Adjustable Guided Rake Apparatus for Surface Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grading rakes lack adjustability and versatility, requiring users to rely on judgment for accuracy and necessitating multiple tools for different grading situations, which is costly and inefficient.
Innovation Solution
An adjustable guided rake apparatus with a grading rake head, guide track, adjustable rake guides, and a height adjuster allows for precise leveling of a primary surface relative to a secondary surface, enabling user-specified standards without the need for complex checks or multiple tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed grading rake is used, then the device is simple and inexpensive, but it lacks adaptability for different grading situations and surfaces
Solution Approach 1:
The rake guide is made adjustable along the guide track, allowing dynamic repositioning to accommodate different grading situations and surface requirements. The height adjuster enables continuous modification of the rake guide position, transforming a static tool into a dynamic one that adapts to various working conditions.
Solution Approach 2:
The adjustable rake guide system allows a single grading rake to perform multiple grading functions by repositioning the rake guide to different locations along the guide track, eliminating the need for multiple specialized rakes for different grading situations.
2Adaptability or versatility
If multiple grading rakes are purchased for different situations, then adaptability is improved, but cost and device complexity increase
Solution Approach 1:
A single grading rake equipped with an adjustable rake guide system can replace multiple fixed rakes by accommodating different grading requirements through repositioning the rake guide along the guide track, reducing the total number of tools needed.
Solution Approach 2:
The invention combines multiple grading capabilities into one tool by integrating an adjustable rake guide mechanism that can be repositioned to perform various grading functions, merging what would traditionally require separate rakes into a single versatile device.
3Measurement precision
If user judgment is used for leveling accuracy, then no additional device is needed, but measurement precision and reliability are compromised
Solution Approach 1:
The adjustable rake guide system provides self-guidance for leveling by allowing the user to set and maintain a predetermined distance from the secondary surface, eliminating the need for continuous user judgment and measurement while maintaining accuracy.
Solution Approach 2:
The user can pre-set the desired distance from the secondary surface by adjusting the rake guide position before beginning the grading work, establishing accurate reference parameters in advance that guide the entire grading process without requiring continuous measurement.
4Adaptability or versatility
If a fixed rake guide position is used, then the device is simpler, but adaptability to different secondary surfaces is reduced
Solution Approach 1:
The rake guide is designed to be movable along the guide track with adjustment mechanisms that allow easy repositioning to different locations, enabling the user to adapt the rake guide position to match different secondary surface heights and configurations.

AI summary
An adjustable guided rake apparatus and method, which enable an adjustable guided rake user to configure an adjustable rake guide to a specified height in relation to a secondary surface, which will then define the height of the grading edge of the grading rake head in relation to a primary surface. The adjustable guided rake user is able to move the grading rake head along a primary surface, in order to shift material along the surface, while the adjustable rake guide runs along the secondary surface, guiding the grading rake head.
