The Seeker desires software to model the flow force and pressure distribution inside a hydraulic valve under various operating conditions. Solutions must be generally applicable to multiple valve designs. 

This is a Reduction-to-Practice Challenge that requires written documentation, software, and simulation output from the software applied to a supplied test case.



The Seeker designs and produces hydraulic valves for use in its products. The design process is currently trial-and-error in that for each new valve design a prototype must be produced in order to test the pressure and flow characteristics of the design. If the prototype does not have the desirable flow and pressure characteristics it must be re-designed and re-tested until its characteristics are within the required range. The cost and time involved in designing a new valve could be significantly shortened if the Seeker had a way to accurately model and predict the valve characteristics before producing a prototype and thus is seeking software to accomplish this task. The Solution should not require complicated and expensive commercial software packages that would be overkill for this specific application. 

A submission to the Challenge should include the following: 

  1. 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 method used in the Solution accompanied by a well-articulated rationale for this method.
  2. Executable software that simulates the hydraulic pressure field and flow force in a valve.
  3. Output from the software as applied to an example valve design provided in the Challenge. 

The Challenge award is contingent upon evaluation of the method by the Seeker, comparison of submitted output with test data, and validation by the Seeker of the submitted reduction to practice Solution. 

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. 

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on December 12, 2017.

Late submissions will not be considered.


What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million.

What is an RTP Challenge?

An InnoCentive RTP (Reduction to Practice) Challenge is a prototype that proves an idea, and is similar to an InnoCentive Theoretical Challenge in its high level of detail. However, an RTP requires the Solver to submit a validated solution, either in the form of original data or a physical sample. Also the Seeker is allowed to test the proposed solution. For details about treatment of IP rights, please see the Challenge-Specific Agreement.
