Spice Grinder with Removable Assembly for Refillable Container Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spice grinders often have permanent connections to the container, making it difficult to refill the container once it is emptied, as the grinding assembly is not easily removable.
Innovation Solution
A spice dispenser with a removable grinding assembly that includes a stationary and rotatable grinder component, allowing for easy attachment and detachment from the container, enabling repeated use and refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the grinding assembly is permanently affixed to the container via snap-fit connection, then the grinding function is stable and reliable, but the container cannot be refilled once emptied
Solution Approach 1:
The grinding assembly is divided into separable components: a grinding head with grinding elements and a container body. The connection interface includes a first feature on the container and a second feature on the grinding assembly that can be selectively engaged and disengaged, allowing the user to separate the grinding assembly from the container for refilling purposes.
Solution Approach 2:
The connection between the grinding assembly and container is made dynamic rather than static. The second feature is movable between engaged and disengaged positions, enabling the connection to transition between stable (engaged) and separable (disengaged) states, thus providing both reliability during use and refillability when needed.
2Adaptability or versatility
If the grinding assembly is permanently connected to the container, then the device structure is simple, but the device cannot be reused after the spice is depleted
Solution Approach 1:
The device is segmented into a reusable grinding assembly and a refillable container. The grinding assembly can be detached from the container, allowing the container to be refilled while keeping the grinding assembly for repeated use, thus improving reusability.
Solution Approach 2:
The grinding assembly is designed with universal coupling features that can attach to compatible containers. The first feature on the container and the second feature on the grinding assembly create a standardized interface that enables the grinding assembly to be reused with different containers, enhancing versatility and reusability.
3Ease of operation
If the grinding assembly is permanently affixed to the container, then the manufacturing process is simple, but the user cannot easily remove the grinding assembly for refilling
Solution Approach 1:
The connection mechanism incorporates movable features that allow easy engagement and disengagement. The second feature can be moved to selectively decouple the grinding assembly from the container, making removal simple for users while maintaining a relatively simple manufacturing process.
Solution Approach 2:
The connection interface uses intermediate coupling features (first feature on container, second feature on grinding assembly) that mediate between the container and grinding assembly. These features provide a simple mechanical interface that is easy to manufacture yet allows easy removal and reattachment by users.

AI summary
A grinder assembly removably connectable to a container of a spice dispenser includes a stationary grinder component and a rotatable grinder component associated with said stationary grinder component to define a grinding chamber between a portion of said stationary grinder component and a portion of said rotatable grinder component. The rotatable grinder component is rotatable relative to said stationary grinder component about a grinding axis. The grinder assembly additionally includes a first feature for coupling the grinder assembly to said container and a second feature movable to selectively decouple the grinder assembly from the container.
