Getter Sheet Elastic Deformation for Vacuum Package Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional package elements require additional parts and increased production time and costs to secure a getter within a vacuum enclosure, as they often necessitate the use of holders and fasteners to hold the getter in place.
Innovation Solution
A getter sheet is positioned between a base and a cap of the package, with at least one portion in contact with the package, allowing it to deform elastically and secure itself without additional parts or fasteners, thereby simplifying the assembly and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a holder and fasteners are used to secure the getter within the package, then the getter is securely held in place, but the production time and costs increase
Solution Approach 1:
The patent removes the holder component from the package structure, allowing the getter sheet to be positioned and secured directly between the base and cap surfaces. This extraction of the holder eliminates the need for additional fasteners and reduces assembly steps, directly resolving the contradiction between securing reliability and production efficiency
Solution Approach 2:
The getter sheet itself serves as the securing element by being positioned in elastic deformation between the base and cap, using its own material properties to maintain position without requiring external holders or fasteners. This self-service approach eliminates additional components while maintaining securing reliability
2Reliability
If a holder is used to hold particulates of the getter, then the getter is securely positioned, but the number of parts increases
Solution Approach 1:
The patent merges the getter sheet with the positioning function by having it directly contact and deform between the base and cap surfaces. This combines the getter material with the positioning mechanism, eliminating the need for separate holders and reducing the total number of parts while maintaining positioning stability
Solution Approach 2:
The holder is completely removed from the system, and the getter sheet is positioned to perform both its gas-absorbing function and its positioning function simultaneously, reducing component count while maintaining reliability
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
This method effectively secures the getter sheet within the package, reducing production time and costs while maintaining efficient gas absorption capabilities, as the getter sheet is forced into a vaulted form, maximizing exposure to the vacuum space without the need for additional components.
Implementation Method 1
a getter sheet positioned between a base and a cap of the package with at least one portion of the getter sheet in contact with the package to secure the getter sheet within the package in a condition of elastic deformation. When positioned within the package between the base and cap, the condition of elastic deformation may force the getter sheet into a vaulted form.
Implementation Method 2
a getter sheet positioned between a base and a cap of the package... The getter sheet comprises particulates of a getter applied to a sheet of material... means for absorbing gasses within the vacuum enclosure

AI summary
A getter sheet is secured within a package element in a condition of elastic deformation by positioning the getter sheet between a base and a cap of a package with at least one portion of the getter sheet in contact with the package. When positioned within the package, the condition of elastic deformation may force the getter sheet into a vaulted form. Therefore, the getter sheet may be secured within the package without utilizing any additional parts or fasteners. The getter sheet comprises particulates of a getter applied to a sheet of material. The getter sheet may comprise a rectangular shape, an elliptical shape, or an octagonal shape. The getter sheet may be secured within the package when at least one portion of the getter sheet contacts one or more of a side surface of the cap, a bottom surface of the cap, and a top surface of the base.
