Design defects refer to flaws in a product's design that make it unsafe or ineffective for its intended use. These defects can arise from poor planning, inadequate testing, or failure to consider user needs. When a product is designed with inherent issues, it can lead to malfunctions or accidents, potentially causing harm to users. In legal terms, design defects can result in liability for manufacturers under product liability laws. This means that if a product causes injury due to its design, the company responsible for the product may be held accountable. Understanding design defects is crucial for ensuring safety and compliance in industries like automotive, electronics, and consumer goods.
