Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Milk frothers in existing technologies suffer from residue accumulation, leading to bacterial growth and organoleptic deterioration, and are difficult to clean effectively.
Innovation Solution
A milk frother design featuring a steam fitting and hollow longitudinal body with variable permanent connections, allowing for easy disassembly and inspection, facilitating cleaning and preventing damage or loss of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the milk frother components are permanently assembled together for sale, then the device structure is simplified and easier to manufacture, but the inner parts become difficult to access for cleaning
Solution Approach 1:
The milk frother is divided into separable components including a removable milk suction tube and a detachable mixing chamber assembly. The milk suction tube can be completely removed from the longitudinal body, and the mixing chamber can be separated from the steam fitting, allowing easy access to all inner surfaces for cleaning while maintaining a compact assembled structure for manufacturing and use.
2Ease of operation
If the milk frother components are made separable after purchase, then cleaning access is improved, but the device complexity increases and components may get damaged or lost
Solution Approach 1:
The milk suction tube is extracted as a completely removable component from the longitudinal body, allowing it to be taken out for thorough cleaning without disassembling other parts. The mixing chamber assembly can also be separated from the steam fitting by simple manual manipulation, providing cleaning access without requiring complex disassembly procedures or special tools.
Solution Approach 2:
The milk suction tube is designed to nest within the longitudinal body when assembled, and the mixing chamber nests within the steam fitting assembly. This nested structure allows compact storage and simple reassembly while maintaining ease of separation for cleaning, reducing the risk of component loss.
3Reliability
If complex cleaning solutions with multiple cycles are implemented, then cleaning effectiveness is improved, but the operation time and energy consumption increase
Solution Approach 1:
The separable component design allows users to perform preliminary manual rinsing and inspection of inner surfaces before placing the components in a dishwasher. The completely removable milk suction tube can be quickly rinsed immediately after use, preventing residue accumulation and reducing the need for extended automated cleaning cycles.

AI summary
A milk frother comprising a steam fitting with a steam flow dispenser, a homogenization element, a hollow longitudinal body having a seat engaging the steam fitting, a steam, air and milk mixing chamber, an air access channel, and a milk access channel both to the mixing chamber. The steam fitting has steam access to the mixing chamber, the hollow longitudinal body has an outlet for frothed milk from the mixing chamber, and the outlet has a dispensing end engaging with the homogenization element. A permanent connection provided between the hollow longitudinal body and the steam fitting, having a variable configuration between a first engagement and a disengagement configuration between the steam fitting and the engagement seat. A second permanent connection provided between the hollow longitudinal body and the homogenization element, having a configuration that is variable between a second engagement and a disengagement configuration between the homogenization element and the dispensing end.
