Inflatable Body Structure for Liquid Jet Ejection Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing children's toys that dispense liquids, such as water pistols, often lack safety features to prevent injury upon contact, as they do not deform to reduce the risk of harm and may not return to a predictable aiming position after contact.
Innovation Solution
A liquid jet ejection device featuring a flexible lumen and an inflatable body structure made from polyvinyl chloride (PVC) that deforms upon contact with an object, deflecting the nozzle to reduce injury risk and returning to its original pose for predictable aiming, combined with a pump system for liquid ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a rigid body structure is used to maintain stable aiming position, then aiming precision is improved, but injury risk upon contact increases
Solution Approach 1:
The body structure is made from an inflatable material that can deform upon contact with a user or object. This flexible shell allows the nozzle to deflect and the structure to compress, reducing injury risk while maintaining a stable base form for predictable aiming when not in contact.
Solution Approach 2:
The body structure transitions between a stable base form for aiming and a deformed state upon contact. The dynamic response allows the structure to adapt to contact conditions, compressing to reduce harm while returning to the base form to maintain aiming precision.
2Object-affected harmful factors
If a deformable body structure is used to reduce injury risk, then safety is improved, but aiming precision deteriorates
Solution Approach 1:
The body structure maintains a stable base form during normal operation for precise aiming, and only deforms upon contact with a user or object. This dynamic behavior ensures that deformability is activated only when needed for safety, not during normal aiming.
Solution Approach 2:
The inflatable body structure is pre-configured in a base form that provides stable aiming characteristics. This preliminary configuration ensures predictable aiming behavior before any contact occurs, with the deformability reserved as a safety response.
3Object-affected harmful factors
If the body structure deforms upon contact, then safety is improved, but device complexity increases
Solution Approach 1:
The body structure is constructed as a single inflatable shell made from a flexible material that inherently provides both the stable base form and the deformability upon contact. This unified structure avoids the need for complex mechanisms, sensors, or active control systems.
Solution Approach 2:
The inflatable body structure automatically deforms in response to contact forces without requiring external control systems, sensors, or power sources. The material properties and structural design enable the safety response to occur passively, reducing overall device complexity.
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
The device effectively reduces the risk of injury by deforming upon contact and returning to a safe, predictable aiming position, ensuring safe and controlled liquid dispensing.
Implementation Method 1
the body structure being deformable from the base form via contact with an object, the body structure returning to the base form upon withdrawal of contact with the object
Implementation Method 2
a pump coupled to the flexible lumen, the pump being actuatable to eject a liquid from the liquid source via the output end

AI summary
A liquid jet ejection device is provided. The liquid jet ejection device has a flexible lumen having an intake end positioned to be in fluid communication with a liquid source, and an output end distal from the intake end. A pump is coupled to the flexible lumen, the pump being actuatable to eject a liquid from the liquid source via the output end. A body structure extends from a handle and supports the output end of the flexible lumen, the body structure having a base form in which the output end of the flexible lumen is supported in a base pose relative to the handle, the body structure being deformable from the base form via contact with an object, the body structure returning to the base form upon withdrawal of contact.
