Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Datacenter cooling systems face challenges in efficiently managing varying cooling requirements due to changing computing loads, particularly in high heat density areas like those around GPUs, CPUs, and switches, where traditional sensors for leak detection and humidity are not omnipresent and fail to detect leaks effectively unless positioned correctly.
Innovation Solution
An intelligent leak sensor system using a sensor string with flow controllers that enable electrical coupling between sections, allowing for detection of leaks across fluid lines without the need for separate sensors at each location, and can be mechanically and electrically coupled to flow controllers to maintain connectivity and detect leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sensors are positioned at specific locations for leak detection, then the system structure is simple, but the sensors fail to detect leaks effectively unless positioned correctly
Solution Approach 1:
The patent replaces traditional mechanical/optical leak detection sensors with an electrical field-based detection system. A sensor string with conductive elements creates an electrical field that spans across fluid lines, detecting leaks through electrical conductivity changes rather than mechanical positioning. This substitution eliminates the need for precise sensor placement while maintaining high detection reliability.
Solution Approach 2:
The patent transitions from point-based sensor detection (zero-dimensional) to a continuous electrical field detection approach (one-dimensional along the fluid line). The sensor string extends along the fluid line with conductive elements spaced at intervals, creating a dimensional advantage that allows leak detection at any position along the line rather than requiring precise point placement.
2Reliability
If separate sensors are installed at each location for comprehensive leak detection, then leak detection coverage is complete, but the device complexity and cost increase
Solution Approach 1:
The patent merges multiple discrete sensor functions into a single integrated sensor string. The sensor string contains multiple conductive elements spaced along its length, all working together as one continuous detection system. This consolidation provides comprehensive leak detection coverage along the entire fluid line while reducing the number of separate sensor units needed.
Solution Approach 2:
The sensor string serves multiple functions simultaneously: it acts as a structural support element, an electrical connection medium, and a leak detection sensor. The conductive elements serve both as electrical connectors for power/communication and as the active sensing elements for leak detection, eliminating the need for separate sensing components at each location.
3Quantity of substance
If flow controllers are mechanically coupled to enable fluid flow, then fluid circulation is enabled, but electrical connectivity between sections is lost
Solution Approach 1:
The flow controller design merges mechanical fluid coupling with electrical signal coupling into a single integrated interface. The same physical connection that enables fluid flow between sections also establishes electrical connectivity for power and communication signals. This dual-function coupling ensures both fluid circulation and electrical signal continuity without requiring separate connection mechanisms.
Solution Approach 2:
The flow controller interface serves multiple functions simultaneously: it acts as a mechanical valve for fluid flow control, a structural support for the sensor string, and an electrical connector for power and data signals. This multi-functionality resolves the contradiction by making the single connection point responsible for both fluid and electrical connectivity.
