Solution Overview

Problem

Current hot beverage preparation devices, such as coffee machines, face challenges in simplifying the determination of error causes, relying on manual operator intervention and technical understanding for troubleshooting, which can lead to transmission errors and inefficiencies in diagnosing and resolving issues.

Innovation Solution

Incorporating a coding device to encode error data into a machine-readable code, such as a 2D barcode, allowing for direct processing and transmission to receiving devices like smartphones, enabling automatic error diagnosis and contact with customer service without manual intervention, and facilitating software updates for post-launch error sources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual operator intervention is used to transmit error codes, then device complexity is reduced, but transmission errors increase and productivity decreases

Engineering Contradiction:
Improvetransmission accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the manual mechanical transmission method (operator reading and communicating error codes) with an automated optical system. The coding device generates machine-readable codes (barcodes or QR codes) that can be automatically scanned and transmitted to mobile devices, eliminating human intervention in the data transmission process and ensuring accurate, error-free transmission of error codes and diagnostic information.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service diagnostics by allowing operators to automatically scan and transmit error codes to their mobile devices without requiring assistance from customer service representatives. The hot beverage preparation device autonomously generates and displays the coded error information, which can then be retrieved and processed by the operator using a smartphone or other mobile device with a camera.

Inventive Principle:
Principle #25Self-service

2Productivity

If manual error code transmission is used, then device complexity is reduced, but loss of time increases due to operator intervention

Engineering Contradiction:
Improvetroubleshooting efficiencyVSAvoiddiagnosis time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically generating and displaying the error code in machine-readable format as soon as an error occurs, without requiring any manual intervention. The coding device immediately encodes the error code and displays it on the device screen or a nearby display, preparing the information for immediate scanning and transmission, thereby eliminating any delay in the diagnostic process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the time-consuming manual process of reading and communicating error codes with an automated optical scanning system. The machine-readable code can be instantly scanned by a mobile device camera, and the error information can be automatically transmitted to customer service or stored for later analysis, significantly reducing the time required for error diagnosis and troubleshooting.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If error data is not encoded in machine-readable format, then device complexity is reduced, but ease of operation worsens due to manual interpretation requirements

Engineering Contradiction:
Improveerror diagnosis easeVSAvoidcoding system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the manual interpretation of error codes with an automated optical recognition system. The coding device generates machine-readable codes (barcodes or QR codes) that can be automatically scanned and decoded by mobile devices, eliminating the need for operators to manually read, interpret, and communicate error codes. This substitution of manual mechanical processes with automated optical-electronic processes significantly improves ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system creates a visual copy of the error code in machine-readable format that can be easily captured and transmitted. Instead of requiring operators to memorize or manually transcribe error codes, the system generates a visual representation (barcode or QR code) that can be directly scanned and copied by a mobile device camera, ensuring accurate transmission without manual intervention.

Inventive Principle:
Principle #26Copying
