Conical Coffee Grinder Geometry for Quiet, Gentle Bean Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee grinders are noisy and harshly comminute coffee beans, leading to flavor loss and potential blockages, while also consuming high energy.
Innovation Solution
The design of coffee grinders with grinding surfaces having an angle of inclination between 90° and 180°, which cuts coffee beans gently and efficiently, reducing noise and energy consumption, and preventing blockages by effectively cutting foreign substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional grinders use grinding surfaces with traditional angles, then coffee beans are comminuted, but noise is generated and flavor agents are lost
Solution Approach 1:
The patent applies parameter changes by modifying the angle of inclination of the grinding surfaces to a specific range (90° to 180°). This geometric parameter change transforms the grinding mechanism from a traditional crushing action to a cutting action, thereby reducing noise generation and preventing the loss of volatile flavor agents during coffee bean comminution.
2Productivity
If conventional grinders comminute coffee beans harshly, then coffee powder is produced, but blockages occur and energy consumption increases
Solution Approach 1:
The patent modifies the grinding surface angle parameter to create a cutting motion that produces finer, more uniform coffee powder particles. This prevents blockages by ensuring smooth powder flow while maintaining high productivity. The cutting action also reduces energy consumption compared to traditional harsh comminution methods.
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 results in a quieter operation, gentler coffee bean comminution, reduced flavor agent loss, and lower energy consumption, while ensuring complete coffee powder transport and preventing grinder blockages.
Implementation Method 1
the individual coffee beans are moved against the respective grinding surfaces of the teeth and are comminuted by them by means of clamping

AI summary
What is described is a new grinder, which serves to grind coffee beans and which is embodied as conical grinder. To improve the grinding process, the grinding cones and/or grinding ring encompass grinding surfaces that may define an angle of inclination, which may be in each case greater than 90° and smaller than 180°, relative to a tool reference plane.
