The Hidden Cost of Habits in Industrial Design

Costs as a Signal

In recent months, the cost of steel has once again become a recurring topic in manufacturing industry discussions. Price fluctuations, combined with ongoing tensions affecting global supply chains, have brought renewed attention to a raw material that represents a significant portion of product costs for many companies.

This dynamic affects different sectors in different ways. In highly standardized production environments, where volumes are high and margins are built on process repeatability, fluctuations in raw material prices can have immediate consequences. In other contexts — characterized by customized products, special-purpose machinery, or engineered-to-order solutions — the picture tends to be more complex.

In these cases, a change in an economic variable often provides an opportunity to examine a project from a broader perspective. Attention shifts from the material itself to the set of technical decisions that contribute to the final cost of a machine: materials, geometries, manufacturing processes, standardized components, customized parts, and production workflows.

Every change in context makes the weight of these decisions more visible over time. This is where the discussion gradually moves away from the price of steel and toward a topic that is closely connected to industrial design and its ability to evolve alongside the product.

Decisions That Remain Over Time

Industrial design is an evolutionary process. Every project originates within a specific technological, production, and economic context and is developed based on the knowledge available at that time.

As the years pass, many machines continue to evolve through targeted interventions: a functional modification, a new component, an adaptation requested by the market, or a customer-specific requirement. At the same time, some initial decisions remain unchanged and become an integral part of the product's identity. This is a natural phenomenon. Solutions that have proven reliable tend to become established over time and serve as a reference point for those who design, manufacture, and assemble the machine.

Meanwhile, the context continues to change. New materials become available, manufacturing technologies advance, certain components become more accessible, and some processes take on a different economic weight than they once had. For this reason, a machine designed ten or twenty years ago may still perform its function perfectly while containing solutions that deserve a fresh evaluation — not because they are wrong, but because the conditions that originally justified their adoption may have changed.

When a Solution Becomes a Habit

In day-to-day engineering work, it is common to encounter design choices that have gradually lost their connection to the original rationale behind their adoption.

A straightforward example involves customized manufacturing operations applied to covers or panels. In many cases, these solutions contribute to the product's visual identity and help define its appearance. Over time, however, a particular process may continue to be used simply because it has always been part of the design.

During several design review activities, we found ourselves analyzing components that required dedicated manufacturing operations, additional lead time, and more complex production management. Looking at the issue from an updated perspective revealed that standardized solutions already available on the market could deliver the same functional result while reducing production complexity and associated costs.

Situations like these are not unusual. More often, they are the result of a design path that has gradually consolidated through a series of small decisions made over time.

The presence of a design habit is not necessarily a problem. It becomes an interesting element to examine when economic conditions shift and place greater emphasis on the overall efficiency of the product.

Geometry, Components, and Complexity

When discussing industrial costs, material cost represents only one part of the equation.

Component geometry can significantly influence machining time. A particularly tight tolerance may require more complex manufacturing processes. An assembly composed of numerous dedicated parts can increase the number of operations required during production and assembly. Likewise, the choice between standard and custom-designed components can have a substantial impact on overall project management.

In highly standardized production environments, raw materials may represent the dominant cost factor, and price fluctuations directly affect margins. In special-purpose machinery and engineered-to-order systems, however, many other variables come into play. Engineering time, dedicated manufacturing operations, structural complexity, and production management can all become equally significant.

For this reason, cost analysis is most effective when the product is viewed as a system of interconnected elements rather than through the lens of a single cost category.

Industrial Design Through an Updated Perspective

Every design review requires balancing competing priorities. On one side lies the need to contain costs and complexity. On the other remains the fundamental objective of ensuring reliability, performance, and long-term durability.

In our experience, machine functionality is always the starting point. A technical solution must first satisfy the requirements it was designed to meet. Only then does it make sense to evaluate opportunities to simplify geometries, reduce component count, encourage standardization, or optimize specific manufacturing processes.

This approach makes it possible to address cost-related challenges without reducing the exercise to indiscriminate cost cutting. The objective is to understand which elements genuinely contribute to product value and which may warrant reconsideration in light of current conditions.

Industrial design should be grounded in precisely this capability: examining an existing system, understanding the logic behind it, and identifying opportunities for improvement while preserving the performance requirements that define the product.

Continuous Evolution of a Project

Rising steel prices are only one of many signals the market sends to manufacturing companies. Some have an immediate impact; others invite a different way of looking at the product.

Every project carries a history of technical decisions, production constraints, and choices that responded to specific needs at the time they were made. As time passes, those same decisions coexist with new materials, new technologies, and new market conditions.

The ability to periodically review a project extends beyond cost reduction. It is a way of ensuring that the product remains aligned with the context in which it operates.

In this sense, market changes can become a valuable opportunity to examine what has remained unchanged over time and assess whether more efficient paths exist to achieve the same result. It is a process of continuous renewal that accompanies the entire lifecycle of a machine and contributes to sustaining its competitiveness over the long term.
