturing process, reduces assembly steps, and lowers overall manufacturing cost while maintaining the reliability of fluid delivery function through direct pressure monitoring within the pump chamber.
