Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antenna elements are utilized for beamforming, transmit diversity and MIMO configurations, then communication performance is improved, but device size and complexity increase
Solution Approach 1:
The patent combines multiple antenna elements into a single integrated waveguide structure. Instead of using separate physical antennas for beamforming, transmit diversity, and MIMO, the invention integrates these functions into one waveguide that can support multiple modes and polarizations, thereby reducing device size while maintaining communication performance.
Solution Approach 2:
The waveguide structure is designed to perform multiple functions simultaneously - it supports beamforming, transmit diversity, and MIMO configurations within a single component. The waveguide can operate in different modes (TE, TM, hybrid) and support multiple polarizations, making it a universal antenna solution that replaces multiple specialized antennas.
2Productivity
If wireless communication is used to transmit large amounts of data through air-interface, then data transfer capability is improved, but privacy is compromised due to detectability by other radio devices
Solution Approach 1:
The patent introduces a dielectric waveguide as an intermediary medium for data transmission. Instead of transmitting data directly through the air interface where it can be intercepted, the waveguide acts as a physical intermediary that confines and guides the electromagnetic energy, enabling high-speed data transfer while preventing unauthorized detection and maintaining privacy.
3Adaptability or versatility
If device functionalities are expanded to include radar sensors for gesture detection, then sensing capability is improved, but difficulty to fit additional antennas within device increases
Solution Approach 1:
The patent merges communication and sensing functions into a single waveguide structure. The same waveguide that enables high-speed data transfer also functions as a radar sensor for gesture detection and object ranging. By combining these functions, the invention eliminates the need for separate antenna elements, thereby reducing device size while improving versatility.
Solution Approach 2:
The waveguide is designed as a multi-functional component that simultaneously supports wireless communication (data transfer) and radar sensing (gesture detection, object ranging). This universal structure can operate in different modes and frequencies, providing both communication and sensing capabilities within a single integrated system.
