Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water outlet devices with swinging water splash functions are complex, have low reliability, and high manufacturing costs due to the need for multiple gears driven by high-speed impellers to maintain appropriate swing frequencies.
Innovation Solution
A simplified swing structure featuring a swing member within a water passing chamber, where the swing member's design allows it to swing due to water flow impact, eliminating the need for complex gear systems by utilizing the water flow's torque to achieve a reciprocating swing, thereby reducing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If an impeller with multiple gears is used to drive the water outlet member, then the swing frequency can be maintained within an appropriate range, but the structure becomes more complicated and reliability decreases
Solution Approach 1:
The patent extracts and removes the complex gear transmission system from the traditional impeller-driven structure. Instead of using an impeller with multiple gears to maintain swing frequency, the invention directly uses water flow impact on the swing member to achieve the desired reciprocating motion, eliminating unnecessary mechanical components and simplifying the overall structure.
Solution Approach 2:
The swing member utilizes the kinetic energy of water flow directly to drive its own reciprocating motion without requiring external gear mechanisms. The water flow itself serves as both the power source and the actuator, allowing the swing member to self-generate the required swing frequency through its interaction with the water stream.
2Speed
If an impeller with multiple gears is used to drive the water outlet member, then the swing frequency can be maintained within an appropriate range, but the manufacturing cost increases
Solution Approach 1:
The patent removes the expensive gear transmission components and impeller mechanism, replacing them with a simple swing member that can be manufactured as a single piece or with minimal components. This extraction of complex mechanical elements directly reduces manufacturing costs while maintaining the essential swing frequency function through direct water flow actuation.
3Ease of operation
If an impeller with multiple gears is used, then the water outlet member can swing, but the overall reliability is low
Solution Approach 1:
The patent extracts and eliminates the gear train and impeller components that are prone to failure, wear, and mechanical breakdown. By removing these intermediate transmission elements, the system achieves direct water flow-to-motion coupling, which significantly improves reliability by reducing the number of moving parts that can fail.
Solution Approach 2:
The swing member directly converts water flow kinetic energy into reciprocating motion without relying on mechanical transmission components. This self-actuating mechanism eliminates gear wear, bearing failures, and connection point breakdowns, thereby enhancing overall system reliability while maintaining the water outlet swing function.

AI summary
The present disclosure discloses a swing structure and a corresponding water outlet device. A water passing chamber in a body of the swing structure is equipped with a swing member, and an upper end of the swing member is provided with a recess facing a water inlet hole of the water passing chamber. The water flow impacts the recess to drive the swing member to swing to one side randomly. After a lower end of the swing member is out of range of a water outlet hole of the water passing chamber, the upper and lower ends of the swing member are adjacent to or abut against a wall of the water passing chamber, so that the swing member can swing back and forth.
