Furniture Hinge Decelerating Device Retaining Protrusion Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decelerating hinge devices for furniture doors, particularly those with a front frame, face issues with unreliable fixation of the decelerating device, leading to potential disengagement and difficulties in assembly due to snap coupling and gaps between the hinge box and door insertion holes.
Innovation Solution
A decelerated hinge design featuring a hinge box with openings in its front and/or side walls and a housing body with retaining protrusions that anchor the decelerating device, utilizing fixing means such as bent fixing wings to ensure secure attachment within the hinge box, allowing for stable operation and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If snap coupling is used to fix the decelerating device in the hinge box, then assembly is simplified, but the fixing becomes unreliable and the decelerating device may release
Solution Approach 1:
The fixing system is divided into multiple independent components: the retaining protrusion on the housing body, the opening in the hinge box, and the separate fixing means (screws or clips). This segmentation allows each component to perform its specific function - the protrusion provides positioning, the opening allows insertion, and the fixing means provides secure anchoring - thereby achieving both ease of assembly and high reliability
Solution Approach 2:
The retaining protrusion is integrated into the housing body of the decelerating device, creating a nested structure where the protrusion is part of the housing. This nested design ensures that the fixing components are pre-positioned and aligned, simplifying the assembly process while maintaining reliable fixation when the fixing means is applied
2Adaptability or versatility
If the hinge box is connected to the door with gaps, then assembly flexibility is improved, but the hinge may disengage from the door before screw fixation
Solution Approach 1:
The retaining protrusion and opening are designed to engage before the final screw fixation is applied. This preliminary action creates an initial mechanical connection that prevents the hinge from disengaging during the assembly process, allowing assembly flexibility while ensuring connection stability before the permanent fixation is complete

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reliably fixed decelerating device that prevents disengagement and simplifies the assembly process by using retaining protrusions and fixing wings to securely anchor the housing body to the hinge box, ensuring stable operation and preventing premature disengagement from the door.
Implementation Method 1
a linear-type decelerating device comprising a slider, a fluid damper and elastic return means
Implementation Method 2
elastic closing means, for example in the form of torsion springs positioned at the side walls of the box, or in the form of a leaf spring fixed inside the box
