What is a defectively designed product?

When the design of a product is inherently dangerous or defective, the product was defectively designed and can lead to a claim brought by injured parties. These claims would be brought against the party who designed the product, not the manufacturer, because the danger did not arise from an error or mishap that occurred during the manufacturing process. Instead, the claim is based on the theory that all of the products in the line are inherently dangerous. These products are dangerous even though they were manufactured properly, in according to the correct specifications.

Three Types of Defectively Designed Products

Now that you understand the legal definition of a defectively designed product, it is important to understand what defectively designed products look like in real life. The following are three examples:

  • A car model that is likely to flip over when rounding a corner.
  • A pair of sunglasses that fails to protect eyes from ultraviolet rays.
  • A line of electric blankets that leads to electrocution of the user if it is turned up to the “high” setting.


In order to succeed in a claim for a defectively designed product, you must be able to show that your injury was specifically caused by the defective design. For example, if you are driving a care that is prone to flipping over, but you are injured because you were involved in a crash with another vehicle, you will not succeed in a defective design claim unless you can show that the crash was caused by the car being in the process of flipping at the time of the crash.
