Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an antenna is integrated with the projector housing, then the device complexity is reduced and space is saved, but the antenna performance may be degraded due to interference from optical components
Solution Approach 1:
The antenna is segmented into multiple elements arranged in a specific configuration within the projector housing. This segmentation allows each element to be positioned to minimize interference from optical components while maintaining overall antenna functionality and reducing device complexity through integrated design
Solution Approach 2:
A dielectric material is introduced as an intermediary between the antenna elements and the optical components. This dielectric layer acts as a mediator that reduces electromagnetic interference from the optical components while allowing the antenna to maintain its compact integrated form factor
2Power
If nonmetallic optical components are used as antenna substrate, then the electric field generation is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The dielectric constant and thickness of the optical components are carefully selected and optimized to enhance electric field generation. By changing these parameters, the system achieves improved power efficiency and electric field strength while maintaining manufacturability through standard optical component specifications
3Adaptability or versatility
If multiple antennas are integrated to support different frequency bands, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The antenna system is designed with multiple elements that can operate across different frequency bands, providing universal functionality. This multi-functional design allows a single integrated antenna structure to support multiple wireless communication standards and frequency ranges without requiring separate antenna systems for each band
