Snowplough Curb Deflector Segmentation Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow plow clearing blades face issues with lateral wear and damage from collisions with obstacles, particularly curbs, due to inadequate protection, leading to reduced clearing width and potential safety hazards from loose components.
Innovation Solution
A curb deflector design that forms a fixed, yet separable connection with the clearing bar, utilizing two interlocking partial circle elements and a screw-nut arrangement to prevent loosening, combined with a robust material composition for enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a one-piece design of clearing bar and curb deflector is used, then the connection strength is improved, but the ease of repair deteriorates because the entire device must be replaced if one part is damaged
Solution Approach 1:
The curb deflector is divided into two separable parts: a first partial circle element and a second partial circle element. These can be independently replaced while maintaining a strong form-fit connection with the clearing bar, resolving the contradiction between connection strength and ease of repair.
Solution Approach 2:
The two partial circle elements are nested together to form a complete circular curb deflector that fits around the clearing bar. This nested structure provides strong protection while allowing individual elements to be replaced separately if damaged.
2Ease of operation
If external clamping screws are used to hold the rotating curb deflector, then the ease of operation is improved, but the reliability deteriorates because the screws can loosen and parts can fall onto the road
Solution Approach 1:
The two partial circle elements are combined to form a complete circular deflector that encloses the clearing bar, eliminating the need for external clamping screws. This merged structure prevents loosening while maintaining operational effectiveness.
Solution Approach 2:
The circular curb deflector is nested around the clearing bar, creating a enclosed structure that prevents detachment without requiring external fastening screws, thus improving reliability while maintaining ease of operation.
3Area of stationary object
If the curb deflector has a polygonal or rounded contour, then the area of protection is improved, but the device complexity increases
Solution Approach 1:
The curb deflector is designed with a circular cross-section formed by two partial circle elements. This curved geometry provides comprehensive protection against impacts from all directions while maintaining a simple two-part structure that is easy to manufacture and assemble.
