Fireproof Rack with Sliding Frame and Liquid Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fireproof racks for computer servers are expensive and have structural limitations, with thermal insulation walls being costly and losing fireproofing effectiveness when damaged.
Innovation Solution
A fireproof rack design featuring a major frame, a moveable frame, a fireproof chamber, and a fireproof liquid, where the moveable frame slides to position the object within the chamber for soaking in the liquid, utilizing a simple and cost-effective standard cabinet structure with a temperature sensing and active unit for automatic mode switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specially designed rack body filled with solid firestop material is used, then fireproofing function is improved, but cost increases
Solution Approach 1:
The patent changes the physical state of the fireproofing medium from solid firestop material to liquid fireproofing composition, and changes the rack structure from specially designed to standard cabinet. This parameter change maintains fireproofing effectiveness while dramatically reducing manufacturing cost and simplifying the design.
Solution Approach 2:
The patent employs a standard cabinet structure instead of a specially designed rack body, using inexpensive, readily available components. The fireproofing liquid is contained in a simple reservoir that can be refilled or replaced, rather than requiring expensive specialized materials permanently integrated into the structure.
2Reliability
If thermal insulation walls are used, then fireproofing function is improved, but cost increases
Solution Approach 1:
The patent uses a liquid-based fireproofing system where a pump delivers fireproofing liquid through hoses to the server equipment. This hydraulic approach replaces the need for thermal insulation walls, using fluid dynamics to achieve fire protection through direct application of the fireproofing composition to the protected surfaces.
3Reliability
If thermal insulation walls are used, then fireproofing function is improved, but structural strength requirements increase
Solution Approach 1:
The patent extracts the fireproofing function from the structural walls and enclosure, separating it into an independent liquid delivery system. The standard cabinet structure is freed from the requirement of providing thermal insulation, allowing it to be made from lighter, lower-strength materials while the fireproofing liquid provides the protective function through direct application to equipment surfaces.
4Ease of manufacture
If a standard cabinet structure is used, then manufacturing cost is reduced, but fireproofing effectiveness may decrease
Solution Approach 1:
The system includes a pump and reservoir that proactively deliver fireproofing liquid to the server equipment before a fire event occurs. The liquid is pumped through hoses and applied to surfaces in advance, ensuring immediate fireproofing coverage when needed, rather than relying on passive insulation materials that may be compromised by damage.
Solution Approach 2:
The patent introduces a liquid fireproofing composition as an intermediary substance between the standard cabinet structure and the server equipment. This liquid mediator provides the fireproofing function, allowing the cabinet itself to remain a simple, inexpensive structure without requiring specialized fire-resistant materials or complex insulation systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The fireproof rack effectively protects computer servers by immersing them in a fireproof liquid, enhancing fireproofing functionality while maintaining a low-cost and simple structure, with improved protection and reduced structural strength requirements.
Implementation Method 1
the computer server is soaked in the fireproof liquid

AI summary
A fireproof rack for protecting an object is provided. The fireproof rack includes a major frame, a moveable frame, a fireproof chamber and a fireproof liquid. The moveable frame is slidably connected to the major frame, and the moveable frame slides between a first position and a second position relative to the major frame, and the object is disposed in the moveable frame, and the moveable frame and the object are in the first position under an operation mode. Under a fireproof mode, the moveable frame and the object slide to the second position, and are received in the fireproof chamber. The fireproof liquid is located in the fireproof chamber. When the moveable frame and the object are in the second position, the object is soaked in the fireproof liquid.
