Mobile Device Self-Diagnosis Using Built-In Actuators and Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device diagnostics require human input, leading to time-consuming and error-prone processes, as they rely on manual operation and subjective judgments about device functionality, which hampers efficient reuse and processing of non-functional devices.
Innovation Solution
Integration of built-in actuators and sensors within mobile devices enables self-diagnosis through automated processes, where pre-defined control signals are used to activate actuators, and sensors measure responses, comparing these to reference signals to determine device functionality without human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual human operation is used for device diagnostics, then human judgment can assess device functionality, but the process becomes time-consuming and error-prone
Solution Approach 1:
The mobile device performs self-diagnosis by automatically activating its own actuators with pre-defined control signals and measuring their responses using built-in sensors. The device compares measured responses to reference signals to determine functionality without requiring human operation or judgment, thereby eliminating time loss while maintaining or improving diagnosis accuracy through objective automated measurement.
2Ease of operation
If manual human operation is used for device diagnostics, then device functionality can be assessed, but the process becomes prone to human error and subjective judgment
Solution Approach 1:
The patent replaces the mechanical system of manual human operation with an automated electronic control system. The processing means automatically generate control signals, activate actuators, measure responses via sensors, and compare results to reference signals. This substitution eliminates subjective human judgment and operational errors while maintaining ease of operation through automated execution of the diagnosis protocol.
3Productivity
If automated self-diagnosis using built-in actuators and sensors is implemented, then diagnosis speed and accuracy improve, but device complexity increases
Solution Approach 1:
The patent leverages the multi-functionality principle by utilizing existing built-in actuators and sensors for dual purposes: their primary functions for device operation and their secondary function for self-diagnosis. The processing means repurposes these existing components to generate control signals, measure responses, and compare results against reference signals stored in memory, thereby improving diagnosis efficiency without significantly increasing device complexity.

AI summary
According to an aspect, there is provided a method for self-diagnosing a mobile device comprising at least one or more actuators, one or more sensors and a display. The method comprises, first, feeding a pre-defined control signal to a first actuator of the mobile device and measuring, in response to the feeding, a first electric signal using a first sensor of the one or more sensors. Then, the first electric signal is compared to one or more reference signals associated with the first actuator and the pre-defined control signal. If the first electric signal fails to match the one or more reference signals according to one or more pre-defined criteria, negative diagnosis is indicated to use of the mobile device using one or more of a display of the mobile device and one or more actuators of the mobile device.
