Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna system is customized for every particular wireless handheld device model, then the radio-electric performance is optimized, but the device complexity and production costs increase
Solution Approach 1:
The antenna system is divided into multiple independent antenna components, each capable of operating at different frequency bands. These modular components can be selectively assembled to create customized antenna systems for different device models, maintaining optimized radio-electric performance while reducing overall system complexity and production costs through standardization.
Solution Approach 2:
The antenna components are designed with universal characteristics that allow them to function across multiple frequency bands and communication standards. This multi-functionality enables the same antenna components to be used in different device models, reducing customization requirements while maintaining optimized performance through selective assembly.
2Volume of moving object
If the radiating system is made small to occupy less space, then the device space utilization improves, but the bandwidth and radiation efficiency deteriorate
Solution Approach 1:
The antenna system is segmented into multiple compact antenna components, each optimized for specific frequency bands. This segmentation allows each component to maintain adequate electrical dimensions for its designated band while keeping the overall physical footprint small, as not all components are active simultaneously in all devices.
Solution Approach 2:
Each antenna component is designed with local quality optimization, where the dimensions and geometry of each component are specifically tailored to its intended frequency band operation. This allows compact sizing for each component while maintaining the bandwidth and efficiency required for its specific function.
3Adaptability or versatility
If booster elements are used to cover large bandwidths and low-frequency bands, then the frequency coverage improves, but the size and volume of the antenna system increase
Solution Approach 1:
Instead of using large booster elements to cover broad frequency ranges, the system segments the frequency coverage into multiple dedicated antenna components. Each component is optimized for specific frequency bands, allowing compact sizing while achieving comprehensive frequency coverage through selective assembly of appropriate components.
Solution Approach 2:
The patent transitions from attempting to cover all frequency bands within a single two-dimensional antenna structure to using multiple compact three-dimensional antenna components. This dimensional approach allows each component to be optimized for its specific frequency range while maintaining small overall volume through selective assembly.
