Dual Press Spray Head With Elastic Coupling For Versatile Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray heads are not user-friendly as they are either press-type or gun-type, lacking versatility to adapt to user preferences, environments, and purposes.
Innovation Solution
A dual press spray head that combines a press-type portion for directional pressure and a gun-type portion for user-pull operation, allowing selective use based on user preferences and needs, featuring a head portion with a discharge portion, gun-type and press-type components, and a coupling mechanism with elastic nozzle parts for efficient content discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spray head is designed as either press-type or gun-type, then the operation is simplified for a specific user preference, but the adaptability to different user preferences and environments is reduced
Solution Approach 1:
The spray head is designed to incorporate both press-type and gun-type operating mechanisms within a single device. The press-type portion includes a pressing mechanism that activates when pressure is applied, while the gun-type portion includes a pulling mechanism that activates when pulled. This multi-functional design allows the same spray head to serve different operational needs and user preferences, resolving the contradiction between operation simplicity and adaptability.
2Device complexity
If a single operating mechanism is used, then the device complexity is reduced, but the versatility to adapt to different spraying needs is limited
Solution Approach 1:
The spray head is divided into distinct functional segments: a press-type portion with a pressing mechanism, a gun-type portion with a pulling mechanism, and a common discharge portion. Each segment can operate independently to activate the discharge portion, allowing the device to provide multiple spraying modes without requiring a completely separate device for each function. This segmentation maintains relative structural simplicity while achieving versatility.
3Productivity
If elastic nozzle parts are used for coupling, then the content discharge efficiency is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The coupling mechanism utilizes elastic nozzle parts that can deform under pressure to create a secure connection. The elasticity of the material allows the nozzle parts to flex during coupling and discharging, maintaining a reliable seal without requiring extremely tight manufacturing tolerances. This parameter change from rigid to elastic coupling enables efficient content discharge while reducing the stringency of manufacturing precision requirements.

AI summary
Disclosed is a dual press spray head including: a head portion coupled to a top of a can having an internal space in which contents are accommodated; a discharge portion communicating with an inside of the head portion and discharging the contents to an outside; a gun-type portion mounted to the head portion and coupled to the discharge portion to operate the discharge portion; and a press-type portion mounted to the head portion and pressing the head portion in a downward direction of the can, wherein one side of the press-type portion comes into contact with the gun-type portion so that the head portion and the gun-type portion are pressurized simultaneously in the downward direction of the can to operate the discharge portion.
