Pivoting Tool Base Assembly With Locking Ring Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many tools are large and unwieldy, making it difficult to maneuver and maintain them in the appropriate position for tasks, necessitating a base assembly that can accommodate tools in multiple positions and facilitate their movement.
Innovation Solution
A base assembly with a pivot pin system, including first and second locking rings and a dowel pin, allows tools to be removably and adjustably positioned, secured, and rotated, using a handle for manipulation, with a clip or tether for secure storage when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a tool is made large for heavy-duty applications, then it can handle more demanding tasks, but it becomes unwieldy and difficult to maneuver into appropriate positions
Solution Approach 1:
The tool system is segmented into two parts: the heavy-duty tool itself and a separate base assembly with multiple positioning options. The base assembly includes vertical and horizontal positioning mechanisms that allow the tool to be oriented in different directions (upside down, sideways, at various angles), separating the tool's weight-bearing capacity from its positioning flexibility.
Solution Approach 2:
The base assembly acts as an intermediary between the operator and the heavy tool. It provides the positioning and orientation capabilities that would be difficult to achieve by manually maneuvering the heavy tool directly, while the tool remains securely attached to the base through the pivot pin and locking mechanism.
2Stability of the object's composition
If a tool is securely fixed in position, then it remains stable during operation, but it cannot be easily repositioned or adjusted
Solution Approach 1:
The locking mechanism transitions between static (locked) and dynamic (unlocked) states. The spring-loaded locking ring with cam engagement provides a stable locked state during operation, while the release mechanism allows quick transition to an unlocked state for repositioning. The system dynamically switches between stability and adjustability based on operational needs.
Solution Approach 2:
The system changes the positional parameters of the tool by allowing rotation around the pivot pin axis. The base assembly provides multiple discrete positioning options (vertical, horizontal, angled positions) by changing the orientation parameter while maintaining secure attachment through the locking mechanism.
3Device complexity
If a single locking mechanism is used, then the device complexity is reduced, but the reliability of tool positioning may be insufficient
Solution Approach 1:
The positioning function is extracted from the tool itself and placed in the base assembly. The pivot pin and locking mechanism are separate components that can be independently optimized. The locking ring with cam engagement is a simple mechanism that reliably prevents rotation, while the overall positioning reliability is enhanced by the separate positioning of the base assembly itself.

AI summary
A base assembly removably and adjustably receives a tool and includes a base and a wall extending outwardly from the base. First and second openings are disposed in the wall. First and second cutouts are disposed in the wall to receive the tool. A pivot pin is removably received by the first and second openings. The tool is removably disposed on the pivot pin. A locking ring is disposed on the pivot pin. The locking ring is in a locked position to prevent movement of the pivot pin and in an unlocked position to allow movement of the pivot pin, thereby allowing the tool to be easily moved between positions and securely locked in a desired position.
