Valve handwheels are common on every Naval ship, ranging from two inch polymer supply line valves to metal hand wheels several feet in diameter. The range and ubiquity of these handwheels poses a challenge as it is untenable for individual ships to maintain a stock of every single variation onboard. Modern techniques such as additive manufacturing can produce needed parts on demand but challenges remain in both certification and design. This Challenge seeks a parametric design tool in the form of an executable file that will automatically generate the necessary CAD files to allow on-demand manufacturing of specific handwheels on board a Naval ship.
Handwheels are ubiquitous on Naval ships and any particular ship may have hundreds of different variations. They’re used to open and close a wide variety of valves in all types of service locations and conditions, and can be made from a number of different materials from polymers to metals. These factors lead to a challenge for ships since it is untenable to keep a stock of every single variant onboard and this may result in delays as critical equipment lays dormant for want of a particular part. The viability of using additive manufacturing and other advanced techniques to produce a variety parts on demand has been demonstrated but challenges remain for both certification and design. The Seeker is in need of an executable file that will take guided user input for the type of handwheel required, design parameters such as diameter, thickness, etc., manufacturing technique, and other critical parameters and automatically produce the CAD files necessary to allow on-demand production of the handwheel using the specified technique.
A submission to the Challenge should include the following:
- A detailed description of the proposed Solution addressing specific Technical Requirements presented in the Detailed Description of the Challenge. This should also include a thorough description of the executable file used in the Solution accompanied by a well-articulated rationale for the method employed.
- Output from the proposed executable file for a test case as described in the Detailed Description of the Challenge.
- Well-documented source code, object files and an executable with sufficient documentation to enable the Seeker to compile, execute the program, and validate the method using additional test cases.
- User guide for operation of the program.
The Challenge award is contingent upon evaluation of the executable file by the Seeker, and validation by the Seeker of the submitted reduction to practice Solution on additional test cases.
To receive an award, the Solvers will not have to transfer their exclusive IP rights to the Seeker. Instead, Solvers will grant to the Seeker a non-exclusive license to practice their solutions. Please see the Challenge Specific Agreement (CSA) for full details.
Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on 13-Jul-2021.
Late submissions will not be considered.
