Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual factory testing is performed by users following manual processes, then test commands can be issued from a terminal, but the process is time-consuming and requires user intervention
Solution Approach 1:
The device performs self-testing by automatically executing test programs stored in its own memory when it detects a test command, eliminating the need for external terminal operations and user intervention. The device powers itself on, runs the tests, and reports results autonomously.
Solution Approach 2:
The testing function is extracted from the manual operation domain and embedded directly into the device's automated control system. The test program is stored within the device's memory, allowing the device to execute tests independently without external control equipment.
2Adaptability or versatility
If manufacturing lines are reconfigured based on different communication cable types, then devices with different connectors can be tested, but this reconfiguration costs time and money
Solution Approach 1:
The testing system achieves universal compatibility with different communication cable types (USB 2.0, USB 3.0, micro USB, etc.) through a single manufacturing line configuration. The device's automated testing capability allows it to work with various cable types without requiring physical reconfiguration of the manufacturing line, as the device itself adapts to different connection protocols.
Solution Approach 2:
The system transitions from static manufacturing line configurations (requiring physical reconfiguration for different cable types) to a dynamic system where the device automatically detects and adapts to different communication protocols through software-based testing procedures.
3Ease of operation
If manual testing processes are used, then users can perform factory tests, but the process is limited by user availability and time
Solution Approach 1:
The device autonomously performs the complete testing sequence including self-powering on, executing test programs from its internal memory, and reporting results. This eliminates dependency on user availability and significantly reduces testing duration from minutes to seconds.
Solution Approach 2:
Test programs are pre-loaded into the device's memory during manufacturing, allowing the device to immediately execute tests without requiring external test software or user setup. This preliminary preparation enables rapid automated testing.
4Adaptability or versatility
If separate manufacturing lines are configured for different cable types, then each device type can be tested with appropriate cables, but this increases manufacturing complexity and cost
Solution Approach 1:
A single manufacturing line is designed to handle multiple device types with different communication cable types through automated testing. The device's ability to autonomously execute tests and adapt to different connection protocols eliminates the need for separate dedicated manufacturing lines for each device type.
Solution Approach 2:
The device's built-in test program and automated control system act as an intermediary that mediates between different communication cable types and the testing process, allowing a single manufacturing line to universally test various device types without direct physical reconfiguration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces testing time, lowers manufacturing costs, and enhances factory efficiency by allowing continuous production without the need for separate lines for different cable types, enabling faster and more efficient device testing.
Implementation Method 1
the testing system uses one or more RFID readers to remotely power on the mobile device and start a test program
Implementation Method 2
A mobile device includes an RFID tag to maintain a power-state indicator of whether the mobile device is in a powered-on state or in a powered-off state
Data Source
AI summary
Device testing using radio-frequency identification (RFID) is described herein. The testing uses one or more RFID readers that interrogate an RFID tag on a mobile device and, in response to the interrogation, receive data from the RFID tag. The one or more RFID readers, in response to receipt of the data from the RFID tag, transmit a command to execute a test program on the mobile device. The results of the test program are then provided by the mobile device.
