Shower Head Dispersion Pins Eliminate Spacers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing showerheads require spacers to maintain gap uniformity and fix intermediate plates, which increases fabrication complexity and obstructs rapid and reliable gas dispersion in the lateral direction.
Innovation Solution
The showerhead design incorporates dispersion pins that protrude from the body to support the ceiling and intermediate plates, eliminating the need for additional spacers and allowing gas to flow through passages and inlet holes for uniform dispersion without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If spacers are added to maintain gap uniformity and fix intermediate plates, then structural stability is improved, but device complexity and fabrication difficulty increase
Solution Approach 1:
The dispersion pin structure is merged with the support function by making the pins protrude from the intermediate plate to directly support the ceiling, eliminating the need for separate spacers. This integration resolves the contradiction by achieving structural stability through the combined support-dispersion function of the pins rather than through additional spacer components.
Solution Approach 2:
The dispersion pins serve multiple functions: they disperse gas laterally while simultaneously supporting the ceiling and maintaining gap uniformity. This multi-functionality resolves the contradiction by eliminating the need for dedicated spacers, thereby reducing fabrication complexity while maintaining structural stability.
2Stability of the object's composition
If spacers are added to fix intermediate plates, then structural support is improved, but gas dispersion speed and reliability deteriorate due to obstruction
Solution Approach 1:
The support function is merged into the dispersion pin structure itself, which protrudes to support the ceiling while maintaining the intermediate plate position. This eliminates separate spacers that would obstruct gas flow, resolving the contradiction by achieving fixation without obstruction.
Solution Approach 2:
The harmful spacers are extracted from the system by replacing them with dispersion pins that perform both support and dispersion functions. This removal of obstructive elements resolves the contradiction by enabling rapid gas dispersion while maintaining intermediate plate fixation through the pin structure.
3Manufacturing precision
If multiple intermediate plates and gas supply parts are added to improve gas distribution, then gas dispersion uniformity is improved, but device complexity increases
Solution Approach 1:
The dispersion function is segmented into multiple dispersion pins distributed across the intermediate plate, each with its own gas inlet hole and passage. This segmentation enables uniform gas distribution through multiple discrete flow paths while avoiding the complexity of multiple intermediate plates and gas supply parts.
Solution Approach 2:
Each dispersion pin is equipped with local gas inlet holes and passages tailored to its position, enabling localized gas dispersion control. This local quality approach achieves overall uniform gas distribution without requiring complex multi-plate structures, resolving the contradiction by distributing simplicity across multiple simple components.

AI summary
A showerhead is provided. The showerhead includes a body and a plurality of first dispersion pins. The body has one side having a plurality of injection holes penetrated therethrough and the other side facing the one side. The plurality of first dispersion pins protruding from the plurality of spray holes of the one side to the other side such that end portions thereof support the other side. The first dispersion holes have first gas inlet holes on one side and first passages connected to the first gas inlet holes therein. Gas introduced between the one side and the other side is immediately discharged to the outside of the body through the plurality of spray holes by passing the first gas inlet holes and the first passages.
