Crevice Cleaning Nozzle Guide for Precise Crack Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crevice cleaning tools lack guidance, making it difficult to maintain the optimal position over cracks and crevices during cleaning, leading to inefficient debris removal before applying sealants or grout in construction and tiling projects.
Innovation Solution
A guide means is integrated into crevice cleaning tools, either as a fixed or rotatable attachment, featuring a head and elongated portion to assist in maintaining the tool's position over the crack or crevice, with options for attachment to existing tools or as a modified design with a fixed guide mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple crevice cleaning tool is used, then the device complexity is low, but the positioning precision over cracks and crevices deteriorates
Solution Approach 1:
The patent introduces a guide attachment as an intermediary component that couples between the operator and the crevice cleaning tool. This guide attachment provides visual alignment markers and physical guidance edges that help position the tool accurately over cracks and crevices without requiring complex integrated positioning systems in the main tool body.
2Measurement precision
If a guide means is added to the crevice cleaning tool, then the positioning precision improves, but the device complexity increases
Solution Approach 1:
The patent divides the crevice cleaning system into two separate components: the basic crevice cleaning tool and the guide attachment. This segmentation allows the guide functionality to be added only when needed, maintaining the simplicity of the core cleaning tool while providing enhanced positioning capability through an optional attachment that can be easily attached or removed.
3Measurement precision
If the guide means is held in a fixed position, then the positioning precision is improved, but the ease of operation deteriorates due to reduced flexibility
Solution Approach 1:
The guide attachment is designed with flexible positioning capabilities, allowing it to be adjusted to different angles and orientations depending on the specific crack or crevice geometry. The guide can be rotated or repositioned along the crack path, providing dynamic adaptability that maintains both positioning precision and operational flexibility across various cleaning scenarios.

AI summary
A crack and crevice cleaning tool has a portion of circular cross section for attachment to a source of vacuum such as a vacuum cleaner, and a flattened nozzle portion for placement next to a crack or crevice and guide means mounted at the end of the nozzle portion and insertable in the crack or crevice being cleaned to guide the tool.
