Segmented Floor Scraper Shield for Hydraulic Hose Debris Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial floor scraper equipment shields do not adequately protect electrical and hydraulic hoses from flying debris, particularly in commercial hydraulic floor scrapers, leading to potential damage and costly repairs.
Innovation Solution
An L-shaped debris deflecting shield is mounted on the front and lateral portions of a floor scraping vehicle, comprising a front shield, wedge shield, and side shield, made of sturdy materials like steel or aluminum, to protect hydraulic and electrical components from debris while allowing the scraper's operation without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no shield is installed, then the device complexity is low and ease of manufacture is high, but the reliability of hydraulic and electrical hoses deteriorates due to exposure to flying debris
Solution Approach 1:
The shield is divided into multiple segments: a front shield portion, a side shield portion, and a rear shield portion. Each segment can be independently mounted and protects specific areas. This segmentation allows the shield to provide comprehensive protection while maintaining ease of installation and replacement, resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The shield extends in multiple dimensions - front-to-back length, side-to-side width, and vertical height - to create a three-dimensional protective barrier around the hydraulic hoses and electrical components. This multi-dimensional approach ensures complete coverage of exposed areas while maintaining a simple planar construction that does not significantly increase device complexity.
2Reliability
If a comprehensive shield is installed to protect all exposed areas, then the reliability improves, but the ease of operation deteriorates due to potential interference with scraper operation
Solution Approach 1:
The shield is designed with flexible mounting that allows it to move with the suspension system during scraper operation. The shield can dynamically adjust its position as the scraper blade moves up and down, ensuring continuous protection of hydraulic hoses while never interfering with the scraping operation itself.
Solution Approach 2:
The shield provides protection only in the specific areas where hydraulic hoses and electrical components are exposed to debris, rather than enclosing the entire scraper. The front shield portion protects the front exposed areas, the side shield portion protects lateral exposed areas, and the rear shield portion protects rear exposed areas, allowing full operational access where protection is not needed.
3Strength
If heavy-duty materials are used for the shield, then the strength and protection capability improve, but the weight of the shield increases
Solution Approach 1:
The shield utilizes composite construction combining steel components for structural strength with aluminum components for lighter weight areas. This composite approach provides adequate debris resistance through strategic placement of heavier materials only where impact resistance is critical, while reducing overall shield weight in areas requiring less structural strength.
Solution Approach 2:
The shield is designed as a relatively simple, potentially replaceable component rather than a permanent integrated structure. By using simpler materials and construction methods, the shield can be easily replaced if damaged, reducing the need for overly robust (and heavy) materials that would be required for a permanently integrated protective structure.

AI summary
An industrial floor scraper equipment shield having an industrial floor scraper assembly, a front shield assembly, a fastening assembly, a wedge shield assembly, and a side shield assembly is disclosed herein. The industrial floor scraper assembly includes a ride on floor scraping vehicle that has hydraulic hoses that are used to power and operate the scraper blade. The shields of the aforementioned assemblies are mounted to the front and sides of the industrial floor scraper, said shields are attached to said industrial floor scraper using said fastening assembly. Thereby covering the previously exposed hydraulic hoses and create a debris deflecting shield. Wherein the shield helps prevent the hydraulic hoses from being damaged by any flying sharp debris.
