Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the wireless communication module is designed with compact size, then portability and ease of carrying are improved, but antenna performance especially for low-frequency signals deteriorates due to insufficient space
Solution Approach 1:
The patent combines the main antenna in the wireless communication module with a supplementary antenna in the electronic device to form a cooperative antenna system. When the module is inserted into the socket, the two antennas become electromagnetically coupled and work together, allowing the compact module to achieve the performance of a larger antenna through collaboration with the device's supplementary antenna.
Solution Approach 2:
The socket serves as an intermediary structure that enables electromagnetic coupling between the main antenna and supplementary antenna. The socket's conducting portion acts as a mediator to establish the electromagnetic connection when the wireless communication module is inserted, facilitating the cooperative operation of the two antennas.
2Reliability
If the antenna size is increased to improve low-frequency signal transmission, then signal quality is improved, but the compact design of the wireless communication module is compromised
Solution Approach 1:
The patent extends the antenna system from a single-dimension compact antenna to a multi-dimensional cooperative system. The main antenna remains compact within the module, while the supplementary antenna in the electronic device provides additional radiating space, effectively increasing the overall antenna aperture without enlarging the module itself.
Solution Approach 2:
The patent merges the functionality of two separate antennas (main antenna in module, supplementary antenna in device) into a unified antenna system that operates together to provide enhanced signal quality, particularly for low-frequency signals that require larger effective aperture.
3Device complexity
If a single antenna is used in the compact module, then device complexity is reduced, but antenna gain is insufficient for effective wireless communication
Solution Approach 1:
The supplementary antenna in the electronic device serves multiple functions: it acts as a radiator when the wireless communication module is inserted, provides electromagnetic coupling medium through the socket, and can independently function as an antenna for other wireless communication purposes when the module is not present.
