A mounting tool for a connection system of a door of a built-in domestic appliance to a door of a furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection of a built-in refrigerator door to a kitchen furniture door is complex, requiring manual skill and precise measurements, making it difficult for unskilled operators and increasing costs due to the need for accurate alignment and fixation of a sliding connection system.
Innovation Solution
A mounting tool that removably couples to the sled and guide profile, featuring a main body with a seat for the guide profile, a coupling plate, and a reference plate to facilitate alignment and fixation, minimizing friction and ensuring correct placement, and includes a tubular invitation element for easy screw insertion and snap-on fixing system for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sliding connection system is used to connect the door of a built-in refrigerator to the door of kitchen furniture, then the door can open and close simultaneously, but the alignment and fixation process becomes complex and requires manual skill
Solution Approach 1:
The patent introduces a mounting tool as an intermediary device that mediates between the sled and guide profile. This tool includes a reference element that aligns with a reference feature on the furniture door, and a positioning element that aligns with a positioning feature on the sled, thereby simplifying the complex alignment process into a straightforward mechanical guidance system
Solution Approach 2:
The mounting tool performs preliminary alignment actions before the actual fixation. The reference element and positioning element pre-establish the correct spatial relationship between the guide profile and sled, allowing the installer to simply follow the mechanical guidance rather than performing complex measurements and calculations
2Manufacturing precision
If precise measurements and alignment are performed to correctly position the guide profile, then the sliding connection works properly with minimal friction, but the installation time and skill requirement increase
Solution Approach 1:
The mounting tool serves as a mechanical intermediary that translates complex precision requirements into simple mechanical alignment. The reference element with its reference feature and the positioning element with its positioning feature create a self-aligning system that eliminates the need for precise measurements by the installer
Solution Approach 2:
The system enables self-aligning through mechanical features. The reference element automatically finds its correct position relative to the furniture door through the reference feature, and the positioning element similarly self-aligns with the sled, making the installation process self-correcting and eliminating time-consuming manual adjustment
3Reliability
If multiple screws are used to fix the guide profile to ensure secure attachment, then the connection reliability improves, but the ease of operation deteriorates due to difficult alignment and insertion
Solution Approach 1:
The mounting tool acts as an intermediary that pre-aligns the screw holes of the guide profile with the corresponding holes in the furniture door. This mechanical guidance system ensures that screws insert easily without requiring complex alignment, while still maintaining secure attachment through multiple screws
Solution Approach 2:
The mounting tool performs the preliminary alignment of screw holes before the actual screw insertion. The reference element and positioning element establish the correct positions in advance, so that when screws are inserted, they automatically follow the pre-established alignment paths, making the operation simple and intuitive
