Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If measurement devices are installed in a vehicle for mobile measurements, then measurement flexibility in large and crowded areas is improved, but the difficulty of moving measurement devices from one vehicle to another increases
Solution Approach 1:
The carrier rack is designed with universal mounting capabilities that allow it to be installed in multiple types of vehicles and locations. The stand includes multiple mounting interfaces and adjustable components that enable the same rack structure to be securely installed in different vehicle types (cars, vans, trucks) and even in fixed locations like offices or laboratories, eliminating the need for device-specific mounting solutions for each vehicle type.
Solution Approach 2:
The carrier rack is divided into modular components including a stand, device carrier beams, and test device fixtures. This segmentation allows the rack to be disassembled and reassembled easily when moving between vehicles. The modular design enables quick configuration changes and simplifies transportation, as components can be selectively assembled based on the specific measurement requirements of each vehicle.
2Measurement precision
If multiple test devices are positioned at a specific location (e.g., window opening) for optimal RF reception, then measurement quality is improved, but the complexity of arranging and repositioning devices increases
Solution Approach 1:
The device carrier beams are designed to be movable along the stand structure, and the test device fixtures can be adjusted to different positions on the beams. This dynamic positioning capability allows test devices to be quickly reconfigured from one optimal measurement location to another without complex manual arrangement. The movable mechanisms enable smooth transitions between positions while maintaining secure device holding at each location.
Solution Approach 2:
The device carrier beams act as intermediary elements between the fixed stand structure and the movable test devices. These beams provide guided movement paths and positioning mechanisms that simplify the repositioning process. By introducing this intermediate layer, the system enables easy adjustment of device positions along predefined trajectories without requiring direct manual manipulation of each device relative to the stand structure.
