of consumers. The tenets of open design have inspired the development of public manufacturing facilities networks like Fab Lab, and laid the foundations of open design clearinghouses like Ponoko, Shareable and Instructables. In summary, the distinctions between the three archetypes of Open-X are more a matter of thrust and areas of application. They are not mutually exclusive. All three inherit the core features of openness and naturally overlap to some degree. Open design, for example, is not merely a matter of re-use and distributed manufacturing – it also entails sharing design blueprints and sharing extensions thereof, thus distributing knowledge and development. Building on the working definition of open design and an understanding of its unique features, the remainder of this article will discuss its potential, in particular addressing the infrastructure characteristics that are most conducive to its generative capability in the context of innovation.

       Unpacking Open Design

      Open design signifies open-access digital blueprints that can be adapted at will to meet situated requirements, and can subsequently be used by consumers to fabricate products on demand by commercial, off-the-shelf production methods. The open design model diminishes the traditional vertical value chain that is formed by designer-manufacturer-distributor-consumer relationships and offers an alternative, open web of direct links between designers and consumers. The resulting short-spanned, transient and non-hierarchical relationships forge dynamic and flexible arrays of blueprints that are not only user-centred but also user-driven.

      The discourse on open design encompasses a multitude of considerations: for example, design specification, fabrication, collaborative action, supply and value chain management, business models, legal aspects, technological infrastructure and normative values. The complexity of this ecology can be untangled to some extent by classifying the underlying issues of open design into four interdependent conceptual layers, as follows:

      Object layer refers to the design blueprints that enable and constrain the specification of the design artefacts. This layer encompasses the design and distribution of open design objects, that is, configurable and extensible blueprints that are available under open access license in online public repositories.

      Process layer refers to the means of production that enables and constrains the fabrication of the design objects. This layer encompasses open design fabrication, that is, the application and operation of commercial, off-the-shelf machinery like printers, PRINTING laser cutters or CNC machine tools to produce customized products with no custom-built moulds or machines.

      Practice layer refers to the work practices that enable and constrain the conception of the design processes. This layer encompasses open design culture, that is, the related nomenclature, professional standards, craftsmanship, rules of the trade, code of conduct, rituals and normative values.

      Infrastructure layer refers to the underlying institutional and technical foundations that enable and constrain the vitality of the design practices. This layer encompasses open design substructure, that is, the related legal system, market structure and technical architecture that govern open design activities and future growth.

      

      LAYERS OF OPEN DESIGN

      The discourse so far is focused on the object and process layers, with some touches upon the practice layer. However, quite surprisingly, despite its fundamental role, the infrastructure layer is virtually ignored.

       Designing Generative Infrastructure

      The infrastructure that governs open design activities, business models and development is based on the related code of law, market structure and technical architecture, which together enable and constrain most human activity systems in an attempt to balance inherent conflicts and pursue the common good. In a general sense, infrastructures are designed to promote fairness, wealth and operational efficiency. TEMPLATE CULTURE Much has been written about the general nature of infrastructures elsewhere, leaving no need to reiterate it here. Instead, let us elaborate on the generative capability of infrastructure as an additional area of concern that should be considered particularly in the context of developing infrastructure requirements for open design. In view of the generative character of design in general, and open design in particular, developing an appropriate infrastructure should aim to incorporate the structural features that are most conducive to creative processes and products. Building on the concept of generative design, I suggest a set of generalizable considerations for designing such infrastructures. More specifically, I propose that the infrastructure of open design should be evocative, engaging, adaptive, and open.

      Generative design refers to the design considerations in developing an array of artefacts and interactions that support and enhance generative capacity – that is, the considerations in designing systems that are conducive to the ability of a person or group to produce new configurations and possibilities, to reframe the way we see and understand the world, and to challenge the normative status quo.¹ People’s generative capacity is a key source of innovation; by definition, generative design aims to encapsulate the design directives that enhance and complement that human capability.

      In general, generative capacity refers to having an evocative power or aptitude that can result in producing or creating something, or tapping into a source of innovation. In the context of open design infrastructure, the modifier ‘generative’ denotes that the noun it modifies is conducive to the production of something innovative or the discovery of new and hitherto unknown design alternatives. In other words, generative design refers here to the design requirements and considerations in developing open design infrastructures – that is, the related code of law, market structure and technical architecture – that augment people’s natural ability to innovate. Subsequently, four top-level design directives are suggested for infrastructures, as follows:

       Generative infrastructure is evocative

      Generative infrastructure inspires people to create something unique. It evokes new thinking and enables them to translate their ideas into a new context. The infrastructure can help to create the environment or conditions that are prone to those insights by generating and juxtaposing diverse frames that are not commonly associated with one another within an underlying context. Systemic features that drive evocative design enable, for example, seeing an object or situation from multiple perspectives, testing it in multiple situations, examining it at multiple degrees of granularity, and exploring multiple overlay configurations.

       Generative infrastructure is engaging

      Generative infrastructure is enchanting and holds the attention of people by inducing their natural playfulness and ‘flow experience’. The infrastructure TEMPLATE CULTURE can help in the creation of engaging environments or platforms that stimulate the users’ cognitive spontaneity and playfulness as well as overall positive affect state, thus encouraging further exploration, tinkering and experimentation. Systemic features that drive engaging design enable, for example, fostering positive affect and high spirit that stimulate a state of ‘joie de vivre’, activating cognitive spontaneity induced by playfulness, and stirring up curiosity through intriguing challenges.

       Generative infrastructure is adaptive

      Generative infrastructure is flexible and conducive to effective use by a heterogeneous set of people in their own respective environments and for various tasks within an intended scope. It can be adapted with respect to the type of users or groups that it serves in diverse problem spaces. It is also simple to understand and easy for anyone to master. The infrastructure can help in the creation of adaptive systems or platforms that are flexible yet powerful enough to enable the generation of a continuous stream of new ideas and configurations. Systemic features that drive adaptive design enable, for example, user-induced tailoring and customization to meet situated
