Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-frequency measurement devices require additional complex and costly spread spectrum modules, increasing efforts and costs when measuring high-frequency signals.
Innovation Solution
A measurement device with multiple ports and measurement units, where an additional frequency-selective measurement unit can be connected to extend the frequency range efficiently, reducing costs and complexity by integrating the additional unit within the device and using a signal routing unit for signal forwarding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a spread spectrum module is added to extend frequency range, then measurement capability at high frequencies is improved, but device complexity and cost increase
Solution Approach 1:
The additional measurement unit is designed to be frequency-selective and operable in parallel with existing measurement units, allowing a single device to handle multiple frequency ranges. This multi-functional approach enables the measurement device to cover both standard and extended frequency ranges without requiring separate dedicated modules for each frequency band, thereby reducing overall device complexity while maintaining versatility.
2Adaptability or versatility
If a spread spectrum module is added to extend frequency range, then measurement capability at high frequencies is improved, but cost increases
Solution Approach 1:
The additional measurement unit is integrated directly into the measurement device architecture and shares common components such as the housing, power supply, and control systems with the existing measurement units. This merging approach eliminates the need for separate external modules and reduces manufacturing costs by utilizing shared resources across the entire device rather than requiring expensive standalone spread spectrum modules.
3Adaptability or versatility
If multiple measurement units are integrated within the device, then external hardware needs are reduced, but internal device complexity increases
Solution Approach 1:
The measurement device is segmented into multiple independent measurement units, each capable of operating in parallel and handling specific frequency ranges. This segmentation allows each unit to be optimized for its specific function while maintaining modularity, making the overall system more manageable and less complex than a monolithic design would be. Each measurement unit can be independently controlled and calibrated, simplifying the management of internal complexity.
