Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of testing electronic devices requires multiple test stations and significant manpower and space, as each station must be reconfigured to accommodate different devices, making the process inefficient in terms of time, labor, and space usage.
Innovation Solution
A multi-function tester that can concurrently test multiple systems of an electronic device using a table assembly with adjustable fixtures, robotic arms equipped with stimulators and sensors, and a computing device to control and monitor the testing process, allowing for simultaneous testing of various functions at a single station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple test stations are used to test different functions of electronic devices, then the testing coverage and functionality are improved, but the space required and manpower needed increase significantly
Solution Approach 1:
The patent implements a universal test station that can perform multiple testing functions (camera, touch screen, WiFi, etc.) through a single device. The test station includes a universal fixture that can accommodate different electronic devices and a multi-functional testing system that can conduct various types of tests without requiring separate dedicated stations for each function.
Solution Approach 2:
The patent combines multiple test stations into a single integrated testing system. Different testing modules (camera test module, touch screen test module, WiFi test module, etc.) are merged into one universal test station, allowing all functions to be tested at a single location rather than requiring multiple separate stations.
2Adaptability or versatility
If multiple test stations are used to test different functions, then the testing capability is improved, but the time required for testing and reconfiguration increases
Solution Approach 1:
The universal test station can switch between different testing functions through software control and automatic configuration. The system includes a computing device that can programmatically select and execute different test procedures for camera, touch screen, WiFi, and other functions, eliminating the need to physically reconfigure entire test stations when switching between device types.
Solution Approach 2:
The test station incorporates dynamic adjustment capabilities through a universal fixture with adjustable positioning mechanisms and a robotic arm that can adapt its position and orientation. The system can dynamically reconfigure its testing parameters and physical arrangement to accommodate different electronic devices and test functions without manual intervention or lengthy reconfiguration processes.
3Measurement precision
If dedicated test stations are used for each function, then the testing precision and specialization are improved, but the device complexity and operational difficulty increase
Solution Approach 1:
The universal test station maintains testing precision for each function through dedicated testing modules that are specifically designed for their respective purposes (camera, touch screen, WiFi). Each module preserves the specialized capabilities needed for accurate testing while being integrated into a single universal platform, avoiding the need for multiple separate specialized stations.
Solution Approach 2:
The test station is segmented into independent functional modules (camera test module, touch screen test module, WiFi test module, etc.) that can be individually activated or deactivated based on the testing requirements. This modular segmentation allows the system to maintain the precision of specialized testing while reducing overall system complexity by only activating the necessary modules for each specific test.
