Pivoting Handle and Head for Stable Window Surface Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for treating target surfaces, such as windows and floors, face challenges in maintaining consistent pressure and control, especially when dealing with large or vertically oriented surfaces, leading to issues like chatter or separation from the surface.
Innovation Solution
A device with a handle and head mounted in a pivotal relationship, allowing for articulation relative to each other, which includes a pivot mechanism with convex and concave portions or a rack and pinion system to prevent separation and maintain contact with the surface, providing ergonomic convenience and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle and head are fixed in a planar relationship, then the device structure is simple, but it is difficult to maintain control and apply adequate pressure throughout the stroke, especially on vertical surfaces
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed planar relationship between handle and head into a dynamic pivotal relationship. The head can pivot relative to the handle around a pivot axis, allowing the device to adapt its configuration during operation. This enables the user to maintain adequate pressure on vertical surfaces throughout the stroke while preserving structural simplicity through a single degree of freedom mechanism.
2Adaptability or versatility
If the device uses a fixed handle arrangement, then the device structure is simple, but it cannot provide optimum ergonomics for all conditions, especially when transitioning between different stroke positions
Solution Approach 1:
The patent implements adaptability through a dynamic pivotal connection between handle and head. This single degree of freedom allows the device to adapt to different ergonomic requirements during the stroke, particularly when transitioning between overhead and lower positions on vertical surfaces. The mechanism provides versatility without complexity by allowing natural movement accommodation rather than requiring multiple fixed handle configurations.
3Ease of operation
If the device uses a pivot mechanism on the head, then ergonomic convenience is improved, but previous attempts have not proven entirely successful in maintaining control
Solution Approach 1:
The patent achieves both ergonomic convenience and control stability through a properly positioned pivot mechanism. The pivot axis is strategically located to allow the head to articulate relative to the handle, providing ergonomic flexibility. Simultaneously, the pivot connection maintains reliable control by keeping the head properly aligned with the target surface throughout the stroke, preventing chatter and separation that plagued previous designs.

AI summary
A device for treating a target, such as cleaning a window. The device has a handle and head, mounted in pivotal relationship to each other. When the head is placed in sliding, contacting relationship with the target surface the handle can pivot relative to the head for the ergonomic convenience of the user.
