Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional robot modeling techniques focusing on kinematics and dynamics are used, then robot control performance is improved, but environmental awareness and navigation capability deteriorate

Engineering Contradiction:
Improverobot control performanceVSAvoidenvironmental awareness
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent merges traditional robot modeling (kinematics, dynamics) with environmental modeling (object detection, 3D reconstruction) into a unified framework. The robot model and environment model are integrated to enable comprehensive simulation and control that accounts for both robot mechanics and environmental factors.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an environment model as an intermediary between the robot controller and the physical environment. This model acts as a mediator that processes sensory information about obstacles and terrain, translating it into constraints and parameters that affect robot planning and control.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If environmental factors like obstacles and terrain variations are incorporated into robot modeling, then navigation capability is improved, but computational complexity increases

Engineering Contradiction:
Improvenavigation capabilityVSAvoidcomputational complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the complex task of environmental modeling into distinct components: object detection using sensors, classification of objects, construction of 3D environment models, and integration with robot models. This segmentation allows each component to be processed independently and efficiently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates simplified virtual copies of the physical environment through 3D modeling and simulation. Instead of processing all raw sensory data in real-time, the system constructs representative models that capture essential environmental features, reducing computational burden while maintaining navigation accuracy.

Inventive Principle:
Principle #26Copying

3Productivity

If real-time 3D environment construction is implemented, then operational efficiency is improved, but processing time and computational resources increase

Engineering Contradiction:
Improveoperational efficiencyVSAvoidprocessing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent performs preliminary environment modeling and simulation before actual robot execution. By constructing 3D models and running simulations in advance, the system identifies potential issues and optimizes paths beforehand, reducing the need for complex real-time processing during actual operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous environment monitoring and model updating, where the 3D environment model is continuously refined as new sensory information becomes available. This allows the system to maintain an accurate environmental representation without requiring complete re-processing, improving efficiency over time.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A method for displaying an operating environment of a robot. The method includes determining an object type of each of one or more objects in the operating environment of the robot based on sensory information acquired by the robot; constructing a three-dimensional (3D) virtual environment of the operating environment based at least in part on the object type of each of the one or more objects; and displaying the 3D virtual environment of the operating environment via a display interface.
