Rodstock Barrel Drive Assembly for Precise Insertion Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rodstock insertion devices lack the ability to control the depth of insertion into composite materials, leading to inconsistent bonding between layers and increased risk of delamination due to varying thicknesses in different regions.
Innovation Solution
A rodstock barrel drive assembly featuring intermeshing roller gears with gripping surfaces and a motor-driven gear system allows precise control over rodstock insertion depth, enabling independent control of multiple rodstocks within a composite component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a needle drive assembly is used to create holes in composite material, then hole creation efficiency is improved, but control over rodstock insertion depth is lost
Solution Approach 1:
The drive assembly is segmented into multiple independent roller gear units, each capable of controlling rodstock insertion depth individually. This segmentation allows different regions of the composite component to receive rodstocks at different depths, solving the depth control problem while maintaining efficient array-based operation
Solution Approach 2:
The roller gears are designed with adjustable positioning capabilities, allowing the insertion depth to be dynamically controlled for each rodstock. The rollers can be positioned at different locations along the rodstock length, enabling precise depth control while maintaining the efficiency of batch processing
2Stability of the object's composition
If maximum depth of insertion is governed by minimum thickness region, then uniform insertion depth across all rodstocks is achieved, but bonding strength in thicker regions is reduced
Solution Approach 1:
Each roller gear unit can be independently positioned to provide local quality control over rodstock insertion depth. Thicker regions receive deeper rodstock insertion while thinner regions receive shallower insertion, optimizing bonding strength in each local area rather than using a uniform depth across the entire component
3Adaptability or versatility
If multiple rodstock barrel drives are required for complex components, then coverage of all regions is improved, but device complexity increases
Solution Approach 1:
Each roller gear unit is designed as a universal module that can handle different rodstock diameters and insertion depth requirements. This multi-functionality allows a single standardized unit type to be used across multiple positions, reducing overall system complexity while maintaining the ability to cover complex component geometries

AI summary
A rodstock barrel drive having a first and second roller gears, each having a toothed section and a gripping surface section, such that the teeth of the roller gears intermesh, causing rotation of one of roller gear to rotate the other roller gear in the opposite direction, so as to draw a rodstock through a space between the gripping surfaces of the pair of roller gears, a ring gear which engages with one of the pair of roller gears, a drive gear which engages with the ring gear, and one or more idler gears which engage with the ring gear, all within a housing, the drive gear being connected to, and rotated by, a motor, which causes the rodstock to be drawn through the roller gears, wherein all the gears are all positioned within, and oriented parallel to, a common plane.
