Bar Exam — MBE (Multistate Bar Exam)TortsMedium

A product manufacturer designed a new line of blenders. During the design phase, engineers chose a type of plastic for the blender's pitcher that was known to become brittle and shatter if exposed to extreme temperatures, despite a safer, slightly more expensive alternative plastic being available. The blenders were marketed for general kitchen use. A consumer suffered severe lacerations when the pitcher shattered while blending hot soup. Which type of product defect is most likely present?

  1. AWarning defect
  2. BAssembly defect
  3. CDesign defect
  4. DManufacturing defect
Show answer & explanation

Correct answer: C. Design defect

A design defect occurs when the product is dangerous because of its design, even if manufactured perfectly. Here, the choice of a brittle plastic for a blender pitcher that might be used with hot liquids, when a safer alternative existed, points to a flaw in the product's design.

Why the other options are wrong

  • A. While a warning might have been absent, the fundamental problem is the product's dangerous design, not just a failure to warn.
  • B. An assembly defect is a type of manufacturing defect, where components are put together incorrectly.
  • D. A manufacturing defect would mean a deviation from the intended design, but here the design itself is flawed.

Design Defect (Products Liability)

A product defect where the product is unreasonably dangerous as designed, even if perfectly manufactured.

  • Can be proven by the consumer expectation test or the risk-utility test.
  • Risk-utility test considers feasibility and cost of safer alternative designs.
  • Applies to the entire product line.

Memory trick: Made Defectively, Designed Dangerously, Warned Weakly.
