Engineering Thinking: The Core of China's Automotive

From Production Powerhouse to R&D Leader

Over the past few decades, China's automotive industry has achieved truly remarkable progress. From humble beginnings to becoming the world's largest automotive market by production and sales, we have manufactured countless products to be proud of. As the industry pioneer Meng Shaonong once wisely observed, building a large vehicle is primary school level, while building a compact vehicle is university level. By that measure, today's China automotive industry has certainly earned its university qualification.

However, behind these achievements, we must remain clear-eyed and honest about our challenges. The current state of the industry reveals a troubling imbalance: production technology has developed far faster than product R&D capability, and reverse engineering capability has far outpaced forward development capability. This lame duck phenomenon, if left unaddressed, will seriously constrain our transition from a large automotive nation to a truly strong one.

What Is Engineering Thinking?

Engineering thinking, in its simplest definition, means understanding a product from an R&D perspective — defining problems and finding answers through rigorous technical analysis. In the user's eyes, every product has three core attributes: function, functional safety, and functional durability. Users expect the product to work reliably under any condition throughout its entire lifecycle. Yet the current industry norm tends to focus overwhelmingly on function while paying insufficient attention to safety and durability, often to the point of serious neglect.

True engineering thinking requires us to return to the fundamentals of product R&D. It comprises three essential pillars: breadth of R&D, depth of R&D, and the R&D system itself.

Breadth of R&D: The 100-Page vs 12,000-Page FMEA Gap

In automotive R&D, FMEA is the core preventive tool for avoiding product failure and a key measure of R&D breadth. Through my work reviewing FMEA documents from numerous automotive component companies, I have observed enormous variation in their scope. Some are only a few pages. A few dozen pages is common. A hundred pages is already rare. But a world-class automotive ECU FMEA can run to over 12,000 pages of technical documentation.

The gap between 100 pages and 12,000 pages is precisely the gap between reverse engineering and forward development. It is the direct measure of the gap in product quality. The essence of FMEA is to uncover the complete set of technical problems. Only by systematically identifying and addressing every potential failure mode can the probability of product failure be minimized to the greatest extent. A 100-page FMEA can only scratch the surface. A 12,000-page FMEA demonstrates the depth of analysis required for truly robust products.

Depth of R&D: Analysis at the Micron Level

Consider the printed circuit board. A little-known but critical phenomenon is that from the moment electronic components are soldered, microscopic metal whiskers begin to grow. Over time, these whiskers lengthen and can eventually cause internal short circuits in the ECU, leading to catastrophic product failure in the field. Yet when a failed product is returned from the customer to the supplier, the vibration and impact during transport often break the delicate whiskers, and the failure mode mysteriously disappears. The engineer cannot reproduce the defect.

To fundamentally solve this class of problem, the research perspective must shift from the macroscopic centimeter scale to the microscopic micron scale. Engineers need to understand the growth mechanism of metal whiskers at the micron level, clarifying the complex relationships between growth rate, maximum length, material composition, and environmental conditions such as temperature and humidity. This is the depth of analysis that separates world-class engineering from superficial troubleshooting.

The R&D System: Bosch's Five Pillars and Safety-First Culture

Given the complexity and diversity of technical challenges, a robust R&D system is essential for systematic support. Bosch's product development system comprises five core elements: how to innovate effectively, how to conduct product R&D, how to manage knowledge and build capability, how to organize R&D activities, and how to provide R&D leadership.

From a product development culture perspective, safety is a non-negotiable attribute. At Bosch, the engineering iron law is clear: products must be sufficiently safe. If absolute safety cannot be achieved, the probability of risk must be reduced to an acceptably low level. If that is also not possible, extreme durability design must be employed to mitigate risk through the product's lifetime. And if none of these three conditions can be satisfied, the product design concept must be abandoned and reinvented from scratch. This uncompromising safety culture is the foundation upon which world-class automotive products are built.

Conclusion: The Path Forward

Engineering thinking is the deep understanding of a product from an R&D perspective. It comprises three essential elements: depth, breadth, and system. It means excavating the complete set of technical problems, transforming every unknown technical issue into a known one, and solving each one fundamentally at sufficient depth. This is not just a methodology — it is the essential path for China's automotive industry to complete its evolution from a large automotive nation into a truly powerful and innovative one.
