Linear Shaped Charge Holder for Epoxy Curing Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Linear shaped charges require manual sanding and frequent monitoring during epoxy curing due to their prone nature of falling over, leading to time-consuming processes and inefficiencies.
Innovation Solution
A holder with a support structure that stabilizes the linear shaped charge during epoxy curing, eliminating the need for sanding and constant alignment checks, featuring a rectangular midsection, stair-step risers, and curved legs for secure placement in a container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual sanding is performed on linear shaped charges, then the ends become flat and ready for potting, but the process becomes time-consuming due to the number of samples
Solution Approach 1:
The holder is designed with a pre-formed rectangular cavity that automatically provides the flat end surface needed for potting. By inserting the LSC into the holder, the flat end is already prepared without requiring manual sanding, thus eliminating the time-consuming sanding step while maintaining the required flatness for proper potting.
2Reliability
If linear shaped charges are placed upright in epoxy pot, then they can be cured, but they are prone to falling over and require frequent monitoring and position correction
Solution Approach 1:
The holder provides localized support at specific critical points along the LSC. The rectangular cavity with its specific dimensions and the positioning features create a localized support structure that prevents the LSC from falling over, while the rest of the LSC remains free to cure properly in the epoxy pot.
Solution Approach 2:
The holder acts as an intermediary device between the LSC and the epoxy pot. It provides the necessary support and stability during curing, preventing the LSC from falling over, while allowing the epoxy to cure uniformly around the LSC without requiring frequent monitoring and position correction.
3Ease of manufacture
If the support structure is made with a raised midsection, then it prevents bonding to epoxy during curing, but adds structural complexity
Solution Approach 1:
The support structure is segmented into distinct functional zones: a raised midsection portion and a lower support portion. The raised midsection acts as a barrier to prevent epoxy bonding, while the lower support portion provides the necessary structural support. This segmentation allows each portion to perform its specific function effectively while maintaining overall structural integrity and reusability.

AI summary
Disclosed is a holder for stabilizing a linear shaped charge during epoxy curing. The device includes a support with a rectangular midsection having a first and a second end, and a central aperture; a pair of stair-step risers extending down from the first and the second end; and a pair of curved legs extending from the stair-step risers. The pair of curved legs lock the support onto a container. A linear shaped charge is positioned within the central aperture and extends downward into the container where it is stabilized while a curing agent within the container hardens. The support removes the need for constantly checking the alignment of the liner shaped charge while curing and prevents the need for sanding, both of which save considerable time when compared to previous methods. The support is designed with a raised midsection to prevent it from being bonded to the epoxy during the curing process, thereby allowing it to be reused.
