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 leaks, making them difficult to clean and use safely.
Innovation Solution
A blade holder assembly with a cup base, blade holder, and handle system featuring a rotary fastener mechanism that allows for easy mounting and demounting, secure locking, and convenient cleaning, utilizing a locator and guide slot for precise alignment and a waterproof ring for fluid containment.
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 waterproofing is improved, but the blade holder becomes hard to rotate due to high friction force
Solution Approach 1:
The patent replaces the traditional screw-thread connection mechanism with a snap-fit connection system. The blade holder includes positioning protrusions that engage with corresponding positioning grooves on the cup body, eliminating the need for threading and high-friction silicone rings while maintaining waterproof sealing through integrated sealing structures.
Solution Approach 2:
The patent changes the connection parameters from threaded engagement to elastic deformation-based snap-fit engagement. The blade holder and cup body utilize elastic materials and deformation characteristics to achieve secure connection without high friction, allowing easy rotation and attachment/detachment while maintaining waterproof integrity.
2Ease of operation
If the blade holder and cup body are not screwed tightly, then ease of operation is improved, but water leakage occurs at the connecting point
Solution Approach 1:
The patent employs curved or rounded positioning protrusions and grooves that guide the blade holder into proper alignment with the cup body during attachment. The curved sealing surfaces ensure uniform contact and sealing pressure distribution, achieving reliable waterproofing without requiring excessive tightening force.
3Stability of the object's composition
If the blade holder structure is made complex to improve stability, then stability is improved, but the structure becomes more complex and harder to clean
Solution Approach 1:
The patent segments the blade holder assembly into distinct functional components: a blade holder body, detachable blade assembly, positioning protrusions, and integrated sealing elements. This segmentation allows each component to perform its specific function with simple geometry, maintaining stability through modular positioning features while enabling easy disassembly for cleaning and reducing overall structural complexity.
