Blender Blade Holder Assembly With Rotary Lock and Leak Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blender blade holder assemblies face issues with complex structures, inconvenient operation, and safety risks due to high friction and potential leakage, making them difficult to clean and use safely.
Innovation Solution
A blade holder assembly with a handle connected to a rotary fastener that aligns with a convex button on the cup base, allowing for easy locking and unlocking, featuring a locator for precise positioning and a waterproof ring for secure operation, facilitating easy assembly, disassembly, and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blade holder and cup body are connected by screw-thread connection with waterproof silicone ring, then the connection is secure and waterproof, but the friction force is high making it hard to rotate and operate
Solution Approach 1:
The connection mechanism is divided into separate functional elements: the convex button provides positioning, the rotary fastener with fastening members provides locking, and the waterproof ring provides sealing. This segmentation allows each element to perform its specific function without the drawbacks of integrated screw-thread connection.
Solution Approach 2:
Instead of using threaded connection that requires rotation to tighten, the patent uses a rotary fastener that locks by rotating fastening members along the convex button edge to engagement positions. The operation is inverted from threading to clicking-into-place, reducing friction and effort.
2Ease of operation
If the blade holder and cup body are connected by screw-thread connection, then the connection can be detached for cleaning, but if not screwed tightly it may leak water creating safety risks
Solution Approach 1:
The fastening members automatically engage with the convex button when the handle is rotated to the correct position, and the locator ensures proper alignment. This self-aligning mechanism eliminates the need for manual tightening while ensuring reliable connection.
Solution Approach 2:
The manual screw-thread tightening mechanism is replaced with a rotary fastener system that uses geometric engagement (fastening members along the convex button edge) and positioning elements (locator) to achieve secure connection without requiring tight screwing.
3Stability of the object's composition
If the blade holder structure is made complex to improve stability, then the stability increases, but the operation becomes inconvenient and cleaning difficult
Solution Approach 1:
The blade holder assembly is segmented into modular components (blade holder, handle, locator, rotary fastener, waterproof ring) that can be easily assembled and disassembled. This modularity maintains stability through precise geometric engagement while simplifying operation and cleaning.
Solution Approach 2:
The handle is extracted as a separate operational element that can be removed independently. This allows the blade holder to remain stable during operation while enabling easy access for cleaning without dealing with complex integrated structures.
