Ceiling Texture Scraping Assembly with Integrated Collection Pan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scraping devices are ineffective in efficiently removing popcorn texture from ceilings, particularly textured sheetrock, as they lack a suitable mechanism to engage and collect the texture effectively.
Innovation Solution
A scraping device comprising a pan with fasteners coupling lateral walls to an outer wall, a grippable sleeve, and a blade that frictionally engages the ceiling texture, allowing the pan to be positioned beneath the ceiling and collect the texture as it is scraped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing scraping devices are used to remove popcorn texture from ceilings, then the scraping action can be performed, but the texture cannot be effectively collected and disposed of
Solution Approach 1:
The patent combines the scraping blade function with the collection pan into a single integrated device. The blade is positioned within the pan structure, allowing scraped texture to fall directly into the pan during the scraping motion, eliminating the need for separate collection and disposal steps.
Solution Approach 2:
The pan serves as an intermediary container that receives and holds the scraped texture material. This intermediate collection mechanism allows the operator to accumulate texture in the pan before disposal, significantly improving ease of operation compared to traditional scraping methods where material falls to the floor.
2Productivity
If a pan structure is added to collect scraped texture, then collection efficiency improves, but device complexity increases
Solution Approach 1:
The device is segmented into distinct functional components: the pan body for collection, the blade for scraping, the handle for operation, and the fasteners for assembly. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity through modular construction.
Solution Approach 2:
The pan structure serves multiple functions simultaneously: it acts as the collection container for scraped texture, provides structural support for mounting the blade, and offers a grip surface for the handle. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
3Productivity
If the blade is designed to frictionally engage the ceiling texture, then removal effectiveness improves, but the blade may damage the sheetrock underneath
Solution Approach 1:
The blade is designed with specific local properties: a relatively narrow width compared to the pan opening, a specific angle of attack, and a blade material and thickness selected to cut texture fibers without excessive force. These localized quality adjustments allow effective texture removal while minimizing the risk of damaging the underlying sheetrock surface.

AI summary
A ceiling texture scraping assembly includes a pan that may be manipulated having the pan being positioned beneath a ceiling. A plurality of fasteners is provided. Each of the fasteners extends through an associated one of the tabs and engaging an associated one of the lateral walls. Thus, each of the lateral walls is coupled to the outer wall. A sleeve is coupled to and extends away from the pan and the sleeve may be gripped. A blade is coupled to the pan. The blade frictionally engages texture on the ceiling. Thus, the blade to removes the texture from the ceiling.
