Ring Holder Fixture With Rotatable Mandrel and Vertical Tool Mounts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ring holding fixtures are limited in versatility, particularly lacking in ability to accommodate vertical orientations and integration with common jeweler's tools like scribes, vises, knurling tools, and pitch cups, which hampers access and functionality during various tasks.
Innovation Solution
A ring holder base designed for both horizontal and vertical use, featuring a rotatable mandrel, adjustable tool mounts, and integrated tool adapters that allow for secure mounting of various tools in different orientations, including a vise and pitch cup, enhancing accessibility and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If opposed mandrels are used to hold the ring, then stability and control during engraving is improved, but access to the ring at certain angles is hampered
Solution Approach 1:
The patent employs a rotatable mandrel assembly that can be rotated to different angular positions, allowing the ring to be accessed from various angles while maintaining stable holding. The mandrel rotation mechanism enables dynamic repositioning of the ring without compromising the stability provided by the opposed mandrel configuration.
2Ease of operation
If a single-mandrel design is used, then access to the ring is improved, but versatility in use and suitability for common jeweler's accessories is reduced
Solution Approach 1:
The patent integrates multiple tool mounting capabilities into the fixture base, including provisions for scribes, vises, knurling tools, and pitch cups. The angled mounting faces and multiple attachment points enable the single-mandrel design to accommodate various jeweler's accessories, achieving versatility without sacrificing access to the ring.
3Device complexity
If the fixture is designed for horizontal use only, then structural simplicity is maintained, but adaptability to vertical and other orientations is lost
Solution Approach 1:
The patent incorporates angled mounting faces and a rotatable mandrel assembly that enable the fixture to operate effectively in multiple orientations including horizontal, vertical, and intermediate positions. The geometric design of the mounting surfaces and rotation mechanism allows the same structure to adapt to different spatial configurations without requiring separate fixtures for each orientation.

AI summary
A ring holder system comprising a ring holder base with a body that can be oriented horizontally and vertically on a flat work surface. The base includes a single mandrel extending from a front end face of the base, angled upper tool mounting surfaces circumferentially offset from a top surface of the base, and a flat rear end face for resting the base in a vertical work orientation on a flat surface. A horizontal tool adapter mount is configured to be removably mounted on one of the angled upper tool mounting surfaces, and a vertical tool adapter is configured to be mounted on the bottom surface of the base in the vertical work orientation. The mandrel includes a threaded mounting ring at an inner end of the mandrel adjacent the front end face of the base for mounting accessories such as vises and pitch cups rotatably on the mandrel in the vertical work orientation.
