Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mobile communication devices lack an efficient method to quickly and automatically retrieve manufacturing and configuration information, especially when barcodes are not accessible or readable, leading to difficulties in troubleshooting and customer service processes.

Innovation Solution

A biographical digest system using a radio frequency identity (RFID) chip partitioned into static and dynamic portions, where inception information is stored in the static portion and current configuration information is stored in the dynamic portion, accessible via a biographical digest software layer that enables encryption and secure writing, allowing for easy scanning and updating of device information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If barcodes are used to store device information, then information can be stored on the device, but the information cannot be retrieved when barcodes are not accessible or readable

Engineering Contradiction:

Improveinformation retrieval reliabilityVSAvoidinformation access difficulty

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical/optical barcode system with an RFID chip-based electronic storage and retrieval system. The RFID chip stores device information electronically and allows wireless automated retrieval without requiring physical scanning or line-of-sight access, thereby eliminating the limitations of barcode accessibility while maintaining information storage capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If device information is stored in accessible locations, then information can be easily retrieved, but security and protection of sensitive information are compromised

Engineering Contradiction:

Improveinformation retrieval easeVSAvoidinformation security risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary layer between the RFID chip storage and the retrieval process. The system requires authentication and uses controlled access protocols to retrieve information from the RFID chip, allowing easy automated retrieval while maintaining security through the intermediary authentication mechanism that prevents unauthorized access to sensitive device information.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If manual entry of device information is used, then information can be recorded, but customer service efficiency and troubleshooting speed are reduced

Engineering Contradiction:

Improvecustomer service efficiencyVSAvoidinformation retrieval time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent implements a self-service system where the RFID chip automatically provides device information when queried by authorized systems. The chip stores inception information, current configuration, and status data that can be rapidly retrieved without manual data entry, enabling customer service representatives to quickly obtain device details for troubleshooting and service operations, thereby significantly improving productivity and reducing time loss.

Inventive Principle:

Principle #25Self-service

Data Source

PatentUS9171243B1System for managing a digest of biographical information stored in a radio frequency identity chip coupled to a mobile communication device

Publication Date: 2015.10.27 T MOBILE INNOVATIONS LLC

AI summary

A method of maintaining a biographical digest of information stored in a radio frequency identity chip communicatively coupled to a motherboard of a mobile communication device. The method comprises determining and writing inception information to the radio frequency identity chip once and preventing later modification of the inception information by a biographical digest software layer stored in a memory of the mobile communication device and executed by a processor of the device. The method further comprises determining and writing current information to the radio frequency identity chip by the biographical digest software layer in response to triggering events.
