A swivel base with a top and bottom member, utilizing a ball bearing for rotational coupling and a locking mechanism to secure the headform in stationary positions, allowing 180-degree rotation and locking functionality for stable support on stands like tripods or vice holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed mounting structure is used to support the headform, then stability is improved, but the ability to rotate the headform for 360-degree viewing is lost
Solution Approach 1:
The mounting structure transitions from a fixed state to a dynamic state by incorporating a swivel mechanism with ball bearings. The top member can rotate 360 degrees horizontally and tilt vertically, allowing the headform to be positioned at various angles while maintaining stability through friction and locking mechanisms.
Solution Approach 2:
The mounting structure allows changes in orientation parameters (horizontal rotation angle and vertical tilt angle) while maintaining stable support. The ball bearing mechanism enables continuous adjustment of these parameters, and friction provides stable positioning at desired angles.
2Adaptability or versatility
If a friction-based swivel mechanism is used to allow rotation, then viewing flexibility is improved, but unwanted rotation and stability are worsened
Solution Approach 1:
The friction force parameter is carefully controlled to provide sufficient resistance against unwanted rotation while allowing intentional rotation when force is applied. The normal force between contacting surfaces is designed to create appropriate friction levels for stable positioning.
Solution Approach 2:
Ball bearings are introduced as intermediary elements between the top member and base. These ball bearings reduce friction during intentional rotation while maintaining sufficient friction to prevent unwanted rotation, acting as a mediator between the two opposing requirements.
3Stability of the object's composition
If a complex locking mechanism is added to prevent rotation, then stability is improved, but device complexity increases
Solution Approach 1:
The mounting structure utilizes the friction inherent in the ball bearing mechanism and contact surfaces to provide self-locking capability. When the headform is tilted or rotated to a desired position, friction automatically maintains that position without requiring additional active locking components.
Solution Approach 2:
The mounting structure is divided into distinct functional segments: the ball bearing mechanism for rotation, the friction surfaces for positioning, and the mounting interfaces for attachment. This segmentation allows each component to perform its function simply without requiring complex integration.

Implementation Method 1
a ball bearing is secured around outer perimeter of the protrusion
Implementation Method 2
ball bearing secured around outer perimeter of the protrusion... mounting member is thus rotatably coupled to the top member via the ball bearing

AI summary
A swivel base for use with a training aid having a top member and a bottom member, the top member for receiving a training aid and the bottom member for receiving a holder or stand. The top member is coupled to a ball bearing and a mounting member fixedly coupled to the bottom member is rotatably coupled to the ball bearing to allow the top member to rotate relative to the bottom member. A locking mechanism which has a locking pin coupled to the bottom member secures the top member in one or more stationary positions.
