Blender Jar with Tilted Blade Axis to Reduce Air Pockets and Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current household blenders face challenges in processing viscous ingredients due to reduced circulating movement, air pocket formation, and increased power demand, leading to inefficient mixing and vortex generation, especially at high rotational speeds, which results in noise and potential quality issues with textures and flavors.
Innovation Solution
A blender jar with a rotatably attached blender blade assembly, where the rotary axis is tilted from the normal axis of the working surface, enhancing mixing and vortex generation, and a blender base unit with a coupling interface that aligns with the tilt angle, allowing for improved circulation and reduced aggregation of particulate matter without the need for high rotational speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rotational speeds are increased to improve vortex generation and eliminate air pockets, then mixing efficiency is improved, but noise levels increase
Solution Approach 1:
The blender blade assembly is tilted at an angle of 15-30 degrees relative to the horizontal working surface, creating an asymmetric configuration that improves vortex generation and eliminates air pockets without requiring excessive rotational speed, thereby reducing noise while maintaining mixing efficiency
Solution Approach 2:
The tilt angle parameter of the blade assembly is optimized to 15-30 degrees, which changes the flow dynamics and vortex characteristics, allowing effective mixing at lower speeds and thus reducing noise generation
2Productivity
If plungers are used to remove air pockets and enhance circulation, then mixing is improved, but device complexity increases
Solution Approach 1:
The plunger device is completely removed from the system. Instead, the blade assembly itself is tilted at 15-30 degrees to naturally eliminate air pockets and enhance circulation through its asymmetric geometry, simplifying the device while maintaining or improving mixing performance
Solution Approach 2:
The tilted blade assembly automatically eliminates air pockets and enhances circulation through its own rotational motion and geometric configuration, without requiring additional user intervention or auxiliary devices
3Productivity
If more liquid is added to improve vortex and reduce air pockets, then circulation is enhanced, but texture quality deteriorates
Solution Approach 1:
The asymmetric tilt of the blade assembly (15-30 degrees) creates effective vortex generation and air pocket elimination without requiring additional liquid, thereby maintaining the original recipe composition and texture quality while improving circulation
4Productivity
If the blender blade operates at high speed to process viscous ingredients, then processing capability is improved, but power consumption increases
Solution Approach 1:
The tilt angle parameter (15-30 degrees) is optimized to improve flow dynamics and vortex generation, allowing viscous ingredients to be processed effectively at lower rotational speeds, thereby reducing power consumption while maintaining processing capability
