Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinge assemblies with damping devices suffer from insecure mounting and easy loosening when subjected to impact, leading to ineffective damping performance.
Innovation Solution
A hinge assembly design featuring a damping device with a piston rod, slide, and housing, where the damping member is securely engaged with the hinge cup using resilient members and pins, allowing for adjustable damping travel and stable force application, ensuring the damping device remains securely mounted and functional.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the damping device is installed using a resilient arresting element and opening, then the installation is simple, but the connection is not secure enough and the damping device is easily loosened when hit by the hinge lever
Solution Approach 1:
The connection system is divided into multiple independent engagement points: the resilient arresting element provides initial retention, while additional engagement features (such as positioning elements and securing mechanisms) provide redundant connection points. This segmentation ensures that if one connection point is subjected to impact, other points maintain the secure connection.
Solution Approach 2:
The resilient arresting element is designed to deflect and absorb impact forces before they can loosen the damping device. This preliminary cushioning action protects the connection from the full force of hinge lever impacts, maintaining connection security while keeping the installation simple.
2Reliability
If the damping device is securely mounted with multiple engagement points, then the connection security is improved, but the device complexity increases
Solution Approach 1:
Multiple engagement features are integrated into a unified housing structure. The positioning elements, securing mechanisms, and resilient arresting element are combined within the single damping device housing, providing secure multi-point connection without requiring separate mounting components or complex assembly procedures.
Solution Approach 2:
The damping device incorporates self-positioning and self-securing features that automatically engage with the hinge cup during installation. The resilient arresting element and positioning elements work together to automatically secure the device in the correct position, eliminating the need for complex alignment procedures or additional fastening steps.

Function Achieved in This Case
The solution provides a securely mounted damping device that effectively absorbs impact, ensuring smooth and quiet operation of the hinge assembly by maintaining the damping function throughout the range of motion, with adjustable travel to accommodate varying conditions.
Implementation Method 1
a first resilient member connected between the first lug and the first side wall so as to provide a force to the arm; a second resilient member connected between the second lug and the second side wall so as to provide a force to the arm
Implementation Method 2
A damping device is located in the receiving space of the hinge cup and has a damping member, a slide and a housing

AI summary
A hinge assembly includes a hinge cup, an arm, an installation member and a damping device. The hinge cup has a receiving space and a positioning hole communicating with the receiving space. The bottom wall of the receiving space has at least one first engaging part. The arm is pivotably connected to the hinge cup. The damping device is located in the receiving space and includes a damping member, a slide and a housing. One end of the damping member is mounted in the positioning hole. The damping member has a piston rod which is connected to the slide. The housing has at least one second engaging part which is engaged with the first engaging part on the bottom wall. When the arm is moved toward a closed position relative to the hinge cup, the arm pushes the slide to provide the damping force.
