Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spraying devices are not effective in efficiently cleaning the interior of containers, particularly the upper areas around the container opening, due to limitations in spray pattern distribution and reach.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If spray jets are emitted radially outward from fluid flow openings, then the spray pattern covers a wide area, but the spray jets may strike adjacent baffle plates before reaching the intended target, reducing cleaning effectiveness
Solution Approach 1:
The spray nozzle body is segmented into multiple radial zones, each with its own fluid flow opening and dedicated baffle plate. This segmentation ensures that each spray jet is confined to its own sector and strikes only its assigned baffle plate, preventing cross-interference while maintaining wide overall coverage through the distributed arrangement of multiple segments around the circumference
Solution Approach 2:
Each baffle plate is specifically positioned and shaped to match the characteristics of its assigned fluid flow opening. The local geometry of each baffle plate (including its curvature and orientation) is optimized for the specific spray jet it receives, ensuring precise deflection of that particular jet while avoiding interference with adjacent jets. This local optimization is achieved through dedicated alignment features that ensure each spray jet strikes only its intended baffle plate
2Adaptability or versatility
If baffle plates are arranged radially around the spray nozzle body, then spray jets can be deflected to cover upper container areas, but the baffle plates may interfere with each other if not precisely positioned
Solution Approach 1:
The baffle plates are designed with asymmetric geometries relative to the radial direction, with each plate having a specific curvature and orientation that is optimized for its position in the circumferential sequence. This asymmetric design allows each baffle plate to deflect its assigned spray jet in a unique pattern suitable for covering different areas of the container interior, while the asymmetric positioning prevents interference with adjacent plates by creating staggered deflection paths
Solution Approach 2:
The solution adds circumferential positioning as a critical dimension alongside the radial arrangement. By precisely controlling the circumferential angles and radial distances of each baffle plate, the system creates a three-dimensional spatial configuration where spray jets are deflected along distinct trajectories. This multi-dimensional positioning ensures that deflected jets from different baffle plates do not intersect, achieving spray pattern flexibility without excessive complexity
3Device complexity
If the spray nozzle remains stationary in the container, then the device structure is simplified, but the ability to reach all areas of the container interior is limited
Solution Approach 1:
The spray nozzle utilizes periodic alternation between multiple spray patterns by selectively activating different subsets of fluid flow openings and their corresponding baffle plates. By cycling through different combinations of active spray jets in a periodic manner, the stationary device achieves comprehensive coverage of the container interior over time, with each spray jet contributing to different areas during different phases of the cycle
Solution Approach 2:
The system compensates for the lack of physical movement by utilizing the circumferential dimension more fully. Multiple fluid flow openings are distributed around the entire circumference of the spray nozzle body, with baffle plates positioned at various circumferential angles and radial distances. This circumferential distribution creates multiple spray directions and deflection angles, allowing a stationary nozzle to cover the entire container interior by spraying in all radial directions simultaneously or in sequences
