The Seeker would like to be able to measure the side bend offset of long crane arms in real or near real time. Solvers are asked to develop a device/method to make this measurement and provide data as proof.

This is a Reduction-to-Practice Challenge that requires written documentation and a device/method to be tested.


Long crane arms bend for many reasons such as wind, uneven heating, improper maintenance, etc. If the offset becomes too great it can be an extreme safety hazard. The Seeker would like a device/method to measure the side bend offset of long crane arms in real time. The crane arms are up to 120 meters long and a precision of 0.1 % of the length is required.

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 device/method to do the measurement and experimental proof of its ability.  

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.
