Snowplow Blade C-Shape Funnel Geometry for Snow Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snowplow blades lack optimal design for efficient snow removal, as they do not effectively utilize the shape and dimensions to facilitate a funnel action that enhances snow discharge.
Innovation Solution
A snowplow blade with a C-shaped cross-section and specific dimensions, including varying widths and heights, is designed to create a funnel action that directs snow upward and outward, allowing for faster and more efficient snow discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional snowplow blade design is used, then the structure is simple and easy to manufacture, but the snow discharge efficiency is insufficient due to lack of optimal funnel action
Solution Approach 1:
The snowplow blade employs a C-shaped cross-section with curved surfaces that form a funnel geometry. The blade features a bottom portion, sides, and a top portion that curves upward and outward, creating a smooth transitional surface that guides snow along a curved path from the center toward the ends, enhancing the funnel action and discharge efficiency
Solution Approach 2:
The blade design incorporates three-dimensional geometric features including varying widths (narrower at bottom, wider at top) and varying heights (taller at ends, shorter at mid-section), creating a complex 3D funnel shape that transforms snow flow from a simple planar movement to a multi-dimensional flow pattern that improves discharge performance
2Productivity
If a snowplow blade with varying width and height dimensions is designed to create funnel action, then snow discharge efficiency improves, but manufacturing precision requirements increase
Solution Approach 1:
The blade design specifies particular dimensional parameters including width ratios (top width significantly greater than bottom width) and height variations (end heights significantly greater than mid-section height), along with specific angle ranges (upward width angles and upward height angles between 5-35 degrees). These parameter specifications provide clear manufacturing targets while maintaining the essential funnel geometry function

AI summary
By controlling the dimensions of a snowplow blade, improved snowplow performance may be achieved. In one embodiment, the snow that is being plowed moves both upward and outward from the mid-section of the snowplow blade toward and beyond each end of the snowplow blade.
