Reconfigurable Touchscreen Beverage Dispenser Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage dispensers lack adaptability, making it difficult to change the number of keys on the interface device and reprogram beverages without manually altering the device or switching syrups, leading to inflexibility in managing beverage options and inventory.
Innovation Solution
A reconfigurable control system with a control panel that includes sensing regions and a control unit, allowing for user-defined configurations, enabling the sequencing of beverage fluid dispensing and the creation of customized beverages by controlling valves based on user input, with features like adjustable flow rates and solenoid blocks for precise fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed interface device with predetermined buttons is used, then the device structure is simple and reliable, but the adaptability to change beverage options and reprogram keys is poor
Solution Approach 1:
The control panel transitions from a static fixed-button interface to a dynamic reconfigurable interface. The sensing regions can be programmatically assigned to different beverages and functions, allowing the interface to adapt its configuration based on the dispensing system's current state and beverage inventory without requiring physical hardware changes.
Solution Approach 2:
The control panel is designed with universal sensing regions that can serve multiple functions. Each sensing region can be programmed to represent different beverages, cup sizes, or control functions depending on the system configuration, making a single control panel suitable for multiple beverage dispensing scenarios and establishments with different menu requirements.
2Ease of operation
If manual reconfiguration of interface devices is required to change beverages, then the device structure remains simple, but the ease of operation and time required for reprogramming is poor
Solution Approach 1:
The system enables self-service reconfiguration through automated programming capabilities. When beverage inventory changes or new beverages are added, the system can automatically update the control panel assignments based on sensor inputs from the beverage reservoirs, eliminating the need for manual intervention by technicians to reprogram the interface device.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors monitor beverage inventory levels and types in the reservoirs, and this information is fed back to the control unit, which then automatically updates the control panel configuration. This closed-loop feedback system ensures the interface always reflects the current beverage availability without manual reconfiguration.
3Adaptability or versatility
If the number of buttons is fixed during installation, then the manufacturing and installation process is simple, but the adaptability to different establishment requirements is poor
Solution Approach 1:
The control panel uses a dynamic assignment system where sensing regions are not permanently tied to specific beverages but can be programmatically assigned during installation or operation. This allows a single manufactured control panel to adapt to different establishment requirements by configuring which sensing regions correspond to which beverages based on the specific menu offerings.
Solution Approach 2:
The system changes the operational parameters of the control panel through software configuration rather than physical manufacturing variations. The control unit can be programmed with different beverage mappings, allowing the same hardware to serve different establishments with different beverage menus without requiring custom-manufactured control panels for each location.
