Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional Bluetooth tracking devices are used, then item tracking is possible, but cost increases and privacy concerns arise

Engineering Contradiction:
Improveitem tracking capabilityVSAvoidprivacy concerns and cost
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses visual copying through camera images to track items instead of physical Bluetooth trackers. The machine learning model creates visual representations and comparisons of items from camera feeds, allowing tracking without attaching physical devices to items, thereby eliminating privacy concerns and costs associated with Bluetooth trackers.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical Bluetooth tracking system with an optical-computational system using cameras and machine learning. Instead of radio frequency communication and physical trackers, the system uses visual capture and AI-based identification to achieve item tracking, eliminating the need for additional hardware on items.

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

2Reliability

If GPS-based solutions are deployed, then location tracking is achieved, but applicability is limited and cost increases

Engineering Contradiction:
Improvelocation tracking accuracyVSAvoidapplicability to indoor premises
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces GPS satellite-based positioning with an optical recognition system using cameras and machine learning. This substitution enables tracking to work indoors where GPS signals are unavailable, significantly improving adaptability to indoor premises while maintaining location tracking accuracy through visual identification.

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

Solution Approach 2:

The system uses existing IoT cameras for multiple purposes including security monitoring and item search, making the solution universally applicable across different settings without requiring specialized tracking hardware. The machine learning model can identify various types of items regardless of location, enhancing versatility.

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

3Ease of manufacture

If existing IoT cameras are utilized for item search, then cost is reduced, but item identification accuracy must be improved

Engineering Contradiction:
Improvesystem cost reductionVSAvoiditem identification accuracy
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent changes the parameters of existing cameras by using them in specific configurations optimized for item search, such as strategic placement and angle adjustment. The machine learning model processes images from these cameras with specialized algorithms that enhance identification accuracy, allowing standard cameras to achieve precision comparable to specialized tracking devices.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system enables existing cameras to serve dual purposes: their original security function and new item search function. By leveraging the cameras' existing capabilities and adding software-based item identification through machine learning, the system achieves accurate item tracking without requiring additional hardware investment.

Inventive Principle:
Principle #25Self-service

4Measurement precision

If machine learning models are trained with user data, then item recognition improves, but processing time increases

Engineering Contradiction:
Improveitem recognition accuracyVSAvoidmodel training time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-training machine learning models with common item types before actual use. This allows the models to have baseline recognition capabilities immediately, while user-specific training can be performed incrementally in the background without significantly impacting real-time search performance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where user corrections and confirmations during item searches are used to continuously refine and retrain the machine learning models. This feedback loop improves recognition accuracy over time while the training occurs in manageable increments that minimize disruption to system operation.

Inventive Principle:
Principle #23Feedback
