Adjustable Squeegee Blade Lock Assembly for Non-Uniform Surface Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeegee devices have fixedly positioned cleaning implements, limiting ease of access to non-uniformly shaped or difficult-to-reach areas.
Innovation Solution
A cleaning device with an adjustable configuration, featuring a handle, a channel member, a replaceable blade, and a lock assembly that allows the blade to be selectively rotated and locked in different positions relative to the handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cleaning implement is fixedly positioned relative to the handle, then the device structure is simple, but the ease of access to non-uniformly shaped or difficult-to-reach areas is limited
Solution Approach 1:
The cleaning implement is made adjustable relative to the handle through a locking mechanism that allows the user to change the position of the blade along the channel member. This dynamic adjustment capability enables the device to adapt to non-uniformly shaped surfaces and difficult-to-reach areas, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The device is divided into separable components including the handle, channel member, blade, and locking mechanism. This segmentation allows the cleaning implement to be repositioned and adjusted independently, providing flexibility for accessing difficult areas while maintaining a relatively simple overall structure.
2Ease of repair
If the blade is replaceably coupled to the channel member, then the ease of repair and maintenance is improved, but the device complexity increases
Solution Approach 1:
The blade is replaceably coupled to the channel member through a locking mechanism that allows easy attachment and detachment. This dynamic coupling enables straightforward blade replacement for maintenance purposes while using a relatively simple locking mechanism that does not significantly increase device complexity.

AI summary
A cleaning device is provided. The cleaning device includes a handle and a channel member operably coupled to the handle. A blade is replaceably coupled to the channel member. A lock assembly that includes an end cap, a lock switch member and a support member. The end cap is coupled to the channel member. The lock switch member is slidably coupled to the end cap, the lock switch member being movable between an unlocked, a locked and an extended position. The support member is moveably coupled to the end cap and having a support surface adjacent a surface of the blade, the support member having a ramp portion that is engagable by the lock switch member to translate the support surface into contact with the surface of the blade.
