Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electronic devices are made smaller and more integrated, then device compactness and integration are improved, but antenna arrangement and wireless communication capability deteriorate
Solution Approach 1:
The support plate is designed to serve dual functions: providing structural support for the printed circuit board and acting as an antenna for wireless communication. This multi-functionality allows the device to maintain compact size while ensuring adequate antenna capability for multiple frequency bands and communication protocols.
Solution Approach 2:
The patent combines the support plate structure with antenna functionality by configuring specific portions of the support plate to serve as radiating elements. This merging of structural and communication functions eliminates the need for separate antenna components, thereby maintaining device compactness while ensuring wireless communication capability across multiple frequency bands.
2Adaptability or versatility
If multiple antennas are added for additional frequency bands, then communication versatility is improved, but device complexity and space requirements worsen
Solution Approach 1:
The support plate is configured with multiple distinct antenna portions, each capable of operating in different frequency bands. This allows a single structural component to provide multi-band wireless communication functionality, avoiding the need for multiple separate antenna assemblies and thereby reducing device complexity while maintaining frequency band versatility.
Solution Approach 2:
The support plate is divided into multiple functionally distinct antenna portions (first antenna portion, second antenna portion, etc.), each optimized for specific frequency bands or communication protocols. This segmentation within a unified structure enables multi-band operation without requiring separate antenna components for each frequency band.
3Reliability
If traditional antenna structures are used, then antenna performance is improved, but electromagnetic interference between antennas worsens
Solution Approach 1:
Different portions of the support plate are configured with distinct antenna designs and orientations optimized for specific frequency bands and communication protocols. This local differentiation in antenna quality and configuration reduces electromagnetic interference between antennas operating in different bands while maintaining optimal performance for each communication function.
