Electronic Device Shipping Mode Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting a shipping mode in electronic devices lack closed-loop monitoring, leading to instances where devices fail to enter the shipping mode but are still shipped, resulting in user experience issues when these devices cannot be turned on or used normally.
Innovation Solution
Implementing a method where the electronic device receives a shipping instruction from a host computer and sends a feedback instruction confirming successful entry into the shipping mode, or indicating failure, thereby establishing a clear confirmation mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic device sends no feedback information upon completing the shipping mode entry, then the system test machine defaults the device has entered the shipping mode, but this leads to devices that failed to enter the shipping mode being shipped by mistake
Solution Approach 1:
The patent implements a feedback mechanism where the electronic device actively sends a feedback instruction to the system test machine after entering the shipping mode. This feedback instruction confirms successful mode entry, allowing the system test machine to accurately verify the shipping mode status rather than relying on default assumptions. This resolves the contradiction by maintaining high productivity while significantly improving reliability through active confirmation.
2Device complexity
If the system test machine assumes shipping mode entry without closed-loop monitoring, then the monitoring process is simple and fast, but defective devices cannot be identified before shipping
Solution Approach 1:
The patent introduces a feedback instruction sent from the electronic device to the system test machine that confirms successful shipping mode entry. This creates a closed-loop monitoring system where the device actively reports its status. The feedback mechanism adds minimal complexity while dramatically improving reliability by enabling definitive verification of shipping mode entry before devices leave the factory.
3Reliability
If feedback information is sent to confirm shipping mode entry, then defective devices can be identified, but the communication process between device and host computer becomes more complex
Solution Approach 1:
The patent implements a dedicated feedback instruction that the electronic device sends to the host computer to confirm successful shipping mode entry. This single-purpose feedback mechanism provides clear confirmation without requiring complex communication protocols. The feedback instruction simplifies the confirmation process by establishing a direct, unambiguous communication channel for status verification.

AI summary
A method for setting a shipping mode of an electronic device. The method includes the following steps: receiving a shipping instruction sent by a host computer to enter the shipping mode; and sending a shipping-mode feedback instruction to the host computer, where the shipping-mode feedback instruction is a valid-response instruction for a successful entry into the shipping mode or an invalid-response instruction for a failed entry into the shipping mode. An electronic device and a computer readable storage medium are also provided in this application. The method for setting the shipping mode, the electronic device and the computer readable storage medium can accurately feed back whether the electronic device has successfully entered the shipping mode, to avoid a problem that the electronic device not really entering the shipping mode can leave the factory due to omission, improving users' experience.
