Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding apparatuses for coffee beans struggle to accurately measure and deliver predefined doses, leading to contamination issues and aroma loss due to residual beans.
Innovation Solution
A grinding apparatus with a removably connected hopper and an integrated dosing device, featuring weighing means and feed mechanisms that allow precise measurement and delivery of beans to the grinding device, enabling easy hopper replacement and minimizing residual beans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If volumetric dosing devices are used to measure coffee beans, then the dosing process is simplified, but the measurement precision is insufficient because beans of different origins have different shapes and sizes
Solution Approach 1:
The patent replaces volumetric dosing mechanisms with a weighing mechanism that directly measures the mass of coffee beans. This substitution eliminates the inaccuracies caused by volumetric measurement of irregularly shaped beans while maintaining operational simplicity through automated weight-based control.
2Device complexity
If a fixed hopper is used in the grinding apparatus, then the structure is simplified, but the adaptability is reduced because the user cannot easily replace the hopper to change bean types
Solution Approach 1:
The patent divides the coffee storage system into a removable hopper component and a fixed grinding apparatus. This segmentation allows the hopper to be easily removed and replaced for different bean types while keeping the main grinding structure simple and fixed.
3Adaptability or versatility
If the hopper is removed to change bean types, then the adaptability is improved, but residual beans remain in the grinding device causing contamination and aroma loss
Solution Approach 1:
The patent incorporates a cleaning mechanism that automatically removes residual beans from the grinding device before the hopper is removed. This preliminary cleaning action prevents contamination and aroma loss when changing bean types, enabling the hopper to be removed for adaptability without leaving residues.
4Measurement precision
If additional weighing components are added to measure bean doses, then the measurement precision is improved, but the device complexity and overall size increase
Solution Approach 1:
The patent integrates the weighing mechanism directly into the existing hopper structure, combining the measurement function with the storage component. This merging approach provides precise bean dose measurement without adding separate, bulky weighing components, thus maintaining compact device size.

The apparatus ensures accurate measurement and delivery of coffee beans, preventing contamination and aroma loss, while allowing for easy hopper replacement and maintaining the grinding device clean.
Implementation Method 1
weighing means associated with the hopper and configured to weigh the hopper and its contents in order to measure a quantity of beans present in, or released by, the at least one hopper
Implementation Method 2
feed means, disposed inside the at least one hopper and selectively drivable by means of drive means disposed outside the at least one hopper in order to feed the beans toward an exit aperture
