Patent CN110313766B
Updated November 6, 2026Automated Rotating Display Stand for Porcelain Bowls
Standard static shelves risk tipping fragile ceramics and offer limited viewing angles. Automated rotating displays provide 360-degree visibility but often lack proper securing mechanisms for irregular shapes. This design solves that by integrating a pneumatic lift with dual conveyor-driven rotation and multi-point clamping. The bowl is raised into view, held firmly by curved support plates, and rotated smoothly within a protective glass case. It ensures the item remains stable while offering customers a full look at the craftsmanship.

The problem
Retailers displaying high-value ceramics face two main challenges: visibility and security. Static shelves allow customers to see only one side of an ornate bowl, missing the detailed artwork on the back. While rotating platforms exist, they often rely on simple friction drives that can slip under load or vibrate excessively, causing fragile items to wobble or fall. Furthermore, many automated displays lack robust securing mechanisms for irregularly shaped objects like deep bowls. If the power cuts out or the motor stalls, there is no physical backup to keep the item centered. This risk limits the use of automated rotators for premium products where breakage would result in significant financial loss and brand damage.
The solution
The patent describes a display stand that integrates lifting, rotation, and clamping into a single enclosed unit. The core structure consists of a casing with a glass cover on top. Inside, a lifting plate holds the exhibition device. This plate is moved vertically by a first rodless cylinder supported by four first cylinders. For rotation, a driving piece turns a first transmission shaft, which connects via rollers and a first conveyor belt to a second transmission shaft. A second conveyor belt runs parallel to the first, both attached to vertical plates that carry the clamping assemblies. The exhibition device itself uses multiple support plates with curved surfaces and inclined grooves to cradle the bowl. Additional protection devices on the vertical plates include sliding blocks and springs that engage if the bowl shifts laterally.
Who it is for
- Specialty ceramics retailers who need to showcase intricate patterns on all sides of expensive bowls without manual handling risks.
- Museum gift shops and cultural centers displaying replica artifacts where static views limit customer engagement and sales conversion.
- High-end home decor brands using interactive displays in flagship stores to demonstrate product quality and craftsmanship dynamically.
- Trade show exhibitors requiring self-contained, automated units that draw attention to specific hero products amidst busy booth traffic.
How it works
The main parts
| No. | Part | What it does |
|---|---|---|
| 1 | Casing | Main body housing the mechanism and supporting the glass cover. |
| 2, 3 | Lift Cylinders | Rodless and standard cylinders that raise the display platform. |
| 4 | Lifting Plate | Base surface carrying the bowl and clamping devices. |
| 6, 7 | Transmission Shafts | Drive the rotation system; connected by belts. |
| 9, 210 | Conveyor Belts | Transfer motion from shafts to the vertical plates. |
| 11, 12 | Vertical Plates | Mounting surfaces for clamps and protection devices. |
| 20, 21 | Support Plates | Hold the bowl; feature curved arcs and grooves. |
| 22, 28 | Arc Plates | Curved surfaces that cradle the bowl’s rim and base. |

Operating steps
- Placement: The bowl is placed onto the lifting plate, nestled between the first and second support plates.
- Clamping: The arc-shaped plates and inclined grooves align with the bowl’s curvature, securing it laterally.
- Lifting: The first rodless cylinder activates, raising the entire assembly into the visible space under the glass cover.
- Rotation: The driving piece rotates the first transmission shaft. Through the first conveyor belt, this motion turns the second shaft and the associated vertical plates, causing the bowl to spin.
- Safety Engagement: If lateral shift occurs, the spring-loaded protection blocks on the vertical plates engage to prevent dropping.
Applications

What the claims cover, in plain language
Claim 1 defines a display stand comprising a casing with a glass cover. Inside, a lifting plate is raised by a first rodless cylinder and four first cylinders. An exhibition device sits on the plate. Rotation is achieved via a driving piece connected to a first transmission shaft, linked by a first conveyor belt to a second transmission shaft. Vertical plates attached to these belts carry clamping devices. Protection devices are mounted on the vertical plates. The clamping system uses support plates with curved arcs and inclined grooves to secure the bowl. Secondary cylinders adjust a third clamping assembly.
Claim 2 specifies the exhibition device includes first and second support plates with penetrating clamping grooves. Arc-shaped plates are fixed to the front and rear ends of the support plates, featuring inner inclined grooves to guide the bowl.
Claims 3-5 detail additional moving plates and third support plates with further clamping grooves and arc plates, creating a multi-stage securing mechanism for the bowl’s position.
Claims 6-9 describe the protection devices, which include a moving space in the vertical plate, a sliding plate with extension springs, and limiting blocks with straight plates and lifting springs that engage to prevent lateral displacement.
This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.
What this means for US production
This patent was filed in China and is currently in force. Making or selling this specific design in China requires the owner’s permission. The public record shows no US or other foreign counterpart.

Production notes
Tooling and process
The structural frame likely requires sheet metal fabrication for the casing and supports. Transmission shafts and rollers are typically made from steel or aluminum stock. Clamping plates and protection covers usually involve injection molding or acrylic forming depending on material choice. Assembly involves screws and rivets for permanent joints, with slot-fit for modular clamp adjustments.
Cost drivers
Sheet thickness typically affects the rigidity and weight of the casing. Surface finish quality impacts aesthetics and corrosion resistance. The number of parts in the clamping and protection systems increases assembly time and inventory complexity. Packaging volume is critical due to the large footprint of the glass cover and frame.
Prototyping path
Typically, start with a 3D model and load check to verify cylinder capacity. Create a cut and bent sample of the main frame to test fitment. Perform a load test with weighted dummy bowls to check stability during rotation. Conduct a flat-pack trial if shipping efficiency is prioritized. Finalize with tooling for mass production parts.
What we would change before tooling
We would likely simplify the shaft and bearing alignment tolerances to reduce assembly errors. Consider replacing some spring fatigue prone components with harder materials. Review the wall thickness and joint design of the acrylic cover to prevent acrylic cracking during thermal expansion.
Common failure points
Insufficient load capacity is a risk if cylinders are undersized for the glass and bowl weight. Tipping is a likely risk if the center of gravity shifts during rotation. Coating scratches from improper handling of sheet metal. Motor mount cracking due to vibration resonance.

Frequently asked questions
How does the bowl stay secure during rotation?
The design uses multiple clamping devices with curved arc plates and inclined grooves. These features cradle the bowl’s shape, holding it firmly in place even when the platform lifts or spins.
Can it handle different bowl sizes?
Yes. The clamping plates and vertical protection devices are adjustable. You can customize the spacing and curvature of the support plates to fit various diameters and depths of porcelain bowls.
Is the noise level low enough for retail stores?
The patent describes a belt-driven rotation system. Belts generally operate more quietly than gears. Noise levels depend on motor selection and frame damping, which can be tuned during the design phase.
What happens if the power goes out?
The protection devices include spring-loaded blocks. While the primary function is to stop lateral shifting during operation, the mechanical clamps physically hold the bowl, preventing it from falling immediately upon power loss.
Can I add lighting inside the case?
Yes. The glass cover provides ample space for integrated LED strips. Lighting enhances the visibility of the porcelain details and attracts customer attention.
How much weight can the lift handle?
The patent does not specify a maximum load rating. Capacity depends on the selected pneumatic cylinders and structural strength of the lifting plate, which are determined during engineering design.
Can this design be made and sold in the US?
The patent is in force in China, but the public record shows no US counterpart. Therefore, it does not restrict manufacturing or selling this design in the United States. However, you should still perform a freedom-to-operate search to ensure no other US patents cover similar automated display mechanisms.
