Adaptive Beverage Dispenser Sanitation Using Flow-Rate Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage dispensers rely on time-based sanitation cycles, which do not account for varying product demand levels and unscheduled shutdowns, leading to inefficient sanitation and potential microbial growth.
Innovation Solution
A method and apparatus that adjust the sanitation cycle initiation based on actual flow rates, using a flow meter and controller to delay or initiate sanitation according to baseline flow rates, product type, and unscheduled events, incorporating a radio frequency identification tag for product data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If time-based sanitation cycles are used, then sanitation is performed regularly, but sanitation frequency does not adapt to varying product demand levels
Solution Approach 1:
The system uses a flow meter to continuously monitor product flow rate and provides feedback to the controller. The controller compares actual flow rate to baseline flow rate and adjusts sanitation cycle initiation accordingly, creating a closed-loop feedback system that adapts sanitation frequency to actual usage conditions without requiring complex manual intervention
Solution Approach 2:
The system automatically monitors flow rate, determines when sanitation is needed based on predefined criteria, and initiates sanitation cycles without user intervention. The controller self-adjusts the sanitation schedule based on flow meter data, eliminating the need for manual tracking or user input while adapting to varying demand patterns
2Loss of energy
If sanitation cycles are extended during high demand periods, then waste is reduced and equipment lifespan is extended, but microbial growth risk increases
Solution Approach 1:
The sanitation cycle timing is made dynamic rather than static. The system continuously monitors flow rate and adjusts the sanitation initiation time based on actual product dwell time conditions. When flow rate exceeds baseline (indicating shorter dwell time and lower microbial risk), sanitation is delayed. When flow rate is low or zero (indicating longer dwell time and higher microbial risk), sanitation is initiated promptly, creating a dynamic adaptation to real-time conditions
Solution Approach 2:
The system changes the timing parameter of sanitation cycles based on flow rate conditions. By monitoring actual flow rate against baseline flow rate, the system adjusts the sanitation initiation time parameter dynamically, extending cycles when safe to do so and shortening them when necessary, thereby optimizing the balance between resource efficiency and hygiene safety
3Reliability
If sanitation is performed immediately after unscheduled shutdowns, then hygiene is maintained, but sanitation scheduling complexity increases
Solution Approach 1:
The controller is pre-programmed with logic to detect shutdown conditions and automatically initiate sanitation cycles in response to detected events. The system prepares by monitoring operational status and immediately executes pre-planned sanitation action when a shutdown is detected, ensuring hygiene maintenance without requiring complex real-time decision-making or manual intervention

Function Achieved in This Case
This approach ensures more efficient sanitation by aligning with demand levels and accounting for unscheduled shutdowns, reducing waste and extending sanitation cycle intervals when demand is high, while maintaining safety standards.

AI summary
A method for altering an initiation time of an apparatus sanitation cycle based upon a base line flow rate. The method may include determining an actual flow rate through the apparatus, comparing the actual flow rate to the base line flow rate, and delaying the initiation time of the apparatus sanitation cycle if the actual flow rate exceeds the base line flow rate.
