Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the antenna is formed independently outside the circuit board, then the antenna can be connected via electrical pads or conductive wires, but the antenna occupies additional space
Solution Approach 1:
The antenna is merged with the circuit board by forming it on the surface of the circuit board using conductive patterns. This integration eliminates the need for separate antenna components and their connecting wires, thereby reducing the occupied space while maintaining ease of manufacture through standard PCB fabrication processes
Solution Approach 2:
The circuit board serves dual functions: as the structural support for electronic components and as the substrate for the antenna. The conductive patterns on the circuit board perform both electrical connection functions and antenna radiation functions, reducing the need for additional components and space
2Device complexity
If a single antenna is used, then the device structure is simple, but the antenna cannot radiate wireless signal beams in arbitrary directions
Solution Approach 1:
The antenna system is segmented into multiple independent antenna elements (first antenna, second antenna, third antenna, fourth antenna) arranged in a specific geometric pattern on the circuit board. Each element can be independently controlled to radiate signals, and by adjusting the phase and amplitude of each element, the radiation beam can be steered in arbitrary directions without mechanical movement
Solution Approach 2:
The patent transitions from a single-point antenna to a distributed array of antenna elements across two-dimensional space on the circuit board. This spatial distribution enables beam forming and direction control through phase manipulation of signals from different elements, adding the dimension of spatial control to the radiation pattern
