Engineering Contradiction Analysis
1Area of moving object
If the frame is narrowed to increase display area, then the appearance modernity and display area are improved, but the antenna arrangement space is reduced and communication quality deteriorates
Solution Approach 1:
The patent combines the antenna module with the circuit board by making the circuit board itself serve as the antenna structure. The circuit board's ground layer and signal layers are configured to function as antenna elements, eliminating the need for separate antenna components and freeing up space that was previously occupied by dedicated antenna modules.
Solution Approach 2:
The circuit board is designed to perform multiple functions simultaneously: it serves as the structural support for electronic components, the grounding reference plane, the signal transmission pathway, and the antenna radiation structure. This multi-functionality reduces the overall component count and optimizes space utilization within the narrow frame.
2Reliability
If an electromagnetic wave inductor is arranged near the antenna to adjust electromagnetic wave energy, then the electromagnetic wave control is improved, but the antenna arrangement space is further reduced
Solution Approach 1:
The inductor elements are integrated directly into the circuit board's layered structure, where they share the same physical space with the antenna elements. The inductors are formed using the circuit board's conductive layers and are positioned to interact with the electromagnetic fields generated by the antenna, eliminating the need for separate inductor components.
Solution Approach 2:
The inductor structures are nested within the multi-layer circuit board construction, utilizing the vertical stacking of conductive layers. The inductors are formed by routing conductive traces through multiple layers of the circuit board, creating compact inductive elements that occupy minimal space while maintaining their electromagnetic functionality.
3Adaptability or versatility
If separate components are used for key module, sensing module, and antenna module, then the functional independence is improved, but the device complexity and space occupation increase
Solution Approach 1:
The circuit board is designed to simultaneously host multiple functional modules: the key input module uses the circuit board as its sensing surface, the proximity sensing module uses the circuit board as its induction conductor, and the antenna module uses the circuit board as its radiation structure. Each module maintains its functional independence through specific circuit connections while sharing the common circuit board substrate.
Solution Approach 2:
The patent merges multiple functional modules into a unified circuit board structure. The key module, sensing module, and antenna module are integrated by configuring different regions and layers of the same circuit board to perform different functions, reducing the overall component count and simplifying the device architecture.
