Motor Control Device Customization via Buffer Memory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial motor control devices face challenges in allowing users to easily modify system software parameters when load changes occur, as existing customization methods require technical expertise and risk erroneous motor operations, and may lead to leakage of manufacturer's knowledge.
Innovation Solution
A motor control device with a customization module and user module configuration, utilizing a buffer memory for data exchange, allowing users to modify specific functions without direct access to system software, thereby reducing the risk of erroneous operations and maintaining safety and expertise protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are allowed to directly modify system software parameters, then customization flexibility is improved, but system safety and reliability deteriorate due to risk of erroneous operations
Solution Approach 1:
The patent introduces a parameter setting unit that serves as an intermediary between the user and the system software parameters. This unit provides a controlled interface where users can input parameter values, which are then validated and processed through the customization module before being applied to the system. This intermediary structure allows customization while maintaining safety by preventing direct unauthorized modification of critical parameters.
Solution Approach 2:
The patent segments the parameter modification function into distinct modules: a parameter setting unit for user input, a customization module for processing and validation, and the system software for execution. This segmentation isolates the customization functionality from the core system software, allowing users to modify parameters through a controlled pathway while preserving the integrity and safety of the overall system.
2Adaptability or versatility
If users can directly access and modify system software, then customization capability is improved, but manufacturer knowledge protection deteriorates
Solution Approach 1:
The customization module acts as an intermediary layer between the user interface and the system software. It processes parameter values through validation rules and customization logic that are implemented by the manufacturer, allowing users to customize functionality while the manufacturer retains control over the underlying algorithms and proprietary knowledge embedded in the customization module.
Solution Approach 2:
The patent implements a parameter setting interface that copies or replicates the essential customization functionality needed by users without exposing the actual system software source code or proprietary algorithms. Users work with parameter values and configuration settings that are copies or abstractions of the underlying system, enabling customization while protecting manufacturer intellectual property.
3Adaptability or versatility
If comprehensive customization options are provided, then user needs adaptation is improved, but device complexity increases
Solution Approach 1:
The patent divides the customization functionality into a modular parameter setting unit and customization module structure. Each module handles specific aspects of parameter configuration, allowing comprehensive customization options to be organized in a structured, manageable way. This segmentation reduces perceived complexity by presenting users with organized, step-by-step configuration options rather than overwhelming them with all parameters at once.
Solution Approach 2:
The parameter setting unit provides users with self-service capabilities to configure system parameters according to their specific needs. The system automatically processes these configurations through the customization module, applying validation and processing without requiring users to understand the underlying complex software architecture. This self-service approach simplifies the user experience while maintaining comprehensive adaptability.
