Coffee Machine Modular Assembly Design for Simplified Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee machines have complex structures that are inconvenient to assemble and result in low production efficiency due to limited operation space within the housing.
Innovation Solution
A coffee machine design featuring a detachable support system for the brewing body and sealing plate assemblies, allowing for independent mounting and simplification of the structure, which facilitates easier assembly and disassembly, and reduces the size of the body for improved accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the coffee machine uses a traditional integrated structure with all components mounted directly in the housing, then the structure is compact, but the assembly process becomes complex and time-consuming due to limited operation space
Solution Approach 1:
The coffee machine is divided into modular components: the brewing body (3), support (2), water-inlet sealing plate assembly (4), and water-outlet sealing plate assembly (5) are separate detachable modules that can be assembled independently before being mounted to the housing (1), simplifying the overall assembly process while maintaining structural integrity
Solution Approach 2:
The brewing body (3) and sealing plate assemblies (4, 5) are extracted from the housing (1) as separate detachable components, allowing them to be assembled and tested independently outside the housing before final installation, thereby improving assembly convenience without increasing overall device complexity
2Productivity
If the brewing body and sealing plate assemblies are mounted directly in the housing, then the structure is simplified, but the assembly time increases due to limited operation space
Solution Approach 1:
The brewing body (3) and sealing plate assemblies (4, 5) are pre-assembled on the support (2) outside the housing (1) where adequate operation space is available, completing complex sub-assembly operations beforehand to reduce the time required for final installation into the housing
3Ease of operation
If the body size is reduced for better accessibility, then the operation space is improved, but the mounting and sealing requirements become more stringent
Solution Approach 1:
The sealing system is segmented into separate sealing plate assemblies (4, 5) that can be independently mounted and replaced, allowing for easier maintenance and ensuring reliable sealing even in the compact brewing body (3) design
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 design optimizes the assembly process by allowing the body and sealing plate assemblies to be mounted separately, reducing assembly time and enhancing disassembly convenience, thereby improving efficiency and simplifying the structure for easier maintenance.
Implementation Method 1
the first power source is mounted on the support, and the first power source is configured for driving the first sealing plate to act
Implementation Method 2
an output end of the water-outlet sealing plate assembly is configured for sliding in the brewing cavity
Implementation Method 3
one end of the driving plate is rotatably mounted in the body through a first rotating shaft
Implementation Method 4
the other end of the driving plate is hinged with one end of the intermediate plate, and the other end of the intermediate plate is hinged with the first sealing plate through a second rotating shaft
Implementation Method 5
an end portion of the second rotating shaft is located in the first guide slot, the first sealing plate is provided with a guide post, and an end portion of the guide post is located in the second guide slot
