Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If evaluation electronics are integrated on the carrier plate with the generator and antenna, then device functionality is complete, but device complexity and space requirements increase significantly
Solution Approach 1:
The radar sensor system is divided into two separate modules: a compact carrier plate containing the generator and antenna for microwave transmission, and a separate printed circuit board housing the evaluation electronics. This segmentation allows each module to be optimized independently and simplifies the constructional effort on the carrier plate while maintaining complete device functionality.
Solution Approach 2:
The L-shaped angled component introduces a three-dimensional spatial arrangement, positioning the antenna perpendicular to the carrier plate surface. This dimensional change enables efficient microwave radiation while separating the evaluation electronics to another plane (printed circuit board), reducing the complexity on the carrier plate.
2Reliability
If the antenna is positioned perpendicular to the carrier plate for efficient microwave radiation, then radiation characteristic is improved, but space requirements and manufacturing complexity increase
Solution Approach 1:
The L-shaped angled component serves as an intermediary structure that connects the carrier plate to the antenna at a perpendicular angle. This mediator enables the antenna to be positioned optimally for microwave radiation while keeping the antenna structurally supported and aligned, balancing manufacturing ease with radiation performance.
3Area of stationary object
If the carrier plate size is minimized to fit process connections, then space efficiency is improved, but the generator and antenna integration becomes more difficult
Solution Approach 1:
By separating the evaluation electronics from the carrier plate, the carrier plate dimensions can be minimized to fit within process connections while still accommodating the generator and antenna. The segmentation allows the small carrier plate to focus only on microwave generation and transmission functions.
Solution Approach 2:
The L-shaped angled component utilizes vertical space perpendicular to the carrier plate, allowing the antenna to extend outward without increasing the carrier plate's footprint area. This dimensional approach enables compact integration within process connection dimensions.
