Tester Device Error Source Identification via UPnP Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for identifying the source of errors in customer devices, such as signal interference or outdated software, often rely on external devices that operate differently and require multiple tools, leading to reduced accuracy and increased time for diagnosis.
Innovation Solution
A tester device that directly receives information from the customer device, using protocols like UPnP and OMA DM, to analyze and identify errors, thereby reducing the need for external devices and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external devices are used to identify error sources, then diagnostic coverage can be extended, but measurement precision deteriorates due to operational differences between external and customer devices
Solution Approach 1:
The customer device performs self-diagnosis by executing diagnostic code locally and generating test results internally. This self-service approach ensures that the device under test evaluates its own operations using its native components, thereby maintaining measurement precision while achieving comprehensive diagnostic coverage through automated self-assessment capabilities.
Solution Approach 2:
Instead of using external devices to test the customer device, the invention inverts the testing paradigm by having the customer device test itself through embedded diagnostic code. This inversion resolves the contradiction by ensuring that the same device used for operation is also used for testing, eliminating operational differences that would compromise measurement precision.
2Adaptability or versatility
If multiple external devices are used for comprehensive testing, then diagnostic capability is enhanced, but device complexity increases
Solution Approach 1:
The customer device is designed with multi-functionality, serving both as the operational device and as its own testing instrument. By embedding diagnostic code within the customer device itself, the system eliminates the need for multiple external testing devices, thereby reducing device complexity while maintaining comprehensive testing capability through the device's dual role.
Solution Approach 2:
The invention merges the customer device and the testing device into a single integrated system. The diagnostic code is embedded within the customer device, combining the functions of operation and testing in one device. This merging eliminates the need for separate external testing equipment, reducing overall system complexity while preserving comprehensive diagnostic capability.
3Reliability
If external devices perform diagnostics, then error detection can be achieved, but loss of time increases due to setup and operation of multiple tools
Solution Approach 1:
Diagnostic code is embedded within the customer device during manufacturing, performing preliminary preparation for future diagnostics. This preliminary action ensures that the testing capability is already integrated and ready, eliminating the time required for setting up external devices and enabling immediate error detection whenever needed, thus reducing diagnosis time while maintaining reliable error detection capability.
