Problem
Existing snow rakes are large and difficult to store, display, and ship due to their fixed elongated pole and straight blade design, which limits their disassembly and adjustability.
Innovation Solution
A snow rake with adjustable V-shaped blade assembly and a disassemblable design, featuring hinged rake members and a modular extension pole, allowing for easy assembly, use, and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the snow rake uses a fixed elongated pole and straight blade design, then the structural simplicity is maintained, but the device becomes large and difficult to store, display, and ship
Solution Approach 1:
The pole is divided into multiple telescopic sections that can be nested within each other, reducing the overall length and volume when stored. The blade assembly is separated into adjustable components that can be folded or reconfigured to minimize space occupation.
Solution Approach 2:
The pole incorporates telescopic mechanisms allowing dynamic adjustment of length, and the blade assembly includes adjustable angles and configurations. This dynamic design enables the device to transition between a compact stored state and an extended operational state, resolving the contradiction between structural simplicity and storage volume.
2Ease of manufacture
If the snow rake uses a fixed straight blade design, then the manufacturing simplicity is maintained, but the adaptability to different snow conditions and roof types is limited
Solution Approach 1:
The blade assembly is designed with adjustable components that allow users to modify the blade angle and configuration based on different snow conditions and roof types. This dynamic adjustability enhances versatility while maintaining relatively simple manufacturing processes through modular design.
Solution Approach 2:
The adjustable blade assembly can be configured for multiple functions and conditions, making a single device adaptable to various snow removal scenarios. This multi-functionality is achieved through adjustable mechanisms that allow the same basic structure to serve different purposes without requiring multiple specialized blades.
3Length of moving object
If the snow rake uses an elongated fixed pole design, then the operational reach is maximized, but the device cannot be easily disassembled for compact storage
Solution Approach 1:
The pole is segmented into multiple telescopic sections that can be easily extended for maximum reach during operation and collapsed into a nested configuration for compact storage. The segmentation allows the pole to transition between long and short states while maintaining ease of assembly and disassembly through simple locking mechanisms.
Solution Approach 2:
The telescopic pole incorporates dynamic length adjustment capabilities, allowing users to extend the pole to its full length for operational reach and then collapse it for storage. This dynamic design resolves the contradiction by making the pole both long when needed and compact when stored, with easy transition between states.

AI summary
A snow rake for moving snow from a roof. The snow rake includes an elongated extension pole comprising a plurality of pole sections which may be connected together in an end-to-end manner. First and second rake members are secured to the upper end of the extension pole. The first and second rake members are hingedly connected together so as to be able to be positioned in a straight position or a V-shaped position. Pivot support arms extend from the rake members to a clamp which is longitudinally adjustably secured to the extension pole. The clamp may be adjustably moved on the extension pole to change the positions of the rake members. The components of the snow rake may be placed in a box for display, shipment or storage.
