Flat Panel Hood Mounting Rail for Precise Cabinet Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of flat panel hoods in kitchen furniture is complex due to the need for precise positioning at head height, limited access due to base cabinets and worktops, and the challenge of accommodating different body thicknesses, particularly between 16 mm and 19 mm, which has not been possible with existing solutions.
Innovation Solution
An extractor device with a flat panel hood and a non-destructively separable assembly aid featuring a vertical stop element and mounting strips that can be easily attached to the underside of the kitchen furniture, allowing for precise positioning and alignment without adhesives, using identical and symmetrical mounting rails and a drilling template for accurate placement and screwing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional mounting brackets and screws are used to install flat panel hoods, then the hood can be securely mounted, but the assembly process becomes complex and time-consuming requiring multiple steps including attaching brackets, positioning, pre-drilling, and fastening
Solution Approach 1:
The patent extracts the positioning and mounting functions from the traditional multi-component bracket system and consolidates them into a single integrated mounting rail that combines the rail body, positioning elements, and fastening features into one piece, eliminating the need for separate brackets and simplifying the installation process
Solution Approach 2:
The mounting rail is designed as a universal component that can be used with different body thicknesses (16mm, 18mm, and 19mm) through adjustable positioning mechanisms, eliminating the need for different bracket types for different thicknesses and making the same mounting rail suitable for various installation scenarios
2Measurement precision
If precise positioning is required at head height with limited access, then the hood can be correctly positioned, but the installation becomes more difficult and time-consuming
Solution Approach 1:
The mounting rail includes pre-formed positioning elements such as stop elements and guiding features that are manufactured in advance during rail production, allowing the installer to simply attach the rail and achieve precise positioning without complex measurements or adjustments during installation
Solution Approach 2:
The mounting rail acts as an intermediary component between the hood and the cabinet, providing a standardized interface with built-in positioning features that simplify the connection process and ensure accurate positioning without requiring precise manual measurement and adjustment
3Manufacturing precision
If mounting strips are designed for specific body thicknesses, then precise positioning is achieved, but the solution cannot accommodate different body thicknesses of 16mm, 18mm, and 19mm
Solution Approach 1:
The mounting rail incorporates adjustable and adaptable features such as movable positioning elements and flexible mounting mechanisms that can be adjusted to accommodate different body thicknesses (16mm, 18mm, 19mm) while maintaining precise positioning, allowing the same rail design to dynamically adapt to various installation requirements
4Reliability
If multiple mounting components and steps are used, then secure attachment is achieved, but the installation time increases and the process becomes less intuitive
Solution Approach 1:
The patent merges multiple mounting functions (positioning, support, and fastening) into a single integrated mounting rail component that performs all these functions simultaneously, eliminating the need for multiple separate mounting steps and components while maintaining secure attachment and reducing installation time
