Design validation (DV) and product validation (PV) hold significant roles in multiple industries, such as the manufacturing of electronic components and, notably, in the automotive sector. In these fields, due to continuous innovation and strict safety requirements, the design and manufacturing processes need meticulous validation. These tests ensure that new products meet both technical specifications and user expectations.

In the automotive industry, validation test systems are particularly critical. The collaboration between original manufacturers and suppliers is vital for a successful validation process. Components can be categorized into two types: original equipment and those designed by suppliers. The former are tested by the manufacturers using various testing systems and methods, with set procedures, equipment, and testing cycles. Supplier-designed components, however, are usually tested by the suppliers and these results are often not published, leading to cautions against using non-original parts.

DV and PV tests not only aim to guarantee the final quality of the product but also facilitate early identification of potential issues during the manufacturing process. This significantly reduces the risks and increases the chances of market success. Thus, this type of validation is not just a technical necessity but also a strategic tool in the competitive market.

Let’s delve into what design validation entails!

Design validation testing (DV): bridging theory and practice

Design validation tests are critical in ensuring that ideas conceived at the drawing board endure under real-world conditions. This process not only verifies the technical feasibility of the designed product but also predicts its market success.

During the process, developers and engineers utilize a prototype to check if the product truly meets the functional requirements set during the design phase. It’s not enough for the product to look good on paper or in computer simulations; DV testing seeks to confirm if it functions in real life as imagined.

Key goals and features of DV tests

The primary aim of design validation tests is to ascertain the product’s performance, functionality, and reliability under actual conditions. The results of these tests are crucial for the success of the product's market introduction, as identifying and correcting flaws early can happen before mass production.

Common DV testing methods in the automotive industry

Design validation testing is vital for the development of safe and reliable vehicles in the automotive industry. Let’s explore some frequently used testing methods:

• Functional and Performance Tests: These tests evaluate how well a vehicle performs under real road conditions, assessing aspects like engine performance, the effectiveness of the braking system, and the vehicle's dynamic attributes.
• Mechanical Testing: Customized tests such as strength and impact resistance tests illuminate critical details that can affect vehicle safety in the event of an accident.
• Electrical Tests and EMC Evaluations: Testing electrical components and systems is crucial, along with electromagnetic compatibility (EMC) testing to ensure that the vehicle's electrical systems do not interfere with one another.
• Chemical Exposure and Material Testing: These tests examine materials’ resistance to corrosion and exposure to various chemicals.
• Environmental and Climate Tests: Additional tests like thermal shock tests or testing in different climates are also pivotal for simulating real usage conditions.

A successful and effective design validation is essential for ensuring the reliability, safety, and eventual market success of vehicles. A well-executed DV testing strategy allows manufacturers to confidently enter the market, knowing their products meet the highest industry standards and expectations.
