Dust Suppression Assembly for Handheld Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust suppression technologies for handheld devices like rock drills and concrete hammers are inefficient due to suboptimal positioning and increased operator burden, leading to health risks and productivity issues.
Innovation Solution
A dust suppression assembly that integrates a mist spray and vacuum suction system, affixed to the handheld device, allowing for optimal dust suppression by positioning the mist spray and vacuum cup at a predetermined distance from the tool's working end, with easy assembly and disassembly features for tool changes without dismantling the suppression system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a vacuum suction unit is added as an extra attachment to reduce dust, then dust suppression capability is improved, but operator burden increases and productivity decreases
Solution Approach 1:
The dust suppression assembly is merged with the handheld device by affixing it to the body, combining the suppression function with the tool itself rather than using a separate vacuum unit. This integration eliminates the need for operators to manage additional equipment while maintaining effective dust suppression at the source.
Solution Approach 2:
The dust suppression assembly is designed to be easily attached and detached by the operator without requiring dismantling or complex operations. The simple affixing mechanism allows operators to quickly set up and remove the assembly themselves, maintaining productivity while enabling effective dust control when needed.
2Ease of manufacture
If the dust suppression means are positioned suboptimally with respect to the work surface, then assembly simplicity is improved, but dust suppression effectiveness deteriorates
Solution Approach 1:
The dust suppression assembly is designed to be affixed at a specific location on the body that positions the suppression means optimally close to the tool's working end. This localized positioning ensures water is delivered precisely where dust is generated, maximizing suppression effectiveness while maintaining simple assembly through the affixing mechanism.
3Object-affected harmful factors
If the dust suppression assembly is integrated onto the handheld device, then dust suppression effectiveness is improved, but device complexity increases
Solution Approach 1:
The dust suppression assembly is designed as a separate, modular component that can be affixed to the body rather than being permanently integrated. This segmentation allows the suppression function to be added or removed independently, maintaining simple device architecture while enabling effective dust suppression when required.
4Ease of operation
If the retainer and tool changing mechanism are made accessible without dismantling, then ease of operation is improved, but structural complexity increases
Solution Approach 1:
The device interface member is designed with an asymmetric opening or access feature that allows the retainer to be operated from one specific direction or position. This asymmetric design enables tool changing without dismantling the assembly from the opposite side, improving operational ease while adding minimal structural complexity through the targeted access feature.
