Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional grounding methods are used to connect contact points to reference potential, then the connection can be established, but reliable monitoring and verification of the grounding status is difficult and safety cannot be ensured
Solution Approach 1:
A conductive fluid is introduced as an intermediary medium between the contact points and reference potential. The fluid flows through a fluid line that contacts each contact point in sequence, providing both the grounding connection and a means to monitor the grounding status by detecting the fluid's electrical conductivity at different positions along the flow path
Solution Approach 2:
The patent uses a hydraulic system with conductive fluid flowing through tubes to establish electrical connections. The fluid circulation system allows continuous monitoring of grounding status by measuring conductivity at various points in the fluid line, enabling reliable detection without complex electrical monitoring circuits
2Reliability
If conductive fluid is used to connect contact points to reference potential, then reliable connection and monitoring is achieved, but the system complexity increases due to additional components like injection devices and measuring sections
Solution Approach 1:
The conductive fluid serves multiple functions simultaneously: it acts as the grounding medium to connect contact points to reference potential, serves as the monitoring medium through conductivity measurements, and provides a continuous circulation system that can detect and indicate grounding status changes. This multi-functionality reduces the need for separate dedicated grounding and monitoring systems
3Measurement precision
If the fluid line is annular and contact points are connected in series, then all contact points can be monitored sequentially, but the time required to wet and monitor all contact points increases
Solution Approach 1:
The annular fluid line creates a continuous circulation system where the conductive fluid constantly flows through all contact points in sequence. This continuous action allows the system to monitor grounding status at all contact points simultaneously over time, with the fluid continuously refreshing and re-establishing connections, eliminating the need for repeated manual checking
Solution Approach 2:
The system establishes preliminary grounding connections through the circulating fluid before formal monitoring begins. The fluid continuously pre-wets and maintains conductive paths to all contact points, ensuring that monitoring measurements can be taken immediately without delay for connection establishment
