Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional rigid antenna structures are used, then manufacturing precision is improved, but device flexibility and space utilization deteriorate
Solution Approach 1:
The patent uses flexible substrates to carry the antenna structure, replacing traditional rigid PCB boards. This allows the antenna to be folded or bent to fit different device configurations while maintaining electrical connectivity and radiation performance, directly resolving the contradiction between manufacturing precision and device flexibility.
Solution Approach 2:
The patent introduces a vertical stacking dimension by placing multiple antenna radiation plates at different heights (first antenna radiation plate, second antenna radiation plate separated by distance d). This three-dimensional arrangement increases space utilization and allows high-speed data transmission without requiring large planar areas, thus improving adaptability while maintaining precision.
2Speed
If larger antenna structures are used for high-speed data transmission, then transmission speed is improved, but device size increases
Solution Approach 1:
The patent transitions from planar antenna design to three-dimensional stacked antenna structure. Multiple radiation plates are arranged vertically with spacing d, enabling high-speed data transmission through increased antenna gain and bandwidth without proportionally increasing the device's footprint area.
Solution Approach 2:
The antenna structure embeds multiple radiation plates within a compact vertical space. The first and second antenna radiation plates are nested in the vertical dimension, allowing the antenna system to achieve high transmission speed performance while occupying minimal horizontal space within the device.
3Volume of moving object
If foldable antenna structures are used, then space utilization is improved, but structural stability deteriorates
Solution Approach 1:
The flexible substrate provides both the necessary flexibility for folding and sufficient mechanical strength to maintain structural integrity. The substrate's material properties are optimized to allow repeated bending while maintaining electrical connectivity and antenna performance stability.
Solution Approach 2:
The patent combines multiple functional layers (flexible substrate, antenna radiation plates, control chip, shielding layer) into an integrated radio frequency circuit module. This unified structure enhances overall stability while maintaining foldability, as the layers work together as a cohesive unit rather than separate components.

AI summary
A wireless communication device includes an antenna module and a flexible substrate. The antenna module includes an antenna structure and a control chip. The control chip is configured to use an antenna structure to perform wireless communication. The flexible substrate is used to carry the antenna module and includes two substrate regions. The antenna structure includes a first antenna radiation plate and a second antenna radiation plate. An open slot is extended from an edge of the first antenna radiation plate to a center of the first antenna radiation plate. The second antenna radiation plate is disposed under the first antenna radiation plate to overlap the first antenna radiation plate. There is a distance between the first antenna radiation plate and the second antenna radiation plate, thus the second antenna radiation plate is coupled to the first antenna radiation plate.
