Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional RFID tags are used for tracking inventory, then tracking capability is provided, but cost and resource consumption increase

Engineering Contradiction:

Improvetracking capabilityVSAvoidnumber of RFID tags

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges the RFID tracking function with the glove itself, making the glove both the protective equipment and the tracking device. The resistive fabric sensors and RFID reader are integrated into the glove structure, eliminating the need for separate RFID tags on inventory items. This consolidation reduces the total number of tracking components while maintaining tracking capability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The glove serves multiple functions simultaneously: it provides tactile feedback for inventory handling, tracks inventory status through resistive fabric sensors, identifies the user through fingerprint scanning, and communicates with the inventory management system. This multi-functionality eliminates the need for separate tracking tags and reduces overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple RFID tags are deployed for comprehensive tracking, then tracking accuracy improves, but system complexity and cost increase

Engineering Contradiction:

Improvetracking accuracyVSAvoidRFID infrastructure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The glove performs self-tracking by using its own resistive fabric sensors to detect inventory handling actions and its integrated RFID reader to read tags on inventory items. The system automatically classifies actions, identifies users through fingerprint scanning, and communicates status without requiring external tracking devices or complex infrastructure. This self-service approach simplifies the overall system while maintaining accurate tracking.

Inventive Principle:

Principle #25Self-service

3Productivity

If RFID readers and sensors are integrated into gloves, then real-time tracking is enabled, but power consumption increases

Engineering Contradiction:

Improvereal-time trackingVSAvoidpower consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The RFID reader and sensors in the glove operate periodically rather than continuously, activating only when needed for inventory handling actions. The resistive fabric sensors continuously monitor for deformation but only trigger full RFID reading sequences when specific handling patterns are detected. This periodic operation maintains real-time tracking capability while significantly reducing average power consumption.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The glove's fingerprint scanner and resistive fabric sensors automatically detect user identity and tracking needs without requiring external power sources or continuous active monitoring. The system leverages the natural physical interactions between the user and inventory items to trigger tracking functions, eliminating the need for constant power-intensive operations while maintaining productivity.

Inventive Principle:

Principle #25Self-service
