Cassette Heating Module Layout for Replaceable Hot Drink Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating modules for hot beverage machines are not optimized for space-saving designs and require numerous connecting lines, leading to increased error rates during installation and maintenance, and are not easily replaceable.
Innovation Solution
A modular design featuring two half-shells that form a cassette-like unit with integrated cavities for the pump, heater, and fluid channels, reducing the need for external connecting lines and allowing for preassembly and easy replacement, along with a pressure relief valve and temperature sensors for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional heating system with separate pump and heater components is used, then the system can be assembled with individual components, but the number of connecting lines increases and installation complexity increases
Solution Approach 1:
The patent combines the pump, heater, and connecting lines into an integrated heating module where the pump housing serves as part of the connecting structure. The pump housing has integrated water inlets and outlets that directly connect to the heater, eliminating the need for separate connecting lines and reducing assembly complexity.
Solution Approach 2:
The pump housing serves multiple functions: it houses the pump mechanism, provides structural support, and acts as a connecting element with integrated water pathways. This multi-functionality reduces the number of separate components needed in the system.
2Ease of repair
If individual components are used for pump and heater, then component replacement is possible, but replacement time increases and service costs increase
Solution Approach 1:
The heating module is designed as a segmented, replaceable unit that can be easily removed and replaced as a complete assembly. The module includes the pump, heater, and all connecting lines as an integrated unit with standardized mounting interfaces, allowing quick replacement without complex disassembly.
3Adaptability or versatility
If multiple separate components are assembled manually, then system flexibility is maintained, but installation error rate increases
Solution Approach 1:
The pump, heater, and connecting lines are pre-assembled and pre-tested as an integrated module before installation. This reduces installation errors by eliminating manual connection steps while maintaining system flexibility through the modular design that can be easily replaced or reconfigured.
