Solution Overview

Problem

Existing dedusting systems face challenges in flexible and efficient control of fan and filter operations due to the need for complex signal connections between multiple machines and control modules, leading to increased installation work and potential for incomplete or mismatched control configurations.

Innovation Solution

A modular control system using wireless signal transmission between master and slave modules, allowing for flexible assembly and operation of dedusting systems with modules such as filter control, fan control, damper control, residual dust control, and spark extinguishing control, eliminating the need for extensive electrical connections and enabling various system configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If signal lines are laid along existing cable ducts from each machine to the system control, then signal transmission is achieved, but installation work and time are significantly increased

Engineering Contradiction:
Improvesignal transmissionVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical/electrical signal transmission system (cable ducts and signal lines) with a wireless communication system. Each machine has a wireless transmitter that communicates with the system control unit via wireless signals, eliminating the need for physical cable installation while maintaining reliable signal transmission.

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

2Adaptability or versatility

If control modules are permanently installed in electrical control cabinets, then control functionality is provided, but installation complexity and work are increased

Engineering Contradiction:
Improvecontrol functionalityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system control unit is designed as a universal device that can perform multiple control functions (filter control, fan control, and potentially other control modules) through software configuration rather than requiring separate dedicated control modules for each function, thereby reducing installation complexity while maintaining full control functionality.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a wireless communication system as an intermediary between the machines and the system control unit, replacing the need for complex electrical connections and permanent installation in control cabinets. The wireless transmitters and receivers act as intermediaries that simplify the overall system architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple control modules (filter control, fan control) are used from different suppliers, then specific control functions are achieved, but system complexity and configuration difficulty are increased

Engineering Contradiction:
Improvecontrol functionsVSAvoidsystem configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines filter control and fan control functions into a single integrated system control unit. This unified approach eliminates the complexity of coordinating multiple separate control modules from different suppliers, while still providing all necessary control functions through a single standardized interface and control logic.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The modular construction kit has a filter control-module (1) and a fan control-module (2), of which one module, particularly the filter control-module acts as a master-module and has a signal generator. The modules are arranged in separate control housings. Each control housing has a connector socket for a signal transmission, particularly a combined signal- or current transmission. The construction kit also has a combination cable (5) for simultaneous signal- and current transmission. Independent claims are also included for the following: (1) a method for attaching an exhaust system controller; and (2) a system controller for a dust removal system with an air filter.
