Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional backflow designs are used to enable spraying in inverted state, then spraying capability in inverted state is improved, but device complexity increases
Solution Approach 1:
The connecting pipe is divided into three distinct sections (upper, middle, lower) with different functional characteristics. Each section has specifically designed flow passages (back flow passages in upper section, forward flow passages in lower section) that work together to achieve bidirectional spraying capability while keeping each segment's structure relatively simple and manageable.
Solution Approach 2:
The check valve and check ball act as intermediary components that mediate between the upper and lower pipe sections. These intermediaries control the flow direction automatically based on the container's orientation, enabling the system to adapt to both upright and inverted states without requiring complex mechanical actuators or multiple valve mechanisms.
2Reliability
If complex component structures are used to achieve bidirectional flow control, then flow control reliability is improved, but manufacturing cost increases
Solution Approach 1:
The check valve and check ball form a self-regulating flow control system that automatically adjusts to the container's orientation without external control. When inverted, the check ball naturally blocks the lower pipe section while allowing flow through the middle section via the check valve. When upright, the check ball moves to allow flow through the lower section. This self-service mechanism eliminates the need for complex actuators, sensors, or control systems, thereby reducing manufacturing costs while maintaining reliable bidirectional flow control.
Solution Approach 2:
The invention uses simple, inexpensive components such as a basic check valve and check ball instead of complex, expensive mechanisms. These components are designed to be functionally sufficient rather than overly engineered, reducing material costs and assembly complexity while achieving the required reliability for bidirectional spraying.
3Adaptability or versatility
If multiple flow passages and valve components are assembled, then flow control functionality is improved, but assembly convenience deteriorates
Solution Approach 1:
Multiple functional components (upper pipe section with back flow passages, middle pipe section with check valve, lower pipe section with forward flow passages, and check ball) are merged into a single integrated connecting pipe assembly. This unified structure allows all components to be assembled together as one unit, simplifying the overall assembly process compared to having separate, distributed flow control mechanisms that would need to be installed and coordinated independently.

Function Achieved in This Case
The solution provides a cost-effective and easy-to-assemble flow guide device that ensures efficient liquid flow in both orientations, maintaining convenience and reducing manufacturing costs while preventing backflow.
Implementation Method 1
The check valve is assembled and arranged in the middle pipe section, so as to allow the liquid entering the middle pipe section from the back flow passages to unidirectionally pass therethrough to enter the flow guide pipe
Implementation Method 2
The check ball is assembled and arranged in the lower pipe section and at the port of the straw, so as for timely preventing the liquid from back flowing into the straw or flowing from the middle pipe section into the lower pipe section

AI summary
A flow guide device of a spray container which comprises a bottle, a nozzle having a flow guide pipe and a straw is configured to be connected between the flow guide pipe and a suction pipe. The flow guide device includes a connecting pipe, a check valve and a check ball. The connecting pipe is connected with the flow guide pipe, which has a plurality of back flow passages and forward flow passages formed on the inner edge thereof. The check valve is arranged between the connecting pipe and the flow guiding pipe. The check ball is arranged in the connecting pipe and located on the port of the straw. When the spray container is in an inverted state, the liquid enters the connecting pipe, the one-way valve and the flow guide pipe from the backflow channel, and the check valve, wherein the flow guide pipe through the back flow passages is finally sprayed out. Accordingly, the flow guiding device has a simple structure and is convenient to assemble and capable of reducing the overall manufacturing costs.
