Dust Collection Hose Support for Handheld Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dust collection systems for handheld power tools are inefficient in maintaining a secure connection between the dust hose and the tool, especially when the tool is moved freely, and often require adapters to connect with vacuum sources having different hose diameters, leading to convenience and interconnection issues.
Innovation Solution
A dust collection attachment system featuring a flexible dust hose with a hose support clasp that securely attaches to the power tool and a compact adapter for interconnecting with various diameter hoses, ensuring a stable connection and compatibility with different vacuum sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible dust hose is used without a secure mounting mechanism, then the hose can be easily attached and removed, but the hose becomes disconnected during tool movement
Solution Approach 1:
The patent employs a flexible dust hose that can bend and move with the tool while maintaining connection integrity. The hose's flexibility allows it to accommodate tool movement without disconnection, resolving the contradiction between ease of attachment and connection stability during operation.
Solution Approach 2:
The hose support system is designed to be dynamic rather than rigid, allowing the hose to move with the tool while maintaining secure attachment. This dynamic approach enables the hose to adapt to tool movement, preventing disconnection while remaining easy to attach and remove.
2Reliability
If a rigid hose support system is used to prevent disconnection, then the hose connection remains stable, but the system becomes more complex and difficult to attach/detach
Solution Approach 1:
The hose support system is divided into separate components: a hose support body, a mounting clasp, and a retaining clip. This segmentation allows each component to perform its specific function while keeping the overall system simple and easy to assemble/disassemble, reducing complexity while maintaining stability.
Solution Approach 2:
The mounting clasp and retaining clip are designed to be easily engaged and disengaged, providing a simple dynamic attachment mechanism rather than a permanent rigid connection. This reduces the complexity of the support system while ensuring stable hose connection during tool operation.
3Device complexity
If a single hose diameter is used for dust collection, then the system is simpler, but it cannot connect to vacuum sources with different hose diameters
Solution Approach 1:
The adapter component is designed to interface with multiple vacuum source types and hose diameters, making the dust collection system universally compatible. This multi-functional adapter allows a single hose diameter to connect to various vacuum sources, resolving the contradiction between system simplicity and adaptability.
Solution Approach 2:
The adapter acts as an intermediary component between the dust hose and various vacuum source connections. This mediator enables compatibility with different hose diameters without requiring multiple hose sizes, maintaining system simplicity while achieving versatility.
4Adaptability or versatility
If adapters are required to connect to different vacuum sources, then compatibility is achieved, but the system becomes more complex and less convenient
Solution Approach 1:
The adapter is designed with universal compatibility for multiple vacuum source types and hose diameters in a single component. This multi-functionality eliminates the need for multiple different adapters, maintaining connection convenience while achieving broad compatibility across different vacuum sources.
