Quick-Release Mixing Hook Sealing for Viscous Ingredients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance mixing arrangements are inefficient for handling high viscosity ingredients, complex in construction, and time-consuming for assembly, disassembly, and cleaning, with issues related to leakage and tool-dependent attachment mechanisms.
Innovation Solution
A household appliance mixing arrangement featuring an open-top mixing container with a through hole for a drive arrangement and a hook that rotates horizontally, utilizing a quick-release-hook-attachment mechanism and sealing to prevent leakage, allowing easy attachment and detachment of the hook without tools, and facilitating easy cleaning and ingredient addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a through hole is provided in the mixing container for the drive arrangement, then the hook can be rotated within the mixing container, but ingredients may escape through the through hole causing leakage
Solution Approach 1:
A sealing element is introduced as an intermediary component between the drive arrangement and the mixing container wall. This sealing element prevents ingredient leakage through the through hole while allowing the drive arrangement to rotate the hook, thus resolving the contradiction between enabling hook rotation and preventing ingredient escape.
2Reliability
If a complex attachment mechanism is used to secure the hook to the drive arrangement, then the connection is strong and reliable, but assembly and disassembly become time-consuming and tool-dependent
Solution Approach 1:
The attachment mechanism is segmented into modular components including a quick-release coupling system with separate locking and releasing elements. This segmentation allows the hook to be securely attached during operation while enabling rapid tool-free detachment when needed, resolving the contradiction between attachment reliability and assembly speed.
Solution Approach 2:
The attachment mechanism incorporates dynamic elements such as spring-loaded locking pins or bayonet-style couplings that automatically engage during attachment and can be quickly released with a simple motion. This dynamic design provides strong secure connection during mixing while allowing rapid disassembly without tools, addressing both reliability and time efficiency requirements.
3Reliability
If the hook is permanently attached to the drive arrangement, then the connection is strong, but cleaning and hook replacement become difficult and time-consuming
Solution Approach 1:
The permanent attachment is replaced with a segmented detachable connection system that maintains strong connection during operation but allows easy separation for cleaning and maintenance. The quick-release mechanism enables the hook to be firmly secured during mixing while being easily detached for thorough cleaning or replacement, resolving the contradiction between connection strength and maintenance ease.
