Hinged Gimbal Ring Assembly for Rapid Tool Interchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gimbals require a lengthy process to swap out tools due to the need for disassembling and reassembling the ring around the tool, which is cumbersome and time-consuming, especially in applications like aircraft assembly where frequent tool changes are necessary.
Innovation Solution
A gimbal with a concentric ring assembly featuring an outer and inner ring with hinge and latch configurations that allow for easy opening and closing without interrupting the rotation of the inner ring, enabling quick tool changes without the need for separate screws or screwdrivers, and accommodating tools of various dimensions with deformable bumpers for secure grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ring is designed as a traditional screwed assembly, then the tool is securely held, but the tool change process becomes time-consuming and cumbersome
Solution Approach 1:
The ring assembly is divided into multiple segments that can be independently moved or detached. This segmentation allows the ring to open and close quickly around the tool without requiring complete disassembly of multiple screws, thereby reducing tool change time while maintaining structural integrity through the modular design
Solution Approach 2:
The ring assembly incorporates dynamic elements such as movable segments or flexible components that allow the ring to adapt its shape and size. This dynamic capability enables rapid opening and closing actions for quick tool changes while maintaining secure holding when closed, eliminating the need for complex fixed-structure assemblies
2Productivity
If the ring is disassembled for tool replacement, then the tool can be swapped, but the risk of foreign object debris increases
Solution Approach 1:
The fastening function is extracted from the traditional screw-based system and integrated into the ring structure itself through built-in latches, clips, or snap-fit mechanisms. This extraction eliminates loose screws and fasteners that could become foreign object debris, while maintaining secure tool holding and enabling quick tool changes through the integrated release mechanisms
3Reliability
If the ring requires hand coordination for reassembly, then the tool can be secured, but the operation becomes cumbersome and slow
Solution Approach 1:
The ring assembly incorporates self-aligning features such as guide pins, tapered surfaces, or keyed interfaces that automatically position the ring segments correctly during closure. This self-service capability eliminates the need for precise hand coordination during reassembly, allowing operators to simply close the ring and have it self-align and secure the tool reliably, thereby improving both ease of operation and reliability

AI summary
Systems and methods for switching tools in an enhanced ring assembly of a gimbal. One example is a gimbal that includes an outer ring and an inner ring. The outer ring is attached to an arm and includes a first hinge to open and close the outer ring, and also a first latch to fasten the outer ring in a closed position. The inner ring is rotatably supported within the outer ring and includes a second hinge to open and close the inner ring, and a second latch to fasten the inner ring in a closed position.
