Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scraping devices are limited in functionality and require multiple tools to handle different tasks related to removing sealant and glue from windows and doors, such as cutting, scraping, and applying new sealant, making them inefficient for various situations.
Innovation Solution
A multi-functional scraping device with interchangeable scraping members, a pivotable design, and integrated tools like a cutter and stop plates, allowing for efficient removal and application of sealant in various scenarios, including corners and narrow areas, with a silicon or rubber spreading plate for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional scraping devices are used, then the device structure is simple, but the functionality is limited and multiple tools are needed
Solution Approach 1:
The patent combines multiple scraping members with different functions (straight scraping member for general scraping, V-shaped scraping member for corners, spreading plate for sealant application) into a single handle assembly, allowing users to perform multiple sealant-related tasks with one tool instead of carrying multiple separate tools
Solution Approach 2:
The handle assembly is designed as a universal platform that can accommodate various scraping members and accessories through attachment mechanisms, enabling a single device to perform cutting, scraping, smoothing, and spreading operations that previously required multiple specialized tools
2Adaptability or versatility
If multiple tools are carried to handle different situations, then various tasks can be performed, but the carrying burden increases
Solution Approach 1:
By merging multiple scraping members and accessories into one integrated handle assembly, the patent reduces the number of separate tools users must carry, directly decreasing the total weight and carrying burden while maintaining the ability to handle various sealant removal and application tasks
3Productivity
If a single tool is designed to handle multiple tasks, then the need for multiple tools is reduced, but the device complexity increases
Solution Approach 1:
The device is segmented into modular components including the handle, multiple interchangeable scraping members, and attachment mechanisms. This segmentation allows for functional integration while maintaining structural organization, enabling efficient multi-tasking without excessive complexity

AI summary
A scraping device includes a first grip with a first scraping member connected thereto. A connection member is connected to the first scraping member. A second grip is pivotably connected to the first grip and has a second scraping member connected thereto. A spreading plate has multiple rounded corners, and a fixing hole is defined in the spreading plate. The connection member is connected to the fixing hole to connect the spreading plate to the first scraping member. A third scraping member is connected to the pivotal position between the first and second grips. The scraping device has multiple functions.
