RainTunes was one of the digital highlights at the world’s leading trade fair focusing on the responsible management of water and energy in buildings, the ISH 2019 in Frankfurt/Main. It shows the trend of digitization for modern bathroom design and intelligent home systems. RainTunes is a digital shower system and connects water, light, sound and scent. No other product on this fair was as sharply focused on forward looking smart home experience in this conservative branch. RainTunes is not just a digital product from a traditional brand like Hansgrohe, it was developed in a show case process with agile innovation management based on IP design.

RainTunes is designed to create a holistic showering experience. It is focusing on the individual needs of human beings and its mood. Hansgrohe developed the product with experts from different fields to create digital showering scenarios which are balanced and aligned with individual everyday life. Right now, seven multi-sensory showering scenarios are available. They are aligned with individual daily routines, atmospheres and moods. These scenarios where developed with dermatologists, sport medicine specialists, physiotherapists and specialists for aromatherapy. Customers can choose between experiences like “good morning”, “recreation”, “vitality”, “relaxation”, “beauty”, “nature” and “good night”.

The app developed for this purpose connects to the shower products of Hansgrohe via the local WLAN network. Even systems docked via WLAN, which are already used in smart homes, can be used to control light and sound. With a tap of the app, the selected shower scenario is transferred to the shower and started there via a play button. RainTunes is controlled either via buttons or via a pad. The control buttons can be freely placed in the bathroom. They can be used to regulate the spray types, water quantity and temperature. Thanks to Bluetooth technology, a completely new operation of the shower could be realized: the separation of permanently installed fittings and the control. Because the control buttons are connected to a central unit behind the wall via Bluetooth and therefore independent of an armature. Of course, there is also the possibility to control the daily shower ritual on the pad individually. Temperature, amount of water musical background and spray characteristic can be changed at any time.

RainTunes was developed with agile innovation management. Agile project management such as design thinking and IP design is fundamentally different from traditional project management. In agile project management, there is a different   emphasis on what a project should achieve and how. Not all project evaluation criteria of the traditional paradigm are given equal weight. Agile projects are characterized by a comparatively high tolerance when it comes to typical target variables such as scope, process, time and costs, and by significant client involvement. Agile project methods place a strong focus on deliverables and quality from the user’s perspective.

The RainTunes project focuses on redefining showering and what it means to customers: the move away from body care and personal hygiene to mental fitness, meditation, ritual retreats and short breaks from the stresses of everyday life. IP design leads to a permanent review cycle of the portfolio of options and scenarios for action and thus enables the company to evolve in the direction of different digital business models. Revision, adaptation and modification are therefore no longer a problem or a special case but reflect the actual purpose of IP design. IP design even takes into account scenarios which are undesirable from the company’s perspective and should be suppressed by IP. Even digital “night-mares” leading to disruption can be captured by patents without requiring those patents to be implemented.

The RainTunes project also allows Hansgrohe to derive key success factors for design thinking and IP design. The pivotal role of the project partners in the progress of IP design requires highly effective communication. The project-based working methods of IP design are in line with today’s interconnected work environment characterized by flat hierarchies, transparent contributions and solution-oriented thinking. This applies in particular to the agile overall approach involving design thinking methods.

Therefore, a corporate culture is needed that recognizes the creative contributions of the team members and prioritizes the outcome over planning. The methodology itself must also be secondary to the outcome, and to the exclusive character of the business model and the customer experience.
