Single-Arm Kneading Tool With Wiper for Easy Dough Cleaning
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
2Ease of operation
If a simple kneading tool design is used, then cleaning ease is improved, but kneading performance may be insufficient
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
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
