Solution Overview

Problem

Existing beverage dispensers lack secure communication protocols to protect telemetry data transmitted over computer networks, exposing them to unauthorized access and potential security breaches.

Innovation Solution

Implementing secure gateways at both the dispenser machine and administrator system to provide message integrity, authentication, and confidentiality, separate from the application layer, and using a message queuer with multiple queues and threads for parallel and scalable processing of telemetry data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If beverage dispensers are connected to administrator systems over computer networks to enable telemetry data transmission, then operational efficiency and maintenance capabilities are improved, but security vulnerabilities increase due to lack of secure communication protocols

Engineering Contradiction:
Improveoperational efficiencyVSAvoidsecurity vulnerabilities
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

A secure gateway is introduced as an intermediary component between the beverage dispenser and the administrator system. The gateway establishes secure communication channels using cryptographic protocols, acting as a mediator that protects telemetry data transmission while enabling operational efficiency improvements through network connectivity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If secure gateways are implemented at both dispenser and administrator system, then data security is improved, but system complexity increases

Engineering Contradiction:
Improvedata securityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The security functionality is segmented into a separate secure gateway component that operates independently from the main beverage dispensing system. This segmentation allows the core dispensing operations to remain simple while security concerns are handled by the specialized gateway module, reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The secure gateway serves as an intermediary layer that handles complex security protocols without requiring the main dispensing system to become more complex. The gateway abstracts security mechanisms, presenting a simple interface to the beverage dispenser while managing cryptographic operations and secure communication protocols.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If message queuer with multiple queues and threads is used for parallel processing, then data processing efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvedata processing efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The message processing system is segmented into multiple independent queues and processing threads. Each queue handles specific message types or sources, and dedicated threads process messages in parallel. This segmentation enables efficient parallel processing while keeping each individual thread and queue relatively simple and manageable.

Inventive Principle:
Principle #1Segmentation

AI summary

The present disclosure is directed to systems and methods for securely providing telemetry data of a dispenser machine to an administrator system via an exposed web service over a computer network. To secure the exposed web service, the systems and methods of the present disclosure provide secure gateways at the dispenser machine and the administrator system that can provide one or more of message integrity, authentication, authorization, and confidentiality. The secure gateways are implemented separate from the applications creating web service request and response messages at the dispenser machine and the administrator system, respectively. Because the secure gateways are implemented separate from the applications creating the web service request and response messages, the applications creating the web service request and response messages can be created and modified without consideration to message security, which is handled transparently by the secure gateways.
