Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixed hardware configuration is used, then device simplicity is maintained, but system reliability deteriorates due to inability to replace abnormal signal processing units
Solution Approach 1:
The patent implements dynamic reconfiguration capability by introducing switch arrays that can change the coupling relationships between controller and signal processing units in real-time. The controller can dynamically switch between normal signal processing units and backup units based on detected abnormality states, transforming the traditionally fixed hardware configuration into a dynamic, adaptable system that improves reliability without permanent complexity increase.
Solution Approach 2:
The patent changes the operational parameters of the system by introducing multiple signal processing units with identical functional parameters but different operational states. When an abnormality is detected in one unit, the system changes the coupling parameter (connection state) to switch to a backup unit, maintaining system functionality through parameter substitution rather than structural redesign.
2Measurement precision
If open loop design is used, then control simplicity is maintained, but monitoring capability deteriorates due to inability to detect signal quality of each unit
Solution Approach 1:
The patent implements feedback mechanisms by having the controller receive output signals from signal processing units and compare them against expected signals to generate detection results. This closed-loop feedback enables the controller to monitor the operational state and signal quality of each unit, identifying abnormal states and triggering appropriate switching actions to maintain system reliability.
Solution Approach 2:
The patent introduces switch arrays as intermediary components between the controller and signal processing units. These intermediaries enable the controller to selectively couple with different units based on their operational state, providing a mechanism for monitoring and controlling signal quality without requiring direct complex interaction with each unit.
3Adaptability or versatility
If no backup units are provided, then device complexity is reduced, but adaptability deteriorates due to inability to substitute abnormal units
Solution Approach 1:
The patent applies preliminary action by pre-configuring backup signal processing units that remain in standby state, ready to replace abnormal units when needed. The switch arrays are pre-configured with multiple coupling paths, allowing immediate substitution without requiring complex real-time decision-making or system reconfiguration when an abnormality occurs.
Solution Approach 2:
The patent implements copying by creating duplicate signal processing units with identical functional capabilities. The backup units are copies of the normal units, allowing seamless substitution when an abnormality is detected. This copying strategy provides adaptability through redundancy without requiring fundamentally different architectural components.

AI summary
An electronic device and an operating method thereof are provided. The electronic device includes a first switch array, a second switch array, a first signal processor, and a controller. The first signal processor is coupled between the first and second switch arrays. The controller is coupled to the first and second switch arrays. The controller transmits an input signal to the first signal processor through the first switch array, and receives an output signal of the first signal processor through the second switch array. The controller determines whether the output signal is equal to an expected signal to generate a detection result. When the detection result is an abnormal state, the first switch array and the second switch array change the controller to be coupled to a backup signal processor.
