Solution Overview

Problem

Existing blenders often face challenges in efficiently blending ingredients due to the design of the container and blade assembly, which can lead to incomplete mixing and difficulty in introducing or removing ingredients.

Innovation Solution

A liner for a blender is introduced, which fits within the blender cup and includes a design that allows for mechanical coupling with the blade assembly, forming a seal to contain ingredients during blending. The liner's perimeter features, such as a lip with a bead structure, enhance the sealing and retention capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a container has an opening on one end for introducing ingredients and removing blended mixture, then ease of operation is improved, but the container cannot be mechanically coupled with a blade assembly for blending operation

Engineering Contradiction:
Improveease of introducing and removing ingredientsVSAvoidability to be mechanically coupled with blade assembly
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The container is divided into two separate components: the cup body with opening for ingredient introduction, and a separate lid assembly that interfaces with the blade assembly. This segmentation allows the cup to maintain its opening for ease of operation while the lid provides the mechanical coupling capability for blending.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lid assembly is designed to nest over the cup opening, creating a integrated structure that combines the ingredient introduction function of the cup with the blade coupling function of the lid. The blade assembly then nests onto the lid assembly, forming a complete blending system.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If an end of container is dedicated for mounting onto base unit, then reliability of blending operation is improved, but ease of introducing and removing ingredients is worsened

Engineering Contradiction:
Improvereliability of blending operationVSAvoidease of introducing and removing ingredients
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The container system is segmented into the cup (for ingredient access) and lid assembly (for blade mounting). The lid assembly includes the interface for mechanical coupling with the blade assembly, ensuring reliable blending operation while the cup maintains open access for ingredient introduction.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lid assembly serves as an intermediary component between the cup and the blade assembly. It provides the mechanical coupling interface for reliable blade attachment while allowing the cup to maintain its ingredient access function, thus mediating between the two conflicting requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If liner includes lip with bead structure for sealing and retention, then sealing capability is improved, but device complexity increases

Engineering Contradiction:
Improvesealing capabilityVSAvoidcomplexity of liner structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The liner is constructed as a flexible thin-walled structure with an integrated lip and bead feature. The flexibility of the thin film material allows the bead to deform and conform to the cup surface, creating an effective seal without requiring complex rigid sealing mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sealing lip and retention bead features are merged into a single integrated structure formed as part of the liner itself. This combination eliminates the need for separate sealing components, reducing overall device complexity while maintaining sealing capability.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

In some embodiments, a liner for a blender can include a body dimensioned to fit within a cup for the blender. The body can define an inner volume and include an opening with a perimeter configured to engage a perimeter of an opening of the cup, such that when the liner is positioned within the cup, the resulting assembly is capable of being mechanically coupled with a blade assembly to enclose the volume with one or more ingredients therein for blending operation by the blender.
