Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing calibration technologies use simulation circuits and time measurement apparatus, then circuit parameters such as voltages and currents can be simulated, but the wiring becomes complex and cannot simulate comprehensive test items
Solution Approach 1:
The calibration system is divided into multiple independent modules including power supply module, voltage output module, current output module, signal feedback module, control module, and display module. Each module performs a specific function and can be independently connected through standardized interfaces, eliminating complex wiring while maintaining comprehensive testing capability.
Solution Approach 2:
The calibration system integrates multiple functions into a single unified device that can simulate various circuit parameters (voltages, currents), measure action times, display operation statuses, and simulate different failure scenarios. This multi-functional integration replaces multiple separate calibration devices, simplifying the overall system while enhancing testing versatility.
2Device complexity
If debugging device uses two dual-position relays with magnetic latches, then simple structure is achieved, but multiple test items required by current BAS devices cannot be accomplished
Solution Approach 1:
The system replaces static relay-based switching with dynamic modular architecture where the control module can programmatically configure different test scenarios. This allows the system to adapt to various testing requirements (normal operation, failure scenarios, different circuit configurations) without requiring physical reconfiguration or additional hardware components.
Solution Approach 2:
The system uses virtual simulation of circuit behaviors through software control rather than physical replication of complex circuitry. The control module generates and processes signals that simulate various operating conditions and failure modes, eliminating the need for physical test circuits while maintaining comprehensive testing capability.
3Ease of operation
If testing apparatus claims simple wiring, then connection complexity is reduced, but specific wiring connection device is not disclosed and usage status cannot be displayed
Solution Approach 1:
The system incorporates a signal feedback module that continuously monitors the operation status of the BAS device under test and provides real-time feedback to the control module. This feedback is then displayed through the display module, allowing operators to view usage status, test results, and system states without additional measurement devices.
Solution Approach 2:
The control module serves as an intermediary that receives signals from the BAS device, processes the information, and communicates the status through the display module. This intermediary function integrates measurement and display capabilities within the calibration system itself, eliminating the need for separate status monitoring devices while maintaining simple wiring.
