Vacuum Insulating Vessel Wall Structure for Break Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulating vessels made of brittle materials like glass or ceramic are prone to breakage and require excessive material for reinforcement, limiting their stability and vacuum insulation performance.
Innovation Solution
The design features areas of greater wall thickness distributed along the circumference, alternating with thinner sections, providing increased stability without overall material increase, allowing for enhanced vacuum insulation and improved handling and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the outer wall is made uniformly thicker to improve stability, then the breaking resistance increases, but the material consumption increases enormously
Solution Approach 1:
The patent applies local quality by varying the wall thickness of the outer wall according to the specific structural needs of different regions. The outer wall has maximum thickness at the equator, intermediate thickness at the poles, and minimum thickness at the top and bottom openings, where material is removed to form reinforcing elements. This localized thickness variation provides breaking resistance where needed while minimizing overall material consumption.
Solution Approach 2:
The patent segments the outer wall into regions of different thicknesses and introduces separate reinforcing elements (such as rings or ribs) at critical locations. This segmentation allows the structure to achieve high breaking resistance through strategically placed thick sections and reinforcements rather than uniform thickness throughout, reducing total material usage.
2Quantity of substance
If the outer wall is made uniformly thinner to reduce material consumption, then the material usage decreases, but the stability and breaking resistance deteriorate
Solution Approach 1:
The patent applies local quality by varying the wall thickness of the outer wall according to the specific structural needs of different regions. The outer wall has maximum thickness at the equator, intermediate thickness at the poles, and minimum thickness at the top and bottom openings, where material is removed to form reinforcing elements. This localized thickness variation provides breaking resistance where needed while minimizing overall material consumption.
Solution Approach 2:
The patent creates a composite structure by combining the outer wall with separate reinforcing elements (rings, ribs, or other strengthening components) made of the same or different materials. This composite approach allows thin-walled sections to be strengthened without increasing the base wall thickness, achieving high breaking resistance with low overall material consumption.
3Strength
If the wall thickness is increased overall to improve stability, then the breaking resistance increases, but the vacuum insulation performance deteriorates
Solution Approach 1:
The patent applies local quality by varying the wall thickness of the outer wall according to the specific structural needs of different regions. The outer wall has maximum thickness at the equator, intermediate thickness at the poles, and minimum thickness at the top and bottom openings, where material is removed to form reinforcing elements. This localized thickness variation provides breaking resistance where needed while minimizing overall material consumption.

AI summary
A multi-walled insulating vessel made of glass, ceramic, glass ceramic or the like, the walls (3, 4) of which are connected to one another in such a way that they enclose at least one intermediate space between them which is evacuated to a negative pressure, is designed according to the invention in such a way that the outer wall (4) has areas of greater wall thickness (W) arranged around its circumference, which alternate with areas of lesser wall thickness (w). The areas of greater wall thickness (W) are preferably formed along lines (5) and touch at several points (6).
