Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern measurement devices face varying electrical strength requirements for different applications, and existing devices fail to maintain initial electrical strength over time due to environmental influences, affecting high-frequency and high-impedance measurements.
Innovation Solution
A measurement device with an internal enclosure that protects critical components from environmental factors, maintaining laboratory conditions and providing electromagnetic shielding, watertight, and dust-tight seals to preserve the initial electrical strength, ensuring the components are not exposed to contamination, temperature, or humidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are exposed to environmental conditions (temperature, humidity, dirt), then the device can operate in real-world conditions, but the electrical strength deteriorates over time due to aging and contamination
Solution Approach 1:
The device is divided into two distinct environments: an internal enclosure that maintains controlled laboratory conditions for sensitive components, and an external environment that interfaces with real-world conditions. This segmentation allows the sensitive measurement circuitry to remain isolated from degrading environmental factors while the device remains operable in practical applications.
Solution Approach 2:
The internal enclosure acts as an intermediary barrier between the external environment and the sensitive components. It mediates the interaction by filtering out harmful environmental influences (temperature fluctuations, humidity, dirt) while allowing the device to function in real-world conditions, thus preserving electrical strength over time.
2Measurement precision
If internal lines are made short for high frequency applications, then impedance control is improved, but high impedance measurements suffer from reduced electrical strength due to insufficient distance from mass and signal processing components
Solution Approach 1:
Different spatial regions within the internal enclosure are optimized for different measurement requirements. The enclosure provides a controlled environment that allows short internal lines for impedance-controlled high frequency measurements, while simultaneously providing sufficient isolation and distance for high impedance measurements, thus satisfying both contradictory requirements through localized environmental control.
