Solution Overview

Problem

Existing coffee machine grinders require multiple designs to accommodate different types of coffee machines, leading to increased production and storage costs due to a fixed removal opening and actuator position, which limits their adaptability.

Innovation Solution

The adjusting wheel is mounted on a ring-shaped holder that can be adjusted and fixed in any position relative to the housing, allowing for a standard grinder to be used across various coffee machines by positioning the adjusting wheel optimally with respect to the removal opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the actuator and adjusting wheel are fixed in a specific position relative to the removal opening, then the grinder can be properly adjusted, but multiple grinder designs are required for different coffee machine types, increasing production and storage costs

Engineering Contradiction:
Improvecompatibility with different coffee machine typesVSAvoidnumber of grinder designs
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjusting wheel is mounted on a ring-shaped holder that can be rotated and fixed at different angular positions relative to the removal opening. This dynamic positioning allows a single grinder design to adapt to different coffee machine types by adjusting the wheel's angular position to match available space and drive wheel locations.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The ring-shaped holder with adjustable angular positioning enables the adjusting wheel to serve multiple functions across different coffee machine configurations. A single grinder design can be universally applied to various machine types by simply rotating the holder to the appropriate angle, eliminating the need for multiple specialized designs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the adjusting wheel is fixed in position, then the structure is simple, but it cannot be adapted to different space configurations in various coffee machines

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidadjustment complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The ring-shaped holder allows the adjusting wheel to be dynamically positioned at different angular orientations. The holder can be rotated to match the available space in different coffee machine installations, providing adaptability without significantly increasing operational complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjusting wheel is pre-mounted on the ring-shaped holder, which is designed to be easily rotatable and fixable at various positions. This preliminary configuration allows for quick adaptation to different machine types without requiring complex assembly or disassembly operations during installation.

Inventive Principle:
Principle #10Preliminary action

AI summary

The grinder has an adjusting unit formed by a drive wheel (15) e.g. worm wheel, that is arranged coaxial to a screw part (7). The drive wheel cooperates with a setting wheel (16) e.g. worm gear. The setting wheel is fastened to a housing (2), and a supply opening is arranged at the housing for supplying coffee beans. A path guide opening (13) guides path of coffee beans grinded between grinding disks, and the setting wheel is arranged at a holder (17) that is attached at the housing, where the holder is adjustable and fixed in any position with respect to the housing.
