Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are used to receive signals of different wireless communication protocols, then signal reception accuracy is maintained, but device size and cost increase
Solution Approach 1:
The patent combines multiple antenna functions into a single antenna by using a switch circuit to selectively connect the antenna to different receiving circuits based on the communication protocol being received. This merging approach maintains signal reception accuracy for multiple protocols while reducing the physical number of antennas required, thereby decreasing device size.
Solution Approach 2:
The single antenna is designed to serve multiple communication protocols simultaneously through the switch circuit's ability to route the antenna connection to different receiving circuits (first receiving circuit for first protocol, second receiving circuit for second protocol). This multi-functional design allows one antenna to replace what would traditionally require multiple specialized antennas.
2Reliability
If multiple antennas are used to receive signals of different wireless communication protocols, then signal reception accuracy is maintained, but manufacturing cost increases
Solution Approach 1:
By merging the functionality of multiple antennas into a single antenna with selective switching, the patent reduces the bill of materials and assembly complexity. The switch circuit enables one antenna to perform the work of multiple antennas, directly reducing component count and manufacturing cost while maintaining the ability to receive multiple protocols accurately.
3Area of stationary object
If a single antenna is used to receive multiple communication signals, then device size and cost are reduced, but signal reception accuracy may deteriorate
Solution Approach 1:
The patent introduces dynamic switching capability through the switch circuit, which dynamically connects the single antenna to the appropriate receiving circuit based on which communication protocol is currently being received. This dynamic adaptation ensures that the antenna is optimally connected for each protocol, maintaining signal reception accuracy despite using only one antenna physically.

AI summary
A signal receiving method, comprising: receiving a first communication signal and/or a second communication signal through an antenna; when the antenna receives the first communication signal and the second communication signal simultaneously, transmitting, by a first receiving circuit, the first communication signal to a first amplifying circuit, and receiving the second communication signal by a second receiving circuit; and When the antenna does not receive the first communication signal and the second communication signal simultaneously, transmitting, by the first receiving circuit, the first communication signal to the first amplifying circuit, and transmitting, by the first receiving circuit, the second communication signal to a second amplifying circuit. The first communication signal and the second communication signal correspond to different communication protocols respectively.
