Flexible Roller System for Undulating Ground Aeration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soil aeration methods either leave soil plugs on the ground surface or create elevated regions, which are aesthetically undesirable and require additional maintenance, especially on undulating surfaces like putting greens.
Innovation Solution
A ground treatment system featuring a flexible roller system with rollers arranged in side-by-side positions and a flexible axle member that adjusts to match the terrain, coupled with an aeration apparatus that forms aeration pockets without removing soil plugs, allowing for simultaneous aeration and smoothing in a single pass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional coring tubes are used to aerate soil, then aeration pockets are formed, but soil plugs are removed and littered across the ground surface creating an undesirable appearance
Solution Approach 1:
The invention extracts and removes the harmful element (soil plugs) from the aeration process by using blades that cut and fracture soil without extracting plugs, thereby eliminating the littering problem while maintaining aeration effectiveness
Solution Approach 2:
The invention converts the potentially harmful effect of soil displacement into a beneficial outcome by using the displaced soil to backfill and seal the aeration pockets, preventing harmful factors like weed growth while maintaining soil structure
2Reliability
If aeration blades create aeration pockets, then soil aeration is achieved, but elevated regions or lips are created on the ground surface requiring additional maintenance
Solution Approach 1:
The invention converts the elevated soil material created during aeration into a beneficial sealing layer by having it backfill the aeration pockets, thereby eliminating the need for additional smoothing operations while maintaining effective aeration
Solution Approach 2:
The invention merges the aeration function with the smoothing function into a single operation, where the same blade system that creates aeration pockets also levels the surface by redistributing soil material
3Manufacturing precision
If a rigid roller system is used to smooth ground surface, then smoothing is provided, but the system cannot adapt to undulating terrain reducing effectiveness
Solution Approach 1:
The invention introduces dynamic adaptability to the roller system by allowing the axle to flex and the rollers to independently adjust their vertical positions, enabling the rigid smoothing surfaces to adapt to undulating terrain while maintaining smoothing effectiveness
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 system effectively aerates and smooths the ground surface, reducing maintenance needs and ensuring even terrain, particularly on undulating surfaces, by flexing to conform to ground undulations and eliminating the need for additional raking or mowing.
Implementation Method 1
a flexible axle member extending through the plurality of rollers such that the flexible axle member flexes in response to the plurality of rollers contacting an undulating portion of the ground surface
Implementation Method 2
an aeration apparatus coupled to the frame. The aeration apparatus may include a plurality of aeration tines that form aeration pockets in the ground surface when driven to penetrate the ground surface
