Trade fairs, conferences and congresses serve to exchange expertise and knowledge. Often the existing potential cannot be used despite high concentration of knowledge carriers or is subject to barriers in the communication. This paper presents a proven design of an open workshop, which offers the possibility to involve the participants of such events for an interdisciplinary exchange, up to the targeted scientific, social or economic problem solving. The design of the workshop will involve participants being led by a “step-by-step guide (“Workshop Tourguide”). By setting the framework and the specific request for individual ideas, the first step is to create an “Idea Market” that will be made visible to everyone. In a development loop, the ideas are verified and developed within the knowledge ecosystem in order to continue their work in groups. Through the process of making all ideas visible and accessible at all times, ideas are effectively enhanced in their quality. In the final step, the ideas in teams are worked out with the help of the “Proposal Design Canvas” and recorded for further development. As it has been shown, by applying this design, empirical barriers to knowledge exchange and communication can be resolved in order to work cooperatively on solution proposals. The workshop design can be applied to dynamic and fluctuating events such as trade fairs, conferences and congresses in order to interrogate bundled knowledge, bring it together in a targeted manner and further develop it through grinding processes. The “Workshop Tourguide” serves as an adaptable template that can be used for all creative solution finding.
