Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If human workers perform de-palletization operations, then flexibility and adaptability are maintained, but safety risks and resource intensity increase

Engineering Contradiction:
ImprovesafetyVSAvoidresource intensity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system enables autonomous package registration and handling through self-service mechanisms. The robotic arm automatically captures images, processes them through the detection pipeline, generates MVRs, and executes pickup operations without human intervention, thereby improving safety while maintaining operational efficiency

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces human manual operations with an automated robotic system that uses imaging devices, processing systems, and robotic arms. This substitution eliminates safety risks associated with human workers handling heavy or awkward packages while maintaining continuous operational capability

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

2Productivity

If the system operates autonomously without manual registration, then productivity increases, but measurement precision may deteriorate for unrecognized packages

Engineering Contradiction:
Improveautomation efficiencyVSAvoidphysical characteristics identification
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by capturing images of packages before handling operations. The imaging device records package appearance, and the processing system pre-processes these images through the detection pipeline to generate MVRs, ensuring accurate physical characteristic identification is completed before the robotic arm executes pickup operations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary detection pipeline that acts as a mediator between image capture and robotic execution. This pipeline includes processing systems that analyze images, generate MVRs, and translate visual data into actionable handling parameters, ensuring measurement precision is maintained throughout the autonomous operation

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If Minimum Viable Regions are generated for unrecognized packages, then handling accuracy improves, but device complexity increases

Engineering Contradiction:
Improvepackage handling accuracyVSAvoiddetection pipeline complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system segments the package handling process into distinct functional modules: an imaging device for image capture, a processing system for image analysis, a detection pipeline for MVR generation, and a robotic arm for execution. This segmentation allows each component to specialize in its function, improving handling accuracy while managing complexity through modular architecture

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detection pipeline is designed as a universal system that can process various package types and generate appropriate MVRs for different geometries and orientations. The processing system handles both recognized and unrecognized packages through the same pipeline, reducing overall device complexity while maintaining handling accuracy across diverse package configurations

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

AI summary

The present disclosure relates to methods and systems for generating a verified minimum viable range (MVR) of an object. An exposed outer corner and exposed edges of an object may be identified by processing one or more image data. An initial MVR may be generated by identifying opposing parallel edges opposing the exposed edges. The initial MVR may be adjusted, and the adjusted result may be tested to generate a verified MVR.
