Back-Worn Floor Fluid Dispenser With Adjustable Support Harness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor fluid dispensers lack a secure and ergonomic design that ensures the device remains positioned behind the user, particularly on slippery floors, and fails to provide support in case the user loses footing.
Innovation Solution
A fluid dispenser with a frame supported by wheels and a harness that attaches to the user's back, featuring a vertically adjustable mechanism, adjustable straps, and handles for secure attachment and movement, ensuring the device remains behind the user and provides support in case of loss of balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fluid dispenser is held in front of the user, then the user can easily access and control the device, but the device may interfere with the user's movement and cause instability on slippery floors
Solution Approach 1:
The patent inverts the conventional positioning of floor fluid dispensers by attaching the device to the user's back instead of having them hold it in front. This inversion moves the device from a position that interferes with movement to one that follows the user naturally, eliminating the trade-off between accessibility and stability.
2Ease of operation
If the fluid dispenser is designed to be lightweight and portable, then the user can move it easily, but the device cannot provide sufficient support if the user loses footing
Solution Approach 1:
The patent merges the fluid dispenser with a harness system that attaches to the user's back, combining two previously separate functions (fluid dispensing and user support) into a single integrated device. This allows the lightweight dispenser to provide both mobility and fall support simultaneously.
3Reliability
If the harness is designed to securely attach to the user's back, then the device remains positioned behind the user, but the harness may be uncomfortable or difficult to adjust for different users
Solution Approach 1:
The patent incorporates dynamic adjustment mechanisms into the harness, including vertical adjustment of the dispenser position and adjustable straps that can be customized for different body sizes. This allows the harness to adapt to various users while maintaining secure positioning of the device behind the user.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The fluid dispenser remains securely positioned behind the user, preventing falls and ensuring efficient fluid application, even on slippery floors, by attaching to the user's torso and providing support through the harness and wheels positioning the center of gravity within the wheel support.
Implementation Method 1
the vertically adjusting means including a vertically oriented rack and pinion for adjusting the vertical height of the harness by moving the harness along the rack
Implementation Method 2
the pinion attached to spring biased pinion lever for disengaging the pinion from a normally engaged position in the rack by depressing the pinion lever
Implementation Method 3
the frame includes at least three legs supported by wheels mounted on a bottom end of each leg such that the frame can roll along the surface of a floor
Implementation Method 4
a mop assembly is for fluidly communicating by gravity feed, the solution from the container to the mop head and bristles

AI summary
A fluid dispenser for application of solutions applied to floors is disclosed that includes a frame for supporting a container, wherein the frame includes legs supported by wheels mounted on a bottom end of each leg such that the frame can roll along the surface of a floor. The container is for holding solutions. A mop assembly is for fluidly communicating by gravity feed so that the solution from the container can be manually applied to the mop head. The dispenser further includes a harness attached to the frame for securely attaching the fluid dispenser to the back side lower torso of a person, wherein the harness includes a vertically adjusting mechanism for selectively adjusting the harness vertically according to the height of people.
