Liquid Spraying Nozzle for Banknote Staining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medium storage boxes face difficulties in staining banknotes stacked at high relative positions due to the configuration of the liquid spraying mechanism, which often interferes with conveyance members, resulting in incomplete staining of all stored media.
Innovation Solution
The medium storage box incorporates a liquid spraying mechanism with a pipe section and two types of liquid spray holes: one that sprays ink sideways and another that sprays it upwards, allowing for comprehensive staining of banknotes across a wide area, including those at high positions without interfering with conveyance members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the pipe section of the liquid spraying nozzle is disposed at a high relative position to spray liquid on medium stacked at high positions, then the staining coverage is improved, but the pipe section interferes with the conveyance member
Solution Approach 1:
The invention changes the spray direction from purely horizontal to include an upward component by forming the liquid spray holes to spray liquid in a direction oblique to the horizontal direction. This dimensional change in spray trajectory allows the liquid to reach high-positioned medium without requiring the pipe section to be physically positioned at high locations, thereby avoiding interference with conveyance members while expanding staining coverage.
2Adaptability or versatility
If the pipe section is formed shorter and disposed lower down to avoid interfering with the conveyance member, then the device compatibility is improved, but medium at high relative positions cannot be stained
Solution Approach 1:
By changing the spray direction to oblique (upward component) while keeping the pipe section short and low-positioned, the invention enables liquid to reach high-positioned medium through trajectory extension rather than physical extension of the pipe. This resolves the contradiction between device compatibility and staining coverage.
Solution Approach 2:
The invention changes the spray parameter (direction angle) from horizontal to oblique, which fundamentally alters the liquid trajectory. This parameter change allows the same short, low-positioned pipe section to achieve staining coverage of high-positioned medium that would otherwise require a long, high-positioned pipe section.
3Device complexity
If liquid is sprayed sideways from the liquid spray holes, then the mechanism simplicity is improved, but medium at high relative positions remains unstained
Solution Approach 1:
The invention modifies the spray direction parameter from purely horizontal (sideways) to oblique (upward component included). This parameter change enables high-positioned medium to be stained while maintaining the simplicity of the spray mechanism, as no additional components or complex mechanisms are required—only a change in the spray hole orientation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration ensures that all stored banknotes are effectively stained, including those at high positions, using a limited amount of ink and preventing the medium from being used if stolen, thereby deterring criminal activity.
Implementation Method 1
stain the medium (banknotes) to which the liquid has been adhered
Implementation Method 2
sprayed liquid drips downward under its own weight

AI summary
A medium storage box includes a guide member and a liquid spraying mechanism. The guide member forms a stacking space for a medium. The liquid spraying mechanism sprays a liquid from a liquid spraying nozzle. The liquid spraying nozzle has a pipe section through which liquid flows, a first liquid spray hole and a second liquid spray hole. The first liquid spray hole sprays liquid in a direction that intersects an extension direction of the pipe section at substantially a right angle. The second liquid spray hole sprays liquid in a direction that is approximately the extension direction of the pipe section.
