Grinder Storage Cup Quick-Change Mechanism Using Claw and Snap Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric grinders require a large rotating force to snap-fit the storage cup and housing together, making it cumbersome to mount and dismount the storage cup, which is inconvenient for users.
Innovation Solution
A grinder with easy-to-replace storage cups featuring a mounting base with a claw and snap ring mechanism that allows for power transmission, combined with a self-locking device for secure attachment and detachment, enabling quick and easy installation and removal of storage cups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the storage cup is snap-fitted with the housing via a rotary snap-fit method, then the storage cup can be securely attached to the housing, but a large rotating force is required and the operation becomes cumbersome
Solution Approach 1:
The mounting base is divided into two functional parts: a bottom plate with a claw for power transmission and an outer ring for positioning and support. This segmentation allows the claw to engage with the snap ring for secure attachment while the outer ring provides structural support, enabling easy installation without requiring large rotating forces
Solution Approach 2:
Instead of using a traditional rotary snap-fit where the storage cup rotates to lock onto the housing, this invention inverts the mechanism by using a claw that embeds into a snap ring through direct insertion. The power unit then rotates the claw to drive the snap ring, reversing the traditional rotation direction and making the operation simpler and less cumbersome
2Adaptability or versatility
If multiple storage cups are equipped, then users can grind different granules conveniently, but the device complexity increases
Solution Approach 1:
The mounting base with the claw-snap ring mechanism is designed as a universal interface that can accommodate multiple storage cups with different granules. The standardized mounting structure allows users to easily swap between storage cups containing different materials (pepper, salt, spice mixes) without requiring different mounting mechanisms, thus providing versatility while maintaining simple device structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution facilitates easy mounting and dismounting of storage cups, allowing users to switch between different granules conveniently and providing a stable, reliable connection that enhances user convenience and efficiency.
Implementation Method 1
The power unit works to drive the claw to rotate, so as to drive the snap ring to rotate; and the rotating snap ring drives the grinding component to work
Implementation Method 2
When the storage cup is inserted into the mounting base, the claw is embedded into the snap ring
