Concepts for novel or improved structures and materials that deliver improved absorbency are required. The structure/materialis intended for use in domestic environments to quickly absorb aqueous spills. The concept should be applicable for use with non-woven cellulose-based materials. More information is available within the detailed Challenge description. 

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


Conventional cellulose-based paper or non-woven matrices absorb liquids into pores between cellulose fibers, and pores within the fibers, through capillary action. The Seeker wishes concepts and designs that will increase the absorbent capacity of these matrices. A wide range of techniques have been used previously to increase both absorbency and retention of liquids. The Seeker is looking for novel structures and materials, or possibly treatments that modify the structure of the cellulose fibers, so that absorbency is increased. 

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.

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.
