Removable Planar Fixture for Vacuum-Sealed Server Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum hoists struggle to form an airtight seal on servers with seams and embossing, leading to potential damage and difficulty in lifting and moving information handling system servers safely.
Innovation Solution
A removable fixture with a planar cover and alignment features, along with a spring-loaded locking mechanism, ensures a secure linear translation of the cover relative to the server, allowing vacuum hoists to create a stable seal and lift the server effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a vacuum hoist is used to lift servers, then lifting capability is improved, but sealing reliability deteriorates due to seams and embossing on server surfaces
Solution Approach 1:
A fixture acts as an intermediary between the vacuum hoist and the server. The fixture includes a sealing surface that interfaces with the vacuum hoist's vacuum head, while alignment features interface with the server. This mediator resolves the sealing problem by providing a dedicated sealing interface that isn't compromised by server surface features like seams and embossing.
Solution Approach 2:
The lifting system is segmented into three distinct components: the vacuum hoist, the fixture, and the server. The fixture is further segmented into a sealing surface portion and an alignment feature portion. This segmentation allows each component to be optimized for its specific function - the sealing surface for vacuum sealing and the alignment features for mechanical engagement with the server.
2Ease of operation
If vacuum heads are engaged directly with server surface, then lifting operation is simplified, but damage risk increases due to incomplete sealing and surface deformation
Solution Approach 1:
The fixture serves as a protective intermediary that absorbs the complexity of the sealing and alignment functions. The vacuum hoist operator simply needs to engage the vacuum head with the fixture's sealing surface, without needing to concern themselves with server surface irregularities. This maintains ease of operation while the fixture's design inherently protects against damage through proper force distribution and alignment.
3Manufacturing precision
If alignment features are added to the fixture, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The fixture applies local quality by concentrating alignment functionality in specific localized features (such as alignment pins, slots, or keyed interfaces) rather than distributing complexity throughout the entire structure. The majority of the fixture remains simple, with only specific regions containing alignment features, thereby minimizing overall complexity while achieving precise positioning where needed.
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 fixture facilitates safe and damage-free lifting and moving of servers by maintaining a stable vacuum seal, reducing the risk of deformation and drop during handling.
Implementation Method 1
A vacuum hoist may comprise a system, device, or apparatus that employs a mechanical vacuum wherein vacuum heads are engaged with a surface of the server to create a mechanical force that offsets and/or overcomes the force of gravity upon the server to lift and move the server.

AI summary
A removable fixture may include a cover assembly, comprising a cover having a top surface which is generally planar and substantially void of any features formed thereon, one or more first alignment features mechanically coupled to a side of the cover, and a wing. The wing may have one or more keyholes configured to mechanically engage with one or more corresponding coupling structures on a physical object and one or more second alignment features configured to mechanically engage with the one or more first alignment features in order to, when the one or more first alignment features are mechanically engaged with the one or more second alignment features, constrain translation of the cover relative to the physical object to a linear translation.
