Hood with fastening device for a surface element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extractor hood designs face issues with contamination and difficulty in handling due to handles that interrupt the surface and are exposed to airflow, making attachment and removal of surface elements cumbersome.
Innovation Solution
A fastening device with a pivotably mounted surface element, utilizing a sliding element with a magnet and push-push mechanism that allows for magnetic attachment and detachment without mechanical extendable pins, simplifying the structure and handling by eliminating the need for handles and reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handle with mechanical fastening pins is used to attach the surface element, then the surface element can be securely fixed to the extractor hood, but the surface is interrupted and the handle is exposed to airflow causing contamination
Solution Approach 1:
The patent removes the handle and mechanical pin components from the surface element, extracting the contaminating elements while retaining the fastening function through a magnet-based system. The surface element becomes handle-less, eliminating the interruption in surface continuity and the exposure to airflow.
Solution Approach 2:
The patent replaces the mechanical pin-based fastening system with a magnetic fastening system. Instead of using physical pins that require handles for manipulation, the invention uses magnetic attraction between a magnet in the extractor hood and a ferromagnetic material in the surface element, eliminating the need for handles and reducing contamination risk.
2Reliability
If mechanical pins and handles are used for attachment, then the surface element can be fixed securely, but the structure becomes more complex and handling becomes more difficult
Solution Approach 1:
The patent extracts the handle and mechanical pin components from the design, simplifying the overall structure. The surface element becomes a simpler, handle-less component that integrates the ferromagnetic material directly into its body, reducing the number of parts and structural complexity.
Solution Approach 2:
The patent replaces the complex mechanical pin-and-handle system with a simpler magnetic attraction system. This substitution reduces the number of moving parts, eliminates the need for handles, and simplifies both the structure and the attachment/detachment process.
3Reliability
If mechanical pins are used for fastening, then the surface element can be securely mounted, but the handling and removal process becomes more cumbersome
Solution Approach 1:
The patent replaces the mechanical pin-based fastening system with a magnetic fastening system, enabling easier handling and removal. The magnetic attraction allows the surface element to be securely mounted during operation but easily detached by overcoming the magnetic force, eliminating the need for handles and complex manipulation.
Solution Approach 2:
The magnetic fastening system provides self-aligning and self-holding functionality. The ferromagnetic material in the surface element is automatically attracted to the magnet in the extractor hood, providing secure mounting without requiring precise alignment or manual manipulation of mechanical pins.
