Solution Overview
Problem
Current fault diagnosis methods, such as light path diagnostics, face challenges including high power consumption, maintenance costs, and complexity in identifying failing units in electronic and mechanical assemblies, particularly in portable devices.
Innovation Solution
The method involves pre-arranging visual codes associated with units in an assembly, allowing for image acquisition and decoding to identify and locate target units, reducing costs and complexity by using low-power consumption display technologies like E-ink displays and QR codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light emitting diode (LED) is used for fault diagnosis and unit location, then intuitive prompt and unit identification are improved, but power consumption, maintenance cost, and device complexity increase
Solution Approach 1:
The patent replaces the physical LED indicator with a digital image copy displayed on a screen. The camera captures an image of the assembly, and the processing unit generates a digital representation showing the location of the target unit or fault condition. This digital copy eliminates the need for physical LEDs while providing the same identification function.
Solution Approach 2:
The patent substitutes the mechanical/electrical LED system with an optical-digital system. Instead of using light-emitting components that require power and have limited lifespan, the system uses image capture and digital processing to achieve the same diagnostic purpose, thereby eliminating power consumption and maintenance issues associated with LEDs.
2Ease of operation
If light emitting diode (LED) is used for fault diagnosis and unit location, then intuitive prompt and unit identification are improved, but maintenance cost and service life are worsened

3Ease of operation
If light emitting diode (LED) is used for fault diagnosis and unit location, then intuitive prompt and unit identification are improved, but wiring complexity and device volume increase
Solution Approach 1:
The patent employs a multi-functional approach where the camera serves multiple purposes: it captures images for both fault diagnosis and unit location identification. The same imaging system is used to identify target units during assembly and to detect fault conditions, eliminating the need for separate LED indicators and their associated wiring for each function.
