Solution Overview

Problem

Existing kneading tools for dough are cumbersome to clean due to their complex designs with many edges and ridges, which hinders efficient cleaning and maintenance.

Innovation Solution

A kneading device with a kneading tool featuring a central body and a single agitating arm, along with at least one axially and radially extending wiper, designed for easy cleaning and efficient dough kneading, where the wiper's shape and the bowl's geometry work together to enhance kneading forces and dough movement, and the tool can be made from materials like metal, plastic, or glass fiber with non-stick surfaces for improved performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a kneading tool with multiple agitating arms and scoops is used, then kneading performance is improved, but cleaning difficulty increases due to many edges and ridges

Engineering Contradiction:
Improvekneading performanceVSAvoidcleaning ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent removes unnecessary components (multiple agitating arms, scoops, ribs) and retains only the essential wiper element that contacts the dough. This extraction of essential function eliminates edges and ridges while maintaining kneading capability through the wiper's radial and axial design

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The wiper is designed with a curved, ribless surface that follows the rotational motion without creating sharp edges. The smooth curved geometry eliminates ridges that would trap dough, making the tool easy to clean while maintaining effective dough contact

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Ease of operation

If a simple kneading tool design is used, then cleaning ease is improved, but kneading performance may be insufficient

Engineering Contradiction:
Improvecleaning easeVSAvoidkneading performance
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The single wiper element performs multiple functions: it scrapes the bowl wall, folds dough onto itself, and provides the necessary kneading action through its radial extension. This multi-functionality in a simple design maintains kneading performance without requiring multiple separate components

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

Solution Approach 2:

The wiper extends both radially from the central body and axially along the bowl height, creating a two-dimensional surface that contacts dough at multiple points simultaneously. This dimensional extension provides effective kneading coverage without adding complex three-dimensional structures

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
