Spring-Loaded Locking Fixture for Vacuum Lifting Servers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum hoists struggle to form airtight seals on servers with seams and embossing, leading to potential damage and dropping during lifting, and deformation of server surfaces.
Innovation Solution
A removable fixture with a cover assembly and wings, featuring alignment and spring-loaded locking mechanisms, ensures linear translation and secure attachment to the server, facilitating safe lifting and moving using vacuum hoists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vacuum hoist is used to lift and move a server, then the operator is protected from injury and server damage, but the vacuum heads may not fully attach due to seams and embossing on the server surface
Solution Approach 1:
A removable cover assembly is introduced as an intermediary between the vacuum hoist and the server. The cover assembly has a smooth planar top surface that enables reliable vacuum sealing, while the server's original surface features (seams and embossing) are excluded from the vacuum interface. The cover mechanically couples to the server through alignment features and locking mechanisms, serving as a mediator that resolves the incompatibility between the vacuum hoist and the server surface.
2Force
If vacuum heads are engaged directly with the server surface, then lifting can be performed, but surface deformation may occur during lifting which could damage the server
Solution Approach 1:
The cover assembly serves as a protective intermediary that distributes the vacuum lifting force across its own structure rather than concentrating it on the server surface. The rigid cover prevents direct contact between the vacuum heads and the server, eliminating the harmful surface deformation while still enabling the necessary lifting force to be applied.
3Reliability
If a removable cover assembly is introduced to enable vacuum lifting, then vacuum sealing is improved, but the device complexity increases
Solution Approach 1:
The lifting system is segmented into distinct functional components: the removable cover assembly, the alignment features, the locking mechanism, and the vacuum hoist. This segmentation allows each component to be optimized for its specific function while maintaining overall system reliability. The cover assembly can be independently manufactured and tested, simplifying the development process despite the increased overall system complexity.

AI summary
A system may include a first alignment feature, a spring-loaded locking feature mechanically coupled to the first alignment feature, the spring-loaded locking feature having a recess formed therein, a second alignment feature configured to mechanically engage with the first alignment feature in order to, when the first alignment feature is mechanically engaged with the second alignment feature, constrain translation of the first alignment feature to the second alignment feature to a linear translation, and a plunger assembly mechanically coupled to the second alignment feature via a compressive spring that mechanically biases the plunger towards the second alignment feature, the plunger assembly comprising a plunger and a tongue extending from the plunger.
