Modular Rake Tine Spacing and Wave Shape for Faster Sifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mucking rakes are either heavy and burdensome due to metal construction, prone to breaking if made of plastic, and lack versatility with fixed tine spacing and shape, requiring replacement of the entire tool if a single tine is damaged, and require inefficient manual sifting.
Innovation Solution
A modular mucking rake design featuring a handle with interchangeable, variable-spaced, and wave-shaped tines, allowing for customizable spacing and shape, with modular connectors and end caps for improved debris collection and reduced shaking effort, enabling multiple tool functions in one device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal construction is used for strength, then the rake becomes strong and durable, but it becomes heavy and burdensome
Solution Approach 1:
The rake is divided into modular components: a lightweight frame structure with interchangeable tines that can be separately replaced. This segmentation allows the use of lighter materials for the frame while maintaining overall strength through the modular design, eliminating the need for heavy unibody construction.
Solution Approach 2:
The rake combines different materials strategically: lightweight materials for the frame structure and stronger materials for the working tines. This composite approach optimizes the strength-to-weight ratio by applying material strength only where mechanically necessary.
2Weight of moving object
If plastic tines are used to reduce weight, then the rake becomes lightweight, but the tines break more often
Solution Approach 1:
The tine assembly is segmented into interchangeable modular units that can be independently replaced. This allows the use of lighter plastic materials for the tines while maintaining reliability through the ability to quickly replace broken tines without replacing the entire rake, effectively managing durability through maintenance rather than material selection alone.
3Device complexity
If fixed tine spacing is used for simplicity, then the rake structure is simple, but it lacks versatility for different materials
Solution Approach 1:
The rake employs adjustable and reconfigurable tine spacing mechanisms, allowing users to dynamically change the configuration of the tines based on the specific material being handled. This dynamic adaptability enables the same rake structure to efficiently process different aggregates from fine sawdust to larger wood chips.
Solution Approach 2:
The modular rake design with interchangeable tines and adjustable spacing creates a universal tool that can perform multiple functions across different farming and ranching applications, replacing the need for multiple specialized rakes with different fixed configurations.
4Device complexity
If straight tines are used for simplicity, then the rake structure is simple, but manual sifting time increases
Solution Approach 1:
The rake incorporates curved or wave-shaped tines instead of straight ones. This curvature creates a more effective sifting action that naturally guides material through the tines and collects it at the bottom, reducing the manual shaking and sifting time required while maintaining structural simplicity.

AI summary
The present invention relates primarily to an improvement in a mucking rake that can also be adapted for landscaping use. The invention possesses parallel replaceable tines that are spaced apart at variable distances through the use of individual modular tines and/or spacers. The tines can also be manufactured in a wavy shape to enable the debris to be sifted and collected onto the rake without having to dispose of the debris each time debris is sifted and collected.
