Hinge Buffer Device with Tool-Free Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hinge buffer devices require complex adjustments and realignments, often necessitating multiple bolts, which is inconvenient and prone to hardware fatigue, especially when the elastic buffer members fail to provide sufficient resistance and alignment.
Innovation Solution
A hinge buffer device comprising a casing with a sliding trough, a buffer cylinder, and an adjustable bolt with a knob, allowing for easy positioning and force adjustment without tools, enabling the buffer to slow down the panel's closure by engaging with the hinge extension arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional buffer devices use multiple bolts for adjustment, then alignment precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The adjustment mechanism is segmented into a bolt, a slot, and a knob, allowing independent adjustment of position and alignment without requiring multiple bolts simultaneously
Solution Approach 2:
The slot acts as an intermediary element between the bolt and the buffer member, enabling alignment adjustment through the bolt's lateral movement within the slot without requiring a second alignment bolt
2Manufacturing precision
If conventional buffer devices require tool-based adjustment, then adjustment precision is improved, but ease of operation deteriorates
Solution Approach 1:
The knob enables the user to directly engage and adjust the bolt without requiring external tools, making the adjustment process self-service and tool-free while maintaining precision through the threaded mechanism
3Force
If buffer members are made of elastic elements, then buffer force is improved, but reliability deteriorates due to hardware fatigue
Solution Approach 1:
The buffer force parameter is adjusted by changing the compression distance of the elastic element through position adjustment of the buffer member, allowing optimization of buffer force while extending the service life of the elastic element
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 device simplifies the adjustment process, reduces production costs, and ensures easy operation by allowing tool-free adjustment, effectively preventing direct panel-to-cabinet contact through adjustable buffer positioning and force, enhancing the buffer's effectiveness over time.
Implementation Method 1
The hinge arm is provided with an elastic member to restore the panel back to its original position
Implementation Method 2
The adjustment comprises a bolt to be connected with the threaded hole of the casing. By screwing the bolt, the slide is adjustable with respect on the casing

AI summary
A hinge buffer device includes a casing, a slide, a buffer and an adjustment. The casing comprises a first end, a second end, a pair of lugs, a threaded hole, and a sliding trough. The lugs are disposed at two sides of the first end of the casing. The threaded hole is formed at the second end of the casing. The sliding trough is located between the first end and the second end of the casing. The slide comprises a compartment, a pair of sliding sections at respective sides to be engaged with the sliding trough of the casing. The buffer is a cylinder to be mounted in the compartment of the slide. The buffer comprises a piston rod secured to the slide. The adjustment is connected to the slide, and comprises a bolt to be engaged with the threaded hole of the casing.
