Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the space for liquid storage is increased to enable continuous spraying, then the spraying time is extended, but the volume of the whole bottle increases and becomes inconvenient to carry
Solution Approach 1:
The pressure continuation chamber is nested within the existing pump body structure, utilizing the transverse passage and integrating the pressure continuation sealing seat into the pump's internal geometry. This allows the continuous spraying function to be achieved without adding external housing or increasing the overall bottle volume.
Solution Approach 2:
The invention utilizes the transverse passage dimension within the pump body to create the pressure continuation chamber, effectively using the horizontal space rather than increasing vertical height or external volume. This dimensional reorganization enables continuous spraying capability while maintaining a compact form factor.
2Reliability
If a housing is arranged outside the pump body to enable continuous spraying, then the spraying function is improved, but the assembly becomes troublesome and manufacture is complicated
Solution Approach 1:
The pressure continuation chamber, sealing seat, and spring mechanism are merged into a single integrated assembly that fits within the existing pump body. The pressure continuation sealing seat is positioned within the transverse passage and works in conjunction with the existing pump components, eliminating the need for separate external housing and reducing assembly steps.
3Reliability
If the spray head is designed with additional components for continuous spraying, then the spraying capability is improved, but the compatibility with different bottle types is limited
Solution Approach 1:
The spray head is designed with a standardized cover that connects to the bottle, while the continuous spraying mechanism (pressure continuation chamber and sealing seat) is integrated within the pump body. This modular design allows the same spray head to be compatible with different bottle types while maintaining the continuous spraying function.
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 design enables continuous spraying, is easy to assemble, cost-effective, and compatible with various bottles, maintaining a compact form factor.
Implementation Method 1
a pressure continuation spring supported between the pressure continuation spring seat and the pressure continuation sealing seat, driving the pressure continuation sealing seat to move upward so as to continuously extrude liquid in the pressure continuation chamber out to the transverse passage
Implementation Method 2
a spring supported between the inner surface of the main piston and the cylinder so as to move the main piston forward
Implementation Method 3
a spray outlet one-way valve on the pump body

AI summary
The spray head capable of spraying continuously comprises a main body having a liquid passage; a head cap; a spray one-way valve; an operating handle; and a pump. The liquid passage comprises a transverse passage and a vertical passage which communicate with each other. A pressure continuation sealing seat capable of moving up and down is disposed inside a sleeve, a pressure continuation chamber is defined on a top of the pressure continuation sealing seat. The pressure continuation spring is supported between the pressure continuation spring seat and the pressure continuation sealing seat, driving the pressure continuation sealing seat to move upward so as to continuously extrude liquid in the pressure continuation chamber out to the transverse passage. The present invention is simple and reasonable in structure, convenient to assemble, low in cost without additional housing disposed outside the main body, and good in universality.
