Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee machine group heads, which are either fixed or movable via friction, face issues with adapting to varying cup heights, leading to potential splashing and reduced service life due to frictional losses from repeated movement.
Innovation Solution
A moving structure for the group head utilizing a magnetic conductive plate and magnets to securely position the group head, reducing frictional resistance and allowing for easy adjustment and prolonged service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the group head is made movable up and down to adapt to different cup heights, then the adaptability is improved, but frictional loss increases and service life decreases
Solution Approach 1:
The patent replaces the traditional friction-based mechanical fixing system with a magnetic field-based fixing system. Magnets are embedded in the moving plate that interacts with magnetic conductive material in the fixed plate, creating a non-contact holding force that eliminates frictional wear during movement and maintains reliability over extended service life while preserving adaptability to different cup heights
2Device complexity
If friction is used to fix the group head, then the structure is simple, but repeated movement causes frictional loss and functional degradation
Solution Approach 1:
The patent substitutes the friction-based mechanical contact system with a magnetic field-based non-contact system. The magnetic attraction between magnets in the moving plate and magnetic conductive material in the fixed plate provides holding force without physical friction, eliminating energy loss while maintaining structural simplicity
3Stability of the object's composition
If a fixed group head is used, then the structure is stable, but it cannot adapt to varying cup heights causing spilling or improper placement
Solution Approach 1:
The patent transforms the fixed group head into a dynamic system where the group head can move vertically along the brewing unit. The magnetic fixing mechanism allows controlled movement to different positions while maintaining stable holding at each position, achieving both adaptability to different cup heights and structural stability during operation
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 magnetic attraction-based system effectively reduces direct friction, allowing for smooth and durable up-and-down movement of the group head, enhancing usability and extending its operational lifespan.
Implementation Method 1
the moving plate is fixedly attached to the magnetic conductive plate by means of the magnets on the moving plate. In the absence of an external force, the moving plate remains stationary due to attraction of the magnets

AI summary
This application provides a moving structure for a group head and a coffee machine. The moving structure for a group head includes a front plate, a magnetic conductive plate, magnets, and a moving plate. The front plate is provided with a guide opening, and the magnetic conductive plate is fixed to a rear side portion of the front plate. The magnets are assembled on the moving plate, and the moving plate is slidably assembled in the guide opening and corresponds to the magnetic conductive plate. The group head is fixed on the moving plate, and in the absence of an external force, the group head remains stationary due to attraction of the magnets. In this way, direct friction is reduced, and service life can be effectively prolonged.
