Beverage Dispenser Sensor-Based Centering for Splash-Free Autofill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern appliances face challenges in efficiently dispensing water and ice into containers of varying sizes and shapes without splashing or taking excessive time, and existing solutions lack the ability to automatically fill containers while in use and provide user feedback for accurate placement.
Innovation Solution
A beverage dispensing system with sensors and a controller that detects container location, provides user feedback, and automatically dispenses liquid once the container is centered, using machine learning to analyze images and adjust dispensing rates to prevent splashing and overflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the dispenser operates at slower speeds to minimize splashing, then splashing is reduced, but the dispensing time increases and productivity decreases
Solution Approach 1:
The system dynamically adjusts the dispensing speed based on real-time container position detection. The controller modifies the dispensing rate adaptively - using slower speeds when the container is in optimal position and faster speeds when positioned suboptimally, thereby resolving the contradiction between preventing splashing and maintaining productivity
Solution Approach 2:
The system employs sensors to continuously monitor container position and provides real-time feedback to the controller. This feedback loop enables the controller to adjust dispensing parameters dynamically, optimizing both splashing prevention and dispensing speed by responding to actual container positioning conditions
2Productivity
If the dispenser operates more quickly to improve productivity, then dispensing time is reduced, but the risk of spillage increases
Solution Approach 1:
The system performs preliminary container position detection and verification before initiating the dispensing operation. This advance assessment allows the controller to pre-adjust dispensing parameters to appropriate speeds, ensuring both high productivity and low spillage risk from the outset of the dispensing process
Solution Approach 2:
The dispensing speed is made dynamic rather than fixed, allowing the system to operate at higher speeds when container positioning is optimal while automatically reducing speed when positioning is suboptimal, thus achieving both productivity improvement and spillage prevention
3Device complexity
If the dispenser cavity is designed for fixed size constraints, then device complexity is reduced, but adaptability to different container sizes decreases
Solution Approach 1:
The system uses automated sensor-based container detection and positioning assistance, allowing the dispenser to automatically adapt to different container sizes without requiring complex mechanical adjustments or multiple cavity configurations. The self-servicing positioning system maintains simplicity while achieving high adaptability
Solution Approach 2:
The sensing and control system serves multiple functions: detecting container presence, determining container size, guiding container positioning, and adjusting dispensing parameters. This multi-functionality allows a single cavity design to accommodate various container sizes without increasing overall system complexity
4Device complexity
If manual positioning and monitoring is used, then device complexity is minimized, but ease of operation and user feedback decrease
Solution Approach 1:
The system incorporates sensors that detect container position and provide automated feedback through the user interface, guiding users on proper container placement. This automated feedback mechanism improves ease of operation without requiring complex mechanical positioning aids, maintaining system simplicity while enhancing user experience

AI summary
A beverage dispensing system for an appliance may include a dispenser area defined within the appliance having a shelf configured to receive a container; a dispenser configured to release liquid into the container in the dispenser area; at least one sensor configured to detect a location of the container within the dispenser area; a user interface configured to display feedback to a user; and a controller configured to receive sensor data, determine whether the container is centered within the dispenser area based on the sensor data, and after a predefined waiting period, instruct the dispenser to dispense liquid to fill the container.
