Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed infrared receiver is used in the electronic device, then the device structure is simple, but the adaptability is poor and service life is short
Solution Approach 1:
The patent implements dynamic signal source selection by enabling the electronic device to automatically switch between internal wireless receiver and external wireless receiver connected via connector based on connection status. The control module detects whether an external receiver is connected and dynamically selects the appropriate signal source, transforming a static fixed-receiver structure into a dynamic adaptive system that adjusts to different usage scenarios.
Solution Approach 2:
The patent makes the electronic device's control system universal by designing it to accept signals from multiple types of wireless receivers (both internal and external). The control module is configured to process control signals from either the internal wireless receiver or an external wireless receiver connected through the connector, enabling the device to function with different receiver configurations and expanding its applicability across various use cases.
2Reliability
If an internal wireless receiver is permanently installed, then the device structure is simple, but the service life is reduced due to malfunction and inability to replace
Solution Approach 1:
The patent implements dynamic signal source selection by enabling the electronic device to automatically switch between internal wireless receiver and external wireless receiver connected via connector based on connection status. The control module detects whether an external receiver is connected and dynamically selects the appropriate signal source, transforming a static fixed-receiver structure into a dynamic adaptive system that adjusts to different usage scenarios.
Solution Approach 2:
The patent introduces a connector as an intermediary component that enables external wireless receivers to connect to the electronic device. This connector serves as a mediator between the internal control system and external receivers, allowing users to replace or upgrade receivers without modifying the internal device structure. The control module acts as another intermediary by managing the signal routing between different receivers and the control system.
3Adaptability or versatility
If multiple signal sources are supported, then adaptability is improved, but mis-operation may occur due to signal interference
Solution Approach 1:
The patent implements a feedback mechanism where the control module continuously monitors the connection status of external wireless receivers through the connector. Based on this feedback information, the control module automatically determines whether to prioritize signals from the internal or external receiver. This feedback-driven approach ensures that only one active signal source controls the device at any given time, preventing mis-operation caused by signal conflicts while maintaining adaptability to different receiver configurations.

AI summary
An electronic apparatus. The electronic apparatus comprises: a first connector (40), a data detection module (10), a data selector (20), and a first wireless receiving device (30). The data detection module (10) is electrically connected to a first output end (41) of the first connector (40) and a control end (23) of the data selector (20). A first input end (21) of the data selector (20) is electrically connected to a second output end (42) of the first connector (40), to receive a first signal from the first connector (40), and a second input end (22) of the data selector (20) is electrically connected to the first wireless receiving device (30), to receive a second signal from the first wireless receiving device (30). When an input end (43) of the first connector (40) is not suspended, the data selector (20) receives a control signal from the data detection module (10) as a first level signal, and an output end (24) of the data selector (20) outputs the first signal. When the input end (43) of the first connector (40) is suspended, the data selector (20) receives a control signal from the data detection module (10) as a second level signal, and the output end (24) of the data selector (20) outputs the second signal.
