Modular Glass-Lined Beverage Container With Vacuum Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beverage containers, particularly insulated ones, face issues with durability and material compatibility, as stainless steel can react with acidic beverages, imparting a metallic taste, while glass is fragile and lacks durability.
Innovation Solution
A modular beverage container system comprising a glass vessel within a durable metal shell, featuring a press-fit design with vacuum insulation, allowing for easy disassembly and dishwasher safety, using materials like stainless steel, glass, or ceramics for enhanced durability and taste preservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stainless steel is used for the beverage container, then durability and heat transfer limitation are improved, but material compatibility with acidic beverages deteriorates (metallic taste)
Solution Approach 1:
The beverage container is divided into two separate components: an inner vessel made of glass (contacting the beverage) and an outer shell made of stainless steel (providing durability and insulation). This segmentation allows each material to perform its optimal function without the harmful interactions that would occur if they were combined into a single material.
Solution Approach 2:
The glass vessel acts as an intermediary barrier between the acidic beverage and the stainless steel shell. This intermediate layer prevents direct contact between the beverage and the metal, eliminating the metallic taste while preserving the durability and thermal insulation properties of the stainless steel outer shell.
2Object-generated harmful factors
If glass is used for the beverage container, then material compatibility with acidic beverages is improved, but durability deteriorates (fragility)
Solution Approach 1:
The container system is segmented into an inner glass vessel and an outer protective shell. The glass vessel maintains direct contact with the beverage, ensuring chemical compatibility, while the outer stainless steel shell provides mechanical protection against impact and damage, compensating for glass's inherent fragility.
Solution Approach 2:
The system employs a composite structure combining glass and stainless steel materials. The glass inner vessel provides chemical inertness and taste purity, while the stainless steel outer shell provides structural strength and durability. This composite approach leverages the complementary properties of both materials to overcome their individual limitations.
3Ease of operation
If a modular design with press-fit coupling is used, then ease of disassembly and cleaning is improved, but device complexity increases
Solution Approach 1:
The coupling mechanism transitions from a permanent fixed connection to a dynamic reversible press-fit connection. The elastomeric material allows the components to be easily assembled and disassembled by applying radial force, enabling simple cleaning and maintenance while maintaining a relatively simple overall structure without complex fastening mechanisms.
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 modular design provides a durable and safe drinking experience by protecting the glass vessel with a metal shell, maintaining temperature through vacuum insulation, and allowing for easy cleaning and maintenance.
Implementation Method 1
The shell may include an inner wall, an outer wall, an upper rim, and a sealed volume between the inner wall and the outer wall. The sealed volume may be at a vacuum pressure.

AI summary
A beverage container system may include a vessel having an interior volume for containing a beverage and shell having an interior volume for removably coupling vessel therein. The shell may include an inner wall, an outer sidewall, and a sealed volume between the inner wall and the outer wall. The sealed volume may be at a vacuum pressure. The vessel may be constructed from glass while the shell may be constructed from a durable material such as stainless steel.
