Closed Spray Testing Container for Wax Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for verifying spray patterns from nozzles used for applying wax to vehicles are inefficient due to difficulty in detecting changes in spray patterns and cleaning up wax, which can lead to inaccurate measurements and unintended coverage.
Innovation Solution
A closed spray testing container with transparent side and end walls, a tinted bottom wall featuring a longitudinal and lateral scale, and a spray pattern representation, allowing for precise measurement and verification of spray patterns by inserting the nozzle and spraying wax onto the bottom wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spray pattern verification is performed visually on open surfaces, then the process is simple, but detection precision of spray pattern changes is poor
Solution Approach 1:
The patent replaces visual inspection with a structured measurement system using scales and reference patterns printed on the bottom surface. The transparent wall allows optical observation while the measurement markings provide quantitative verification, substituting subjective visual assessment with objective measurement references.
Solution Approach 2:
The transparent wall acts as an intermediary that allows light transmission for visual observation while the measurement markings on the bottom surface serve as an intermediary reference system. This intermediary measurement system enables precise spray pattern verification without requiring direct contact or complex equipment.
2Ease of manufacture
If wax is sprayed on open surfaces for testing, then application is straightforward, but cleanup difficulty increases
Solution Approach 1:
The patent extracts the measurement function from the spray surface itself by placing scales and reference patterns on the bottom wall. This allows the spray testing to be contained within the chamber, with wax collected on the bottom surface rather than being dispersed across multiple surfaces, significantly reducing cleanup time and effort.
3Ease of operation
If spray testing is performed in open environments, then accessibility is good, but wax migration to unintended surfaces occurs
Solution Approach 1:
The transparent wall acts as a containment boundary that prevents wax migration to unintended surfaces while allowing visual observation. The enclosed chamber structure confines the spray pattern to a controlled space, eliminating the harmful effect of wax spreading to surrounding areas.
4Measurement precision
If measurement scales are added to the container, then measurement precision improves, but device complexity increases
Solution Approach 1:
The patent merges the measurement function directly into the container structure by printing scales and reference patterns on the bottom wall. This integration eliminates the need for separate measurement devices or complex external measurement systems, achieving high measurement precision while maintaining simple container structure.

AI summary
A method of verifying measurements of a spray pattern from a nozzle is provided. The method includes inserting the nozzle through an opening in a bottom wall of a closed spray testing container. The closed spray testing container includes a pair of side walls and a pair of end walls connected to the side walls. A top wall is opposite the bottom wall and is connected to the pair of side walls and the pair of end walls to provide a volume. The top wall is transparent. The bottom wall includes at least one of a scale and a spray pattern representation provided on a surface of the bottom wall. At least one of the scale and the spray pattern is used to verify a spray pattern provided using the nozzle.
