Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If medical devices include sensors to collect data, then useful information is obtained, but the devices lack capacity to process and store the data efficiently
Solution Approach 1:
The patent extracts the data storage function from the medical device itself and places it in a separate portable memory device. The medical device only performs sensing and data transfer, while the portable device handles storage, reducing the processing and storage burden on the medical device.
Solution Approach 2:
The portable memory device acts as an intermediary between the medical device and external systems. It receives data via NFC from the medical device, stores it locally, and can later transfer it to external devices, serving as a buffer that resolves the storage capacity limitation.
2Ease of operation
If sensor data is transferred to external devices like smartphones, then data processing is enabled, but convenience is reduced due to availability or battery issues
Solution Approach 1:
The portable memory device serves itself by providing local storage capability. Data is captured and stored independently without requiring immediate connection to external devices, making the system self-sufficient and eliminating dependency on external device availability or battery status during data collection.
Solution Approach 2:
The portable device performs preliminary data storage before any external transfer occurs. By capturing and storing data locally first, it ensures data is preserved regardless of whether external devices are available or have sufficient battery, enabling reliable later transfer when conditions are favorable.
3Adaptability or versatility
If a portable memory device with battery and NFC transceiver is used, then data capture and storage is enabled, but device complexity increases
Solution Approach 1:
The portable memory device is designed as a multi-functional unit that combines NFC communication, wireless power reception, local storage, and data transfer capabilities in a single device. This universal design consolidates multiple functions into one device rather than requiring separate components for each function.
Solution Approach 2:
The portable memory device embeds multiple functional components (NFC transceiver, battery, memory storage, processing unit) within a compact form factor. The nested arrangement of these components allows the device to perform multiple functions while maintaining portability and manageable complexity.
