Blender Pushing Unit to Prevent Blade Separation and Food Spillage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blenders face issues where the blade assembly can separate from the container during removal, causing processed food to flow out due to excessive rotation and a lack of proper engagement mechanisms.
Innovation Solution
Incorporating a pushing unit with first and second push portions on the base and container, respectively, that engage to smoothly lift the container unit away from the base, preventing excessive rotation and food leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container unit is rotated relative to the base for removal, then the container unit can be detached from the base, but excessive rotation occurs causing the blade assembly to separate from the container
Solution Approach 1:
The patent introduces a pushing unit consisting of a first push portion on the base and a second push portion on the blade assembly as an intermediary mechanism. When the container unit is rotated for removal, the first push portion pushes the second push portion, causing the blade assembly to move upward relative to the container. This intermediary pushing action prevents the blade assembly from separating from the container while still allowing smooth removal of the container unit.
2Ease of operation
If the container unit is rotated relative to the base for removal, then the container unit can be detached from the base, but processed food flows out from the container
Solution Approach 1:
The pushing unit acts as an intermediary mechanism that prevents food loss. By pushing the second push portion upward when the container unit is rotated for removal, the blade assembly is elevated relative to the container, creating a barrier that prevents processed food from flowing out of the container.
3Reliability
If a blocking structure is used to prevent excessive rotation, then the blade assembly is blocked, but the structure becomes more complex
Solution Approach 1:
The patent employs a self-service mechanism where the pushing unit automatically activates during the container unit removal process. As the container unit is rotated, the first push portion naturally pushes the second push portion, causing the blade assembly to move upward. This self-activating mechanism prevents excessive rotation and food loss without requiring additional complex control structures or components.

AI summary
A blender includes abase and a container unit mounted rotatably and detachably on the base. The container unit includes a container, and a blade assembly disposed on a bottom portion of the container. The base includes a first push portion adjacent to the blade assembly which has a second push portion. When the container unit is rotated relative to the base until the second push portion contacts with the first push portion, the first push portion pushes upward the second push portion as the container unit is continuously rotated relative to the base so as to move the container unit upwardly and away from the base.
