Hinge Unit Damper Installation via Securing Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hinge units with damping members face issues such as leakage of damping material over time, leading to a loss of buffering feature, and existing solutions either expose the damper, occupying space and affecting aesthetics, or are difficult to replace.
Innovation Solution
A hinge unit design featuring a securing frame with a damper connected between the hinge arm and base, utilizing a piston and body with recessed areas and protrusions for secure engagement, allowing for easy replacement and integration within the hinge unit, maintaining aesthetics and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the damper is exposed to provide easy replacement, then the ease of repair is improved, but the aesthetic feature and space occupation deteriorate
Solution Approach 1:
The damper is nested within the hinge arm structure, specifically housed in a cavity formed by the side walls and bottom wall. The securing frame with its engaging member provides a protective enclosure that integrates the damper into the hinge unit's internal structure, making it invisible from the exterior while maintaining accessibility for replacement through the designed opening mechanism.
2Shape
If the damper is integrated within the hinge unit to maintain aesthetics, then the aesthetic feature is improved, but the ease of repair deteriorates
Solution Approach 1:
The hinge unit is segmented into distinct functional components: the hinge arm with its side walls and bottom wall forming a cavity, the securing frame with engaging members, and the damper as a separate replaceable component. This segmentation allows the damper to be easily accessed and replaced through the opening mechanism while remaining integrated within the overall hinge unit structure, thus maintaining both aesthetics and ease of repair.
3Reliability
If the damping material is sealed within the damper, then the reliability is improved, but the ease of repair deteriorates
Solution Approach 1:
The damper assembly, including the damping material sealed within the damper body, is designed as a complete extractable unit. The securing frame with its engaging members allows the entire damper assembly to be removed as one unit from the hinge arm cavity, enabling easy replacement of the sealed damping material without disassembling the hinge structure itself, thus maintaining both reliability and ease of repair.

AI summary
A hinge unit includes a hinge arm which defines a room in which a securing frame is installed. The securing frame includes two side panels with an engaging member connected therebetween. Each of the two side panels has an engaging portion on the inside thereof. The engaging member has a through hole and a protrusion extends from the periphery of the through hole. A damper has a body and a piston. The body has a front end portion having a recessed area, and a rear end portion having a protrusion. A fixing member connects the securing frame to the hinge arm. The piston extends through the through hole and the protrusion is engaged with the recessed area, the body of the damper is installed between the two side panels. The contact portion of the body contacts the engaging portion.
