Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction nozzles for hand-held milling machines are cumbersome to mount and remove, often requiring tools, leading to incomplete dust extraction and increased risk of damage during falls.
Innovation Solution
A suction nozzle with a releasable attachment mechanism to a depth stop, featuring a snap closure system with latching elements and a spring element for easy installation and detachment, and a ring-shaped design for optimal dust extraction, along with a transparent plastic construction for visibility and blockage detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction nozzle is firmly mounted on the hand-held milling machine, then the dust extraction reliability is improved, but the device complexity and risk of damage during falls increase
Solution Approach 1:
The suction nozzle is divided into separate components: a body portion and a mounting portion with attachment elements. This segmentation allows the nozzle to be easily assembled and disassembled while maintaining reliable dust extraction when mounted, resolving the contradiction between firm mounting and ease of assembly.
2Reliability
If the suction nozzle is firmly mounted on the hand-held milling machine, then the dust extraction reliability is improved, but the damage risk during falls increases
Solution Approach 1:
The resilient attachment elements are designed to act as a cushioning mechanism that absorbs impact forces during falls. The resilient nature of these elements allows them to deform and absorb energy, protecting the suction nozzle from damage while maintaining reliable mounting during normal operation.
3Reliability
If a special tool is required for mounting the suction nozzle, then the mounting security is improved, but the ease of operation deteriorates
Solution Approach 1:
The attachment elements are designed to self-secure when the suction nozzle is mounted on the depth stop, eliminating the need for special tools. The resilient nature of the attachment elements allows them to automatically engage and secure the mounting position through their own elastic properties, providing both ease of operation and mounting security.
4Stability of the object's composition
If the suction nozzle is cumbersome to assemble, then the mounting stability is improved, but the productivity deteriorates
Solution Approach 1:
The suction nozzle is segmented into a body portion and a mounting portion with integrated attachment elements. This segmentation enables quick assembly and disassembly without compromising mounting stability, as the attachment elements are designed to securely engage with the depth stop while allowing rapid installation.
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
Facilitates safe and efficient dust extraction by simplifying the attachment and detachment process, reducing the likelihood of damage from falls, and ensuring effective dust collection around the milling tool.
Implementation Method 1
a first of the latching elements (11) is formed rigidly on the connection area (10) and/or a second of the latching elements (11') is formed resiliently on the connection area (10) by means of a spring element (15)
