Magnetic Ball Closure for Detachment Under Full Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices fail to securely detach a first part from a second part under full load and allow relative movement between the parts in the closed position, making them impractical for applications requiring reliable attachment and detachment in various fields such as sports, seafaring, and industry.
Innovation Solution
A closure device featuring a spherical engagement part with a magnetic unit and a sliding unit that reduces the recess size to securely hold the engagement part, enabling detachment under full load and allowing up to 360° rotation or 45° pivoting for relative movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device uses a pin and locking element mechanism for detachable connection, then the device provides basic locking functionality, but the first part cannot be separated from the second part under full load
Solution Approach 1:
The patent applies the dynamics principle by making the recess size variable through a sliding unit that can move between locked and unlocked positions. When the sliding unit moves to the unlocked position, the recess size increases, allowing the spherical engagement part to be removed even under full load. This dynamic adjustment of the recess size resolves the contradiction between maintaining strong locking force and enabling detachability under load.
Solution Approach 2:
The patent applies the parameter changes principle by changing the size parameter of the recess. The sliding unit modifies the recess dimensions from a smaller locked state (providing strong holding force) to a larger unlocked state (allowing removal under load). This parameter change enables the system to transition between strong locking and easy detachment states, resolving the contradiction between locking reliability and detachability.
2Stability of the object's composition
If a locking device holds parts firmly in closed position, then connection stability is improved, but relative movement between parts is prevented
Solution Approach 1:
The patent applies the dynamics principle by introducing a spherical engagement part that can rotate and pivot within the recess while maintaining connection stability. The spherical shape allows dynamic movement (360° rotation or 45° pivoting) without compromising the locked state, resolving the contradiction between stability and movement capability.
Solution Approach 2:
The patent applies the spheroidality principle by using a spherical engagement part instead of a rigid fixed connector. The spherical geometry inherently provides rotational freedom while maintaining positional engagement, enabling both stable connection and relative movement simultaneously.
3Reliability
If a locking device uses complex engagement mechanisms, then connection reliability is improved, but device complexity increases
Solution Approach 1:
The patent applies the segmentation principle by dividing the locking device into distinct functional units: a first locking unit with a spherical engagement part, a second locking unit with a recess, and a sliding unit for size adjustment. This segmentation allows each component to perform its specific function simply, reducing overall complexity while maintaining reliability.
Solution Approach 2:
The patent applies the mechanics substitution principle by replacing complex mechanical locking mechanisms with a simpler system based on magnetic attraction forces. The magnetic unit provides holding force without requiring complex interlocking parts, reducing mechanical complexity while maintaining connection reliability.

AI summary
The invention relates to a closing device (100) for releasably connecting a first part to a second part. The closing device (100) has a first closing unit (200) comprising a spherical engaging part (201), and has a first retaining device (202) for attaching the first part. The closing device also comprises a second closing unit (300) which has a second retaining device (302) for attaching the second part, and comprises a cut out (304), which is delimited by a wall (303), for receiving the spherical engaging part (201), wherein the cut out (304) has an opening (305) for inserting the spherical engaging part (201). In addition, a sliding unit (311) is located in the cut out (304), said sliding unit (311) being preloaded in the direction of the opening (305), and the sliding unit (311) can be displaced into an open position and a closed position. In the open position of the sliding unit (311), the spherical engaging part (201) can be received in the cut out (304). In the closed position of the sliding unit (311), the spherical engaging part (201) abuts both the wall (303) and the sliding unit (311) and is clampingly held. The spherical engaging part (201) is magnetic. A magnetic unit (306) is located in the cut out (304).
