Solution Overview

Problem

Conventional whisks for kitchen appliances suffer from deformation and difficulty in cleaning due to their design, which affects the efficiency and reliability of food processing.

Innovation Solution

A whisk design featuring a rod connected to a drive, with a plurality of bows connected by a joining element spaced apart from the rod, enhancing stiffness and facilitating easy cleaning, while allowing uniform distribution and improved contact with the bowl surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional whisk design with interlaced wire loops is used, then the whisk can be manufactured simply, but the whisk deforms during operation and is difficult to clean

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidstructural stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The whisk is divided into separate functional components: individual bows that are pre-formed and then assembled to the rod via connector portions. This segmentation allows each bow to be manufactured independently with precise geometry, preventing deformation during operation while maintaining manufacturing simplicity through modular assembly.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If conventional whisk design with interlaced wire loops is used, then the whisk structure is compact, but the whisk is difficult to clean

Engineering Contradiction:
Improvestructural compactnessVSAvoidcleaning ease
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The joining element is extracted as a separate, easily accessible component that connects the bows to the rod. This extraction allows the joining element to be quickly removed for cleaning purposes, eliminating the cleaning difficulties associated with conventional interlaced wire loop designs while maintaining a compact overall structure during operation.

Inventive Principle:
Principle #2Taking out (Extraction)

3Stability of the object's composition

If bows are uniformly distributed about the longitudinal axis, then the whisk achieves rotational symmetry and balanced operation, but the production complexity increases

Engineering Contradiction:
Improverotational balanceVSAvoidproduction complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The number of bows is standardized to specific values (12, 16, or 18) that provide optimal rotational symmetry and balance. This parameter change allows for simplified manufacturing through repetitive modular assembly, as each bow is identical and can be attached at regular intervals, achieving rotational balance without excessive production complexity.

Inventive Principle:
Principle #35Parameter changes
