Adjustable Hinge Damper with Segmented Contact Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing damping devices for hinges only have an ON or OFF damping state, lacking a mechanism to adjust the damping function, which limits their operational flexibility.
Innovation Solution
A hinge with a damping device featuring an adjusting member with multiple contact portions and engaging parts, allowing the piston rod of the damper to produce different damping effects by adjusting the position of the adjusting member, enabling various damping actions based on the desired operational needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a simple damper structure is used, then the device complexity is reduced, but the adaptability of damping adjustment is lost
Solution Approach 1:
The adjusting member is designed to be movable relative to the retainer, allowing the damping characteristic to be dynamically changed by shifting the adjusting member to different positions. This enables the hinge to adapt to different damping requirements without requiring multiple separate dampers.
Solution Approach 2:
The adjusting member is divided into multiple contact portions (first contact portion, second contact portion, third contact portion) at different distances from the surface. Each contact portion corresponds to a specific damping level, allowing selective engagement with the piston rod to achieve different damping effects.
2Ease of operation
If a damper with fixed damping characteristic is used, then the device complexity is reduced, but the operational flexibility for different closing speeds is limited
Solution Approach 1:
The adjusting member can be moved to different positions to change the damping characteristic in real-time, allowing the hinge to be adapted to different operational requirements such as different closing speeds or door weights without replacing the entire damper assembly.
Solution Approach 2:
By changing the position of the adjusting member, the physical parameter of damping force is adjusted. The piston rod engages with different contact portions at different distances from the surface, thereby changing the damping force parameter to suit different operational needs.
3Manufacturing precision
If only ON/OFF damping states are provided, then the device complexity is reduced, but the precision of damping control is insufficient
Solution Approach 1:
The adjusting member is segmented into multiple discrete contact portions, each providing a specific damping level. This segmentation allows for precise control of the damping force by selecting which contact portion engages with the piston rod, rather than providing only a single ON/OFF state.
Solution Approach 2:
The invention provides multiple discrete damping parameter levels through the different contact portions. By engaging the piston rod with different contact portions at different distances from the surface, precise control over the damping force parameter is achieved.
Applied Scientific Principles
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 allows for selective adjustment of damping actions, providing the necessary damping effect to satisfy operational needs in closing doors or similar applications, enhancing functionality and noise reduction.
Implementation Method 1
The at least one spring is mounted in the room of the hinge cup and serves to provide a resilient closing force when the hinge cup is pivoted with respect to the hinge arm
Implementation Method 2
the piston rod of the damper is pressed against the first contact portion of the adjusting member and produces a damping effect

AI summary
A hinge includes a hinge arm, a hinge cup, a spring, a retainer, a damper, and an adjusting member. When the hinge cup, which is pivotally connected to the hinge arm, is being closed relative thereto, the spring provides a resilient closing force to complete the closing action. The retainer is mounted in the hinge cup and has a channel. The damper is mounted in the channel and corresponds to the hinge arm to provide a damping force adjustable via the adjusting member, which is movably mounted to the retainer, includes a surface and at least two contact portions differently spaced from the surface, and can be adjusted relative to the retainer so that one of the contact portions corresponds to the damper.
