Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional antenna pattern is used on the PCB, then the beam pattern is generated in the vertical direction to the antenna plane, but this prevents face-to-face communication between laterally adjacent battery packs
Solution Approach 1:
The patent inverts the conventional antenna design by positioning the antenna pattern along the edge of the PCB rather than in the center, and orienting it to generate beam patterns in the lateral direction instead of the vertical direction. This inversion enables face-to-face communication between laterally adjacent battery packs, directly resolving the contradiction between conventional beam orientation and communication adaptability requirements.
Solution Approach 2:
The patent changes the dimensional orientation of the antenna pattern from a vertical beam generation (perpendicular to PCB surface) to a lateral beam generation (parallel to PCB surface). By repositioning the antenna along the edge and adjusting its orientation, the beam pattern is redirected into a different spatial dimension, enabling communication between adjacent battery packs in the lateral direction.
2Adaptability or versatility
If the antenna pattern is extended to cover the entire edge circumference, then the beam pattern coverage is maximized, but the antenna pattern area and design complexity increase
Solution Approach 1:
The patent applies local quality by positioning the antenna pattern specifically along the edge region of the PCB where communication with adjacent battery packs is needed. Rather than distributing antenna elements across the entire PCB surface, the antenna is concentrated at the edge, providing targeted beam coverage in the lateral direction while minimizing the overall antenna pattern area and reducing design complexity.

This configuration allows for effective edge-to-edge communication between horizontally arranged battery packs, reducing design costs and time by minimizing the antenna pattern area on the PCB.
Implementation Method 1

AI summary
The present invention relates to a PCB adopting an edge antenna which designs an antenna pattern in an edge region of the PCB to generate a beam pattern generated from the antenna pattern not in a vertical direction to an antenna plane but in a lateral direction of the PCB, thereby enabling face-to-face communication between large-area battery packs laterally adjacent to each other, and a battery including the PCB adopting the edge antenna.
