Matrix Code Error Resolution for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often present cryptic error messages that users find difficult to understand, making it challenging for them to resolve error conditions effectively.
Innovation Solution
The electronic device detects error conditions and includes a matrix code in error messages, which can be scanned by a reader device to access information for resolving the issue, allowing for dynamic generation of codes that include specific device information and user support details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional error messages are used, then the error information is transmitted to users, but the users find the messages cryptic and difficult to understand
Solution Approach 1:
The patent introduces matrix codes as an intermediary between the error information system and the user. Instead of directly presenting cryptic error messages to users, the system encodes error information into matrix codes that can be scanned and decoded by a reader device, which then retrieves and presents human-readable troubleshooting information from a server. This intermediary mechanism bridges the gap between machine-generated error codes and user-comprehensible instructions.
Solution Approach 2:
The patent transitions error information from a one-dimensional text-based presentation to a two-dimensional matrix code format. By encoding error information into a visual matrix code that can be scanned by a camera or image sensor, the system adds a spatial dimension to error communication. This dimensional change enables the error information to be efficiently transmitted and then expanded into comprehensive troubleshooting guides through the scanning and decoding process.
2Ease of operation
If comprehensive error resolution information is provided to users, then users can resolve errors effectively, but the system complexity increases due to dynamic code generation and information management
Solution Approach 1:
The patent extracts the complex information management and processing functions from the electronic device itself and relocates them to an external server. The electronic device only needs to generate and display simple matrix codes, while the server handles the storage, retrieval, and presentation of comprehensive troubleshooting information. This extraction of complex functions reduces the device complexity while maintaining effective error resolution capabilities.
Solution Approach 2:
The system implements a self-service mechanism where the matrix code contains encoded information that automatically guides the user through the error resolution process. When scanned, the code retrieves the appropriate troubleshooting information without requiring manual intervention from support personnel. The system serves itself by using the error information encoded in the matrix code to automatically provide the correct resolution steps to the user.
3Productivity
If multiple sets of error resolution information are provided for unsuccessful attempts, then users can continue troubleshooting, but the number of matrix codes and information sets increases
Solution Approach 1:
The patent creates a universal matrix code system where a single matrix code structure can serve multiple functions. The same basic matrix code format can encode different error types and resolution steps, and the server can provide multiple sets of troubleshooting information for different scenarios. This multi-functionality allows the system to handle numerous error cases and multiple resolution attempts without proportionally increasing the number of unique matrix codes required.

AI summary
An electronic device detects occurrence of an error condition and selects a matrix code to include in an error message to transmit to a display device based on the error condition. A reader device decodes the displayed matrix code to present information regarding resolution of the error condition. The electronic device may select the matrix code by looking up the error condition in a table or by dynamically generate the matrix code. In various implementations, the electronic device may determine that the information regarding resolution of the error condition has been utilized to unsuccessfully resolve the error condition. If so, the electronic device may select and transmit and additional matrix code that may be decoded by the reader device to access and present an additional set of information regarding resolution of the error condition or to initiate an electronic device support request.
