Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoke and dust treatment equipment for welding is not effectively integrated, flexible, or efficient, leading to inadequate handling of toxic fumes and waste, posing health risks and resource inefficiencies in industrial settings.
Innovation Solution
A smoke and dust treatment apparatus combining a polishing and dust extraction module with a smoke and dust purification module, featuring a double-layer dust extraction cover, air guide hoses, and a mechanical arm for integrated grinding, welding, and dust collection, along with a purification system including a residue collection chamber and smoke purification chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent smoke purifier and electric industrial brush are used separately, then purification and polishing functions are achieved, but operational flexibility is reduced and resource occupation increases
Solution Approach 1:
The patent combines the smoke purifier and electric industrial brush into a single integrated apparatus. The brush assembly includes both the polishing brush and smoke collection components merged together, allowing simultaneous polishing and smoke purification functions. This eliminates the need for separate independent devices and operators, directly resolving the contradiction by maintaining purification effectiveness while significantly improving operational flexibility and reducing resource occupation.
Solution Approach 2:
The integrated apparatus performs multiple functions simultaneously: the electric industrial brush polishes the workpiece while the smoke purifier collects and treats welding fumes. The single device serves as both a polishing tool and a smoke treatment system, enabling one operator to perform tasks that previously required separate equipment and operators, thus resolving the flexibility and resource occupation issues.
2Productivity
If integrated design is implemented, then operational efficiency and space utilization improve, but device complexity increases
Solution Approach 1:
The integrated apparatus is divided into distinct functional modules: the electric industrial brush module for polishing, the smoke collection module with suction nozzles, the smoke purifier module with filtration system, and the drive mechanism. Each module is designed independently but integrated into a unified structure, allowing for easier manufacturing, assembly, and maintenance while achieving high operational efficiency through coordinated operation of all modules.
3Volume of moving object
If miniaturization is achieved, then space requirements are reduced and promotion feasibility improves, but manufacturing precision requirements increase
Solution Approach 1:
The design employs a nested structure where the smoke collection nozzles and brush components are arranged concentrically around the central drive shaft. The smoke purifier housing encloses the filtration system, which in turn contains the collection chambers. This nested arrangement minimizes the overall apparatus volume while maintaining proper spacing and alignment, reducing the need for extremely high manufacturing precision compared to distributed layouts.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus achieves miniaturization, automation, and enhanced safety by integrating dust collection and smoke purification processes, effectively recycling residues and purifying harmful gases, while improving operational safety and reducing resource waste.
Implementation Method 1
an electromagnetic chuck is arranged at the bottom end of the residual collection chamber, and a magnetic residue box is arranged on the electromagnetic chuck
Implementation Method 2
an exhaust fan is arranged below the smoke purification chamber and is used to provide a negative pressure for delivering smoke and dust into the smoke and dust purification module from the polishing and dust extraction module
Implementation Method 3
the industrial brush is disposed in the protective cover and can be driven by the drive motor, which is disposed over the protective cover, to rotate to polish a workpiece
