Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional robot control methods are used, then the robot can operate in structured environments, but it fails to safely navigate dynamic environments with humans and obstacles

Engineering Contradiction:
Improvesafe operation in dynamic environmentVSAvoidability to handle unstructured dynamic environments
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces large language models as an intermediary between sensor data and robot control decisions. The LLM processes textual state descriptions of the environment and generates predictions about agent behavior, serving as a mediator that bridges traditional perception systems and control systems, enabling safe operation in dynamic environments

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical control algorithms with language model-based predictive systems. Instead of using conventional motion planning and collision avoidance algorithms, the system uses LLMs to predict future states and generate task plans, substituting mechanical control approaches with cognitive-like processing

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

2Measurement precision

If complex control algorithms are used to predict agent behavior, then navigation accuracy improves, but computational complexity and processing time increase

Engineering Contradiction:
Improveprediction accuracy of agent behaviorVSAvoidcomputational complexity of control system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses large language models trained on extensive textual data about human behavior and environments. The LLMs copy patterns and knowledge from training data to make predictions about agent behavior, allowing the system to achieve high prediction accuracy without implementing complex real-time simulation or reasoning algorithms

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent performs preliminary training of large language models offline using extensive datasets. This preliminary action transfers knowledge to the model before deployment, enabling the robot to make accurate predictions during operation without requiring complex real-time computations, thus reducing operational computational complexity

Inventive Principle:
Principle #10Preliminary action

3Speed

If real-time processing of sensor data is implemented, then responsive control is achieved, but data processing completeness and accuracy decrease

Engineering Contradiction:
Improveresponse time of robot controlVSAvoidcompleteness of environmental state description
Core Design Contradiction:
SpeedVSLoss of information

Solution Approach 1:

The patent introduces textual state descriptions as an intermediary representation that captures essential environmental information in a compact format. The LLM processes these textual descriptions rather than raw sensor data, maintaining information completeness while enabling faster processing through natural language understanding

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms sensor data into textual parameters that describe the state of the environment and agents. This parameter transformation changes the data representation from continuous sensor readings to discrete textual descriptions, enabling efficient processing while preserving critical information about the environment

Inventive Principle:
Principle #35Parameter changes

AI summary

A method for controlling a robot apparatus. The method includes collecting state information about an agent located in an environment of the robot apparatus, converting the state information about the agent into a textual state description, feeding the textual state description to a large language model for generating a prediction of a behavior of the agent, a future state of the agent and/or the environment, generating a task plan for the robot apparatus taking into account the prediction, and controlling the robot apparatus according to the task plan.
