Talk:Product defect

Create a "List of design defects"?

Articles seem to minimize or even remove references to product defects.

Perhaps a notable list of product and design defects would make sense? Or already exists?

Here are ten significant ones, which presently can be found in sections of Wikipedia articles.

• Tacoma_Narrows_Bridge_(1940)#Cause_of_the_collapse Notable bridge collapse

• Ford_Pinto#NHTSA_investigation Pinto fuel tank litigation

• Atlantic_Southeast_Airlines_Flight_2311#Probable_cause Atlantic Southeast_Airlines Flight 2311

The crashed aircraft's left engine propeller blades went to 3 degrees instead of the commanded 79.2 degrees for feathering.

The design was ruled as defective.

• Citigroup_Center#Engineering_crisis_of_1978 Skyscraper built without consideration for diagonally-oriented "quartering winds".

• Huygens probe radio built without consideration of Doppler shift.

Huygens_(spacecraft)#Critical_design_flaw_partially_resolved

After Cassini's launch, it was discovered that data sent back from the probe to European Space Agency's mission control center was largely unreadable. It was found that the engineers had failed to allow for the doppler shift between the lander and the mother craft. Thus, Cassini's receiver would be unable to receive the data from Huygens during its descent to Titan.

A work-around was found to recover the mission. The trajectory of Cassini was altered to reduce the line of sight velocity and therefore the doppler shift. Cassini's subsequent trajectory was identical to the previously planned one, although the change replaced two orbits prior to the Huygens mission with three, shorter orbits.

• De_Havilland_Comet#Cohen_Committee_Court_of_Inquiry The impetus for airliners to use rounded windows, rather than rectangular windows.

• Revolving_door#Emergency_use The reason for book-fold emergency operation of revolving doors.

• Electrical_muscle_stimulation#Devices The Relax-a-cizor

• IKEA#Child_deaths The IKEA Malm dresser

• Mark_14_torpedo#Problems A US World War II torpedo had four major flaws.

* It tended to run about 10 feet (3 m) deeper than set.
* The magnetic exploder often caused premature firing.
* The contact exploder often failed to fire the warhead. (Especially when a direct hit, that is, perpendicular to the target)
* It tended to run "circular", failing to straighten its run once set on its prescribed gyro-angle setting, and instead, to run in a large circle, thus returning to strike the firing ship.

Here is one not currently found on Wikipedia:
