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) Notable bridge collapse


 * Ford_Pinto Pinto fuel tank litigation

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.
 * Atlantic_Southeast_Airlines_Flight_2311


 * Citigroup_Center Skyscraper built without consideration for diagonally-oriented "quartering winds".

Huygens_(spacecraft) 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.
 * Huygens probe radio built without consideration of Doppler shift.

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 The impetus for airliners to use rounded windows, rather than rectangular windows.


 * Revolving_door The reason for book-fold emergency operation of revolving doors.


 * Electrical_muscle_stimulation The Relax-a-cizor


 * IKEA The IKEA Malm dresser

* 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.
 * Mark_14_torpedo A US World War II torpedo had four major flaws.

Here is one not currently found on Wikipedia:


 * The Windows 95/98 bug which hangs the system after 49.7 days of uptime

Finally, the reason no one in Hartford, Connecticut was called for grand jury duty for three years:
