Solution Overview

Problem

Traditional stand mixers have a thin shell structure that is difficult to clean due to cavities and complex ribbing, which complicates processing and maintenance.

Innovation Solution

A stand mixer with a base comprising integrally formed solid thin plates in an inverted C configuration, processed using semi-fusion hot forging, eliminating cavities and featuring a hinge for easy head lifting and a mixing bowl mounting seat for simplified installation and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If ribs are adopted to increase shell strength, then the shell strength is improved, but the bottom structure becomes complex and difficult to clean

Engineering Contradiction:
Improveshell strengthVSAvoidbottom structure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent removes the cavity and rib structures from the base design, extracting the problematic complex internal structure while maintaining external strength through a solid thin plate configuration with sufficient thickness (12-30mm), thereby simplifying the bottom structure for easy cleaning

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of manufacture

If the shell thickness is reduced to 2-3.5mm, then the manufacturing cost is reduced, but the shell becomes too thin and requires additional ribs for strength

Engineering Contradiction:
Improvemanufacturing costVSAvoidshell strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent changes the thickness parameter to an optimal range of 12-30mm for the solid thin plate base, which is thicker than traditional shells but eliminates the need for additional reinforcing ribs, achieving both cost-effectiveness and structural strength without complex geometry

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a cavity is formed in the bottom of the base, then the structural design flexibility is improved, but the cleaning difficulty increases

Engineering Contradiction:
Improvestructural design flexibilityVSAvoidcleaning ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent extracts and eliminates the cavity structure from the base design, adopting a solid thin plate configuration that provides sufficient structural flexibility through material selection and thickness optimization (12-30mm) while ensuring the bottom surface is completely smooth and cavity-free for easy cleaning

Inventive Principle:
Principle #2Taking out (Extraction)
