Wireless Power Receiver Self-Test Software for Error Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless power transmission systems face issues with undetected errors in wireless power receivers due to software and hardware defects, external conditions, and unpredictable operations, leading to interruptions or cessation of normal system operation, especially when infrequent error conditions are not tested.
Innovation Solution
Implementing automatic self-test software within wireless power receivers that periodically runs self-tests after booting, reports results to wireless power transmitters, and stores operational metrics to detect and correct errors, ensuring continuous system operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual testing is performed for error conditions, then software defects can be detected, but testing cannot be done continuously and infrequent errors may be missed
Solution Approach 1:
The wireless power receiver performs self-testing automatically without requiring manual intervention. The receiver's processor executes test instructions stored in memory to detect errors in its own software and hardware components, enabling continuous monitoring and detection of even infrequent errors while maintaining system reliability.
Solution Approach 2:
The system performs preliminary error detection by continuously executing test instructions before actual operational failures occur. This proactive approach allows the receiver to identify and report errors early, preventing interruptions in power transmission and maintaining system availability.
2Reliability
If automatic self-test software is implemented, then continuous error detection is achieved, but device complexity increases
Solution Approach 1:
The wireless power receiver's processor and memory are designed to serve multiple functions: normal power reception operations and automatic error detection testing. By utilizing existing components for dual purposes, the system achieves continuous monitoring capability without proportionally increasing device complexity.
Solution Approach 2:
The system implements feedback mechanisms where test results are automatically analyzed and reported to the transmitter or stored for later review. This automated feedback loop enables continuous reliability monitoring while keeping the testing software structure manageable through systematic error handling procedures.
