Solution Overview
Problem
Conventional attaching and detaching apparatuses suffer from misalignment between plates and holders due to manufacturing errors, leading to partial contacts and inconsistent positioning, which affects the accuracy and reliability of machining processes.
Innovation Solution
An attaching and detaching apparatus with a first and second mounting plate, connected by a connecting member featuring protrusions and holes that ensure precise alignment through a surface of revolution contact, allowing for accurate positioning and separation to prevent damage from impact forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spheres and recessed surfaces are used for connection, then the attaching and detaching function is achieved, but misalignment occurs due to manufacturing errors resulting in partial contacts
Solution Approach 1:
The invention replaces spherical connection elements with planar contact surfaces that have a specific geometric relationship (one surface is a plane, the other is a spherical surface with radius of curvature equal to or larger than the distance between plates). This curvature design ensures that even with manufacturing errors, the contact occurs at a unique point rather than partially, eliminating misalignment while maintaining the attaching and detaching function through magnetic attraction.
2Object-affected harmful factors
If magnets are used for attracting force, then the machining head can be separated during collision, but positioning accuracy is reduced due to partial contacts
Solution Approach 1:
By designing one contact surface as a plane and the other as a spherical surface with radius of curvature equal to or larger than the distance between plates, the invention ensures unique point contact. This eliminates the partial contact problem that causes positioning inaccuracies, while the magnetic attraction force still provides adequate protection against impact forces during collisions.
3Ease of operation
If spheres project toward recessed surfaces, then connection is achieved, but the positional relationship varies after separation and reconnection
Solution Approach 1:
The geometric design where one surface is a plane and the other is a spherical surface with radius of curvature equal to or larger than the plate distance ensures that contact always occurs at a unique, well-defined point. This eliminates the variability in positional relationships that occurs with spherical connectors, allowing consistent and reproducible positioning after separation and reconnection operations.

AI summary
An attaching and detaching apparatus includes a main mounting plate to which a main mounting object is to be mounted, an attachment mounting plate to which an attachment mounting object is to be mounted, and a connecting member between the main mounting plate and the attachment mounting plate. A protrusion projecting toward the connecting member is formed on the main mounting plate. A hole into which the protrusion fits is formed on the connecting member. A first contact surface in the shape of a surface of revolution is formed on the protrusion. A second contact surface in the shape of a surface of revolution is formed on the inner surface of the hole. The first contact surface and the second contact surface are in contact with each other with the central axis of the protrusion coinciding with the central axis of the hole.
