Solution Overview

Problem

Existing domestic kitchen appliances for making frozen desserts and non-dessert food products are inefficient and impractical, requiring significant time and effort, and are limited in their functionality.

Innovation Solution

A handle mechanism for a micro-puree machine that allows users to control the speed of food extrusion through a lever-activated electrical circuit, which adjusts the motor output speed based on the angle of rotation, enabling efficient and controlled extrusion of food materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a traditional kitchen appliance with refrigeration mechanism is used, then frozen desserts can be made, but the time and effort required is excessive

Engineering Contradiction:

Improvespeed of frozen dessert preparationVSAvoidtime required for chilling and churning

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The bowl and ingredients are pre-chilled in the freezer before use, so that when the micro-puree machine operates, the refrigeration mechanism is already in place and the ingredients are at the correct temperature. This eliminates the need for prolonged chilling time during the actual processing operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent separates the refrigeration function into a standalone pre-chilling step (freezing the bowl and ingredients beforehand) from the extrusion function. The micro-puree machine itself does not need an integrated refrigeration mechanism, allowing it to operate quickly without the time-consuming churning process of traditional ice cream makers.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If a micro-puree machine with manual lever operation is used, then extrusion speed can be controlled, but the device complexity increases with electrical circuits

Engineering Contradiction:

Improvecontrol over extrusion speedVSAvoidcomplexity of electrical circuit and angle sensing

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces a purely mechanical variable speed control mechanism with an electrical circuit system. The lever's angle of rotation is detected by an electrical circuit (such as a potentiometer or encoder) that converts the mechanical position into an electrical signal, which then controls the motor speed. This provides more precise and responsive control while keeping the overall system manageable.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The electrical circuit acts as an intermediary between the mechanical lever input and the motor output. It translates the user's manual lever movement into proportional motor speed control, providing a smooth transition between mechanical operation and electrical actuation without requiring direct mechanical coupling for variable speed control.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If the lever is coupled directly to the motor, then the structure is simple, but the control precision over extrusion speed is reduced

Engineering Contradiction:

Improveprecision of lever angle measurementVSAvoidcomplexity of electrical coupling system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses an electrical sensing system (such as a potentiometer, encoder, or other angle-sensing circuit) to measure the lever's angle of rotation with high precision. This electrical measurement system provides accurate feedback on lever position without requiring complex mechanical linkages or gear systems, achieving precise control through electrical rather than mechanical means.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If the micro-puree machine is designed for versatile food preparation, then adaptability is improved, but the device complexity increases

Engineering Contradiction:

Improveability to prepare both dessert and non-dessert foodsVSAvoidcomplexity of handling different food types

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The micro-puree machine is designed with a universal bowl and extrusion system that can handle both soft frozen desserts and firmer non-dessert foods. The variable speed control allows the same basic mechanism to adapt to different food consistencies - slower speeds for delicate ice creams and faster speeds for tougher foods - without requiring separate mechanisms for different food types.

Inventive Principle:

Principle #6Universality (Multi-functionality)
