Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple medical electrodes are applied separately, then each electrode can be individually positioned, but the accuracy and consistency of electrode placement deteriorates and the application process becomes time-consuming
Solution Approach 1:
Multiple medical electrodes are merged into a single integrated assembly with a common base structure. The base holds multiple electrodes in predetermined positions, allowing simultaneous application to the patient's body. This eliminates the need to apply each electrode separately while maintaining placement accuracy through the pre-configured geometric arrangement of electrodes on the base.
Solution Approach 2:
The electrodes are pre-positioned on the base structure during manufacturing with precise geometric relationships established beforehand. This preliminary positioning ensures that when the assembly is applied to the patient, the electrodes are automatically placed at the correct locations and orientations without requiring individual adjustment during the application process.
2Reliability
If multiple medical electrodes are applied separately, then each electrode can be individually handled, but the consistency in attachment and adhesion deteriorates
Solution Approach 1:
Multiple electrodes are combined into a single assembly with a common base that provides uniform attachment characteristics. The base structure ensures consistent adhesion across all electrodes when applied to the patient's body or medical device, eliminating variability that occurs when electrodes are applied individually by different handlers or at different times.
Solution Approach 2:
The base structure provides a uniform substrate for all electrodes, ensuring homogeneous attachment properties across the entire assembly. All electrodes share the same adhesive interface with the base and the same geometric relationship to it, creating consistent attachment behavior throughout the assembly regardless of which specific electrode is being applied.
3Productivity
If each medical electrode is packaged separately, then each electrode can be independently stored and handled, but the process of peeling off liners becomes time-consuming and inconvenient
Solution Approach 1:
Multiple electrodes are packaged together in a single integrated unit with a common protective covering or liner that can be removed as one piece. This merging of packaging structures eliminates the need to individually peel and handle separate liners for each electrode, significantly reducing the time and effort required for preparation while maintaining protection of all electrodes during storage and transport.
