Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current universal ball joint assemblies are complex, have poor appearance, and rely on multiple elements for angle fixation, making them inefficient and aesthetically unappealing.
Innovation Solution
A rotating assembly with a limit ring, base, spherical friction part, and pressing module, where the base is movable along an axis, and the pressing module compresses the space between the limit ring and base to generate friction, allowing the spherical friction part to maintain a specific angle, enabling easy rotation by overcoming friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw is used to control the degree of the universal spherical head being pushed in the foot stand body, then the universal sphere head can be rotated or fixed at a specific angle, but the structure becomes complex and appearance deteriorates
Solution Approach 1:
The patent removes the traditional screw mechanism from the universal ball joint assembly. Instead of using a screw to push and fix the spherical head, the invention extracts this function and replaces it with a simpler pressing module that applies pressure directly to the base, allowing the spherical friction part to be pressed against the limit ring for fixation without complex threading components
Solution Approach 2:
The patent combines the pressing and fixation functions into a single integrated pressing module. The pressing module integrates the pressing part and elastic part into one component that simultaneously provides both the pressing force and the fixation mechanism, eliminating the need for separate screw threads and multiple adjustment elements
2Reliability
If multiple elements are used to fix the universal spherical head, then the fixation is reliable, but the appearance becomes poor
Solution Approach 1:
The patent merges multiple fixation elements into a single integrated pressing module. Instead of using separate screws, washers, and locking mechanisms, the invention combines these functions into one compact module that maintains reliable fixation while presenting a clean, unified appearance without exposed fastening elements
Solution Approach 2:
The pressing module is designed with a nested structure where the elastic part is contained within the pressing part. This nesting allows the fixation mechanism to be compact and hidden, maintaining a sleek appearance while providing reliable fixation through the nested elastic pressing mechanism
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 simplifies the structure, provides a durable universal ball joint assembly with a simple appearance, allowing for temporary fixation and easy rotation of objects by adjusting friction, enhancing user experience and design aesthetics.
Implementation Method 1
The elastic part is disposed between the base and the pressing part
Implementation Method 2
pushes the base to a direction of the limit ring to compress the space formed by the base and the limit ring so the spherical friction part is in contact with the limit ring and the base to generate friction
Implementation Method 3
The spherical friction part is rotatably disposed in the space between the limit ring and the base... generate friction. The spherical friction part temporarily maintains at a specific angle due to the friction between the spherical friction part and the limit ring and the friction between the spherical friction part and the base

AI summary
A rotating assembly is provided and is adapted to be assembled on a foot stand. The rotating assembly includes a limit ring, a base, a spherical friction part, and a pressing module. The limit ring is adapted to be fixed on the foot stand. The base is movably assembled on the limit ring along an axis. The base and the limit ring form a space. The spherical friction part is rotatably disposed in the space between the limit ring and the base. The pressing module is adapted to be fixed on the foot stand. The pressing module is configured on one side of the base along the axis, and pushes the base to a direction of the limit ring to compress the space formed by the base and the limit ring, so that the spherical friction part is in contact with the limit ring and the base. The spherical friction part is temporarily maintained at a specific angle by friction between the spherical friction part and the limit ring and friction between the spherical friction part and the base. A universal ball joint assembly is further provided.
