Dust-Mitigating Rake With Suction Head for Tile Removal Debris
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Floor tile removal generates significant debris and dust, posing health risks and violating environmental regulations due to the inefficiency of existing debris handling methods in capturing dust during the process.
Innovation Solution
A dust mitigating device comprising a rake with a collection head and suction ports, aligned with the rake's axis, coupled to a negative pressure source to draw dust into an exit passage, effectively reducing dust generation by utilizing a hinge for removability and materials like steel or plastic for durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If traditional debris handling methods are used during floor tile removal, then debris can be collected and removed, but significant dust is generated during the material handling process
Solution Approach 1:
The debris handling system is segmented into distinct functional components: a rake for initial debris gathering, a collection head for dust capture, and a negative pressure source for suction. This segmentation allows each component to perform its specific function optimally while working together to reduce overall dust generation during the debris removal process
Solution Approach 2:
A collection head with suction ports acts as an intermediary device between the rake and the negative pressure source. This intermediary captures dust at the point of generation during material handling and directs it into the suction system, preventing dust from escaping into the environment while maintaining efficient debris removal
2Object-generated harmful factors
If a collection head with suction ports is added to the rake, then dust capture capability is improved, but the device complexity increases
Solution Approach 1:
The collection head is merged with the rake to form an integrated dust mitigating device. The suction ports are positioned along the second axis of the collection head, which is substantially parallel with and proximate to the first axis of the rake, creating a unified structure that combines debris gathering and dust capture functions without requiring separate equipment
Solution Approach 2:
The collection head serves multiple functions: it acts as a structural support for the suction ports, provides a pathway for dust to enter the suction system through the exit passage, and maintains proper alignment with the rake during operation. This multi-functionality reduces the need for additional components and simplifies the overall device structure
