Multi-Pair Blender Blade Structure for Ice Vortex Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blender blade structures fail to efficiently combine cutting, stirring, and mixing functions, particularly when processing frozen drinks, leading to inefficient material movement and incomplete blending.
Innovation Solution
A multi-tiered blade structure with three pairs of blade arms arranged symmetrically about a central axis, each pair designed to move material in specific directions within the blender cup, including chopping, downward, upward, and outward movements, utilizing beveled cutting edges and winglets to create a blending vortex.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single blade structure is used, then the device complexity is low, but the ability to combine cutting, stirring, and mixing functions is insufficient
Solution Approach 1:
The blade structure is divided into three distinct pairs of blade arms (first pair, second pair, third pair), each with different shapes and functions. The first pair is optimized for chopping ice, the second pair for moving material downward and upward, and the third pair for outward material movement. This segmentation allows each blade pair to specialize in specific functions while working together to achieve comprehensive blending performance.
Solution Approach 2:
The multi-pair blade structure collectively performs multiple functions including cutting/chopping, stirring, and mixing. By integrating three different blade pairs with complementary functions, the system achieves versatility in handling various blending tasks (ice chopping, material circulation, vortex creation) without requiring separate devices or blade configurations.
2Productivity
If traditional blade structures are used, then the manufacturing is simple, but the material movement efficiency in blending is insufficient
Solution Approach 1:
Each blade pair is designed with specific local characteristics optimized for its function. The first pair has sharp edges for chopping, the second pair has configurations for downward and upward material movement, and the third pair is shaped for outward material propulsion. This local optimization of blade properties enhances overall material movement efficiency throughout different regions of the blender cup.
Solution Approach 2:
The blade structure creates three-dimensional material flow patterns by moving material in multiple directions (downward, upward, outward, inward) simultaneously at different radial positions. This multi-directional approach in three-dimensional space enhances blending efficiency by creating comprehensive material circulation and vortex patterns that traditional single-plane blades cannot achieve.
3Reliability
If simple blade configurations are used, then the device is easy to manufacture, but the blending completeness for ice-based drinks is insufficient
Solution Approach 1:
The three pairs of blade arms are strategically positioned and shaped to address different aspects of blending completeness. The first pair handles ice chopping, the second pair ensures thorough mixing through upward and downward material movement, and the third pair completes the blending by propelling material outward for final circulation. This segmented functional approach ensures complete blending of ice-based drinks.
Solution Approach 2:
The blade structure creates continuous material circulation through coordinated action of all three blade pairs. Material is constantly moved through different regions of the blender cup in a continuous cycle (chopping → downward movement → upward movement → outward movement → inward movement), ensuring uninterrupted and complete blending action throughout the blending process.
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

AI summary
A blade structure has at least three pairs of blade arms constructed and arranged to create regions of material movement in a blender cup, wherein material is moved outward and upward in a lower region near outer walls of the blender cup, material is moved upward and inward in an upper region near the outer walls of the blender cup, material is chopped and moved downward in a region partway between the outer walls and a central axis of the blender cup, and material is moved downward near the central axis of the blender cup. One embodiment of the blade structure includes a first pair of blade arms arranged in opposition about a common central axis, constructed and arranged for efficient chopping of ice; a second pair of blade arms arranged in opposition about the common central axis, constructed and arranged to move material impinging on a central part of the second pair of blade arms in a downward direction and to move material impinging on a tips of the second pair of blade arms in an upward and inward direction; and a third pair of blade arms arranged in opposition about the common central axis, constructed and arranged to move material impinging on a central portion of the third pair of blade arms in a generally downward direction and arranged to move material impinging on tips of the third pair of blade arms in an outward direction.
