Solution Overview

Problem

The existing methods for locating specific baggage in aircraft cargo bays are time-consuming and inefficient, especially in cramped, poorly lit environments, leading to potential departure and arrival delays due to the need for manual searching and the challenges of identifying items in dark conditions.

Innovation Solution

A system comprising a passive or active RFID tag with an integrated electroluminescent layer that glows when interrogated, allowing for quick identification of tagged items in dark environments, combined with an RFID reader that uses unique tag identifiers to determine the location of the items within the cargo bay.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual searching methods are used to locate baggage in cargo bays, then personnel can identify items by physically examining tags, but the process becomes time-consuming and leads to departure delays

Engineering Contradiction:
Improvebaggage identification accuracyVSAvoidtime to locate baggage
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical manual searching process with an automated RFID detection system. The RFID reader automatically detects and locates baggage tags using electromagnetic fields, eliminating the need for personnel to physically climb into cargo bays and manually examine each tag, thus resolving the contradiction between identification accuracy and time consumption

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces RFID tags as intermediaries attached to baggage and RFID readers as intermediary devices for detection. These intermediaries enable automatic identification and location of baggage without direct human intervention in the cargo bay, significantly reducing search time while maintaining accurate identification

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If personnel climb into cargo bays to search for baggage, then they can access and examine items, but the cramped and poorly lit environment makes the search difficult and time-consuming

Engineering Contradiction:
Improveease of baggage searchVSAvoidtime required for search
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent replaces the mechanical process of personnel physically navigating cramped cargo bays with an automated RFID detection system. The RFID reader can be operated from outside the cargo bay, eliminating the need for personnel to enter difficult-to-access spaces, thereby improving ease of operation and reducing search time

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The RFID tags on baggage perform the identification function automatically when interrogated by the RFID reader. The system serves itself by enabling automatic detection and location of baggage without requiring human personnel to physically search through the cargo bay, improving operational ease and efficiency

Inventive Principle:
Principle #25Self-service

3Productivity

If traditional manual methods are used to locate baggage, then no additional equipment is needed, but the aircraft must remain on the tarmac longer causing costly delays

Engineering Contradiction:
Improveturnaround efficiencyVSAvoidcomplexity of locating system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The RFID reader device serves multiple functions: it can read RFID tags on baggage, determine their locations within the cargo bay, and provide this information to personnel. This multi-functional approach improves turnaround efficiency without requiring multiple separate systems, thus managing device complexity while enhancing productivity

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The RFID system acts as an intermediary layer between the baggage and the personnel searching for it. By introducing this intermediate detection system, the patent enables rapid identification of baggage locations, significantly improving turnaround efficiency while the added complexity is offset by the elimination of manual search processes

Inventive Principle:
Principle #24Intermediary (Mediator)
