Product reservoir validation system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for product dispensers with replaceable reservoirs are ineffective against unauthorized use and counterfeiting, as mechanical and electrical key systems can be bypassed, leading to incorrect product dispensing and contamination risks.
Innovation Solution
A product dispenser system that incorporates a data storage device in the replaceable reservoir and a controller with bi-directional communication, using logic processors and encryption to authenticate the reservoir and prevent unauthorized use, ensuring only authorized and genuine products are dispensed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical or electrical key systems are used to prevent unauthorized product dispensing, then product compatibility is ensured, but these systems can be bypassed or counterfeited by users
Solution Approach 1:
The patent replaces mechanical key systems and simple electrical tags with a microprocessor-based authentication system. The reservoir includes a microprocessor that communicates with the dispenser controller through encrypted bi-directional communication, moving from mechanical/electrical physical keys to electronic intelligence-based authentication that can verify product identity and prevent counterfeiting.
Solution Approach 2:
The patent introduces a data storage device and communication interface as intermediaries between the reservoir and dispenser controller. This intermediary layer enables complex authentication protocols, including encrypted communication and verification of reservoir identity, preventing direct bypassing that occurs with simple mechanical or electrical key systems.
2Reliability
If keyed systems with tags or indicia are used to authenticate refill containers, then product authorization is verified, but these can be circumvented by applying counterfeit tags
Solution Approach 1:
The patent replaces physical tags and indicia with electronic authentication stored in a microprocessor within the reservoir. Instead of visual or simple electrical tags that can be copied, the system uses encrypted electronic verification of the reservoir's identity, making counterfeiting significantly more difficult as it requires replicating functional electronic authentication rather than simple physical markings.
Solution Approach 2:
The patent addresses counterfeiting by implementing authentication that verifies the genuine identity of the reservoir through encrypted communication. The system checks for valid authentication credentials that cannot be easily copied or replicated, ensuring that counterfeit tags or unauthorized containers cannot be mistaken for genuine products.
3Object-affected harmful factors
If replaceable reservoirs are used to eliminate biofilm formation, then hygiene is improved, but users can bypass authentication and install unauthorized refills
Solution Approach 1:
The patent replaces simple mechanical keyed systems with microprocessor-based authentication that maintains the replaceable reservoir benefit while preventing bypassing. The electronic authentication system verifies each reservoir's identity before allowing installation and use, ensuring that only authorized, hygienically-filled reservoirs can be used while preventing users from installing unauthorized refills that could compromise hygiene.
Solution Approach 2:
The patent implements bi-directional communication between the reservoir and dispenser controller, enabling the system to verify reservoir authentication status before allowing operation. This feedback mechanism ensures that only properly authenticated reservoirs can be installed and used, maintaining hygiene standards by preventing unauthorized refill installation while still allowing legitimate replaceable reservoir usage.

AI summary
A system and method of authenticating a replaceable product reservoir for use in a product dispenser includes incorporating a data storage device into the replaceable product reservoir where the dispenser control reads data from the storage device to verify that the correct replaceable product reservoir has been installed in the product dispenser.
