Floor Machine Multi-Point Handle Attachment for Confined Space Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor machines lack versatility and accessibility for completing multiple tasks on various flooring surfaces, particularly in confined spaces, and they do not efficiently utilize treatment attachments.
Innovation Solution
A floor machine with multiple attachment bodies for securing the handle, allowing for different orientations and configurations, combined with a rolling attachment for side-to-side movement and a motor that revolves the treatment attachment in two directions, enhancing accessibility and attachment longevity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the floor machine uses a single handle attachment point, then the structure is simple, but the accessibility to confined spaces is limited
Solution Approach 1:
The handle attachment system is segmented into multiple attachment points (first and second attachment points) located at different positions on the floor machine. This allows the handle to be attached at different locations depending on the working conditions, enabling access to confined spaces while maintaining structural simplicity through modular attachment design
Solution Approach 2:
The handle attachment position is made dynamic and adjustable rather than fixed. The user can detach and reattach the handle at different attachment points based on the specific task and space constraints, providing adaptability without permanently complicating the device structure
2Duration of action of moving object
If the treatment attachment revolves in one direction only, then the mechanism is simple, but the attachment lifespan is reduced
Solution Approach 1:
The treatment attachment revolution mechanism implements periodic direction reversal, automatically alternating between first and second directions during operation. This periodic action distributes wear evenly across the attachment surface, extending its service life without requiring a complex dual-directional control system
Solution Approach 2:
The revolution mechanism automatically alternates directions without user intervention, using the operational motion itself to achieve balanced wear distribution. The system serves itself by converting the natural back-and-forth movement into a wear-balancing mechanism
3Adaptability or versatility
If the floor machine has fixed orientation, then the structure is simple, but the versatility for different surface types is limited
Solution Approach 1:
The floor machine is designed with universal attachment points that accommodate different handle configurations and treatment attachments suitable for various surface types (tile, granite, hardwood, stone, carpet, stairs, grout, concrete). This multi-functionality is achieved through standardized attachment interfaces rather than complex reconfiguration mechanisms

AI summary
The floor machine provides an attachment system capable of securing a handle to the floor machine at multiple locations. A handle storing a power source, such as batteries, attaches to the housing to power the motor. A housing of the floor machine provides two attachment bodies located on the exterior of two different walls of the housing. By securing the handle to the different attachment points, the user can configure the footprint of the floor machine to increase the user's access to narrower and/or smaller confined areas. The power source electrically connects to the motor at a powering location separate from the attachment location of the handle to the housing. The distinct attachment location and powering locations enables different attachments of the handle to the housing.
