Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If antenna in package (AiP) structures are used to reduce size and improve integration, then device size and integration are improved, but device portability and functionality are limited due to increased package size and form factor
Solution Approach 1:
The transmitting and receiving components are divided into multiple groups (first group and second group for transmitting, multiple receiving components) that can operate independently in different modes (beamforming and MIMO). This segmentation allows the system to achieve both compact integration and enhanced functionality by distributing components across different spatial locations rather than consolidating them into a single large package.
Solution Approach 2:
The patent introduces a non-parallel arrangement between transmitting and receiving components, where the imaginary line through transmitting component centers is nonparallel to the imaginary line through receiving component centers. This dimensional reconfiguration optimizes signal paths and enables both beamforming and MIMO operations within a compact form factor, resolving the contradiction between small size and high functionality.
2Ease of manufacture
If transmitting and receiving components are aligned in parallel configuration, then manufacturing and assembly are simplified, but signal transmission efficiency and detection precision are reduced
Solution Approach 1:
The patent deliberately employs an asymmetric, non-parallel configuration where the imaginary line passing through the geometry centers of transmitting components is nonparallel to the imaginary line passing through the geometry centers of receiving components. This asymmetric arrangement optimizes signal transmission paths and enhances signal resolution by improving the geometric relationship between transmitting and receiving elements, thereby resolving the contradiction between manufacturing simplicity and signal precision.
3Measurement precision
If multiple transmitting components are used to enhance signal coverage and resolution, then detection precision and signal coverage are improved, but device complexity and size increase
Solution Approach 1:
The patent implements dynamic operational modes where transmitting components can switch between beamforming mode (using first group) and MIMO mode (using second group). This dynamic configurability allows the system to adapt to different operational requirements, achieving high signal resolution and coverage when needed while maintaining lower complexity for standard operations, thus resolving the contradiction between precision and complexity.
Solution Approach 2:
The transmitting components are designed with multi-functionality, where the same physical components can operate in different modes (beamforming and MIMO) depending on the operational requirements. This universal design allows a single set of components to provide both high-resolution detection and broad coverage without requiring separate dedicated components for each function, thereby reducing overall device complexity.
