Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical fastener is used to retain the securing device, then the securing device can be held in position, but dirt and detritus accumulate around the fastener head making removal difficult and time-consuming
Solution Approach 1:
The patent replaces the mechanical fastener system with a magnetic field-based retention system. The magnet housed in the casing creates magnetic attraction forces that hold the securing device in position without requiring mechanical fasteners that accumulate dirt. This substitution eliminates the problem of dirt accumulation around fastener heads while maintaining reliable retention.
Solution Approach 2:
The patent extracts the magnet from the traditional mechanical fastener assembly and houses it within a protective casing. This extraction allows the magnetic retention mechanism to operate independently from mechanical fastening components, eliminating the need for accessible fastener heads that become caked with dirt and difficult to remove.
2Reliability
If mechanical fasteners or clips are used, then the securing device can be retained in position, but the installation and removal processes become time-consuming and cumbersome
Solution Approach 1:
The patent replaces time-consuming mechanical fastening operations with rapid magnetic engagement. The magnet creates immediate magnetic attraction when the securing device is inserted into the passageway, eliminating the need for threading fasteners or manipulating clips. Removal is equally simplified by reversing the magnetic engagement, significantly reducing installation and removal time.
3Reliability
If a magnet is housed in a casing, then the magnet can be protected and positioned, but the magnet needs to be moveable to form magnetic coupling for holding the casing in position
Solution Approach 1:
The patent implements a dynamic magnet system where the magnet can move between an initial position (when the casing is inserted) and a working position (where magnetic coupling is formed). This movement allows the magnet to engage with the second object and create the necessary magnetic attraction for retention, while still being constrained within the casing to maintain proper positioning and protection.

AI summary
There is described a securing device (10) for releasably securing a first object to a second objection. The device comprises a casing (12) and a coupling magnet (22) housed in the casing. The casing is configured for being inserted in a passageway formed by aligned openings (54, 60) of the first and second objects when assembled together, for blocking separation of the first object and the second object from one another. The coupling magnet (22) is moveable from an initial position to a working position to form a magnetic coupling for holding the casing in the passageway. The first and second objects can respectively be a tooth (50) of a mining or excavation bucket and an adaptor (52) of the bucket for the tooth (50). A fixed magnet (28) can be provided in the casing (12), the fixed magnet (28) being oppositely poled with respect to the coupling magnet (22) for damping the movement of the coupling magnet to its working position. There is also provided a removal tool (178) for removal of the securing device from its securing position. The removal tool includes a coupling magnet (180) for being moved from a retracted position to a coupling position for magnetically coupling with the securing device (10) for releasing the coupling magnet (22) of the securing device from its working position and withdrawal of the securing device.
