Buffer Assembly with Dynamic Clamping Ring for Rapid Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buffer assemblies, such as damping gears, face issues with damping properties changing due to temperature and humidity, leading to reduced or lost buffering effects, and components become stuck, making quick disassembly difficult.
Innovation Solution
A buffer assembly comprising a screw rod, a base, a rotating element, and a clamping ring that can switch between connected and open states, allowing the screw rod to pass through without interference, enabling rapid assembly and disassembly by aligning or misaligning the position-limiting space with the rotation axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If damping oil is added to the damping gear to increase friction and achieve buffering effect, then the buffering effect is improved, but the damping properties change with temperature and humidity causing the buffering effect to attenuate or disappear
Solution Approach 1:
The patent removes the damping oil from the damping gear structure, extracting the problematic element that caused variable damping properties. The buffering function is achieved through the mechanical interaction between the screw rod, rotating element, and clamping ring without requiring any fluid medium, thereby eliminating the issue of damping property changes with temperature and humidity.
Solution Approach 2:
The patent replaces the fluid-based damping mechanism (damping oil) with a pure mechanical buffering system. The buffering effect is achieved through the mechanical friction and interaction between the screw rod threads, rotating element, and clamping ring, substituting the hydraulic/pneumatic damping approach with a solid-mechanics-based solution.
2Reliability
If the damping gear is designed to provide buffering during assembly, then the buffering function is achieved, but the components become stuck and cannot be removed quickly
Solution Approach 1:
The patent introduces a dynamic clamping ring that can switch between two states: a connected state during assembly where the clamping ring engages with the rotating element to provide buffering, and an open state during disassembly where the clamping ring moves away to allow the screw rod to pass through freely. This dynamic state change enables the system to adapt its mechanical engagement level based on the operational phase.
Solution Approach 2:
The patent segments the buffering mechanism into separable components: the clamping ring, rotating element, and screw rod. The clamping ring can be detached from the rotating element along the connection axis, allowing the buffering function to be activated only when needed during assembly, while enabling quick disassembly by separating the components.
3Productivity
If the clamping ring is detachably connected to allow quick disassembly, then the disassembly speed is improved, but the buffering effect may be compromised
Solution Approach 1:
The clamping ring is designed with dynamic capability to transition between connected and detached states. During assembly, the clamping ring is connected to the rotating element, providing the necessary buffering effect through mechanical friction. During disassembly, the clamping ring is detached along the connection axis, allowing the screw rod to pass through without interference, achieving quick disassembly without compromising the buffering effect during the assembly phase.
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 buffer assembly maintains effective buffering during assembly while allowing for quick disassembly by ensuring the screw rod can move freely without contacting the clamping ring in the open state, enhancing disassembly efficiency.
Implementation Method 1
add damping oil to the damping gear to increase friction and achieve a buffering effect
Implementation Method 2
the screw rod pushes the clamping ring to rotate so that the screw rod passes through the position-limiting space and the through hole

AI summary
A buffer assembly includes a screw rod, a base, a rotating element and a clamping ring. The rotating element is rotatably disposed on the base along a rotation axis. The rotating element includes a through hole. The clamping ring is detachably connected to the rotating element along a connection axis, so that the clamping ring is adapted to switch to a connected state or an open state. The clamping ring includes a position-limiting space, and the rotation axis is perpendicular to the connection axis. When the clamping ring is in the connected state, the position-limiting space and the through hole are located on the rotation axis, and the screw rod pushes the clamping ring to rotate so that the screw rod passes through the position-limiting space and the through hole. When the clamping ring is in the open state, the position-limiting space is misaligned with the rotation axis.
