Vacuum Turntable for Ring Photography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ring photography methods using ring holders, wax, or adhesive dots often result in the holder or adhesive being captured in the image, and they can be difficult to clean without scratching the ring, limiting the ability to achieve clear and pure color backgrounds for 2D, 360-degree, or 3D photography.
Innovation Solution
A turntable equipped with a vacuum pump and motor that uses vacuum suction to stabilize and rotate a ring on a platter, combined with a light box providing a clear and pure color background, allowing for stable and rotating ring positioning without the need for traditional holders or adhesives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ring holders, wax, or adhesive dots are used to hold the ring, then the ring can be stably positioned for photography, but the holder or adhesive may be captured in the image and block part of the ring
Solution Approach 1:
The invention extracts and eliminates the traditional ring holder, wax, or adhesive dots from the system. Instead of using external holding materials, the ring is directly held by vacuum suction applied to the platter surface, removing the source of image obstruction while maintaining stable positioning
Solution Approach 2:
The invention replaces the mechanical holding system (ring holders, wax, adhesive dots) with a vacuum-based holding system. The vacuum pump creates negative pressure that holds the ring firmly on the platter without physical contact from holding materials, thus eliminating image obstruction
2Reliability
If wax or adhesive dots are used to hold the ring, then the ring can be positioned for photography, but cleaning the ring becomes difficult and may scratch the ring surface
Solution Approach 1:
The invention completely removes wax and adhesive dots from the positioning system. The ring is held solely by vacuum suction on the platter surface, leaving no residual materials on the ring that would require cleaning or risk scratching the surface
Solution Approach 2:
The vacuum holding system requires no additional cleaning steps. The ring is held without any adhesive materials, so no cleaning is needed at all. The system is self-cleaning in the sense that it leaves no residue requiring removal
3Ease of operation
If the ring is lied down on the table or platter for photography, then no holders or adhesives are needed, but the ring cannot stand upright for clear background photography
Solution Approach 1:
The invention uses vacuum pneumatics to hold the ring upright on the platter. The vacuum suction applied through the platter surface provides sufficient holding force to maintain the ring in a vertical standing position, enabling clear background photography while keeping the setup simple
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
Enables stable and rotating ring positioning for 2D, 360-degree, or 3D photography, avoiding image capture of holders or adhesives and providing a clean background, with the ability to automatically separate the ring from the background in 360-degree photography through controlled lighting.
Implementation Method 1
The suction hole provides a vacuum suction to enable the ring to stand on a carrying surface of the platter when the vacuum pump is turned on

AI summary
A turntable for ring photography is provided and includes a vacuum pump, a motor with a hollow shaft, an air hose connected between the vacuum pump and the hollow shaft, and a platter with a suction hole airtight communication with the hollow shaft. The suction hole provides a vacuum suction for ring standing when the vacuum pump is turned on. The platter brings the ring to rotate when the motor is turned on. A light box for ring photography is also provided and includes the foregoing turntable and a box. The box includes a base and the base has a top surface and an opening formed on the top surface. The vacuum pump is disposed under the top surface or outside the box. The motor is disposed under the top surface. The platter is embedded in the opening.
