Blender Jug Bottom Rib Design to Reduce Suction and Laminar Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing blender jugs cause an interruption in the blending process when the hand blender's blender foot suctions onto the bottom, requiring users to forcibly pull it off, disrupting the material feeding to the blending tool.
Innovation Solution
A rib is integrated into the inner surface of the blender jug's bottom to reduce suction and break laminar flow, allowing the blender foot to sit freely and enhancing the blending process by deflecting food towards the blending tool.

Engineering Contradiction Analysis
1Force
If the blender foot is allowed to suction onto the bottom of the blender jug, then the blender foot is held firmly in position, but the feeding of material to the blending tool is interrupted and the blending process stops
Solution Approach 1:
The bottom surface of the blender jug is segmented by adding ribs that divide the surface into multiple zones. This segmentation prevents the blender foot from forming a complete seal with the bottom surface, allowing material to continue flowing underneath while maintaining sufficient suction to hold the blender foot in position.
Solution Approach 2:
The ribs are strategically positioned on the bottom surface to create local variations in surface topology. These localized structural features selectively reduce suction in specific areas while maintaining it in others, ensuring continuous material flow paths remain open beneath the blender foot.
2Stability of the object's composition
If the blender foot sits firmly on the bottom surface, then stability is improved, but laminar flow develops below the opening which reduces blending efficiency
Solution Approach 1:
The ribs create turbulence and disrupt laminar flow patterns in the material flowing beneath the blender foot. By introducing these structural obstacles, the material flow becomes more chaotic and mixing-enhancing, improving blending efficiency while the overall blender foot position remains stable.
Solution Approach 2:
The ribs convert the potentially harmful laminar flow that reduces blending efficiency into beneficial turbulent flow. The structured disruption caused by the ribs transforms smooth, inefficient material flow into chaotic, mixing-promoting flow patterns that enhance 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
The rib minimizes suction force and improves blending efficiency by ensuring continuous material flow and processing, with optimal results achieved at an angle between 70° and 90° and a radial or curved longitudinal extension.
Implementation Method 1
it can break any laminar flow that can develop in an area below the opening at the lower side of the blender foot of the hand blender so that the blending process is enhanced
Implementation Method 2
the provided rib reduces the suction effect between the bottom of the blender jug and the blender foot

AI summary
The present invention relates to a blender jug for a hand blender, with a bottom (1) that is surrounded by an uprising wall. When using a hand blender with such a jug this can result in the blender foot of the hand blender wanting to suck on the bottom of the blender jug. This can result in the blending process to come to a stop. To avoid this, it is proposed to provide the bottom (1) on its surface (2) facing the inner volume of the jug with at least one rib (3) that rises from the surface (2) of the bottom (1).
