Flat Plastic Strip Bristles for Snow Brush Anti-Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car snow brushes with yarn or flexible sheet bristles face issues such as dirt accumulation, bristle tangling, and scratching due to snow or dirt accumulation between bristles, leading to reduced effectiveness and appearance.
Innovation Solution
A car snow brush featuring elongated and flat plastic strips as bristles, arranged in multiple rows with overlapping configurations and a scraper, designed to prevent snow accumulation and provide flexibility and surface adaptation, manufactured using Thermoplastic Elastomer material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If yarn or flexible sheet bristles are used, then the brush can remove snow, but material accumulates between the bristles making it difficult to remove and potentially scratching the car
Solution Approach 1:
The patent uses flat plastic strips as bristles instead of traditional yarn or flexible sheets. These strips are formed from a flexible plastic material that can bend and adapt to the car surface while maintaining a smooth, continuous structure that prevents dirt accumulation. The strips are arranged in overlapping rows to ensure complete coverage without gaps where dirt could accumulate.
Solution Approach 2:
The invention employs a composite structure combining flexible plastic material with a rigid handle. The plastic strips are made from a material that provides both flexibility for surface adaptation and sufficient stiffness for effective snow removal. The composite design integrates the strips with the handle through molded connections, creating a unified structure that maintains strip alignment and prevents tangling.
2Adaptability or versatility
If thin bristles are used, then the brush can reach tight spaces, but the bristles get bent and tangled after use decreasing appearance and performance
Solution Approach 1:
The flat plastic strips are designed with sufficient width and thickness to maintain structural integrity while remaining flexible. The strips can bend to conform to curved car surfaces but resist tangling due to their flat, streamlined shape and the way they are arranged in overlapping rows. The material properties are specifically selected to provide memory recovery, allowing strips to return to their original position after bending.
3Productivity
If multiple rows of strips are used, then snow removal efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple rows of flat plastic strips into a single molded component that attaches to the handle. The strips are arranged in overlapping rows during the molding process, creating a unified structure that provides multiple rows of cleaning action without requiring separate components. This merging approach maintains snow removal efficiency while simplifying the overall device structure and reducing the number of assembly steps.
