What must be considered regarding the function of a product to ensure its durability?

Considering the conditions under which the product will be used is crucial for ensuring its durability. Durability refers to the ability of a product to withstand wear, pressure, or damage over time. By understanding the specific environment and uses the product will be subjected to, designers can select appropriate materials, design features, and construction methods that enhance its longevity.

For example, a product intended for outdoor use must be resistant to factors such as moisture, UV exposure, and temperature extremes. In contrast, a product designed for indoor use might prioritize other aspects such as weight or fragility. Evaluating the expected conditions allows designers to anticipate potential stresses and failures, ensuring the product remains functional over its intended lifespan. This thorough consideration helps mitigate risks related to product performance and customer satisfaction.
