Vacuum-Insulated Bottle Window Structure to Reduce Sweating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insulated drinking bottles are not transparent, making it difficult for users to determine the liquid level inside, and transparent panels often cause sweating issues.
Innovation Solution
A double-walled vacuum jacketed bottle design with an inner and outer tubular body, featuring a transparent panel and an air cavity between them, sealed with a watertight connection to reduce sweating and maintain insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a transparent panel is added to an insulated bottle, then visibility of liquid level is improved, but sweating on the container body worsens
Solution Approach 1:
The patent implements a double-walled vacuum jacket structure where an inner tubular body and an outer tubular body are nested concentrically. The inner body contains the liquid while the outer body provides structural support. This nested configuration creates a vacuum space between the walls that acts as a thermal barrier, preventing condensation (sweating) on the exterior surface while allowing a transparent panel to be integrated into the outer wall for liquid level visibility.
Solution Approach 2:
The vacuum space between the inner and outer tubular bodies serves as an intermediary thermal barrier. This vacuum layer mediates between the liquid inside the bottle and the external environment, blocking heat transfer that would otherwise cause condensation on the outer surface. The transparent panel is integrated into this intermediary structure, allowing optical penetration while maintaining the thermal barrier function.
2Temperature
If insulated material is used to maintain temperature, then temperature maintenance is improved, but transparency of the bottle worsens
Solution Approach 1:
The bottle is segmented into distinct functional layers: an inner tubular body for liquid containment, a vacuum insulation layer for thermal protection, and an outer tubular body with an integrated transparent panel for visibility. This segmentation allows each layer to optimize its specific function while working together as a unified system, resolving the contradiction between insulation and transparency.
Solution Approach 2:
The patent employs a composite structure combining multiple materials and principles: the inner and outer bodies are made of materials suitable for their respective functions, the vacuum space provides thermal insulation without material intervention, and the transparent panel integrates optical clarity with structural integrity. This composite approach allows simultaneous achievement of temperature maintenance and visual access to liquid level.
3Loss of information
If a single-walled transparent bottle is used, then transparency is improved, but insulation capability worsens
Solution Approach 1:
Rather than using a single transparent wall, the patent nests an inner transparent body within an outer transparent body, with a vacuum space between them. This nested configuration maintains transparency by using transparent materials for both walls and the panel, while the vacuum space provides the necessary insulation capability that a single wall cannot achieve.

Function Achieved in This Case
The design allows users to see the liquid level while maintaining insulation, reducing sweating, and enhancing the bottle's durability and aesthetic appeal.
Implementation Method 1
A double-walled vacuum jacketed bottle design with an inner and outer tubular body
Implementation Method 2
an air cavity between the inner transparent panel and outer transparent panel also decreases the amount of sweating on the exterior of the container

AI summary
A bottle with a transparent window having a tubular body, a window opening along the tubular body, and a transparent panel covering the window opening. The tubular body has an outer tubular body, an outer tubular body lower end, and an outer tubular body window opening. The tubular body has an inner tubular body window opening and is positioned inside the outer tubular body that such that the inner tubular body window opening is aligned with the outer tubular body window opening. The tubular body has an upper watertight seal defined by the outer tubular body upper end being attached to the inner tubular body upper end. The tubular body also has a seal defined by an inner tubular body portion proximate to the inner window opening being attached and sealed to an outer tubular body portion proximate to the outer window opening.
