Floor Dressing Spreader with Resilient Element for Uniform Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spreaders for floor dressing materials do not efficiently and uniformly distribute the material over surfaces while allowing the user to remain standing, particularly on irregular surfaces.
Innovation Solution
A floor dressing spreader with an elongated handle secured to a back-up plate, featuring a resilient spreader element clamped between attachment plates, which extends downwardly for efficient and uniform distribution of dressing materials on concrete or asphalt surfaces, utilizing mechanical fasteners and a flexible rubber spreader for effective material application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional short-handled spreader is used, then the user can apply dressing material, but the user cannot remain in a standing position and must bend or kneel, causing physical strain and inefficiency
Solution Approach 1:
The invention transitions from a short-handled spreader requiring horizontal or bent-body operation to a long-handled spreader enabling vertical standing operation. The handle extends vertically along the back-up plate, allowing the user to stand upright and apply dressing material from a elevated position, fundamentally changing the operational dimension from ground-level to standing-height.
2Adaptability or versatility
If a rigid spreader element is used, then the structure is simple and strong, but the spreader cannot adapt to irregular surfaces and cannot provide uniform distribution of dressing material
Solution Approach 1:
The invention changes the physical parameter of the spreader element from rigid to resilient/flexible. The resilient spreader element can deform and conform to irregular surface contours, enabling uniform distribution of dressing material across both smooth and irregular surfaces while maintaining a relatively simple clamped structure between attachment plates.
3Ease of operation
If a long-handled spreader is used, then the user can remain standing, but the spreader becomes less stable and harder to control precisely
Solution Approach 1:
The invention applies weights to the lower end of the back-up plate to pre-establish downward force and stabilize the spreader element against the surface. This preliminary weighting action counteracts the potential instability from the long handle, ensuring the spreader maintains firm contact with the surface for precise control while allowing the user to stand.
4Manufacturing precision
If a non-resilient spreader element is used, then the material application is straightforward, but the spreader cannot facilitate uniform distribution over irregular surfaces
Solution Approach 1:
The invention changes the physical parameter of the spreader element from rigid to resilient/flexible. The resilient spreader element can deform and conform to irregular surface contours, enabling uniform distribution of dressing material across both smooth and irregular surfaces while maintaining a relatively simple clamped structure between attachment plates.
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
Enables efficient and uniform spreading of floor dressing materials over both smooth and irregular surfaces while allowing the user to maintain a standing position, ensuring effective material distribution and surface coverage.
Implementation Method 1
The resilient spreader preferably is of solid rubber material which is flexible to facilitate spreading the concrete or asphalt dressing material.

AI summary
A floor dressing spreader includes an elongated handle and an elongated back-up plate. The elongated handle is secured to the back-up plate and extends generally upwardly therefrom. Front and rear attachment plates are disposed adjacent lower portions of the back-up plate and a resilient flexible spreader element is clamped between an attachment plate and the back-up plate. The spreader extends downwardly beyond the lower edge of the back-up plate for spreading the concrete dressing material. The resilient spreader is preferably composed of a material which is flexible and resiliently deformable such as a rubber material.
