Spray Bar Assembly with Segmented Reservoirs to Reduce Drying Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surface cleaning apparatuses with spray bar assemblies face inefficiencies in fluid distribution and retention, leading to uneven cleaning and increased drying times, particularly due to limitations in reservoir design and fluid flow paths.
Innovation Solution
The design incorporates a spray bar assembly with a cover featuring an elongate protrusion within the first reservoir to reduce volume capacity, a dividing wall separating reservoirs, and rib walls within the initial reservoir to disperse fluid evenly, along with a fluid flow path that directs fluid from the inlet through the initial and middle reservoirs to the outlets, optimizing fluid distribution and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the reservoir volume is increased to improve fluid distribution coverage, then the fluid distribution evenness is improved, but the drying time increases due to excessive fluid retention
Solution Approach 1:
The reservoir is divided into multiple separate reservoirs (first reservoir, second reservoir, third reservoir) arranged in series along the fluid flow path. Each reservoir has a smaller individual volume but collectively provides sufficient fluid distribution coverage. The segmentation allows fluid to be distributed evenly through multiple outlets while reducing the total fluid retention volume, thus shortening drying time.
Solution Approach 2:
Flow distributors are introduced as intermediary components within each reservoir to control and regulate fluid flow. These flow distributors ensure uniform fluid distribution to multiple outlets while managing the fluid retention volume in each reservoir section, resolving the contradiction between distribution evenness and drying time.
2Loss of time
If the reservoir volume is decreased to reduce drying time, then the drying time is reduced, but the fluid distribution coverage and evenness deteriorate
Solution Approach 1:
Instead of using a single large reservoir, the system employs multiple smaller reservoirs arranged in series. Each reservoir contributes to the overall fluid distribution coverage while maintaining a compact individual volume. This segmentation achieves both reduced total fluid retention (shorter drying time) and sufficient distribution coverage through the series arrangement.
Solution Approach 2:
The reservoirs are arranged in a series configuration along the fluid flow path, utilizing the longitudinal dimension of the spray bar assembly. This spatial arrangement allows multiple reservoirs to be packed efficiently, providing adequate fluid distribution coverage without increasing the overall volume excessively, thus maintaining short drying times.
3Speed
If the fluid flow path is simplified to improve processing speed, then the fluid delivery speed is improved, but the fluid distribution evenness deteriorates
Solution Approach 1:
The fluid flow path is segmented into multiple sections, each corresponding to a separate reservoir and outlet group. This segmentation allows fluid to flow through multiple parallel paths simultaneously, maintaining high overall delivery speed while ensuring even distribution through the distributed outlet arrangement across different reservoir sections.
Solution Approach 2:
The system uses multiple flow distributors within each reservoir to create redundant fluid distribution paths. This partial replication of distribution functionality ensures that even if one path varies, others compensate, maintaining even fluid distribution while the overall multi-reservoir configuration preserves fast fluid delivery speed.

AI summary
A cleaning apparatus includes a housing, a base operably coupled to the housing, a supply tank, and a spray bar assembly in fluid communication with the supply tank. The spray bar assembly includes a cover that defines a protrusion and a body coupled to the cover. The body includes a fluid inlet and a fluid outlet each in fluid communication with an interior. A first reservoir is defined within the interior. The first reservoir is disposed between the fluid inlet and the fluid outlet. The protrusion is disposed within the first reservoir to reduce a volume capacity of the first reservoir. A second reservoir is defined within the interior proximate to the first reservoir. A fluid flow path through the spray bar assembly is defined from the fluid inlet, through the first reservoir and the second reservoir, and through the fluid outlet.
