Solution Overview

Problem

Existing carrier package scanning devices require tedious manual user input, leading to inaccuracies and negatively impacting the user experience, while location-sensing technologies like GPS struggle to accurately detect assets inside logistics vehicles due to signal interference.

Innovation Solution

Implementing a wearable RFID reader device that automatically reads asset tags, coupled with internal reader devices and reference tags within logistics vehicles, to determine asset placement and provide real-time guidance, reducing manual input and enhancing detection accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual scanning and triggering mechanisms are used in carrier package scanning devices, then device functionality is provided, but user experience deteriorates due to tedious manual input and accuracy decreases

Engineering Contradiction:
Improveuser experienceVSAvoiddetection accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The wearable reader device automatically performs scanning operations without requiring manual triggering. The device autonomously reads asset tags as the user moves through the logistics facility, eliminating the need for manual button presses or activation while maintaining continuous detection capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical triggering mechanisms with automated electronic detection systems. The wearable device uses automatic RFID or optical scanning technology to read asset tags without mechanical interaction, thereby improving both ease of operation and detection accuracy.

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

2Measurement precision

If GPS location-sensing technology is used to detect assets inside logistics vehicles, then location tracking is provided, but detection accuracy deteriorates due to signal interference

Engineering Contradiction:
Improvedetection accuracyVSAvoidsignal interference
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces intermediary reader devices positioned inside logistics vehicles that act as mediators between the asset tags and the central tracking system. These intermediaries read asset tags directly using RFID or optical technology, avoiding GPS signal interference while maintaining accurate location and verification capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of relying on GPS signals that penetrate through vehicle structures, the system uses local reader devices that create copies of asset tag data within the vehicle environment. This copying approach bypasses signal interference issues by performing readings in the immediate vicinity of the assets.

Inventive Principle:
Principle #26Copying

3Ease of operation

If automated wearable reader devices are implemented, then ease of operation improves by eliminating manual input, but device complexity increases

Engineering Contradiction:
Improvemanual input requirementVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wearable reader device is designed as a multi-functional unit that combines scanning, data processing, and communication capabilities in a single device. This universal approach consolidates multiple functions into one wearable unit, improving ease of operation while managing complexity through integration rather than proliferation of separate devices.

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

Solution Approach 2:

The system implements a nested architecture where wearable reader devices contain embedded processing units and communication modules. The wearable device nests within a larger network infrastructure, with each layer handling specific functions, thereby distributing complexity across hierarchical levels rather than concentrating it in single devices.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Measurement precision

If multiple reader devices and reference tags are deployed throughout logistics vehicles, then detection accuracy improves, but computing resource consumption increases

Engineering Contradiction:
Improveasset location detection accuracyVSAvoidcomputing resource consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system activates reader devices and reference tags selectively based on operational needs rather than continuous operation. Readers are activated when vehicles are being loaded or unloaded, and reference tags are read only when relevant to current logistics operations, reducing overall computing resource consumption while maintaining detection accuracy when needed.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

Reference tags are pre-positioned in strategic locations within logistics vehicles before operations begin. This preliminary placement allows reader devices to efficiently verify asset locations without requiring continuous scanning or complex real-time calculations, thereby reducing computing resource consumption while maintaining high detection accuracy.

Inventive Principle:
Principle #10Preliminary action

AI summary

In various embodiments, a first indication that a first reader device has read data of a first tag coupled to a first asset is received. The first reader device is included in an article worn by a user. Subsequent to the receiving of the first indication, a second indication that at least one of: a second reader device has read the data of the first tag, or the first reader device has read data of a second tag is received. The second reader device and the second tag are located in a first logistics vehicle. Based at least in part on the receiving of the first indication and the second indication, it is determined that the user has transported the first asset to the first logistics vehicle. In response to the determining, a notification indicating whether the first asset has been transported to a correctly assigned logistics vehicle is transmitted to the first reader device or a third device associated with the user.
