Solution Overview

Problem

In the telecommunications industry, tracking inventory items such as mobile devices and SIM cards is complex due to the need for separate SKUs, leading to inefficiencies in managing and monitoring their status throughout their life cycle.

Innovation Solution

Assigning a single SKU to each inventory item, including devices and SIMs, allows for precise tracking and monitoring of their status, eliminating the need for separate SKUs and facilitating efficient inventory management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If separate SKUs are used for tracking different inventory items (devices and SIMs), then each item can be individually identified, but the system complexity and overhead increase significantly

Engineering Contradiction:

Improvetracking accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple SKUs (device SKU and SIM SKU) into a single unified SKU that can represent both the device and SIM card together. This merging approach maintains the ability to track both items individually while reducing system complexity by eliminating the need for separate tracking mechanisms.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The unified SKU serves multiple functions: it can represent a device alone, a SIM card alone, or both together as a bundle. This multi-functionality allows the system to handle various inventory scenarios (single device, single SIM, device-SIM bundle) with a single tracking mechanism, reducing overhead while maintaining precision.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Loss of information

If separate SKUs are maintained for devices and SIMs, then inventory status can be monitored, but the overhead and difficulty in managing multiple SKUs increases

Engineering Contradiction:

Improveinventory information completenessVSAvoidinventory management ease

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

By merging device and SIM tracking into a single SKU, the system maintains complete inventory information while simplifying management operations. The unified SKU can still capture all necessary details about both the device and SIM card, but eliminates the operational burden of managing separate SKUs for each item type.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If multiple SKUs are used to track inventory items through their life cycle, then status changes can be monitored, but the time and resources required for tracking increase

Engineering Contradiction:

Improvetracking reliabilityVSAvoidtracking time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The unified SKU approach combines tracking operations for devices and SIMs into a single process, maintaining reliable tracking of status changes while reducing the time and resources required. Instead of updating multiple separate SKUs when a device or SIM status changes, the system updates a single unified SKU, thereby maintaining reliability while reducing tracking time.

Inventive Principle:

Principle #5Merging (Combining)

4Measurement precision

If separate tracking systems are used for different inventory items, then each item's status can be monitored, but the overall inventory management efficiency decreases

Engineering Contradiction:

Improvestatus monitoring accuracyVSAvoidinventory management efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The patent merges separate tracking systems into a unified SKU-based system that maintains accurate status monitoring for all inventory items while improving overall management efficiency. By consolidating tracking operations, the system reduces redundancy and streamlines processes, thereby maintaining precision while enhancing productivity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method for tracing an inventory item from an inventory is provided. In one example, the method includes: obtaining a single SKU and assigning the single SKU to an inventory item of an inventory; generating a single SKU profile for the inventory item according to the single SKU and storing the single SKU profile in an inventory SKU data model, the single SKU profile including a number of the single SKU and an inventory location of the single SKU; generating an inventory record according to the single SKU and storing the inventory record in the inventory SKU data model; identifying the inventory item according to the number and location of the single SKU, based on an instruction for order fulfillment; and tracking the inventory item according to the single SKU to determine an inventory status change thereof and recording the inventory status change in the inventory record.
