Honeycomb Panel Nozzle Tip for Uniform Resin Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nozzles for dispensing setting resins into honeycomb cores lack effective designs for uniform resin application, leading to inconsistent reinforcement in honeycomb panels, particularly in segments that require specific reinforcement for hardware or cut-through features.
Innovation Solution
A nozzle design featuring a connector portion for resin delivery and an application head with a flange surrounding an exit hole, where the flange has a planar surface with a minimum width greater than 0.5 cm and curves upward, allowing for controlled and uniform application of setting resins into honeycomb core cells, enhancing reinforcement in specific panel segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing nozzles are used for dispensing setting resins, then the dispensing process can be completed, but the resin application is non-uniform leading to inconsistent reinforcement
Solution Approach 1:
The nozzle design incorporates a flange with a specific planar surface geometry (minimum width greater than 0.5 cm) that creates a controlled dispensing zone. This local structural feature ensures uniform resin distribution across the honeycomb core surface, directly addressing the uniformity and consistency issues in reinforcement application.
2Manufacturing precision
If a simple nozzle design is used, then the device complexity is low, but the reinforcement in specific segments is inconsistent
Solution Approach 1:
The nozzle is divided into distinct functional segments: a connector portion for resin delivery and an application head with a flange for controlled dispensing. This segmentation allows each part to perform its specific function optimally, achieving consistent reinforcement while maintaining a relatively simple overall structure that can be integrally formed.
3Strength
If existing nozzles are used, then the dispensing can be performed, but the structural integrity of segments bearing hardware is insufficient
Solution Approach 1:
The flange design with its specific planar surface geometry (minimum width greater than 0.5 cm) creates a controlled dispensing pattern that ensures uniform resin distribution in critical areas. This local structural feature directly enhances the structural integrity of segments that will bear hardware or require cut-through features by ensuring consistent reinforcement quality.

AI summary
Nozzles are presented, for application of a setting resin into cells of a honeycomb core to provide the panel with reinforced segments. The nozzle comprises a connector portion and an application head, where the connector portion is adapted to receive setting resin from a resin dispensing device and deliver the setting resin to the application head, and the application head comprises: an exit hole, and a flange surrounding the exit hole. The flange comprises a bottom surface which comprises a planar surface which planar surface has a minimum width around the exit hole. The bottom surface of flange curves upward at its outer perimeter. In some embodiments, the nozzle is optically translucent or transparent. In addition, methods of applying a setting resin into cells of a honeycomb core to form a honeycomb core reinforcement are presented. In some embodiments, the setting resin is a low density void filler.
