Solution Overview

Problem

Conventional blenders lack an efficient means to cool food during processing, limiting their ability to prepare cold foods like frosty smoothies effectively in a domestic environment.

Innovation Solution

A jar for a blender that incorporates a detachable cooler element, which can be cooled in a refrigerator or freezer, and is designed to be combined with a tool holder and wall component to form a food reception space where the cooler element helps lower the temperature of food being processed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a conventional blender jar is used without a cooling element, then the device structure remains simple, but the ability to cool food during processing is lost

Engineering Contradiction:
Improvefood temperatureVSAvoidjar structure
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The jar is divided into separate detachable components: a base element, a cooler element, and a wall component. This segmentation allows the cooling function to be added as a separate module that can be easily removed or replaced, minimizing the impact on overall device complexity while enabling temperature control during food processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cooler element is nested within the jar structure, specifically positioned at the bottom of the food reception space. The cooler element fits inside the base element or wall component, creating a compact integrated design where the cooling mechanism is contained within the existing jar geometry without significantly increasing external dimensions or structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a detachable cooler element is added to the jar, then passive cooling capability is enabled, but the number of components and assembly steps increases

Engineering Contradiction:
Improvecooling functionVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base element is designed to serve multiple functions: it forms the structural base of the jar, provides mounting for the blade assembly, and houses the detachable cooler element. This multi-functionality reduces the need for separate dedicated cooling components, thereby adding cooling capability without proportionally increasing the total number of parts.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The cooler element is designed to be pre-cooled in a refrigerator or freezer before use, and then simply inserted into the jar assembly. This preliminary cooling action transfers the cooling function to the component itself rather than requiring an active cooling system during operation, reducing the complexity of the blender while maintaining the cooling function.

Inventive Principle:
Principle #10Preliminary action

3Temperature

If the cooler element delimits the food reception space, then cooling efficiency is improved, but the usable volume of the jar is reduced

Engineering Contradiction:
Improvecooling efficiencyVSAvoidfood reception space
Core Design Contradiction:
TemperatureVSVolume of stationary object

Solution Approach 1:

The cooler element is positioned specifically at the bottom of the food reception space, where it delimits a portion of the volume. This localized cooling approach concentrates the cooling effect in the region where food contacts the cooler element most directly, improving cooling efficiency in the critical zone while minimizing the overall reduction in food reception capacity. The cooler element does not occupy the entire jar volume, preserving adequate space for food processing.

Inventive Principle:
Principle #3Local quality

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 integration of a cooler element into the blender jar provides a passive cooling mechanism, enabling the preparation of cool and cold foods like frosty smoothies in a domestic setting, enhancing convenience and efficiency.

Implementation Method 1

the cooler element (i.e., a surface thereof) at least partially delimits the food reception space... the food may contact the cooler element. The present invention thus facilitates that, if the cooler element has recently been taken out of the cooling environment before assembling and using the jar, the temperature of the food being processed may be lowered due to its contact with the cooler element.

Methodology Applied
Scientific EffectThermal conduction: Conduction (thermal)

Implementation Method 2

The cooler element may preferably contain a latent heat accumulator which can comprise a phase change material.

Methodology Applied
Scientific EffectPhase change: Phase Change

AI summary

Disclosed is a jar 100 for or of a blender 1. The jar comprises a tool holder 10, a wall component 30 and a cooler element 20 which are detachably combinable such that, in a combined state, they define a food reception space R designated to receive food to be processed by the blender 1. Therein the cooler element 20 at least partially delimits the food reception space R. Further disclosed is a (stationary) blender 1 with such jar 100 and a base 200, the base defining an operation position of the jar 100 and comprising an electric motor.
