Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate antenna and touch-sensing components are used, then signal reliability is improved, but device space consumption increases
Solution Approach 1:
The patent combines the antenna component and touch-sensing component into a single integrated structure where the sensing layer serves dual purposes: as part of the antenna radiating body and as the touch-sensing element. This merging eliminates the need for separate components, reducing overall device space while maintaining functional performance of both antenna and touch-sensing operations
2Area of stationary object
If antenna and touch-sensing components are integrated, then device space is reduced, but signal interference occurs
Solution Approach 1:
The patent introduces a feeding structure as an intermediary element that physically and electrically connects the antenna component and touch-sensing component. This feeding structure acts as a mediator that separates the signal paths, allowing RF signals to be transmitted to the antenna while preventing touch-sensing signals from interfering with antenna operation, thus eliminating mutual interference in the integrated design
3Adaptability or versatility
If multiple antennae are used for various frequencies, then communication capability is improved, but layout complexity increases
Solution Approach 1:
The integrated antenna component is designed with multi-functional capability to operate across multiple frequency bands (e.g., 700MHz, 800MHz, 900MHz, 1800MHz, 2100MHz, 2600MHz). By making the antenna universal rather than requiring separate dedicated antennas for each frequency, the patent simplifies the overall layout while maintaining comprehensive communication capability across different wireless standards

AI summary
A wireless communication device that has a circuit board, an RF signal module, a capacitive touch-sensing component and an antenna component is provided. The touch-sensing signal module is disposed on the circuit board. The capacitive touch-sensing component includes a sensing layer and a ground layer. The sensing layer is electrically connected to the touch-sensing signal module. The antenna component includes a feed point and a radiating body. The feed point is disposed on the ground layer and is electrically connected to the RF single module. The radiating body incorporates at least parts of the ground layer. Alternatively, the feed point is disposed on the sensing layer, and the radiating body incorporates at least parts of the sensing layer. Therefore, the radiating body is incorporated into the sensing layer or ground layer of the capacitive touch-sensing component and can save accommodating space.
