Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed port allocation is used in conventional vectorial network analyzers, then device structure is simple and reliable, but user flexibility deteriorates and complex wiring is required
Solution Approach 1:
The patent implements dynamic port allocation where the control device can assign different measurement channels to different ports based on user requirements. This dynamic assignment mechanism allows the device to adapt to various measuring tasks without requiring complex retrospective calculations, thereby improving user flexibility while maintaining manageable device complexity through software-based control.
2Ease of operation
If fixed port allocation is used, then device structure is simple, but operational complexity increases due to complex wiring requirements
Solution Approach 1:
The control device dynamically assigns measurement channels to ports based on the specific measuring task, eliminating the need for complex wiring configurations. The system adapts its internal channel-port mapping to match user requirements, thereby simplifying operation while managing allocation flexibility through software control rather than physical reconfiguration.
3Adaptability or versatility
If dynamic channel allocation is implemented, then user flexibility is improved, but device complexity increases
Solution Approach 1:
The patent replaces potential mechanical or physical reconfiguration mechanisms with a software-based control system. The control device manages dynamic port-channel assignments through logical routing and software control, eliminating the need for complex mechanical switches or physical reconfiguration hardware, thereby improving flexibility while keeping the actual device structure relatively simple.
4Ease of operation
If display devices are allocated to each port, then ease of operation is improved through clear information display, but manufacturing costs increase
Solution Approach 1:
The patent combines multiple display devices into a single integrated display unit that presents information for all ports and measurement channels in a unified interface. This consolidation reduces the number of individual display components required, lowering manufacturing costs while maintaining ease of operation through centralized, comprehensive information display that shows port assignments, calibration status, and measurement data.

AI summary
A measuring device including a control device, at least two ports, at least two measurement channels and at least two display devices. The control device assigns ports to the measurement channels and connects the measurement channels to these ports internally, at least logically. In this context, one display device is assigned to every port. The display devices allocated to the ports display information, which relates to the present assignment and/or utilization of the respective ports.
