Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brewing devices for coffee or tea machines are not easily mountable or removable for maintenance and cleaning operations, hindering efficient maintenance and cleaning processes.
Innovation Solution
A brewing device with a frame comprising two lateral walls, a cylindrical brewing chamber, and a piston system operated by an electric motor and cam drive mechanism, allowing for rapid attachment and detachment from the machine, along with a magnetic locking mechanism for secure connection and easy release, facilitating maintenance and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the brewing device uses a traditional fastening mechanism, then it provides stable connection during operation, but it becomes difficult and time-consuming to remove for maintenance and cleaning
Solution Approach 1:
The fastening device incorporates a movable lever that can be actuated to release the brewing device. The lever moves between a locked position (securing the brewing device during operation) and an unlocked position (enabling easy removal for maintenance). This dynamic mechanism allows the system to switch between stable connection and easy removal states.
Solution Approach 2:
The fastening device acts as an intermediary mechanism between the brewing device and the machine body. It provides a controlled interface that enables both secure attachment during operation and facilitated removal when needed, mediating between the conflicting requirements of stability and ease of removal.
2Productivity
If the brewing device is designed for easy removal, then maintenance and cleaning become rapid, but the mounting and removal process becomes more complex
Solution Approach 1:
The fastening device is segmented into distinct components: a lever mechanism and corresponding engagement elements on the brewing device. This segmentation allows each component to perform a specific function (locking or unlocking) independently, simplifying the overall design while enabling rapid removal through simple lever actuation.
Solution Approach 2:
The fastening device is designed to be self-actuating through the lever mechanism. When the lever is moved to the unlocked position, the brewing device automatically disengages from its locked state without requiring additional tools or complex operations, enabling rapid removal for maintenance.
3Device complexity
If the brewing device uses a simple mounting mechanism, then it reduces device complexity, but it may compromise the security and reliability of the connection
Solution Approach 1:
The fastening device acts as an intermediary that provides both simplicity and security. The lever mechanism offers a simple user interface (single lever movement) while internally providing secure engagement through properly designed engagement elements that ensure reliable connection during operation.
Solution Approach 2:
The fastening mechanism is self-securing through its design. When the lever is in the locked position, the engagement elements automatically secure the brewing device without requiring additional fastening actions, providing both simplicity and reliability.
