Orientable Cup for Aerosol Nozzle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for orienting the tip of a paint aerosol nozzle in a trolley are prone to delays and inaccuracies due to the difficulty in correctly positioning the nozzle perpendicular to the carriage's direction of travel.
Innovation Solution
An orientation cup with a housing featuring frustoconical surfaces and flats that facilitate the insertion and rotation of the nozzle tip, allowing for easy alignment and secure positioning within the cup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the aerosol tip is manually positioned for correct orientation, then the nozzle can be inserted into the carriage, but the operation causes delays and positioning inaccuracies
Solution Approach 1:
The frustoconical surfaces and flats on the cup's inner wall automatically orient the aerosol tip during insertion. The geometry of these surfaces guides the tip into the correct perpendicular position relative to the carriage direction without requiring manual adjustment, making the system self-orienting and eliminating time-consuming manual positioning operations
Solution Approach 2:
The cup is pre-configured with specific frustoconical surfaces and flats designed to automatically orient the aerosol tip during the insertion process itself. This preliminary geometric arrangement ensures that the correct orientation is achieved as part of the insertion action, rather than requiring a separate positioning step after insertion
2Manufacturing precision
If the aerosol tip is manually positioned for correct orientation, then the nozzle can be inserted into the carriage, but positioning inaccuracies occur
Solution Approach 1:
The frustoconical surfaces and flats on the cup's inner wall automatically orient the aerosol tip during insertion. The geometry of these surfaces guides the tip into the correct perpendicular position relative to the carriage direction without requiring manual adjustment, making the system self-orienting and eliminating time-consuming manual positioning operations
Solution Approach 2:
The cup features asymmetric geometric elements including frustoconical surfaces with specific angles and flats positioned at predetermined locations. This asymmetric geometry creates a unique fit that only allows the aerosol tip to be oriented correctly, preventing incorrect orientations and ensuring precise perpendicular alignment with the carriage direction
3Ease of operation
If frustoconical surfaces are used in the cup housing, then the opening dimensions are increased for easier insertion, but the structure becomes more complex
Solution Approach 1:
The cup employs frustoconical surfaces with smooth curved geometry instead of flat or angular surfaces. These curved surfaces naturally guide the aerosol tip during insertion, providing self-aligning properties that facilitate easy insertion while maintaining a relatively simple single-piece molded structure
