Adjustable Handle With Rotating Grip Positioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hose handles are often not ergonomically designed, leading to user discomfort and fatigue during extended use, as they fail to accommodate individual grip preferences, prioritizing hose and nozzle design over handle functionality.
Innovation Solution
An adjustable handle with a grip position adjuster and a nozzle that allows for multiple grip configurations and spray modes, featuring a connecting member, grip, and valve system for ergonomic comfort and fluid control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed grip position is used in conventional hose handles, then the structure is simple and easy to manufacture, but user comfort and ergonomics deteriorate due to inability to accommodate different grip preferences
Solution Approach 1:
The grip position is made adjustable rather than fixed, allowing the grip to rotate between multiple positions (e.g., horizontal and vertical orientations). This dynamic adjustment capability enables users to customize the handle configuration to their ergonomic preferences while maintaining a relatively simple overall structure through controlled movement mechanisms.
Solution Approach 2:
The handle is divided into separable components including the grip, body, and connecting members that can rotate relative to each other. This segmentation allows independent adjustment of the grip position without redesigning the entire handle structure, balancing customization needs with manufacturing simplicity.
2Adaptability or versatility
If multiple grip positions are made adjustable, then user comfort and adaptability improve, but device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
A rotational mechanism is incorporated that allows the grip to rotate between multiple predetermined positions and lock in place. This dynamic system provides multiple grip configurations (e.g., different orientations of the grip relative to the body) using a single adjustment mechanism rather than multiple separate mechanisms, thereby achieving versatility while controlling complexity.
Solution Approach 2:
The rotational adjustment mechanism serves multiple functions: it enables the grip to assume different orientations, locks in selected positions, and can be operated through a single interface (such as a button or knob). This multi-functionality reduces the need for separate mechanisms for each adjustment capability, balancing versatility with simplicity.
3Ease of manufacture
If the focus is on hose and nozzle design, then manufacturing resources are optimized for those components, but handle ergonomics and user experience deteriorate
Solution Approach 1:
The handle is designed as a separate, modular assembly with the grip, body, and connecting members that can be manufactured independently and then assembled. This segmentation allows manufacturing processes to be optimized for each component (including the handle) while maintaining overall integration, ensuring that ergonomic considerations for the handle are addressed without sacrificing manufacturing efficiency.
Solution Approach 2:
The handle incorporates adjustable and rotatable components that can be manufactured using standard processes and then assembled with appropriate fastening mechanisms. This approach allows the handle to achieve ergonomic versatility through assembly rather than complex monolithic manufacturing, balancing ease of manufacture with operational excellence.

AI summary
An adjustable handle that may be used with, e.g., a hose, the adjustable handle including a body having a connecting member extending therefrom, a first end, a second end, and an interior channel extending from the first end to the second end; a grip having a central opening and a cavity for receiving the connecting member of the body to connect the body with the grip; and a grip position adjuster at least partially disposed in the cavity of the grip, the grip position adjuster including a button extending into the central opening of the grip, where adjustment of the grip position adjuster by depressing of the button of the grip position adjuster permits rotational movement of the grip from being locked a first position to being locked in a second position.
