Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jiggering and jollying systems in pottery are cumbersome and lack rigidity, leading to irregularities in contoured surfaces and inefficiencies in shaping processes.
Innovation Solution
A shaping system that includes a support assembly and template holder, secured to a pottery wheel, allowing a template to remain stationary relative to a rotating workpiece, using a carousel base and ring bearing for stability and adjustable depth stops for precise contouring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a template is secured to a fixture and the fixture is positioned and locked in place, then the template can be held stationary, but the system becomes cumbersome and lacks rigidity to maintain constant template position
Solution Approach 1:
The patent combines the template holder and fixture into a single integrated assembly that rotates as one unit with the pottery wheel. The template holder is secured to the fixture which is coupled to the pottery wheel, creating a unified structure that eliminates the need for separate positioning and locking steps while maintaining template stability throughout the shaping process.
Solution Approach 2:
The patent introduces a rotary coupling mechanism that allows the template holder to rotate with the pottery wheel while maintaining the template in a stationary position relative to the workpiece. This dynamic design enables the template to remain stable during rotation without requiring complex locking mechanisms, as the entire assembly rotates together as a single unit.
2Stability of the object's composition
If multiple steps are performed to secure template to fixture and position fixture, then template can be held in place, but the process becomes time-consuming and inefficient
Solution Approach 1:
The template holder is pre-secured to the fixture during manufacturing, and the fixture is pre-coupled to the pottery wheel. This preliminary assembly eliminates the need for multiple setup steps during actual use, as the template is already positioned and secured before the shaping process begins, significantly reducing setup time while maintaining stability.
Solution Approach 2:
By integrating the template holder, fixture, and pottery wheel coupling into a single unified assembly, the patent eliminates the need for separate positioning and securing operations. The template is secured to the fixture which is coupled to the pottery wheel as one integrated unit, allowing for rapid setup while maintaining template stability throughout the shaping process.
3Manufacturing precision
If known jiggering and jollying systems are used, then templates can be applied to workpieces, but the systems lack rigidity to maintain constant template position producing irregularities in contoured surface
Solution Approach 1:
The patent employs a rotary coupling mechanism that dynamically adapts to the rotation of the pottery wheel while maintaining template stability. The template holder rotates with the wheel but keeps the template in a fixed position relative to the workpiece, ensuring consistent contouring results throughout the shaping process without the irregularities caused by rigid, non-rotating fixtures.
Solution Approach 2:
The integration of the template holder, fixture, and pottery wheel coupling into a single unified assembly ensures that the template maintains a constant, stable position relative to the workpiece throughout rotation. This merged structure eliminates the position variations and irregularities that occur in separate, non-integrated systems, producing consistent contoured surfaces.

AI summary
A system may be used with a pottery wheel to facilitate the shaping of a workpiece. The system may have a support assembly coupled to a rotatable wheel of the pottery wheel, and a template holder that holds a template relative to the wheel. The support assembly may have a rotary coupling to which the template holder is coupled; thus, the template holder may be used to keep the template stationary as the wheel, workpiece, and support assembly rotate. The template may be used for jiggering and/or jollying, and may have a plate with a shaping surface that contacts the workpiece during relative rotation to provide the desired contour. The template may have a plate that is insertable into a slot of the template; the template may be retained by the template holder at multiple displacements from the rotatable wheel.
