Hinge Damping Device with Toggle Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional damping devices for furniture parts require an extra operation to activate the damping function, which is inconvenient and lacks user control over the damping mechanism.
Innovation Solution
A hinge assembly damping device with a spring mechanism, a maintaining member, and an adjustment member that allows users to easily toggle the damping function on or off by moving the adjustment member between two positions, engaging or disengaging the damper's piston rod with a protruded portion, thereby controlling the damping action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slider is positioned by the locking device contact, then the damping function is activated, but an extra operation action is required which reduces ease of operation
Solution Approach 1:
The hinge assembly automatically activates the damping function through its own closing motion. When the hinge closes, the arm pushes the slider along the inclined abutment surface, causing the locking element to automatically contact the locking member and engage the damping mechanism, eliminating the need for separate user activation
Solution Approach 2:
The slider is pre-positioned with a protruding portion that extends into the housing chamber, ready to contact the arm during hinge closing. The locking element is pre-configured to automatically engage with the locking member when the slider moves along the inclined surface, so the damping function is prepared and activated in advance during normal hinge operation
2Ease of operation
If the slider protrudes automatically, then the damping function is always available, but user control over the damping mechanism is lost
Solution Approach 1:
The hinge assembly dynamically switches between damping and non-damping modes based on the user's adjustment of the slider position. The slider can be moved to different positions along the inclined abutment surface, allowing the user to control when and how the damping function activates, providing adaptability while maintaining ease of operation
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
Enables users to conveniently turn the damping function on or off, ensuring smooth and quiet operation of doors or cabinets by allowing controlled engagement of the damper, enhancing user experience and functionality.
Implementation Method 1
A spring is located in the chamber to provide to allow the pivotal movement between the housing and the arm
Implementation Method 2
the damper is pushed by the arm, so that the piston rod of the damper contacts the protruded portion of the adjustment member and retracts to perform damping function

AI summary
A hinge assembly includes a housing, an arm and at least one spring. A damping device includes a damper having a piston rod, a maintaining member secured in the housing and an adjustment member. The adjustment member is movably connected to the maintaining member and has a protruded portion located corresponding to the piston rod of the damper. When the adjustment member is moved to a first position relative to the maintaining member, the protruded portion of the adjustment member is located toward the piston rod of the damper, so that the piston rod contacts the protruded portion and retracts to perform damping function. When the adjustment member is moved to a second position relative to the maintaining member, the protruded portion of the adjustment member is moved away from the piston rod of the damper, and no damping function is available.
