Double-Walled Blending Container for Insulation and Noise Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional blending containers are prone to noise during operation, fail to insulate users from hot or cold food substances, are cumbersome and prone to breakage, and have difficulties in molding ergonomic designs with graduations.
Innovation Solution
A double-walled blending container with a plastic carrier and a glass liner, where the carrier circumscribes the liner, providing thermal insulation, reducing noise, and enhancing user safety and comfort, while the plastic carrier reduces weight and susceptibility to scratches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glass container is used for blending, then the container is transparent and chemically inert, but it is heavy and prone to breakage
Solution Approach 1:
The blending container uses a composite structure combining glass liner (for chemical inertness and transparency) with an outer carrier made of durable plastic material (for impact resistance and reduced weight). This composite approach allows the glass liner to provide its beneficial properties while the outer carrier protects against breakage and reduces overall weight through material selection.
Solution Approach 2:
The container is divided into separate components: an inner glass liner and an outer plastic carrier. This segmentation allows each material to be optimized for its specific function - glass for chemical resistance and transparency, plastic for mechanical protection and weight reduction - while working together as a unified container system.
2Temperature
If a single-wall container is used, then the structure is simple, but it transmits heat and makes handling hot or cold foodstuffs unpleasant
Solution Approach 1:
The container employs a nested double-wall structure where the glass liner is positioned inside the outer plastic carrier, creating an insulating air gap between them. This nested configuration provides thermal insulation to protect users from hot or cold surfaces while maintaining a relatively simple overall container design.
Solution Approach 2:
An air gap acts as an intermediary thermal barrier between the inner glass liner containing the foodstuff and the outer carrier that contacts the user's hand. This intermediary layer prevents direct heat transfer, insulating the user from extreme temperatures while adding minimal structural complexity.
3Strength
If a glass container contacts dense materials like sinks or utensils, then it may be durable, but it is prone to external and internal breakage
Solution Approach 1:
The outer plastic carrier serves as a protective cushion that absorbs and distributes impact forces before they reach the inner glass liner. This beforehand cushioning prevents direct contact between the fragile glass and hard surfaces like sinks or countertops, significantly reducing the risk of breakage while maintaining overall container strength.
Solution Approach 2:
The combination of glass liner and plastic outer carrier creates a composite structure where the plastic material provides impact resistance and shock absorption, protecting the glass component from breakage during handling and contact with dense materials.
4Ease of operation
If glass is molded with ergonomic features and graduations, then the container is functional, but the molding process is difficult
Solution Approach 1:
The container features are segmented between two components: the glass liner maintains simplicity for easy manufacturing and cleaning, while the outer plastic carrier incorporates ergonomic handles, measurement graduations, and structural features. This segmentation allows complex ergonomic features to be molded into the plastic without complicating glass manufacturing.
Solution Approach 2:
By distributing features between glass and plastic components, the design leverages the manufacturing advantages of each material - glass can be produced with simple, durable surfaces, while plastic allows for easy integration of ergonomic handles, spouts, and graduated markings through standard molding techniques.

AI summary
A container of a blending system is shown and described. The container may include a carrier formed from a first material, the carrier configured to engage a base of the blending system. The container may also include a liner positioned in the carrier a distance apart from the carrier, wherein the carrier generally circumscribes the liner, where the liner is formed from a second material different from the first material.
