Variable-Width Whisk Frames for Better Mixing Turbulence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food preparation whisks with rectangular frames lack efficiency in mixing food due to uniform width and orthogonal arrangement, leading to suboptimal turbulence and aeration.
Innovation Solution
The whisk design features rectangular frames with inflection points creating distinct widths, asymmetrical shapes, and inclined edges, allowing for enhanced mixing by creating a cavity through centrifugal force and improved turbulence when rotating, with a motor-driven rotation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rectangular frames with uniform width are used, then the structure is simple and easy to manufacture, but the mixing efficiency is insufficient due to lack of turbulence and aeration
Solution Approach 1:
The frame structure transitions from uniform width to variable width with inflection points, creating local variations in geometry. These local quality changes generate turbulence and aeration zones specifically where needed during rotation, improving mixing efficiency without requiring complete structural redesign
Solution Approach 2:
The frame design introduces asymmetry through inflection points that create distinct width variations. When rotated, these asymmetric features generate non-uniform flow patterns, centrifugal forces, and turbulence that significantly enhance mixing performance compared to symmetric uniform frames
2Productivity
If orthogonal arrangement of frames is used, then the construction is straightforward, but the turbulence generation is suboptimal for effective aeration
Solution Approach 1:
The orthogonal arrangement is maintained for construction simplicity, but local quality is enhanced by adding inflection points to the frames. These inflection points create specific zones that generate turbulence and aeration during rotation, improving aeration performance while preserving the straightforward orthogonal construction
3Productivity
If frames with inflection points and distinct widths are used, then turbulence and aeration are enhanced, but the manufacturing complexity increases
Solution Approach 1:
Rather than completely redesigning the frame geometry, the invention applies local quality changes through inflection points on existing rectangular frames. This approach generates the required turbulence during rotation while keeping the overall manufacturing process similar to standard frame fabrication
Solution Approach 2:
The frame geometry parameters are modified by introducing inflection points that create distinct width zones. These parameter changes optimize turbulence generation during rotation while maintaining compatibility with conventional manufacturing methods for rectangular frames
