Scoop With Variable Slat Spacing For Particle Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scoops are ineffective in efficiently separating heterogeneously sized particulate matter due to uniform spacing between slats, which fails to differentiate between smaller and larger particles effectively.
Innovation Solution
A scoop design with spaced apart slats that are closer together near the front end and progressively farther apart towards the back end, allowing smaller particles to pass through the narrower spaces first and larger particles to pass through the wider spaces, with a curvilinear base and varying slat depths to enhance separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If uniform spacing between slats is used, then manufacturing simplicity is maintained, but separation effectiveness of heterogeneously sized particulate matter deteriorates
Solution Approach 1:
The slat spacing is configured with varying intervals along the length of the scoop, creating different local qualities for separation. The narrower spacing at the front end and wider spacing toward the back end allows the scoop to effectively separate heterogeneously sized particulate matter by size, with smaller particles passing through front slats and larger particles passing through rear slats.
2Manufacturing precision
If slats are spaced closer together near the front end, then smaller particles are effectively separated, but the area for larger particle passage is reduced
Solution Approach 1:
The scoop is segmented into multiple zones with different slat spacing configurations. The front portion has narrower spacing for small particle separation, while the rear portion has wider spacing for large particle passage. This segmentation allows each zone to perform its specific function optimally without compromising the other.
Solution Approach 2:
The solution extends the separation function into the longitudinal dimension of the scoop by varying slat spacing along its length. Instead of using a single uniform spacing, the invention creates a gradient of spacing intervals that progresses from narrow at the front to wide at the rear, effectively using the length dimension to solve the area constraint problem.
3Quantity of substance
If slats are spaced farther apart towards the back end, then larger particles can pass through, but separation precision for smaller particles is reduced
Solution Approach 1:
Each section of the scoop maintains its local quality appropriate for its function: the front section with narrower spacing provides precise separation for smaller particles, while the rear section with wider spacing facilitates passage of larger particles. The transition between these zones is designed to maintain overall separation precision while enabling larger particle passage.
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
Effectively separates smaller from larger particulate matter by allowing smaller particles to fall through the narrower spaces near the front end and larger particles to fall through the wider spaces near the back end, improving the scooping efficiency.
Implementation Method 1
dipping the scoop (starting with the extreme opposite end of the scoop towards the handle) into heterogeneously sized particulate matter causes smaller pieces of the heterogeneously sized particulate matter to fall between the plurality of spaced apart slats before larger pieces of the heterogeneously sized particulate matter fall through the wider spaced apart slats

AI summary
A scoop has a handle and curvilinear base such that the scoop is narrower at an extreme end and deeper at a back end, the back end meeting a handle. A front most region of the device meets the top side of the device in some embodiments, such that side walls, the top side, and the bottom side join at a front end. The bottom side of the base has a plurality of spaced apart slats with portals therebetween. The slats are closer together near the front side than the back side, becoming progressively more spaced apart. In this manner, a smallest size particulate matter falls through the slats at the front end of the device while progressively larger particulate matter falls through towards the back end of the device in proportion to the increasing space between the slats.
