Rotating Workpiece Turntable for Even Cabinet Painting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for refinishing or painting cabinet elements, such as drawers and doors, are time-consuming and require careful positioning to ensure even paint distribution, lacking the ability to easily move or reorient the articles being painted.
Innovation Solution
A workpiece turntable with a rotatable base and height-adjustable support elements, featuring elastomer support fingers that allow for secure holding and easy rotation of workpieces, facilitating even painting and reducing user strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional methods (sawhorses, paint stands) are used to support workpieces, then the workpiece can be supported for painting, but the painter must carefully angle the spray gun at all portions to achieve even paint distribution and the workpiece cannot be easily moved or re-oriented
Solution Approach 1:
The patent applies the dynamics principle by making the support structure movable and rotatable. The turntable module allows the workpiece to be rotated to different orientations, and the height-adjustable support elements allow the workpiece to be positioned at different angles and heights, enabling easy movement and re-orientation while maintaining even paint distribution through controlled positioning.
Solution Approach 2:
The patent applies the dimensionality change principle by adding rotational and height-adjustment capabilities to the support system. The turntable provides rotational movement (adding a rotational dimension), and the height-adjustable support elements add vertical positioning capability, transforming the static 2D support surface into a dynamically adjustable 3D positioning system that facilitates even painting from multiple angles.
2Productivity
If the painter manually positions and repositions the workpiece on conventional supports, then the workpiece can be painted, but the process is time-consuming and tiring
Solution Approach 1:
The dynamics principle improves productivity by enabling the workpiece to be easily rotated and repositioned through the turntable mechanism and height-adjustable support elements, reducing the physical effort required compared to manually handling workpieces on static supports, thereby decreasing user fatigue while increasing painting efficiency.
Solution Approach 2:
The self-service principle is applied through the self-supporting nature of the turntable module with its wire frame and support elements that automatically hold the workpiece in position without requiring constant manual adjustment, allowing the system to serve itself in maintaining workpiece positioning during the painting process.

AI summary
A workpiece turntable comprises a turntable module and an attachable floor-engaging support. The floor-engaging support is preferably height adjustable. The turntable module comprises a rotatable base mounted on a stationary base; a wire frame mounted over the rotatable base; a first set of support elements extending from the wire frame having a first height relative to the rotatable base; and a second set of support elements extending from the wire frame having a second height relative to the rotatable base. Each one of the support elements includes a respective support finger that can be made of an elastomer such rubber, silicone, or urethane.
