Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blenders face challenges in efficiently processing varying volumes of liquid mixtures, as traditional blades are limited by container size, with narrow-based containers struggling with volumes over 32 ounces and wide-based containers inadequate for smaller volumes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a narrow-based container is used, then it is suitable for processing smaller volumes of working medium, but it cannot efficiently process larger volumes over 32 ounces
Solution Approach 1:
The blade wings are designed with adjustable angles of attack that can be modified based on the volume of working medium. The blade structure allows dynamic adjustment of wing angles to optimize performance for different container sizes and volumes, enabling the same blade to efficiently process both small and large volumes across narrow and wide-based containers
Solution Approach 2:
The invention changes the operational parameters of the blade by allowing adjustment of the blade wings' angles of attack. This parameter modification enables the blade to adapt its cutting pattern and axial flow characteristics to match different working medium volumes, resolving the contradiction between container adaptability and processing efficiency
2Adaptability or versatility
If a wide-based container is used, then it is suitable for processing larger volumes of working medium, but it is inadequate for processing smaller volumes
Solution Approach 1:
The blade wings can dynamically adjust their angles of attack to optimize performance for different container types. When processing smaller volumes in wide-based containers, the blade wings are positioned at angles that create appropriate cutting patterns and axial flow, ensuring efficient processing regardless of container size mismatch
Solution Approach 2:
The blade design achieves universality by being capable of efficiently processing various volumes (6-48 ounces) in both narrow and wide-based containers. The adjustable blade wing angles allow a single blade design to perform optimally across multiple container configurations, eliminating the need for different blades for different container types
3Ease of operation
If the blade wings are angled in relation to the blade body, then axial flow control is improved, but the blade design complexity increases
Solution Approach 1:
The blade is segmented into multiple independent blade wings that can be individually angled. This segmentation allows each wing to be optimized for specific flow control functions while maintaining overall blade simplicity. The modular wing structure enables independent adjustment of angles without complicating the entire blade design
Solution Approach 2:
The blade wings are designed with asymmetric angles of attack relative to the blade body, with each wing having different angle characteristics. This asymmetric design provides superior axial flow control by creating balanced cutting patterns and pressure distributions, while the symmetry in the overall blade structure maintains design simplicity
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 ability and axial flow control, allowing for efficient blending across a wide range of volumes without the need for multiple containers, improving versatility and efficiency.
Implementation Method 1
the angle of attack may cause the lower surface to deflect the flowing medium away from the airfoil. The amount of deflection is related to the orientation of the airfoil. That is, there is more deflection when there is a high angle of attack and less deflection when there is a low angle of attack. Such deflection generates low pressures adjacent the upper surface of the airfoil.
Implementation Method 2
Such deflection generates low pressures adjacent the upper surface of the airfoil. The lower surface may push flowing medium away from the path of the airfoil, and an absence of flowing medium may thereby be created adjacent to the upper surface of the airfoil. Due to this absence of flowing medium, low pressures are provided adjacent the upper surface, and these low pressure generate the above-discussed lift.
