The Seeker is looking for an algorithm that can calculate the length of a stressed cable in cantilever construction machinery and its relationship with the force needed to keep the equipment straight will be required.

This is a Reduction-to-Practice Challenge that requires a working computational model and software (which contains original program) to be tested with the Seeker's measured data.


In cantilever construction equipment, force is applied to a cable to keep the equipment arm straight. The problem is in knowing how long of a cable is required to do this and its relationship to the force applied. It is required to know both the unstressed cable length and its true length while under stress given the known data as described in the Challenge.

The submission to the Challenge should include the following:

  1. A detailed description of your proposed Solution addressing specific Solution Requirements presented in the Detailed Description of the Challenge. This description should be accompanied by a well-articulated rationale supported by literature/patent precedents.
  2. A computational model and software to test against real data.

Receipt of a Challenge award is contingent upon theoretical evaluation and experimental validation of the submitted Solutions by the Seeker.

To receive an award, the Solvers will have to transfer to the Seeker their exclusive Intellectual Property (IP) rights to the solution. However, the Seeker will be willing to consider a licensing agreement for a partial award if exclusive IP cannot be transferred by the Solver.

Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on October 22, 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. 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 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.
