Solution Overview
Problem
Existing window cleaning devices with fixedly positioned cleaning implements are limited in accessing non-uniformly shaped or hard-to-reach areas, as they do not allow for adjustable configurations.
Innovation Solution
A multi-positional window cleaning device featuring a handle with a pivoting assembly that allows the blade assembly to rotate and lock into multiple positions relative to the handle, enabling easier access to various angles and surfaces through a C-clip engagement mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning implement is fixedly positioned relative to the handle, then the device structure is simple, but the device cannot access non-uniformly shaped or hard-to-reach areas
Solution Approach 1:
The cleaning implement is made adjustable relative to the handle through a pivoting mechanism with multiple lockable positions. The blade assembly can be rotated about a pivot axis and locked at different angles using a locking mechanism, transforming the static fixed connection into a dynamic adjustable one, enabling adaptation to various surface geometries while maintaining structural simplicity
2Ease of operation
If the cleaning implement is fixedly positioned, then the device is easy to manufacture, but it limits ease of access to difficult to reach areas
Solution Approach 1:
The pivoting assembly with multiple lockable positions allows the cleaning implement to be adjusted to different angles and orientations, making it easier to access hard-to-reach areas. The mechanism uses simple mechanical components (pivot axis, locking mechanism) that can be easily manufactured and assembled, maintaining ease of production while significantly improving operational flexibility
3Adaptability or versatility
If the blade assembly can pivot to multiple positions, then accessibility is improved, but the device requires a locking mechanism increasing complexity
Solution Approach 1:
The pivoting assembly enables the blade to be positioned at multiple angles relative to the handle, providing adaptability to different cleaning scenarios. The locking mechanism, while adding some complexity, uses straightforward mechanical design with a pivot axis and locking components that can be easily manufactured and integrated, achieving a balance between multi-position capability and device complexity

AI summary
A multi-positional cleaning device includes a handle body having a first longitudinal axis, a head configured to receive a blade, and a pivoting assembly to rotate the blade. A plane extending through a center of the head, parallel to the blade. The head is rotatable about a pivot axis relative to the head. An orientation of the plane of the head remains constant relative to the longitudinal axis as the blade moves along the path of movement.
