Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cleaning element is rigidly fixed to the handle, then structural simplicity is maintained, but maneuverability and orientation flexibility are limited
Solution Approach 1:
The cleaning element is made dynamically adjustable through a mounting assembly that allows rotation about two orthogonal axes (first and second axes). The cleaning element can be positioned at multiple orientations and locked into place, transforming a static rigid connection into a dynamic adjustable one that provides flexibility while maintaining structural integrity.
Solution Approach 2:
The mounting assembly is segmented into multiple components including a mounting bracket, adapter, and locking mechanism. This segmentation allows each component to perform a specific function (positioning, rotation, locking) and enables independent adjustment of the cleaning element's orientation without affecting the entire structure.
2Ease of operation
If a rigid fluid conduit is used, then structural stability is maintained, but flexibility in positioning and maneuverability are reduced
Solution Approach 1:
A flexible conduit is used to deliver fluid from the handle to the cleaning element. This flexible conduit can bend and flex to accommodate the various positions and orientations of the cleaning element while maintaining fluid delivery, replacing a rigid conduit that would restrict movement and positioning flexibility.
3Measurement precision
If multiple adjustment mechanisms are added for precise orientation, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The adjustment and locking functions are extracted into a separate mounting assembly that is coupled between the handle and cleaning element. This mounting assembly includes a locking mechanism with engagement features that can be selectively engaged to lock the cleaning element at desired orientations, separating the adjustment function from the main structural components.
4Adaptability or versatility
If the cleaning element is made adjustable and movable, then cleaning versatility is improved, but structural stability may be compromised
Solution Approach 1:
The system transitions from a static rigid connection to a dynamic adjustable connection that provides both movement capability and stability. The locking mechanism allows the cleaning element to be securely locked at selected positions, providing structural stability when needed while maintaining adjustability for versatility.
Solution Approach 2:
The mounting assembly is designed to accommodate and support the cleaning element in various positions before locking, ensuring structural stability is maintained throughout the adjustment range. The engagement features are designed to smoothly engage and lock, preventing sudden shifts or instability during operation.

AI summary
A cleaning device (20) includes a handle (22) having a longitudinal axis, a cleaning element (24) movably coupled to the handle (22), and a flexible conduit (140) fluidly connectable to the cleaning element (24). The flexible conduit (140) is positionable within an interior of the handle (22). The cleaning element (24) is movable relative to the handle (22) about a first axis (R1) and a second axis (R2) when the flexible conduit (140) is fluidly coupled to the cleaning element (24). The first axis (R1) and the second axis (R2) are arranged at an angle relative to the longitudinal axis.
