#1132: Warrantimer

Normally, product warranties tend to be limited by the period for which an item has been in use.

Today’s invention is to provide a warranty based on the number of times which a product (or some subsystem) has been used.

This could be made to work in products such as washing machines, by counting electronically the number of door openings or wash cycles undertaken.

The memory device used to record these data would have to built so as to detect any attempt to interfere with its sensor wiring but, once created, it could be embedded in a generic armoured casing and applied to many different systems.

This type of device could be reprogrammed to give eg a variable warranty period for remanufactured or pre-owned products.
