Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices with non-removable batteries pose challenges in quickly and automatically accessing manufacturing and configuration information, as barcodes may be smudged, torn, or aesthetically unacceptable, and manual entry can be slow and error-prone, especially when scanning multiple devices.
Innovation Solution
Incorporating a radio frequency identity (RFID) chip connected to the communication bus, which stores manufacturing and configuration information and can be read/write-enabled via a near field communication (NFC) scanner, even when the device is turned off or without a battery, allowing for quick and accurate data retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If barcodes are affixed to the device for storing manufacturing and configuration information, then information storage is achieved, but the barcodes may be smudged, torn, or aesthetically unacceptable
Solution Approach 1:
The patent replaces physical barcodes with an RFID chip that stores device information. The RFID chip creates a digital copy of the device's identification and configuration data, eliminating the need for physical barcodes that can be smudged or torn. This resolves the contradiction by maintaining information storage reliability while eliminating the harmful effects of barcode degradation.
Solution Approach 2:
The patent substitutes the mechanical barcode system with an electronic RFID chip system. Instead of relying on physical printed barcodes that are susceptible to damage, the invention uses an electronic storage medium (RFID chip) that can be read wirelessly, eliminating the mechanical vulnerability of barcodes while maintaining reliable information storage.
2Ease of operation
If manual entry of device identification information is used, then information can be accessed, but the process is slow and error-prone
Solution Approach 1:
The patent replaces manual entry operations with automated RFID reading. Service personnel use an RFID reader to automatically retrieve device information from the RFID chip, eliminating the need for manual typing or data entry. This substitution dramatically increases service speed and eliminates human errors associated with manual entry.
Solution Approach 2:
The RFID chip enables the device to provide its own identification information automatically when queried by an RFID reader. The device essentially serves itself by storing and providing its configuration and manufacturing data without requiring manual input from service personnel, thereby increasing productivity and reducing errors.
3Use of energy by moving object
If RFID chip operates only when battery is available, then power consumption is managed, but the chip cannot be read when device is turned off or without battery
Solution Approach 1:
The RFID chip is designed with dual functionality: it can operate in powered mode when the device battery is available, and in passive mode when powered by the RFID reader's electromagnetic field. This multi-functionality allows the chip to be read in both powered and unpowered states, resolving the contradiction between power management and information accessibility.
Solution Approach 2:
The RFID chip dynamically adapts its operating mode based on power availability. When battery power is present, the chip uses active mode with lower read power requirements. When battery power is absent or the device is off, the chip switches to passive mode, harvesting power from the RFID reader's electromagnetic field. This dynamic adaptation ensures information accessibility across all device states while managing power consumption efficiently.
