Innovation Solution
A damping type universal arm support that connects two objects through a first assembly and a second assembly, utilizing a damping sleeve piece for stepless adjustment and a limiting assembly to clamp and limit rotation, featuring a cooperative design with components like a damping sleeve piece, limiting assembly, and movable arms with ball heads and ejector rods for precise control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional universal arm structure is used, then the structure is simple, but fast and precise adjustment cannot be achieved
Solution Approach 1:
The universal arm is divided into multiple assemblies (first assembly, second assembly, damping sleeve piece, limiting assembly) that can independently function and be adjusted. Each assembly handles specific functions (connection, damping, limiting), allowing precise control without requiring complete structural redesign.
Solution Approach 2:
The damping sleeve piece enables dynamic adjustment of the universal arm's positioning characteristics. By allowing stepless adjustment during movement and providing damping effects, the system transitions from static fixed positions to dynamic可调 positioning, achieving fast and precise adjustment.
2Measurement precision
If a damping sleeve piece with stepless adjustment is added, then adjustment precision is improved, but device complexity increases
Solution Approach 1:
The damping sleeve piece serves multiple functions simultaneously: it provides stepless adjustment capability, offers damping effects during movement, and enables clamping through the limiting assembly. This multi-functionality reduces the need for separate components for each function, thereby limiting overall complexity increase.
Solution Approach 2:
The damping sleeve piece is nested within the assembly structure, with the limiting assembly integrated at its end. This nested configuration allows compact arrangement of multiple functional components without requiring excessive space or complex external linkages.
3Stability of the object's composition
If the limiting assembly is used to clamp and limit rotation, then positioning stability is improved, but adjustment flexibility may be reduced
Solution Approach 1:
The limiting assembly operates in a periodic manner: during adjustment phases, it allows free movement; during positioning phases, it engages to provide clamping and limiting rotation. This periodic engagement/disengagement cycle enables both flexible adjustment and stable positioning without permanent constraint.
Solution Approach 2:
The system changes its mechanical parameters dynamically: when adjustment is needed, the limiting assembly disengages allowing free rotation; when positioning is required, it engages to provide clamping force and limit rotation. This parameter change between free and constrained states enables both flexibility and stability.

Function Achieved in This Case
Enables stepless adjustment and real-time angle adjustment without loosening or locking, providing a damping effect and allowing the device to hover under an allowable weight, with a locking force that can be adjusted based on applied pressure.
Implementation Method 1
the damping sleeve piece can be clamped through a limiting assembly, and therefore, the damping effect during connection of the first assembly and the second assembly is achieved
Implementation Method 2
a first ball head is connected to the top of the first ball head limiting housing in a ball hinge mode
Implementation Method 3
a lower end of the first ball head limiting housing is in threaded connection with the first movable arm through a first fixing screw
