Wire Brush Handle and Detachable Scraper for Better Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire brushes lack improved performance and ergonomic design, particularly in handle functionality and user grip options, which limits their effectiveness and usability.
Innovation Solution
A wire brush design featuring a handle with a finger separator extending at least 6.35 mm downwardly, multiple finger receiving areas for comfortable grip, and a manually adjustable mechanical fastener for attaching or detaching a scraper body, enhancing ergonomic handling and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional handle design is used, then the structure is simple, but the user grip options and comfort are limited
Solution Approach 1:
The handle is segmented into multiple functional zones including a first finger receiving area, a second finger receiving area, and a finger separator, allowing different grip options while maintaining a unified handle structure
Solution Approach 2:
The handle design provides multiple grip configurations (first grip option with four fingers in the first area, second grip option with one finger in the second area) within a single handle structure, making it adaptable to different user preferences and tasks
2Adaptability or versatility
If a fixed scraper attachment is used, then the structure is simple, but the versatility and adaptability are reduced
Solution Approach 1:
The scraper body attachment mechanism transitions from a fixed design to a dynamically adjustable design, allowing the scraper to be attached or detached based on operational needs, thereby increasing versatility
Solution Approach 2:
The scraper assembly is separated into a scraper body and the brush, connected through a mechanical fastener system with tabs and grooves, allowing independent attachment and detachment of the scraper component
