Diagnostic Boot Mode for Self-Service Terminal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-service terminals often enter an unstable state, leading to continuous rebooting and preventing technicians from accessing diagnostic tools, making it difficult to diagnose faulty components.
Innovation Solution
A diagnostic boot mode is initiated using a unique hardware component, allowing the system to enter an alternate boot sequence where individual hardware and software modules can be activated and deactivated, enabling technicians to isolate and repair faulty components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system enters continuous rebooting state, then the system attempts to recover from errors, but diagnostic tools cannot be accessed and faulty components cannot be identified
Solution Approach 1:
The patent implements a preliminary action by detecting the presence of a diagnostic boot device before the normal boot sequence executes. This detection occurs during the initial boot phase, allowing the system to preemptively switch to diagnostic boot mode before the unstable state can manifest. By performing this detection and mode switching action in advance, the system ensures that diagnostic tools remain accessible even when continuous rebooting would otherwise occur, thereby resolving the contradiction between system stability and diagnostic accessibility.
2Ease of repair
If individual hardware and software modules are activated and deactivated for diagnosis, then faulty components can be isolated, but the system requires a special diagnostic mode
Solution Approach 1:
The patent employs an intermediary approach by introducing a diagnostic boot device as a mediator between the system and the diagnostic process. This device serves as a trigger that initiates the alternate boot sequence without requiring complex manual configuration or multiple boot mode switches. The diagnostic boot device simplifies the interaction by providing a clear, detectable signal that automatically transitions the system into diagnostic mode, thereby reducing the operational complexity despite the presence of multiple boot sequence variations.
3Ease of operation
If the system uses a unique hardware component to trigger diagnostic mode, then diagnostic access is enabled, but the system requires additional hardware detection logic
Solution Approach 1:
The patent implements self-service by enabling the system to automatically detect the presence of the diagnostic boot device and autonomously switch to diagnostic boot mode without requiring external intervention or complex detection algorithms. The system's existing boot sequence infrastructure is leveraged to perform the detection and mode switching automatically, thereby simplifying the user operation while managing the detection logic within the normal system operations rather than adding separate complex detection mechanisms.
