Landscape Rake With Foldable Heads And Adjustable Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pond rakes are not adjustable for users of different body types, lack a folding function, and are too wide for small ponds, making them impractical for use and storage.
Innovation Solution
A landscape rake with a length-adjustable handle and foldable/unfoldable rake heads, featuring a plurality of rods with hinge assemblies and linkage rod assemblies that allow for independent pivoting and configuration of the rake heads, enabling adjustment and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rake has a fixed handle length and fixed rake head configuration, then the structure is simple and easy to manufacture, but it cannot accommodate users of different body types and is not suitable for ponds of different sizes
Solution Approach 1:
The handle is divided into multiple rod segments that can be assembled in different combinations to achieve varying lengths. The rake heads are segmented and can be independently folded or extended, allowing the device to adapt to different user heights and pond sizes while maintaining manageable structural complexity through modular design
Solution Approach 2:
The rake incorporates dynamic elements including telescopic handle sections with hinge assemblies that allow length adjustment, and foldable rake heads that can change configuration between extended and compact states. This enables the device to transform from a fixed-configuration tool to an adaptable instrument suitable for various users and applications
2Ease of operation
If the rake head is fixed and non-foldable, then the structure is stable and simple, but the rake is too wide for small ponds and occupies excessive storage space
Solution Approach 1:
The rake heads are designed with hinge assemblies and linkage rod assemblies that enable them to fold toward the handle, transforming the rake from a wide, extended configuration to a compact, folded state. This dynamic capability allows the rake to pass through narrow spaces in small ponds and reduces storage volume significantly
Solution Approach 2:
When folded, the rake heads nest closer to the handle body, with the tines and plates arranged in a compact configuration that minimizes the overall volume. The linkage rod assemblies allow the rake heads to be positioned close to the handle, creating a nested arrangement that reduces both operational width and storage requirements

AI summary
A landscape rake of the present invention includes a rake handle component, a rake body component and at least two linkage rod assemblies. The rake handle component is assembled by a plurality of rods, and one of the rods has a first fixed portion and a second fixed portion. The rake body component has rake heads formed with a plurality of tines and pivotally assembled with the first fixed portion and the at least two linkage rod assemblies, respectively. Each of the at least two linkage rods has one end pivotally assembled with the second fixed portion. Accordingly, the rake heads can be unfolded or folded relative to the rake body component, thereby saving storage space and improving portability.
