Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional robot operation methods are used, then the robot can perform operations, but the instruction complexity and operational difficulty are high

Engineering Contradiction:
Improveinstruction simplicityVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a language model as an intermediary between the user and the robot control system. The language model converts natural language instructions into executable robot commands, eliminating the need for users to directly write complex programming code. This mediator handles the complexity transformation, allowing simple textual input to produce sophisticated robot operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical programming interfaces (buttons, dials, code editors) with a linguistic interface. Instead of manipulating physical controls or writing structured code, users simply type natural language descriptions of desired robot actions. The system translates these linguistic inputs into the appropriate control signals, substituting the mechanical interaction paradigm with a more intuitive linguistic one.

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

2Productivity

If traditional programming methods are used for robot control, then precise operations can be achieved, but the time and effort required for programming are significant

Engineering Contradiction:
Improveprogramming efficiencyVSAvoidprogramming time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The language model performs self-service by automatically generating the complete robot control program from a single natural language description. Instead of requiring programmers to manually write, debug, and optimize code line-by-line, the system autonomously translates the high-level intent into executable instructions, significantly reducing both programming time and human effort.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary analysis and planning of the robot operation sequence automatically. When receiving a natural language instruction, the language model pre-processes the request, determines the necessary action sequence, selects appropriate commands, and prepares the complete program before execution. This preliminary automated processing eliminates the time-consuming manual programming steps.

Inventive Principle:
Principle #10Preliminary action
