Solution Overview
Problem
Existing connecting apparatuses face challenges in providing a simple, comfortable, and secure attachment method that allows for position-tolerant connection and easy disengagement of parts, while ensuring a loadable grip and accommodating rotational movements.
Innovation Solution
A connecting apparatus featuring a first connecting part with a blocking portion and a second connecting part that can be rotated and tilted to engage and disengage, utilizing magnetic devices for attachment and a unique engagement mechanism where the engagement direction is transverse to the closing direction, allowing for secure locking and easy release through tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the engagement direction is different from the closing direction, then the connection is more position-tolerant and comfortable for users, but the structure becomes more complex with additional blocking portions and engagement mechanisms
Solution Approach 1:
The patent introduces a blocking portion that extends in a direction different from both the closing direction and engagement direction, creating a three-dimensional engagement geometry. This additional spatial dimension allows the engagement protrusion to guide the connecting part during closing while the blocking portion prevents accidental disengagement, achieving position tolerance without significantly increasing operational complexity
Solution Approach 2:
The engagement protrusion acts as an intermediary element between the first and second connecting parts. It provides a guided engagement path that mediates the closing motion, ensuring proper alignment and positioning while the blocking portion mediates the disengagement prevention. This intermediary mechanism achieves position tolerance through geometric guidance rather than complex control systems
2Productivity
If magnetic devices are used to assist attachment along the closing direction, then the attachment process is simplified and accelerated, but the magnetic force may interfere with the engagement protrusion alignment
Solution Approach 1:
The magnetic devices perform preliminary action by attracting the connecting parts together along the closing direction before the engagement protrusions engage. This preliminary magnetic attraction brings the parts into proximity and initial contact, after which the engagement protrusions take over to provide precise alignment and final securement. The geometric design of the engagement protrusions ensures they guide the final positioning, preventing magnetic interference from compromising alignment precision
3Adaptability or versatility
If the second connecting part is made rotatable about the closing direction, then the adaptability and comfort for users are improved, but the stability of the connection may be reduced
Solution Approach 1:
The patent implements a dynamic connection system where the second connecting part can rotate about the closing direction to accommodate different orientations and user preferences. The engagement protrusion and blocking portion are designed to maintain secure engagement throughout the rotational range, providing stability in each positioned state. The magnetic devices continue to provide holding force during rotation, ensuring the connection remains stable while adapting to different orientations

AI summary
A connecting apparatus includes a first connecting part, which has a first basic body and at least one engagement protrusion arranged rigidly on the first basic body, and a second connecting part, which is attachable to the first connecting part in a closing direction and which has a second basic body with an engagement portion arranged rigidly on the second basic body. The first connecting part has a first magnetic device and the second connecting part has a second magnetic device. The first magnetic device and the second magnetic device interact in a magnetically attracting manner along the closing direction to assist the attachment of the first connecting part and the second connecting part to each other. The first connecting part has a blocking portion which is designed, in the connected position, to interact with the second connecting part in order to block the engagement of the engagement portion with the at least one engagement protrusion counter to an engagement direction. In the connected position, the second connecting part is rotatable about the closing direction with respect to the first connecting part. In the event of rotation, the engagement of the engagement portion with the at least one engagement protrusion and the blocking of the engagement by the blocking portion remains.
