AI Technical Summary

Technical Problem

In the existing technology, fragile tags are easily damaged during the normal use of electronic devices, which may lead to misjudgment of whether the user has disassembled the device and make it difficult to accurately determine the responsibility for the damage.

Method used

The device employs a disassembly detection system, which includes a base plate, a vibrator, a sensor, a carrier, balls, a waveguide, and a magnetic component. It senses whether the casing has been opened by detecting vibration signals and determines whether the casing has been disassembled by using the arrangement of the balls.

Benefits of technology

Accurately determine whether the casing of electronic devices has been opened by the user, avoid misjudgment, ensure the accuracy of liability attribution, and make it difficult for users to conceal their disassembly behavior.

Abstract

A disassembly detection device is disposed within a housing, the housing comprising a lower housing and an upper housing. The disassembly detection device includes: a base plate for fixing within the lower housing; a vibrator disposed on the base plate; a sensor disposed on the base plate; a carrier disposed between the vibrator and the sensor, and including a plurality of receiving slots; a plurality of balls arranged in a predetermined pattern within the receiving slots, wherein the number of balls is less than the number of receiving slots; a waveguide contacting the balls; and a magnetic element disposed on the waveguide and fixed within the upper housing. When the upper housing and the lower housing are separated, the waveguide moves away from the carrier, and the magnetic element attracts the balls to the waveguide.
