Solution Overview

Problem

Automatic beverage preparation machines with electromagnetic-induction, continuous-flow fluid heaters face difficulties in maintenance due to complex casing designs that require disassembly and access to hard-to-reach areas, leading to time-consuming and space-intensive cleaning and replacement processes.

Innovation Solution

The design features of the automatic beverage preparation machine allow for immediate access to the electromagnetic-induction, continuous-flow fluid heaters, enabling easy maintenance by decoupling and repositioning components from outside the casing without tilting the machine, using hinged hatches and screw-release mechanisms to facilitate cleaning and reassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If the casing is designed with complex geometry and hidden fasteners for aesthetic reasons, then the appearance quality is improved, but the ease of maintenance deteriorates

Engineering Contradiction:
Improvecasing geometryVSAvoidheater accessibility
Core Design Contradiction:
ShapeVSEase of repair

Solution Approach 1:

The casing is divided into modular sections with removable panels that provide access to the heater. This segmentation allows the aesthetic outer casing to be separated from the maintenance-access panels, enabling easy heater removal without compromising the overall design appearance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The heater is extracted as a separate, independently removable component from the casing. Quick-release mechanisms allow the heater to be quickly removed from the casing for maintenance, eliminating the need to disassemble complex casing structures.

Inventive Principle:
Principle #2Taking out (Extraction)

2Volume of moving object

If the heater is housed inside the casing in hard-to-reach positions, then the space utilization is improved, but the intervention time increases

Engineering Contradiction:
Improvecasing space utilizationVSAvoidmaintenance intervention time
Core Design Contradiction:
Volume of moving objectVSLoss of time

Solution Approach 1:

Quick-release clamps and pre-positioned access panels are installed during manufacturing to enable rapid heater removal. These preliminary preparations eliminate the need for time-consuming disassembly during maintenance operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The heater mounting system transitions from fixed to dynamic/removable. The heater can be quickly moved in and out of the casing using spring-loaded clamps or bayonet connectors, reducing maintenance time while maintaining compact housing.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If the machine requires tilting or overturning for heater maintenance, then the liquid leakage risk is reduced, but the operational complexity increases

Engineering Contradiction:
Improveliquid leakageVSAvoidmaintenance procedure simplicity
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Quick-connect fluid couplings and sealed access panels serve as intermediaries that allow heater removal without tilting the machine. These components enable maintenance while keeping the machine in its normal upright position, preventing liquid leakage and simplifying the procedure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The heater and fluid connections are designed to be self-contained with integrated sealing mechanisms. The heater can be removed and reinstalled without requiring the machine to be tilted or without causing liquid leakage, making the system self-protecting during maintenance.

Inventive Principle:
Principle #25Self-service

AI summary

In an automatic beverage preparation machine (1) operable to dispense a beverage in a container (9), a fluid for preparing the beverage is heated by means of a electromagnetic-induction, continuous-flow heater (25) having a tubular body (27) delimiting a flow path form the fluid to be heated; the tubular body (27) has an end outlet segment leading into a chamber (K) closed by a plug-shaped body (37A, 37B), which is removable to allow access to the flow path; the plug- shaped body (37 A, 37B) is arranged outside a casing (2) or is uncouplable and extractable from the casing (2) through an opening (45) formed in the casing (2) to allow direct access from the outside to the flow path.
