system to deliver the modular benefits. Modular systems could be viewed as more complete or holistic design whereas platforms systems are more reductionist, limiting modularity to components. Complete or holistic modular design requires a much higher level of design skill and sophistication than the more common platform system. Cars, computers, process systems, solar panels, wind turbines, elevators, furniture, looms, railroad signaling systems, telephone exchanges, pipe organs, synthesizers, electric power distribution systems and modular buildings are examples of platform systems using various levels of component modularity. For example, one cannot assemble a solar cube from extant solar components or easily replace the engine on a truck or rearrange a modular housing unit into a different configuration after a few years, as would be the case in a modular system. The only extant examples of modular systems in today's market are some software systems that have shifted away from versioning into a completely networked paradigm. Modular design inherently combines the mass production advantages of standardization with those of customization. The degree of modularity, dimensionally, determines the degree of customization possible. For example, solar panel systems have 2-dimensional modularity which allows adjustment of an array in the x and y dimensions. Further dimensions of modularity would be introduced by making the panel itself and its auxiliary systems modular. Dimensions in modular systems are defined as the effected parameter such as shape or cost or lifecycle. Mero systems have 4-dimensional modularity, x, y, z, and structural load capacity. As can be seen in any modern convention space, the space frame's extra two dimensions of modularity allows far greater flexibility in form and function than solar's 2-d modularity. If modularity is properly defined and conceived in the design strategy, modular systems can create significant competitive advantage in markets. A true modular system does not need to rely on product cycles to adapt its functionality to the current market state. Properly designed modular systems also introduce the economic advantage of not carrying dead capacity, increasing the capacity utilization rate and its effect on cost and pricing flexibility. In vehicles Aspects of modular design can be seen in cars or other vehicles to the extent of there being certain parts to the car that can be added or removed without altering the rest of the car. A simple example of modular design in cars is the fact that, while many cars come as a basic model, paying
