Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing water spouting apparatus faces challenges in molding as a single piece from resin due to difficulties in removing the molding die from the collision portion and spout port conduit, leading to limited resin options and potential performance deterioration when divided into two members, which can result in shape accuracy issues and reduced functionality.
Innovation Solution
A water spouting apparatus design where the oscillation generating element is composed of two members, with a vortex street conduit connecting upstream and downstream members, allowing for easy mold extraction and maintaining high shape accuracy by ensuring no step difference in the flow path, thus preventing performance degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the oscillation generating element is molded as a single piece from resin, then the structure is integrated and compact, but the molding die cannot be removed from the space between the collision portion and the spout port conduit
Solution Approach 1:
The oscillation generating element is divided into two separate members: a first member containing the collision portion and a second member containing the spout port conduit. This segmentation allows the molding die to be removed from each member independently, solving the mold extraction problem while maintaining structural integration through precise fitting and alignment of the two members.
2Ease of manufacture
If the oscillation generating element is divided into two members, then mold extraction is facilitated and resin selection is expanded, but the shape accuracy of the vortex generating conduit decreases at the connecting portion
Solution Approach 1:
The oscillation generating element is divided into two members that can be molded separately with high precision, then assembled together. Each member can be manufactured with optimal mold designs, and the connecting portion is designed with complementary geometries that ensure precise alignment and eliminate step differences, maintaining shape accuracy while facilitating mold extraction.
Solution Approach 2:
The first and second members are designed to fit together precisely, merging into a unified structure that maintains the shape accuracy of a single-piece construction. The connecting portion between the two members is carefully engineered to eliminate discontinuities and step differences, ensuring that the combined structure achieves the same dimensional accuracy as an integral mold.
3Ease of manufacture
If the oscillation generating element is divided into two members, then ease of molding is improved, but step differences may form along the vortex generating conduit narrowing the flow path
Solution Approach 1:
The oscillation generating element is segmented into two members that can be molded separately with optimized die designs. The connecting portion between the members is specifically engineered with complementary geometries that ensure smooth transitions and eliminate step differences, maintaining continuous flow path characteristics while enabling easier molding processes.
Solution Approach 2:
Instead of trying to remove the mold from a single integrated piece (which is impossible), the design inverts the approach by dividing the piece into two separable members. The connecting portion is then designed with inverted geometry features that compensate for potential misalignments and prevent step differences, ensuring flow path continuity.

AI summary
The present invention is a water spouting apparatus (1) that discharges water with reciprocal motion, and has a water spouting apparatus body (10) and a oscillation generating element (22). The oscillation generating element includes a water supply conduit (24), a collision part (30) that generates a vortex on the downstream side, a vortex street conduit (26) provided downstream of the water supply conduit, and a discharge conduit that discharges water guided by the vortex street conduit. The vortex street conduit is configured by connecting the upstream member (18) on which the upstream side is formed and the downstream member (20) on which the downstream side is formed. At the connection between the upstream and downstream members, the height of the vortex street at the upstream end of the downstream member (H2) is higher than the height (H1) of the vortex street at the downstream end of the upstream member.
