Solution Overview

Problem

Conventional blending containers with a smaller diameter at the base and larger diameter at the open end face issues such as uneven blending, slow movement of food products, and increased noise due to the draft causing cavitation and inefficient blade operation, especially with viscous food products like frozen drinks and smoothies.

Innovation Solution

A blending container with a reverse draft design where the perimeter of the closed end is larger than the open end, directing food products back to the centerline, reducing cavitation, and allowing for more efficient blending with less noise and reduced blending time, featuring a separately constructed body and base with a molded material and optional NFC tag for interlocking mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a conventional blending container with larger diameter at open end and smaller diameter at base is used, then the container is easier to manufacture with standard molding techniques, but the food product forms a vortex that exposes blades and reduces blending efficiency

Engineering Contradiction:

Improvecontainer manufacturingVSAvoidblending efficiency

Core Design Contradiction:

Ease of manufactureVSProductivity

Solution Approach 1:

The patent inverts the conventional container geometry by making the base diameter larger than the open end diameter. This reverse draft configuration prevents the formation of a vortex that exposes blades, ensuring continuous contact between blades and food product throughout the blending process, thereby significantly improving blending efficiency and productivity.

Inventive Principle:

Principle #13The other way round (Inversion)

2Device complexity

If a conventional blending container with outward sloping sidewalls is used, then the container structure is simpler, but the food product moves slowly and creates cavitation leading to increased noise

Engineering Contradiction:

Improvecontainer structureVSAvoidcavitation and noise

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the sidewall slope direction by making sidewalls slope inward from base to open end rather than outward. This reverse draft configuration eliminates cavitation by preventing vacuum formation during blending, thereby reducing noise and harmful effects while maintaining structural simplicity.

Inventive Principle:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If a conventional blending container with smaller base perimeter is used, then the container fits standard blender bases, but mechanical devices are needed to push food back into blades increasing device complexity

Engineering Contradiction:

Improveblender base compatibilityVSAvoidmechanical pushing devices

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent inverts the perimeter configuration by making the base perimeter larger than the open end perimeter. This reverse draft geometry allows food product to naturally flow toward the centerline and remain in contact with blades during blending, eliminating the need for mechanical pushing devices and reducing overall system complexity while maintaining compatibility with standard blender bases.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A container comprises a body and a base. The body includes an open end and a closed end. The closed end is attached to the base. The closed end may be welded to the base. Cross-sectional perimeters of the body decreases from the closed end to the open end.
