Trigger Sprayer Adapter Layout for Upright and Inverted Spraying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger-type liquid sprayers require a large cap diameter to accommodate both a storage cylinder and an invertible adapter for continuous spraying in upright and inverted postures, leading to increased size and reduced operability.
Innovation Solution
A trigger-type liquid sprayer design with a longitudinal supply cylinder, storage cylinder, and invertible adapter that allows continuous spraying in both postures without significantly increasing cap diameter, using a switching valve to manage liquid flow based on posture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both storage cylinder and invertible adapter are provided, then continuous spraying in both upright and inverted postures is enabled, but cap diameter becomes large and overall size increases
Solution Approach 1:
The storage cylinder is positioned inside the mounting cap, and the invertible adapter is integrated within the same space. The storage plunger moves vertically within the storage cylinder, allowing all components to nest efficiently. This nested arrangement enables continuous spraying in both upright and inverted postures while keeping the cap diameter small and maintaining compact overall size.
2Volume of moving object
If storage cylinder extends in forward/rearward direction, then volume is secured while minimizing size, but spatial arrangement becomes complex
Solution Approach 1:
The storage cylinder extends in the forward/rearward direction (longitudinal dimension) rather than radially outward. This dimensional change allows the storage volume to be increased without increasing the cap diameter. The storage plunger moves vertically to displace liquid forward into the storage cylinder, efficiently utilizing the longitudinal space while maintaining a compact radial footprint.
3Adaptability or versatility
If invertible adapter is provided for spraying in both postures, then versatility is improved, but device complexity increases
Solution Approach 1:
The invertible adapter serves multiple functions: it enables liquid intake from the container body in both upright and inverted postures, and it directs liquid flow to the spray hole regardless of container orientation. By integrating this multi-functional adapter with the storage cylinder and plunger mechanism, the system achieves versatile posture-independent spraying without requiring separate systems for each 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
Enables continuous spraying in both upright and inverted postures while maintaining a compact size, improving operability and reducing interference with other components.
Implementation Method 1
a storage plunger configured to be movable rearward through the storage cylinder in a forward biased state according to supply of the liquid into the storage cylinder, and configured to cause the liquid in the storage cylinder to flow toward the spray hole
Implementation Method 2
an invertible adapter with a changeover valve that allows communication between different spaces based on the container's posture
Implementation Method 3
when the trigger part is pulled rearward, the liquid in a cylinder of the main pump part flows toward a spray hole by pressurizing the inside of the cylinder

AI summary
A trigger-type liquid sprayer including a sprayer body mounted on a container body, a nozzle member having a spray hole, and an invertible adapter. The sprayer body includes a longitudinal supply cylinder part, a trigger mechanism having a trigger part, a storage cylinder, and a storage plunger. The invertible adapter includes an adapter main body configured to form a first and second space, the first space configured to bring the container body in communication with an inside of the longitudinal supply cylinder part through an upright introduction port, and the second space configured to bring an inside of the container body in communication with the first space through an inverted introduction port, and a changeover valve configured to block communication between the first and second spaces when the container body is upright and bring the first and second spaces in communication with each other when the container body is inverted.
