Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems for computing devices face challenges in preventing fluid overflow during the ejection of liquid cooled computing devices from a rack manifold, leading to potential damage from residual fluid runoff.
Innovation Solution
A fluid reservoir device is introduced, which is operable to expand and contract in conjunction with the disconnection and connection of the computing device from the rack manifold. This device provides a flexible volume within the chassis reservoir to capture residual fluid runoff, preventing spillage during the ejection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the computing device is ejected from the rack manifold, then the computing device can be removed or replaced, but residual fluid runoff causes overflow and potential damage
Solution Approach 1:
A reservoir is provided in the rack manifold that captures residual fluid runoff before it can overflow and damage electronic equipment. The reservoir acts as a pre-prepared containment structure that cushions against the harmful effect of fluid overflow during device ejection.
Solution Approach 2:
The reservoir serves as an intermediary component between the fluid cooling system and the electronic equipment. It intercepts and contains residual fluid runoff, preventing direct contact between the fluid and sensitive electronic components during the ejection process.
2Reliability
If the fluid reservoir device is expanded to capture more fluid, then fluid containment is improved, but the device complexity increases
Solution Approach 1:
The reservoir is designed with a flexible bottom that can dynamically change its shape and volume. As fluid accumulates during device ejection, the flexible bottom deflects downward to accommodate the fluid, providing adaptive containment without requiring complex mechanical expansion mechanisms.
Solution Approach 2:
The reservoir utilizes a flexible membrane or thin-walled structure at its bottom that can deform to accommodate varying fluid volumes. This flexible shell approach provides reliable fluid containment while maintaining structural simplicity, avoiding the need for complex articulated or segmented expansion mechanisms.

AI summary
A fluid reservoir device is provided. A body forms a reservoir operable to receive fluid. The body is operable to transition between a contracted configuration and an expanded configuration such that the body in the expanded configuration expands a volume of the reservoir. A transition component is operable to transition the body between (1) the expanded configuration to the contracted configuration as a computing device fluidly connects with a rack manifold, and (2) the contracted configuration to the expanded configuration as the computing device disconnects from the rack manifold.
