The Seeker desires a new method to rapidly and precisely join bundles of brass-coated high carbon (> 0.70%) steel filaments end-to-end.

This is a Reduction-to-Practice Challenge that requires a written proposal and experimental proof-of-concept data (and/or sample delivery).


The Seeker is searching for a method to join bundles of high carbon (0.70 – 0.90% carbon) steel filaments that is rapid, robust, and produces strong joints consistently with no need for rework.  The steel filaments are coated with brass and have diameters from 0.1 to 0.4 mm and are twisted into bundles from 0.4 to 5.0 mm in diameter.

A submission to the Challenge should include the following:

  1. A detailed description of the 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. Experimental proof-of-concept data, if available, may also be submitted in support of the proposed Solution.
  2. Submissions will be evaluated on a rolling basis, and based on the detailed description and supporting rationale, the Seeker will determine Solutions that merit experimental validation and those Solvers will be sent samples of steel cord on which to demonstrate their method and return them for testing by the Seeker. Video of the process performed on the samples is also requested at this stage.
  3. Submissions must be received by the posted deadline in order to be eligible for the experimental validation stage of the Challenge.

The 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. 


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.
