Beverage Machine Start-Up Control for Low-Energy Readiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage preparation machines with electric heaters consume significant energy when left in standby mode to maintain readiness, leading to inefficiency and environmental waste, and existing automatic shut-down systems result in lengthy start-up times when reactivating the machine.
Innovation Solution
A control unit in the beverage preparation machine allows users to store beverage requests during the start-up mode, enabling automatic processing once the machine enters the operative mode, eliminating the need for users to wait for the start-up process to complete before making a request, and reducing energy consumption by managing power modes effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the machine is maintained in operative mode to avoid start-up delays, then the response time for beverage preparation is improved, but energy consumption increases significantly
Solution Approach 1:
The control unit stores beverage requests in advance during standby mode, so that when the machine transitions to operative mode, the beverage preparation can begin immediately without requiring the user to wait for the full start-up sequence to complete. This preliminary storage of request information eliminates the perceived wait time while allowing the machine to be in low-power standby mode.
2Loss of energy
If automatic shut-down systems are implemented to save energy, then energy waste is reduced, but the machine requires lengthy start-up procedures including pre-heating and self-cleaning
Solution Approach 1:
The control unit performs preliminary actions by storing the beverage request information in memory during standby mode. When the user activates the machine, the control unit immediately retrieves the stored request and initiates beverage preparation without requiring the user to manually input the request after start-up, thereby simplifying the user's interaction despite the machine being shut down.
3Productivity
If the machine is left switched on permanently to avoid any start-up delays, then beverage preparation readiness is improved, but unnecessary energy consumption occurs during periods of inactivity
Solution Approach 1:
The machine dynamically transitions between standby mode and operative mode based on user activation. The control unit manages this dynamic state change, allowing the machine to be in low-power standby during inactivity and automatically transition to full operative mode when a beverage request is detected, optimizing both energy consumption and readiness.
Solution Approach 2:
Upon detecting a beverage request during standby mode, the control unit preliminarily stores the request information and initiates the transition to operative mode, preparing the system in advance so that beverage preparation can begin as soon as the machine is ready, minimizing the user's perceived waiting time.

AI summary
An electric beverage preparation machine has : an arrangement (5', 5'', 200, 500, 510, 600, 700, 800) for processing one or more beverage ingredients to dispense a beverage; a control unit (2) connected to the beverage processing arrangement for controlling the processing of one or more beverage ingredients; a beverage user-selector (2b, 2b'), such as a push or touch or toggle button or touch screen, for requesting a beverage, the selector being connected to the control unit; an operative mode in which such machine is immediately ready to process one or more beverage ingredients; and a start-up mode in which such machine is not ready to process one or more beverage ingredients and is brought into the beverage preparation mode from a low electric consumption standby mode or from an electrically switched off state. The control unit (2) is arranged to store in the start-up mode any beverage request via the beverage user-selector (2b, 2b') and initiate automatically the processing of one or more beverage ingredients upon entering the operative mode after leaving the start-up mode.
