Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If maintenance personnel manually troubleshoot home box-shaped devices, then they can identify fault causes, but troubleshooting time is prolonged and user convenience deteriorates
Solution Approach 1:
The terminal device performs self-diagnosis by automatically executing fault detection instructions, determining service types, and analyzing fault causes without requiring maintenance personnel intervention. The device presents detection results to users directly, enabling self-service fault identification that eliminates travel time and manual troubleshooting delays.
Solution Approach 2:
The system pre-configures multiple service types (voice, broadband, video, etc.) and their corresponding fault detection content before actual faults occur. When a fault detection instruction is received, the terminal device quickly matches the instruction against pre-configured service types and executes the appropriate detection routine, avoiding time-consuming manual analysis.
2Measurement precision
If comprehensive fault detection is performed across all service types, then fault detection accuracy improves, but device complexity and operation difficulty increase
Solution Approach 1:
The fault detection system is segmented into distinct service types (voice service, broadband service, video service, etc.), each with its own detection content and parameters. This segmentation allows the terminal device to present users with a simplified menu of service options rather than a complex comprehensive test, making operation easier while maintaining thorough detection coverage when specific service types are selected.
Solution Approach 2:
Instead of requiring users to initiate comprehensive fault detection across all possible service types, the system allows users to select only the specific service type they are experiencing issues with. This partial action approach simplifies user operation by presenting only relevant detection options while still achieving accurate fault detection for the selected service.
3Measurement precision
If multiple fault detection methods are provided for different service types, then detection precision improves, but device complexity increases
Solution Approach 1:
The terminal device integrates a universal fault detection framework that can handle multiple service types (voice, broadband, video, etc.) through a common architecture. The device receives fault detection instructions, automatically determines the service type, and executes appropriate detection routines within the same system, achieving multi-functionality without proportionally increasing complexity. The presentation module also provides unified output interfaces for different detection results.

AI summary
The present disclosure discloses a fault detection method and device. The method includes: receiving, by a terminal device, a fault detection instruction entered by a user, and determining a service type of a to-be-detected fault according to the fault detection instruction; determining fault detection content according to the service type; starting to detect the fault detection content to obtain a detection result; and presenting the detection result. In this way, whether in a period of deploying or in a period of using the terminal device, the fault detection instruction is directly triggered when there is a need to determine whether the terminal device is faulty, and then the fault detection content corresponding to the service type of the to-be-detected fault is detected, which effectively implements a self-detection capability of the terminal device, increases a fault locating speed, and improves fault detection accuracy.
