A design flaw or defect
exists when the product was designed with a defect that makes the entire line dangerous even if the manufacturing and assembly was flawless.
A manufacturing flaw or defect exists when a safely designed product becomes dangerous because the manufacturer failed to make the product in accordance with the plans and specifications.
Inadequate warnings or instructions are not complete and do not give clear directions for use of the product.
In some case, you may not necessarily have to prove that the manufacturer was “negligent”. Product liability claims, often called “strict product liability” can be established if you are able to prove three things
1. The product was defective.
2. The defect existed prior to the manufacturer releasing the product.
3. The defect caused your damages.
