TRIZ trends predict an increased electrification of engineering systems. One of the visible effects of this is lighting, in this case party lights on boats. The need to furnish a boat with colorful illumination requires a flexible, redispatchable system. Cable-bound illumination does not meet this requirement. A solution is presented in this paper using TRIZ as a problem-solving methodology. TRIZ comprises a set of heuristic tools for problem analysis, reformulation, root cause analysis, and problem-solving algorithms. TRIZ, however, concentrates on generating solutions to problems irrespective of given limitations concerning, for example, safety, producibility, or cost. TRIZ provides a direction of thinking that has been proven successful in the past for similar problems. Other tools must, nevertheless, be used to carry out a technical evaluation of the feasibility of the solution, scalability, practicability, or cost target. TRIZ tools are widely used by engineers in multinational corporations such as Intel, GE, Philips, Siemens, Bosch, Boeing, Samsung, LG, and Cochlear. In this paper, selected tools from the overall TRIZ toolbox will be used and explained, with a focus on functional analysis, trimming, and resources. However, other aspects (Trends, Function Oriented Search (FOS), and Ideal Final Result (IFR)) will also be presented.
