QR Code Fault Diagnostics for Industrial Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial display devices used in fault detection for engines, such as diesel engines, often have limited display size and memory, making it difficult for operators to diagnose issues effectively due to the lack of detailed information provided beyond fault codes.
Innovation Solution
A computer-implemented method and system that generates a machine-readable code, such as a QR code, representing fault codes and associated parameters, allowing mobile devices with network connectivity to retrieve detailed information from a database, thereby overcoming the limitations of small display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If display size and memory are reduced to account for cost considerations, then device cost is reduced, but the ability to display meaningful diagnostic information is lost
Solution Approach 1:
The diagnostic information is segmented into two parts: essential fault codes displayed on the industrial display device, and detailed diagnostic information stored in an external database. This segmentation allows the display device to remain simple and cost-effective while still providing access to comprehensive diagnostic data through the machine-readable code that links to the external database.
Solution Approach 2:
The solution transitions from a two-dimensional display constraint to a multi-dimensional information architecture by adding temporal and spatial dimensions. The machine-readable code (QR code) serves as a bridge between the physical display device and the digital database, enabling operators to access detailed information on mobile devices at different locations and times without increasing the physical display device's complexity.
2Device complexity
If only fault codes are displayed on the industrial display device, then device complexity is reduced, but the operator's ability to diagnose issues is insufficient
Solution Approach 1:
A machine-readable code (QR code) is introduced as an intermediary element between the industrial display device and the external database. This intermediary carries encoded diagnostic information that mobile devices can scan and use to retrieve detailed diagnostic data from the database, thereby enhancing diagnostic capability without increasing the complexity of the industrial display device itself.
3Loss of information
If detailed fault information is stored locally on the display device, then information accessibility is improved, but device memory requirements increase
Solution Approach 1:
Detailed diagnostic information is extracted from the industrial display device and stored in an external database. The display device retains only essential fault codes and generates machine-readable codes that link to the external database. This extraction eliminates the need for large local memory storage while ensuring information accessibility through the database connection via mobile devices.

AI summary
Techniques are disclosed for providing information describing a fault code for an object. A display device having an electronic display detects a fault occurrence event in the object. The display device determines a fault code indicative of the fault occurrence event and one or more parameters associated with the fault code. The display device generates a machine-readable code representing the fault code and the one or more parameters.
