Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional radiating system is used to achieve wideband radio-frequency performance, then the radio-electric performance is improved, but the device size and complexity increase
Solution Approach 1:
The radiating system is segmented into a ground plane layer and multiple booster bars positioned at different heights above it. This segmentation allows each component to be optimized independently while working together to achieve wideband performance without requiring a complex monolithic structure.
Solution Approach 2:
The patent introduces a vertical dimension by positioning booster bars at different heights above the ground plane layer. This three-dimensional arrangement enables wideband radio-frequency performance without increasing the horizontal footprint, thus avoiding device complexity while maintaining performance.
2Reliability
If a traditional radiating system is used to achieve wideband radio-frequency performance, then the radio-electric performance is improved, but the space occupied increases
Solution Approach 1:
By utilizing the vertical dimension with booster bars positioned at different heights above the ground plane, the system achieves wideband performance without expanding the horizontal area. This vertical stacking approach minimizes the overall volume occupied by the radiating system.
Solution Approach 2:
The booster bars are nested vertically above the ground plane layer in a compact arrangement. This nesting approach allows multiple radiating elements to occupy minimal space while maintaining their individual functions for wideband performance.
3Reliability
If a radiating system is customized for each device model to achieve good radio-electric performance, then the performance is improved, but the manufacturing cost and time increase
Solution Approach 1:
The radiating system with ground plane layer and booster bars is designed as a universal configuration that can be integrated into different device models without customization. The modular structure maintains good radio-electric performance across various applications, reducing manufacturing complexity and cost.
Solution Approach 2:
The radiating system is pre-configured with optimally positioned booster bars and ground plane layer during manufacturing. This preliminary configuration ensures good radio-electric performance is achieved without requiring model-specific customization, thereby reducing production time and cost.
4Length of moving object
If the radiating system is made slim and flat to reduce device size, then the device thickness is reduced, but the radio-electric performance deteriorates
Solution Approach 1:
The patent achieves a slim profile by utilizing the vertical dimension for booster bar positioning rather than increasing horizontal dimensions. This maintains device thickness while preserving radio-electric performance through the three-dimensional radiation pattern created by vertically stacked elements.
Solution Approach 2:
The radiating system uses a composite structure combining a ground plane layer with dielectric material and conductive booster bars. This composite configuration enables slim form factor while maintaining effective radio-electric performance through the coordinated interaction of different materials and layers.
