Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing squeegee devices require users to stoop or kneel when cleaning lower surfaces, such as windows or glass shower enclosures, limiting convenience and efficiency.
Innovation Solution
A telescoping and reverse-angle adjustable squeegee with a spring-loaded locking mechanism and rotatable base, allowing the squeegee head to be oriented in a reverse angular fashion and adjustable between 110° to 180°, enabling upward motion without the need for bending or kneeling, and constructed from durable materials like aluminum or plastic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the squeegee head is fixed at a standard angle, then the structure is simple, but the user must stoop or kneel to clean lower surfaces
Solution Approach 1:
The squeegee head is made rotatable relative to the handle, allowing the angle to be dynamically adjusted between fixed positions (e.g., 0° to 180°). This enables users to adapt the squeegee angle to different cleaning scenarios, including lower surfaces, without permanently complicating the basic structure.
Solution Approach 2:
The squeegee is divided into separable components: a handle and a rotatably connected head assembly. This segmentation allows independent optimization of each part and enables the head to rotate relative to the handle, providing angular adjustment capability while maintaining structural simplicity through modular design.
2Length of moving object
If the squeegee handle is extended to reach lower surfaces, then the cleaning range is improved, but the device becomes harder to control
Solution Approach 1:
The handle incorporates telescoping sections that can extend and retract. This dynamic length adjustment allows users to extend the handle for reaching lower surfaces and retract it for better control during overhead or close-range cleaning tasks.
Solution Approach 2:
The handle is segmented into multiple telescoping sections that can independently extend or retract. This segmentation provides flexible length adjustment while maintaining a compact form when retracted, balancing reach capability with control precision.
3Adaptability or versatility
If the squeegee head is made rotatable for angle adjustment, then the cleaning versatility is improved, but the locking mechanism complexity increases
Solution Approach 1:
The rotatable head incorporates a spring-loaded detent mechanism that automatically engages with recesses in the rotating base, providing self-locking at fixed angular positions without requiring manual intervention. This self-service locking mechanism maintains versatility while minimizing operational complexity.
Solution Approach 2:
The locking mechanism uses discrete angular positions (fixed parameters) rather than continuous adjustment. The spring-loaded detent engages with specifically positioned recesses to lock the head at predetermined angles, simplifying the mechanism compared to continuous adjustment systems while maintaining adequate versatility.

AI summary
An adjustable hand-held squeegee device with reverse angle head adjustment. An elongated handle can include either a single elongated member or any plurality of members configured in telescoping fashion. A head includes a rotatable base portion supported at a forward end of the handle. A spring biased locking mechanism is integrated into the handle in proximity to the rotatable base and includes a forward projection engaging a first recess of the rotatable base in a first position. Upon retracting the mechanism via a projecting trigger portion, the rotatable base is rotated to align a second circumferentially offset recess so that, and upon releasing the trigger, the squeegee head is oriented in a reverse angular fashion relative to the handle.
