Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If handheld barcode scanners are used for medication tracking, then medication identification and inventory management are facilitated, but hands are occupied which impedes healthcare workflow processes and limits user mobility

Engineering Contradiction:
Improvemedication tracking efficiencyVSAvoiduser mobility and workflow efficiency
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical handheld barcode scanner with an augmented reality glasses system that uses optical sensors, cameras, and image recognition algorithms to automatically identify medications. The system captures images of medication containers, analyzes them through computer vision, and updates inventory automatically without requiring physical contact or manual scanning operations.

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

Solution Approach 2:

The augmented reality system performs self-service by automatically detecting medications through visual recognition, determining user actions through sensor data analysis, and updating inventory records without requiring manual intervention. The system autonomously tracks medication movements and maintains inventory accuracy while leaving hands free for other tasks.

Inventive Principle:
Principle #25Self-service

2Productivity

If paper documentation is used for inventory updates, then medication tracking is possible, but transcription errors, document misplacement, and medication diversion may occur

Engineering Contradiction:
Improveinventory update capabilityVSAvoidaccuracy of inventory data
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces manual paper documentation with an automated electronic system that uses image recognition, sensor data processing, and digital database storage. The system captures images of medications, automatically identifies them through computer vision algorithms, and updates inventory records electronically, eliminating the need for manual transcription and reducing human error.

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

Solution Approach 2:

The system incorporates feedback mechanisms where sensors continuously monitor user actions and medication locations, the augmented reality display provides real-time visual confirmation of identified medications, and the system automatically verifies and updates inventory records. This multi-layer feedback loop ensures accuracy and allows for immediate correction of any potential errors.

Inventive Principle:
Principle #23Feedback

3Productivity

If handheld devices are tethered to a specific location or device, then medication tracking can be performed, but deployment flexibility and user mobility are limited

Engineering Contradiction:
Improvemedication tracking capabilityVSAvoiddeployment flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The augmented reality glasses system serves multiple functions including medication identification, inventory tracking, user action detection, and communication with healthcare systems. The single wearable device consolidates what would traditionally require multiple separate tools and systems, providing universal functionality across different locations and scenarios without requiring tethering to specific equipment.

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