Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are integrated into the base plate to detect adhesive failure and leakage, then monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the adhesive layer and sensor layer into a single integrated base plate structure. The sensor layer is positioned between the adhesive layer and the backing layer, allowing the base plate to simultaneously provide adhesive functionality and sensing capability without requiring separate components.
Solution Approach 2:
The base plate is designed to perform multiple functions: providing adhesive attachment to the skin, supporting the sensor layer for monitoring, and maintaining structural integrity. This multi-functionality reduces the need for additional separate components.
2Measurement precision
If multiple layers including electrode assembly are added to the base plate, then sensing capability is improved, but manufacturing complexity increases
Solution Approach 1:
The base plate is divided into distinct functional layers: an adhesive layer for skin attachment, a sensor layer containing electrodes for measuring electrical quantities, and a backing layer for structural support. This segmentation allows each layer to be optimized independently while simplifying the overall manufacturing process.
Solution Approach 2:
The sensor layer with electrodes is pre-assembled between the adhesive and backing layers during base plate fabrication, rather than being added separately after assembly. This preliminary integration streamlines the manufacturing process and ensures proper positioning of the sensing components.
