Self-Test Application for Electronic Apparatus Error Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in diagnosing and identifying the cause of errors in electronic apparatuses, as existing methods require physical connection to a test computer, and current devices only inform users of errors without specifying their origin, whether internal or external.
Innovation Solution
An electronic apparatus equipped with a self-test application that executes a test routine to diagnose errors, determines the cause based on test results, and communicates the findings to external authenticated devices, allowing for autonomous error analysis and reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a test computer is used to diagnose errors in the electronic apparatus, then the cause of the error can be identified, but the user must carry the electronic apparatus to a place where the test computer is present, making it difficult to test the electronic apparatus when the test computer is absent
Solution Approach 1:
The electronic apparatus performs self-diagnosis by executing a self-test application that automatically identifies and tests functions related to the error. The system uses its own processing unit and memory to run test routines without requiring external test equipment, enabling the apparatus to diagnose its own errors and determine whether they are caused by internal factors or external environments.
2Loss of information
If the electronic apparatus only displays that an error has occurred, then the user is informed of the error, but the user cannot be informed of the cause of the error (internal or external)
Solution Approach 1:
The self-test application is divided into multiple test routines, each targeting specific functions or components. The application segments the error diagnosis process into distinct test cases that can be executed independently, allowing systematic identification of error causes without requiring an overly complex monolithic system.
Solution Approach 2:
The system implements feedback mechanisms where the self-test application executes test routines and receives test results that indicate whether functions are operating normally or abnormally. Based on these feedback results, the application determines the cause of the error and provides informed guidance to the user about whether the issue stems from internal factors requiring service or external environmental factors.
3Ease of operation
If a self-test application is executed to diagnose errors autonomously, then the user can test the electronic apparatus without external test equipment, but the system must identify and execute appropriate test routines from multiple options
Solution Approach 1:
The self-test application is pre-configured with multiple test routines that are prepared in advance, each designed to test specific functions or components. When an error is detected, the application refers to predetermined information about the error and automatically selects and executes the appropriate pre-prepared test routine, eliminating the need for real-time complex decision-making during error diagnosis.

AI summary
In an electronic apparatus, a processor executes a program stored in memory to perform essential functions. In the event of an error related to these functions, a self-test application is triggered. The processor may identify a relevant test routine from a set of routines, conduct tests on the function using the identified routine, and communicate the test results to a display. Accordingly, when an error occurs while the electronic apparatus is operating, the electronic apparatus can inform a user and a manufacturer of a cause of the error.
