Shower Head Jet Disc Holding Device With Plug Connector Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shower heads with a multiplicity of fine jet discharge openings face stability issues due to high internal pressures from fluid, such as limescale deposition, which traditional centric screw fastening methods cannot adequately address, especially when the jet disc has low dimensional stability and a high number of small passage cross-section openings.
Innovation Solution
A jet disc holding device utilizing plug connector pins and pin through-passage openings with radially elastically resilient edges and mushroom-shaped latching heads, allowing for secure attachment without screws, distributing holding force uniformly across the jet disc and resisting high fluid pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single centric screw is used for jet disc fastening, then the device complexity is reduced and assembly is simplified, but the holding force and stability under high internal pressure are insufficient
Solution Approach 1:
The single centric screw fastening is segmented into multiple peripheral fastening points. The jet disc holding device comprises multiple plug connector pins (at least two, preferably three or more) distributed around the periphery of the jet disc, each providing independent fastening. This segmentation distributes the holding force across multiple points, preventing discoloration and deformation under high internal pressure while maintaining relatively simple device complexity.
2Strength
If multiple fastening screws are used, then the holding force and stability are improved, but the device complexity increases and assembly becomes more difficult
Solution Approach 1:
The traditional screw fastening system is replaced with a plug connector pin system. The plug connector pins are inserted through peripheral openings in the jet disc and secured by latching heads that engage with corresponding latching edges in the base body. This substitution eliminates the need for threaded holes, nuts, and complex tightening operations, reducing device complexity while maintaining sufficient holding force through the distributed peripheral fastening arrangement.
3Productivity
If the jet disc has a high number of jet discharge openings, then the shower jet performance is improved, but the inherent stability and flexural stiffness of the jet disc decrease
Solution Approach 1:
The jet disc stability is segmented and reinforced by distributing multiple fastening points around the periphery. The multiple plug connector pins create multiple rigid connection points between the jet disc and base body, effectively segmenting the disc into stabilized zones. This peripheral fastening arrangement maintains the high number of jet discharge openings needed for shower jet performance while preventing discoloration and deformation through distributed mechanical support.
4Strength
If screws are used for fastening, then the holding force is sufficient, but the manufacturing cost increases and precision requirements are higher
Solution Approach 1:
The expensive screw fastening system is replaced with simpler plug connector pins. The pins are inserted through peripheral openings and secured by latching heads that engage with latching edges, eliminating the need for threaded holes, nuts, and precision tightening operations. This substitution reduces manufacturing cost while maintaining sufficient holding force through the distributed peripheral fastening arrangement, and lowers precision requirements for the fastening features.
