Hinged Tool Hook for One-Handed Left- or Right-Side Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool securing solutions, such as those for paint brushes, are inefficient and awkward to use, particularly for left-handed users, as they often require changing hand positions or are not easily movable between open and closed positions.
Innovation Solution
A removable hinged hook that can be attached to a tool, allowing it to be secured with a single hand and rotating to either side, facilitating use by both right- and left-handed individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed hanger is attached to one side of the brush handle, then the brush can be secured to the paint can, but left-handed users cannot access the hanger without changing hand position
Solution Approach 1:
The hanger is designed with a hinge mechanism that allows it to rotate between open and closed positions, and between different orientations. This dynamic capability enables the hanger to be accessed from either side of the brush handle, making it usable for both right-handed and left-handed painters without requiring hand position changes.
Solution Approach 2:
The hanger is divided into multiple segments or components including a main body, hinge mechanism, and attachment points. This segmentation allows the hanger to be flexible in its positioning and orientation, enabling it to adapt to different user needs and brush configurations.
2Reliability
If a non-removable hanger is used, then the brush can be secured, but the hanger cannot be easily moved or adjusted
Solution Approach 1:
The hinge mechanism provides controlled movement between fixed positions, allowing the hanger to be adjusted between open and closed states while maintaining secure attachment when in the closed position. This combines the reliability of a fixed attachment with the adaptability of adjustable positioning.
Solution Approach 2:
The hinge acts as an intermediary mechanism between the fixed brush handle and the movable hanger components. It provides a controlled connection that allows adjustment while maintaining secure attachment, bridging the gap between fixed and movable designs.
3Adaptability or versatility
If a complex hanger mechanism is used to provide full adjustability, then adaptability is improved, but the device becomes more complicated and difficult to operate
Solution Approach 1:
The hinge mechanism provides essential adjustability through a single rotational degree of freedom, allowing the hanger to move between open and closed positions without requiring complex multi-axis mechanisms. This simple dynamic element provides sufficient adaptability for different user needs.
Solution Approach 2:
The hanger design allows the user to easily manipulate the hinge mechanism with one hand to open or close the hanger as needed. The self-contained hinge design requires no additional tools or complex operations, making the adjustability feature simple to use.

AI summary
In some aspects, the removable hinged tool hook may include a device for coupling to a tool (such as a flexible elastic fabric band). Also, the removable hinged tool hook may include an inner member with an aperture therein. Furthermore, the removable hinged tool hook may include a hook member having an upper portion with an aperture therein, an elongated member extending downward from the upper portion, and at least one hook extension extending outward from a distal end of the elongated member. In addition, the removable hinged tool hook may include a hinge member for coupling the hook member and the inner member to the device for coupling to a tool, the hinge member passing sequentially through the aperture in the hook member and the aperture in the inner member and secured to the device for coupling to a tool.
