Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate battery and pad configuration is used, then the microcurrent patch can be assembled, but the device becomes bulky and inconvenient to use
Solution Approach 1:
The patent combines the battery, circuit, and pad into a single integrated structure where the battery and circuit are disposed on the base and covered with a glue layer to form one unified device, eliminating the need for separate assembly and reducing overall device volume
2Reliability
If metal electrodes are used to generate microcurrent through interaction with body fluid, then current generation is achieved, but flexibility is remarkably reduced
Solution Approach 1:
The patent uses a flexible base structure with a glue layer covering the battery and circuit, replacing rigid metal electrodes while maintaining current generation capability through the flexible configuration that can conform to body surfaces
Solution Approach 2:
The glue layer serves as an intermediary between the circuit and the body fluid, enabling current generation through the flexible adhesive material rather than through rigid metal electrodes, thus maintaining both flexibility and electrical functionality
3Power
If the circuit is made with larger linear width, then current flow is increased, but the ability to control current amount is reduced
Solution Approach 1:
The patent creates different regions in the circuit with different linear widths, allowing specific areas to have higher current flow while maintaining overall control capability through the varied width design that can be adjusted for different current requirements
4Ease of operation
If the patch is made rigid for structural stability, then manufacturing is easier, but the patch cannot be easily attached to curved human bodies
Solution Approach 1:
The patent employs a flexible base and glue layer configuration that allows the patch to conform to curved body surfaces while maintaining a simple manufacturing process through the use of flexible materials that can be easily assembled
