Twisted Blender Blade Wings for Wide-Range Volume Blending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional blenders face challenges in efficiently processing varying volumes of working medium, as existing blades are limited to specific container sizes, leading to suboptimal performance when handling volumes between 6 ounces and 48 ounces, particularly with narrow or wide-based containers.
Innovation Solution
A blender blade design featuring multiple angled blade wings and transition sections that allow for adjustable cutting patterns and axial flow control, enabling efficient processing of 6 to 48 ounces of working medium in both narrow and wide-based containers by optimizing the angle of attack and wing flap orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a traditional blender blade is used in a narrow-based container, then the blade can process small volumes of working medium (6-12 ounces), but it cannot effectively process larger volumes (over 32 ounces)
Solution Approach 1:
The blade wing is designed with a twist along its longitudinal length, creating variable angles of attack at different radial positions. This dynamic geometric configuration allows the blade to adapt its cutting pattern to different volumes of working medium, enabling effective blending across a wide range from 6 to 48 ounces without requiring multiple blades or container size changes.
2Quantity of substance
If a wide-based container is used to process large volumes of working medium, then the blade can handle over 48 ounces, but it creates poor axial flow and suboptimal blending performance for smaller volumes (6-12 ounces)
Solution Approach 1:
Different portions of the blade wing have different geometric properties - the twist creates varying angles of attack at different radial positions. This local variation in blade geometry optimizes axial flow control for the specific container size and volume being processed, whether small (6-12 ounces) or large (48+ ounces), eliminating the need to match container size to volume.
3Productivity
If the blade wing is twisted forwardly, then working medium impinges the upper surface generating low pressure to draw medium from above to below, but this configuration may not optimize all blending scenarios
Solution Approach 1:
The blade wing is segmented into multiple radial zones along its longitudinal length, with each zone having a different angle of attack due to the twist. This segmentation allows different portions of the blade to perform different functions - some zones optimized for drawing medium from above while others handle medium from below - enabling the single blade to effectively process a wide range of volumes from 6 to 48 ounces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The blade design enhances cutting efficiency and axial flow management, allowing for effective blending across a wide range of volumes without the need for multiple blades or container sizes, improving versatility and performance.
Implementation Method 1
the angle of attack may cause the lower surface to deflect the flowing medium away from the airfoil. Such deflection generates low pressures adjacent the upper surface of the airfoil
Implementation Method 2
the working medium may impinge on the lower surface of the airfoil. Consequently, the angle of attack may cause the lower surface to deflect the flowing medium away from the airfoil
Implementation Method 3
the direction of the twisting (forwardly or rearwardly relative to its leading edge) determines the direction of the axial flow

AI summary
A blender blade or blade for being mounted to an interior base of a blender container for rotation about a vertical axis is described. The blade includes at least two blade wings, such that it may include four blade wings. The blade includes a body, first transition section, second transition section, first blade wing and second blade wing. Body includes an aperture, wherein the body is located on a first horizontal plane. First and second transition sections extend at downward angles from opposite sides of the body. First blade wing extends outwardly from the first transition section, wherein the first blade wing is located on a second horizontal plane. Second blade wing extends outwardly from the second transition section, wherein the second blade wing is located on a third horizontal plane. The blade is a one-piece blade and can process approximately 6-48 ounces of working medium.
