Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna modules are arranged in the electronic device, then radiation performance is improved, but arrangement space becomes insufficient
Solution Approach 1:
The patent transitions from a conventional planar arrangement to a three-dimensional spatial configuration by inclining the antenna module at a specific angle (α) relative to the printed circuit board. This dimensional change allows the antenna module to occupy unused vertical and angular space within the device housing, thereby improving radiation performance without consuming additional planar arrangement space.
Solution Approach 2:
The antenna module is nested within the limited internal space of the electronic device by positioning it at an incline between the side surface and the camera module. This nesting approach allows the antenna module to utilize the void space created by the camera module's offset from the side surface, effectively packing multiple components into the available volume without interference.
2Reliability
If multiple antenna modules are arranged in the electronic device, then radiation performance is improved, but noise increases due to increased FPCB length
Solution Approach 1:
By inclining the antenna module in three-dimensional space, the patent shortens the required length of the FPCB connecting the antenna module to the printed circuit board. The inclined configuration reduces the horizontal distance the FPCB must span, thereby minimizing noise and interference while still achieving the desired radiation performance through optimized spatial positioning.
3Reliability
If FPCB length is increased to connect antenna modules, then connectivity is ensured, but noise and interference increase
Solution Approach 1:
The patent optimizes the FPCB length by changing the spatial parameters of the antenna module arrangement. By adjusting the inclination angle and positioning of the antenna module, the FPCB length is minimized to an optimal value that ensures reliable electrical connectivity while reducing the FPCB's susceptibility to noise and interference from other components.

AI summary
An electronic device includes a support member and a lateral member extending from the support member and defining a side surface, a circuit board on the support member and including a camera spaced apart from the side surface, a signal-radiating antenna electrically connected to the circuit board, and a flexible circuit board electrically connecting the circuit board to the signal-radiating antenna and including a flexible area and a rigid area. The support member further defines an inclined surface between the side surface and the camera, on which the signal-radiating antenna is disposed, the inclined surface forming a first inclined angle with respect to one surface of the support member, and a flexible circuit board support surface adjacent to the first inclined surface along which a length of the flexible circuit board extends, the flexible circuit board support surface forming a second inclined angle with respect to one surface of the support member.
