Adjustable Furniture Fitting Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture fittings with limiting devices for preventing collisions with adjacent cupboards or ceilings require different-sized clamps for varying opening angles and risk detachment, leading to inconsistent pivot angle limitation.
Innovation Solution
A furniture fitting with an adjustable actuating element that allows for continuous or fixed adjustment of the opening angle, featuring a movably mounted stop that can be manually or tool-basedly operated to limit the pivoting path, ensuring secure and customizable angle limitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamps are used to limit the opening angle of the furniture fitting, then the maximum pivoting path can be restricted to prevent collisions, but different-sized clamps are required for different opening angles and the clamps may come loose from the hinge axis
Solution Approach 1:
The patent applies the dynamics principle by making the stop position adjustable rather than fixed. The actuating element allows the stop to be moved along the hinge axis to different positions, enabling the same limiting device to accommodate various opening angles dynamically. This resolves the contradiction by eliminating the need for multiple clamp sizes while maintaining reliable angle limitation through a single adaptable component.
2Reliability
If clamps are used to limit the opening angle, then the maximum pivoting path can be restricted, but the clamps risk coming loose and getting lost
Solution Approach 1:
The patent merges the stop function with the limiting device by integrating the stop into the structure of the limiting device itself. The stop becomes an inherent part of the mechanism rather than a separate removable clamp, ensuring it cannot detach or be lost while still allowing reliable pivot angle limitation through the integrated design.
3Adaptability or versatility
If a fixed stop position is used in the limiting device, then the structure is simple, but the opening angle cannot be adjusted to different values
Solution Approach 1:
The patent applies dynamics by transforming the static stop position into a dynamic, adjustable one. The actuating element enables the stop to be repositioned along the hinge axis, allowing the opening angle to be adapted to different values. This added functionality is achieved through a relatively simple actuating mechanism that does not significantly complicate the overall device structure.
