Hand-Held Floor Cleaner with One-Sided Roller Brush for Edge Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held cleaning devices struggle to effectively clean edges and corners due to symmetrical roller brush mounting, which restricts access and applies uneven pressure, and require cumbersome device reorientation for directional changes.
Innovation Solution
A hand-held cleaning device with a one-sided roller brush mounting and a rotatable handle that can be locked in multiple positions, combined with a mechanism to reverse the direction of rotation when changing directions, ensuring even pressure and safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the roller brush is mounted between two pins (two-sided bearing), then the device structure is stable and symmetric, but the roller brush cannot be freely accessible on one side for edge cleaning
Solution Approach 1:
The patent applies asymmetry by mounting the roller brush on only one side (one-sided bearing) instead of between two pins. This asymmetric mounting allows the roller brush to be freely accessible on one side for effective edge and corner cleaning, while the device housing and drive mechanism are designed to accommodate this asymmetric configuration.
2Adaptability or versatility
If the roller brush is mounted on one side (asymmetrical mounting), then edge cleaning is enabled, but uniform pressure application via the handle becomes difficult
Solution Approach 1:
The patent introduces a rotatable handle that can be locked in multiple angular positions (0°, 45°, 90°, 135°, 180°). This adds a rotational dimension to the operation, allowing the user to adjust the handle orientation to achieve uniform pressure distribution on the roller brush while cleaning edges, thereby solving the pressure application problem associated with one-sided mounting.
3Adaptability or versatility
If the handle is rotatable for directional changes, then cleaning in different directions is enabled, but the device requires additional locking mechanism complexity
Solution Approach 1:
The patent implements a dynamic handle system that can rotate and be locked at multiple angular positions. The locking mechanism uses a simple detent or click system that engages at predetermined angles (0°, 45°, 90°, 135°, 180°), allowing the handle to transition between fixed positions while maintaining stability during operation. This dynamic design enables directional cleaning flexibility without excessive mechanical complexity.
4Adaptability or versatility
If a two-sided bearing is used for roller brush mounting, then pressure forces can be transmitted symmetrically, but the device cannot be used for wall cleaning where the roller brush needs free access
Solution Approach 1:
The patent employs asymmetric roller brush mounting on one side only, which sacrifices symmetric pressure transmission but enables wall and edge cleaning capabilities. The device housing and drive mechanism are specifically designed to accommodate this asymmetric configuration, with the roller brush positioned to allow free access to vertical surfaces and edges.
