Furniture Hinge Device with Segmented Vertical and Horizontal Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge devices for furniture require complex and large adjustment mechanisms, necessitating significant effort and potentially causing wear, while also requiring re-adjustment of connected parts, and do not allow for easy installation or later modifications.
Innovation Solution
A hinge device with a displaceable stop profile and adjustable stop hinges, featuring a support device with a slide and holding device that allows for easy height adjustment and secure locking, enabling precise alignment and reduced wear, with the option to mount multiple hinges without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjustable drive is used to move the stop profile vertically, then the door element can be adjusted vertically, but the drive becomes complex and requires larger dimensions
Solution Approach 1:
The adjustment function is divided into two independent parts: vertical adjustment of the stop profile (affecting both door elements) and horizontal adjustment of individual door elements via stop hinges. This segmentation allows simple vertical positioning without complex integrated drives.
Solution Approach 2:
The stop profile serves multiple functions: it provides vertical positioning for both door elements simultaneously and acts as a mounting structure for the stop hinges. This multi-functionality eliminates the need for separate adjustment mechanisms.
2Adaptability or versatility
If an adjustable drive is used to move the stop profile vertically, then the door element can be adjusted vertically, but the drive requires larger dimensions
Solution Approach 1:
Vertical adjustment is achieved through a simple mechanism that affects both door elements simultaneously, while horizontal adjustment is handled by compact stop hinges. This segmentation keeps each adjustment mechanism small and space-efficient.
3Adaptability or versatility
If the stop hinges are made adjustable to move the door element horizontally, then horizontal alignment is improved, but wear signs occur after repeated adjustments
Solution Approach 1:
The traditional rack-and-pinion mechanism is replaced with a lever-based mechanical advantage system. The lever arm provides adjustment capability through force multiplication, reducing wear on the mounting lever while maintaining adjustability.
4Manufacturing precision
If the stop profile is made displaceable for adjustment, then alignment precision is improved, but other connected parts must also be readjusted
Solution Approach 1:
The adjustment system is segmented into independent vertical (stop profile) and horizontal (stop hinges) functions. This allows vertical repositioning without affecting horizontal alignment, and vice versa, eliminating the need for complete readjustment of all components.
5Strength
If multiple stop hinges are mounted on the stop profile, then higher loads can be carried, but the adjustment of one hinge may be hindered by the second hinge
Solution Approach 1:
Multiple stop hinges are arranged in different spatial dimensions (vertically stacked or laterally spaced) on the stop profile. This dimensional arrangement allows each hinge to be accessed and adjusted independently without interference from others, while collectively supporting higher loads.
