Blender Container Geometry and Spout Layout for Cleaner Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional blender containers are inefficient in blending due to their round or square shapes, lead to noise from the blender, and have issues with material discharge through the spout, with the spout often not being effectively closed during blending.
Innovation Solution
A blender container with an arcuate wall and intersecting straight walls positions the blade's axis closer to the arcuate wall for efficient mixing, incorporates a noise-baffling skirt with fingers, and features a pouring spout located 20-30% from the top for efficient discharge, with a cover that completely seals the spout using a plug assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional round or square container configurations are used, then manufacturing is simple, but blending efficiency is poor
Solution Approach 1:
The container employs an asymmetric configuration with one arcuate wall and three straight walls, creating an irregular polygonal cross-section. This asymmetric shape optimizes blending efficiency by positioning the blade axis closer to the arcuate wall, enhancing material circulation patterns while maintaining manufacturability through simple geometric forms.
2Ease of operation
If the spout is positioned at the top corner for easy pouring, then discharge is convenient, but material congeges around the spout causing misdirection
Solution Approach 1:
The spout is repositioned to a specific location on the arcuate wall, approximately 20-30% down from the top rim, rather than at the top corner. This localized positioning optimization ensures material flows smoothly through the spout without congregating, improving transfer efficiency while maintaining pouring convenience through strategic placement.
3Reliability
If the cover is designed to close only the container opening, then structure is simple, but the spout remains open during blending
Solution Approach 1:
The cover is designed with dual functionality: it seals the main container opening and incorporates an integrated spout closure mechanism. A removable plug within the cover provides the spout closure function, allowing the single cover component to perform both sealing operations effectively during blending operations.
4Object-affected harmful factors
If no sound reduction features are added to the container, then device complexity is low, but noise from the blade is distracting
Solution Approach 1:
A skirt with noise-baffling fingers is introduced as an intermediary element between the blade and the external environment. These fingers act as acoustic barriers that absorb and deflect sound waves generated by the rotating blade, reducing noise transmission while maintaining a relatively simple overall container structure.
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
Enhances blending efficiency, reduces noise, and ensures complete material discharge through the spout without misdirection, while effectively closing the spout during blending operations.
Implementation Method 1
Fingers extend from the skirt into the opening and are spaced from each other to baffle the noise of the blender

AI summary
A container (11) for a blender includes a base surface (13) and a blade (20) which is rotatable on an axis above the base surface (13). An arcuate wall (14) and two generally straight walls (15, 16) extend upwardly from the base surface (13) and terminate at the upper end of container (11). The axis of rotation of the blade (20) is closer to the arcuate wall (14) than it is to the generally straight walls (15, 16). A skirt (25) extends downwardly from the base surface (13) and has an opening. Sound baffling fingers (32) extend from the skirt (25) and into the opening. A spout (40) is formed at the intersection of two of the walls (14, 15, 16), the spout (40) having an entry point located approximately twenty to thirty percent of the height of the walls (14, 15, 16) from the upper end of the container (11). A handle (34) is positioned opposite to the spout (40) and a cover (12) includes a plug (55) to close the spout (40).
