Direct Serial Mobile Diagnostics Without App Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device recycling processes face inefficiencies in assessing device functionality and securely erasing data without installing apps, especially for devices with non-functional displays or discharged batteries, and retail settings lack efficient diagnostic and provisioning hardware.
Innovation Solution
A system that establishes a direct serial connection with mobile devices through USB or RS-232 protocols, adjusting electrical performance via resistance in the cable to identify and provision devices without app installation, enabling diagnostics and erasure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional app installation method is used for device diagnostics and erasure, then device functionality can be assessed, but the process is time-consuming and may not be possible for devices with non-functional displays or discharged batteries
Solution Approach 1:
The patent introduces a serial connection interface as an intermediary between the diagnostic system and the mobile device. This intermediary allows communication and device control through hardware-level access points (USB or Lightning ports) that do not require the device display or touchscreen to be functional. The serial connection enables the system to send commands and receive data directly from device components, bypassing the need for user interaction through the display interface.
Solution Approach 2:
The patent replaces the mechanical interaction system (touchscreen, display, button presses) with an electrical communication system (serial protocol over USB/Lightning connection). Instead of requiring mechanical user actions to navigate menus and confirm operations, the system uses electrical signals to directly communicate with device hardware components, enabling diagnostics and erasure operations on devices with non-functional displays.
2Productivity
If devices with discharged batteries are to be processed, then complete device assessment can be achieved, but requiring battery charge process first is time-consuming
Solution Approach 1:
The patent performs preliminary device identification and basic diagnostics through the serial connection before requiring full device operation. The system can identify device type, model, and basic status through hardware-level communication even when the battery is discharged and the device cannot fully boot. This preliminary action allows the system to prepare appropriate diagnostic procedures and power requirements in advance, reducing the need for lengthy charging cycles before assessment can begin.
3Adaptability or versatility
If retail settings use existing test systems, then mobile device diagnostics can be performed, but additional expensive hardware is required at each location
Solution Approach 1:
The patent creates a universal diagnostic interface that can work with multiple types of mobile devices through a single serial connection standard. The system uses standard USB or Lightning connectors that are universally present on modern mobile devices, eliminating the need for device-specific test hardware. The serial communication protocol provides a universal language for interacting with different device types, allowing the same diagnostic equipment to adapt to various devices without additional hardware configurations.

AI summary
There are provided systems and methods for mobile device diagnostics and provisioning, whereby connections are effectuated to communicate directly with hardware of mobile devices to perform diagnostics and other functions such as device erasure without the need to first install an app on the mobile device. In this manner, information such as detailed product identification, vendor identification, and diagnostic information may be quickly obtained from the mobile device, and diagnostics and erasure undertaken to return a previously owned device into the stream of commerce in an efficient manner.
