Solution Overview

Problem

Conventional tuning processes for devices like motors are time-consuming and resource-intensive, often requiring iterative trials to achieve performance thresholds, especially in robotic systems, where predetermined parameters may not satisfy performance criteria.

Innovation Solution

A live tuning system that enables continuous, interactive adjustment of motor parameters and tests without reinitiating the tuning process, allowing for periodic updates and automatic execution of tests and parameters based on user input and real-time results, reducing the need for iterative reinitialization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional iterative tuning processes are used to achieve performance thresholds, then device performance is improved, but tuning time and resource consumption increase significantly

Engineering Contradiction:

Improveperformance threshold satisfactionVSAvoidtuning time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The tuning process continues without interruption by executing multiple tests sequentially within a single tuning session. The system maintains continuous operation by automatically transitioning from one test to the next based on predefined criteria, eliminating the need to stop and reinitialize between tests.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system pre-defines multiple tests and their execution criteria before the tuning process begins. This preliminary configuration allows the tuning system to automatically determine when to proceed to the next test based on results from previous tests, enabling continuous operation without manual intervention.

Inventive Principle:

Principle #10Preliminary action

2Manufacturing precision

If multiple iterative trials are conducted to tune device parameters, then performance criteria are met, but user interactions and system reinitializations increase

Engineering Contradiction:

Improveparameter tuning precisionVSAvoiduser interaction frequency

Core Design Contradiction:

Manufacturing precisionVSEase of operation

Solution Approach 1:

The tuning system automatically evaluates test results and determines whether to proceed to the next test based on predefined criteria. This self-service capability eliminates the need for users to manually analyze results and initiate subsequent tests, reducing user interaction while maintaining precise parameter tuning.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback from each test result to automatically determine the next course of action. Based on whether performance thresholds are met or not met, the system automatically proceeds to alternative tests or adjusts parameters, eliminating the need for manual reinitialization and reducing user interaction.

Inventive Principle:

Principle #23Feedback

3Ease of manufacture

If predetermined parameters are used for device operation, then device setup is simplified, but performance thresholds may not be satisfied

Engineering Contradiction:

Improvedevice setup simplicityVSAvoidperformance threshold satisfaction

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The system automatically changes parameters based on test results by selecting alternative tests with different parameter sets. When predetermined parameters do not satisfy performance thresholds, the system transitions to tests that use modified parameters, thereby maintaining both ease of setup and performance satisfaction.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The tuning process is dynamic rather than static. The system adapts its test sequence and parameters based on real-time results from previous tests, allowing it to transition from predetermined parameters to adjusted parameters automatically, ensuring performance thresholds are met while maintaining operational simplicity.

Inventive Principle:

Principle #15Dynamics
