Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the antenna is simply connected to the radio communication module, then the structure is simple and easy to manufacture, but the antenna may be separated from the radio communication module when abnormal impact is applied
Solution Approach 1:
The connector is divided into a receiving connector fixed to the printed circuit board and a transmitting connector attached to the antenna cable. The transmitting connector includes a cable fixing part that separately secures the cable through a clamping mechanism, while the receiving connector provides the electrical connection interface. This segmentation allows independent optimization of connection security and manufacturing simplicity.
Solution Approach 2:
The cable fixing part of the transmitting connector preliminarily secures the cable before final assembly. The clamping structure is pre-configured to grip the cable, and the transmitting connector is designed with built-in cable fixation features that prevent detachment before the connector is even installed on the receiving connector.
2Reliability
If protrusion and groove coupling is used in the antenna connector and RF cable connector, then the antenna detachment is prevented, but the device complexity increases
Solution Approach 1:
The cable fixing function and the electrical connection function are merged into a single transmitting connector assembly. The clamping structure for cable fixation and the contact pins for electrical connection are integrated in one component that attaches to the antenna cable, eliminating the need for separate coupling mechanisms.
Solution Approach 2:
The transmitting connector includes a self-clamping mechanism where the clamping structure automatically grips the cable when the connector is assembled. The elastic deformation of the clamping arms provides automatic cable securing without requiring additional fastening steps or complex adjustment mechanisms.
3Reliability
If a hole is drilled in the printed circuit board and the cable is soldered, then the antenna detachment is prevented, but workability is significantly decreased and additional processes are required causing cost increase
Solution Approach 1:
The mechanical soldering and cable threading process is replaced with a mechanical clamping system. Instead of drilling holes and soldering cables to the PCB, the transmitting connector uses elastic clamping arms that mechanically grip the cable, providing equivalent or superior fixation without requiring thermal processes or precise hole alignment.
Solution Approach 2:
The transmitting connector acts as an intermediary component between the antenna cable and the printed circuit board. It provides the cable fixation function that was previously achieved through PCB modification, while also providing the electrical connection interface, thereby eliminating the need for direct cable-to-PCB soldering.
4Object-affected harmful factors
If the shield can is added for electromagnetic shielding, then the electromagnetic wave shielding is improved, but the device complexity increases
Solution Approach 1:
The shield can serves multiple functions: it provides electromagnetic shielding for the radio communication module circuits, acts as a structural support for mounting the receiving connector, and provides a ground reference for the RF signals. By combining these functions into a single component, the overall device complexity is minimized while achieving comprehensive shielding.

AI summary
There is provided a radio communication module. The radio communication module includes a printed circuit board including a receiving connector, a shield can provided on the printed circuit board and shielding an electromagnetic wave, and an antenna including a transmitting connector connected to the receiving connector and connected to the printed circuit board through the transmitting connector. In addition, the shield can includes a blocking part formed at one side surface thereof and protruding toward the transmitting connector and the receiving connector. Therefore, detachment of the transmitting connector connected to the receiving connector is prevented to prevent separation of the antenna, thereby making it possible to effectively prevent deterioration of performance.
