Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless sensors are used to eliminate wires, then patient movement freedom is improved, but configuration complexity increases for non-technical staff
Solution Approach 1:
The wireless sensor automatically pairs with the monitoring device by detecting visual signals from the display and transmitting confirmation signals, eliminating the need for manual configuration by non-technical staff. The sensor performs pairing operations autonomously through its optical detector and processor.
Solution Approach 2:
The patent uses visual signals as an intermediary medium to facilitate pairing between the wireless sensor and monitoring device. The display generates visual signals that the sensor's optical detector interprets, creating a simple communication bridge that requires no technical knowledge from users.
2Reliability
If manual pairing configuration is required, then device compatibility is ensured, but pairing time and error rate increase
Solution Approach 1:
The wireless sensor is pre-configured with an optical detector and processor that automatically detect visual signals and establish pairing. The sensor enters pairing mode automatically when activated, eliminating the need for manual configuration steps and reducing pairing time while ensuring accuracy through automated signal verification.
Solution Approach 2:
The system implements feedback through confirmation signals transmitted from the wireless sensor to the monitoring device, indicating successful pairing. This feedback mechanism ensures reliable connection establishment and allows the system to verify pairing accuracy automatically, reducing errors associated with manual configuration.
3Ease of operation
If visual signal detection is used for pairing, then pairing simplicity is improved, but detection range requirements increase
Solution Approach 1:
The optical detector on the wireless sensor is positioned and oriented to detect visual signals from the display within a localized range during the pairing process. The display generates visual signals at a specific location, creating a focused detection zone that simplifies the pairing interaction while maintaining adequate detection range for the intended use scenario.
