USB Charging Test Control for Simulated Plugging Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current charging tests for portable electronic devices require manual simulation of plugging and unplugging behaviors, leading to low efficiency and subjective, inaccurate results due to the need for manual intervention and lack of objective quantification.
Innovation Solution
A charging test apparatus featuring a first USB interface, a second USB interface, and a control module that simulates various plugging and unplugging behaviors by controlling the connection and disconnection of conductive paths based on preset on/off time parameters, allowing for objective and accurate testing of charging functions without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual plugging and unplugging behaviors are used for charging tests, then the testing process can be performed with simple equipment, but test efficiency is low and results are subjective and inaccurate
Solution Approach 1:
The patent replaces manual mechanical plugging and unplugging operations with an automated control system. The control module automatically controls the connection and disconnection of conductive paths based on preset time parameters, eliminating the need for manual intervention and achieving objective, quantifiable test results while improving test efficiency
Solution Approach 2:
The testing system is designed to perform self-testing through automated control. The control module independently manages the connection timing of multiple conductive paths according to preset parameters, enabling the system to conduct comprehensive charging tests without requiring external manual operation for each test case
2Measurement precision
If manual plugging and unplugging behaviors are used for charging tests, then the equipment structure can be simple, but measurement precision and objectivity are poor
Solution Approach 1:
The patent replaces subjective manual operations with automated electronic control to achieve objective measurement. The control module precisely controls the connection timing of conductive paths based on preset time parameters, enabling accurate reproduction of different plugging behaviors (quick plugging, slow plugging, normal plugging) and achieving quantifiable test results
Solution Approach 2:
The patent segments the charging test into multiple independent conductive paths, each corresponding to different USB pins. The control module can independently control the connection timing of each conductive path, enabling precise simulation of various plugging scenarios and accurate measurement of charging parameters under different conditions
