Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid movement systems, such as HVAC and aquatic systems, require specialized equipment in laboratories to determine efficiency, which is inconvenient and costly, especially when efficiency changes due to filter clogging or configuration alterations.
Innovation Solution
A motor controller coupled with an efficiency indicator device and a motor, which determines fluid flow and power usage amounts over a predefined period, generates and transmits an efficiency report for real-time presentation, allowing for on-site assessment of system efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specialized equipment in a laboratory is used to determine efficiency, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The fluid movement system performs its own efficiency monitoring using the motor controller's built-in processing capabilities. The motor controller determines fluid flow amounts and power usage amounts, generates efficiency reports, and transmits them to efficiency indicator devices without requiring external specialized equipment, enabling the system to serve its own monitoring needs
Solution Approach 2:
The motor controller is designed to perform multiple functions: it controls the motor operation, determines fluid flow amounts, determines power usage amounts, generates efficiency reports, and transmits data to efficiency indicator devices. This multi-functional approach eliminates the need for separate specialized measurement equipment
2Measurement precision
If specialized laboratory equipment is used for efficiency determination, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically monitors its own efficiency in the field using the motor controller's integrated capabilities, eliminating the need to transport systems to laboratories or use complex specialized equipment, thereby enabling easy on-site monitoring by technicians or manufacturers
Solution Approach 2:
The patent replaces mechanical/specialized measurement equipment with an electronic control system. The motor controller uses electronic sensing and processing to determine fluid flow and power usage, substituting physical measurement devices with electronic-based determination methods that are easier to operate in the field
3Measurement precision
If traditional efficiency monitoring methods are used, then measurement precision is maintained, but loss of time increases
Solution Approach 1:
The motor controller continuously determines fluid flow amounts and power usage amounts during normal system operation and continuously generates efficiency reports. This continuous monitoring eliminates the need to stop the system for efficiency assessments, maintaining uninterrupted operation while providing ongoing efficiency data
Solution Approach 2:
The system performs its own efficiency monitoring without requiring external laboratory equipment or technician intervention for measurements. The motor controller autonomously determines efficiency parameters and generates reports, eliminating time-consuming manual measurement processes
