Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blender jars lack an efficient design for homogenizing and accelerating the processing of foodstuffs, as their geometries do not effectively stabilize or destabilize the vortex formed by the rotating knife, leading to suboptimal mixing performance.
Innovation Solution
A blender jar with a globally tubular geometry featuring a regular pentagonal contour at the free end, allowing the lid to be positioned in five different configurations, and incorporating baffle elements to enhance vortex interaction and processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional cylindrical or square geometries are used for the blender jar, then the manufacturing is simple and the structure is easy to produce, but the vortex formation is inefficient leading to poor homogenization performance
Solution Approach 1:
The patent applies asymmetry by changing the jar geometry from conventional symmetric cylindrical or square shapes to an asymmetric pentagonal contour. This asymmetric shape creates more effective vortex formation and destabilization during blending, improving processing efficiency and homogenization performance while maintaining manufacturability through standard molding techniques.
Solution Approach 2:
The patent changes the geometric parameter of the jar cross-section from circular or quadrangular to pentagonal. This parameter change in the contour shape fundamentally alters the vortex dynamics inside the jar, creating more efficient mixing patterns that accelerate foodstuff processing while remaining compatible with conventional manufacturing methods.
2Device complexity
If conventional geometries are used for the blender jar, then the design is simple and aesthetically standard, but the vortex stabilization and destabilization effects are insufficient for optimal mixing
Solution Approach 1:
The patent employs asymmetry by adopting a pentagonal contour instead of conventional symmetric shapes. This asymmetric geometry creates superior vortex stabilization and destabilization effects during operation, significantly improving mixing reliability and homogenization performance while adding only moderate geometric complexity that remains manufacturable.
Solution Approach 2:
The patent achieves equipotentiality by creating five identical elements in the pentagonal profile that are evenly distributed around the central axis. This symmetric arrangement of identical elements ensures balanced vortex formation and consistent mixing performance across all regions of the jar, enhancing overall mixing reliability.
3Productivity
If a pentagonal profile is implemented at the free end of the side wall, then the vortex formation is optimized for faster and more efficient homogenization of foodstuffs, but the lid positioning requires precise alignment among five possible positions
Solution Approach 1:
The patent applies universality by designing the lid and jar interface with five identical positioning possibilities. The lid can be correctly positioned at any of the five angular positions around the pentagonal contour, making the closing operation universal and independent of the jar's rotational orientation. This eliminates alignment complexity while maintaining the performance benefits of the pentagonal geometry.
Solution Approach 2:
The patent uses asymmetry in the pentagonal profile to optimize vortex formation for faster processing, while the symmetric repetition of the five sides ensures that the lid interface remains rotationally symmetric, allowing easy closing from any position.
4Productivity
If the pentagonal profile is extended over the whole height of the jar, then the vortex efficiency is maximized throughout the entire processing volume, but the manufacturing complexity and material usage increase
Solution Approach 1:
The patent applies local quality by implementing the pentagonal profile specifically at the free end of the side wall where it most effectively influences vortex formation and mixing performance. This localized application provides sufficient homogenization efficiency improvement without the increased material volume and manufacturing complexity that would result from extending the pentagonal geometry throughout the entire jar height.

AI summary
This jar includes a bottom wall, bearing rotary mechanical elements for processing foodstuffs. This jar also includes a side wall extending transversely from the bottom wall while delimiting with the latter a free space in which the rotary elements act on the foodstuffs to be processed, this side wall having, opposite the bottom wall, a free end for introducing the foodstuffs into the free space. In order to make the use of this jar simple and efficient, the free end of the side wall has a regular pentagonal profile.
