Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the antenna is disposed on the display panel to reduce space, then the device becomes thinner and lighter, but the construction of coaxial circuits becomes difficult and sensitivity is lowered
Solution Approach 1:
The antenna system is segmented into multiple independent radiation units (first, second, and third radiation units), each with its own radiator and transmission line. This segmentation allows each unit to be optimized for specific signal directions without requiring complex coaxial circuits, thereby maintaining sensitivity while reducing overall device weight and space requirements.
Solution Approach 2:
The patent transitions from traditional three-dimensional coaxial circuit structures to a two-dimensional planar configuration where transmission lines are disposed on the same layer as radiators. This dimensional change eliminates the need for complex vertical interconnections, reducing device thickness and weight while maintaining effective signal coupling and sensitivity.
2Volume of moving object
If the antenna is disposed on the display panel to save space, then the device becomes more compact, but the construction of coaxial power supply circuits becomes difficult
Solution Approach 1:
The patent employs a planar two-dimensional configuration where transmission lines and radiators are disposed on the same layer, eliminating the need for complex three-dimensional coaxial circuit construction. This approach significantly simplifies manufacturing processes while effectively utilizing the limited space on the display panel.
Solution Approach 2:
The patent replaces traditional mechanical coaxial circuit structures with an integrated planar transmission line system that can be manufactured using standard thin-film deposition and patterning techniques. This substitution eliminates complex assembly steps and makes the antenna structure compatible with conventional display panel manufacturing processes.
3Reliability
If multiple radiators are used to improve signal detection in multiple directions, then signal efficiency improves, but device complexity increases
Solution Approach 1:
The antenna system is divided into multiple independent radiation units, each responsible for detecting signals from specific directions. This segmentation enables multi-directional signal detection capability while keeping each individual unit relatively simple in structure, thereby improving overall detection accuracy without proportionally increasing complexity.
Solution Approach 2:
Each radiation unit is designed with universal characteristics that allow it to function independently while contributing to the overall multi-directional detection capability. The parallel feeding configuration provides a universal solution for exciting multiple radiators simultaneously, simplifying the control architecture despite having multiple radiating elements.
