The Seeker wishes to build a model that will predict the scale of fluid loss resulting from damage to a highly branched network of conduits. Several obvious variables such as vessel diameter are known to influence the scale of fluid loss. The Seeker wishes to incorporate less obvious factors in a model that has a high predictive accuracy. More contextual details are included in the detailed challenge description. 

This is an Ideation Challenge with a guaranteed award for at least one submitted solution.


A small scale, highly branched network of tubes distributes fluid under pressure around a complex structure. The tubes vary in diameter and fluid pressure & flow rates vary across the network. Individual tubes within the network may be damaged during necessary interventions to the structure. Fluid loss resulting from damage to tubes can irreversibly damage the structure. The Seeker wishes to construct a model that will predict the scale of fluid loss based on physico-chemical parameters of the tubes and the fluid contained within. 

This is an Ideation Challenge, which has the following unique features:

  • There is a guaranteed award.  The awards will be paid to the best submission(s) as solely determined by the Seeker. The total payout will be $10,000, with at least one award being no smaller than $5,000 and no award being smaller than $1,000. 
  • The Solvers are not required to transfer exclusive intellectual property rights to the Seeker.  Rather, by submitting a proposal, the Solvers grants to the Seeker a royalty-free, perpetual, and non-exclusive license to use any information included in this proposal.

After the Challenge deadline, the Seeker will complete the review process and make a decision with regards to the Winning Solution(s).All Solvers that submitted a proposal will be notified on the status of their submissions; however, no detailed evaluation of individual submissions will be provided.

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. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.

What is an InnoCentive Ideation™ Challenge?

An InnoCentive Ideation™ Challenge is a broad question formulated to obtain access to new ideas, similar to a global brainstorm for producing a breakthrough idea or market survey which may include ideas for a new product line, a new commercial application for a current product, or even a viral marketing idea to recruit new customers. Ideation™ Challenge submissions are typically about two written pages, and Seekers receive a non-exclusive, perpetual license to use all submissions.

In an Ideation™ Challenge, Solvers may:

  • Submit ideas of their own
  • Submit third party information that they have the right to use and further the authority to convey that right and the right to use and develop derivative works to Seekers
  • Submit information considered in the public domain without any limitations on use

Solvers should not reveal any confidential information in their submissions. Often the Ideation™ Challenge will be followed by one or more of the other three Challenge types to further develop the ideas and gain Intellectual Property protection when the concept has been well-defined.
