Solution Overview
Problem
Existing closure devices for attaching objects to vehicle frames, such as bicycles, are not easily adaptable for various objects and lack a secure, space-efficient design that is cost-effective and easy to use.
Innovation Solution
A closure device with a first closure part featuring multiple locking pieces and magnetic elements, and a second closure part with locking receptacles and a locking mechanism, allowing for magnetic attachment and a positive frictional connection, facilitated by an actuating mechanism that adjusts locking elements to ensure secure engagement and easy detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closure device uses multiple locking pieces and locking receptacles to ensure secure connection, then the reliability of attachment is improved, but the device complexity increases
Solution Approach 1:
The closure device is divided into multiple independent locking pieces and locking receptacles, each capable of engaging separately. This segmentation allows the device to achieve reliable multi-point connection without requiring a single complex locking mechanism, thereby improving reliability while keeping individual components simple
Solution Approach 2:
The locking pieces and locking receptacles are designed with universal functionality where each locking piece can engage with its corresponding receptacle independently. This multi-functional design allows the same basic locking mechanism to be replicated multiple times, achieving secure connection through redundancy rather than complexity
2Ease of operation
If magnetic elements are used to assist placement of closure parts, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
Magnetic elements are introduced to replace or assist manual alignment operations. The magnetic attraction between corresponding elements in the closure parts automatically guides and holds the parts in correct positioning during assembly, eliminating the need for precise manual alignment while adding only a simple magnetic component
Solution Approach 2:
The magnetic elements provide self-aligning and self-holding functionality during the closing operation. The closure parts automatically attract and position themselves correctly through magnetic interaction without requiring external assistance or complex mechanical alignment mechanisms
3Volume of moving object
If the locking device is designed with minimal installation space, then the volume of the locking device is reduced, but the ease of operation deteriorates
Solution Approach 1:
The locking mechanism components are arranged in a nested or compact configuration where smaller elements are positioned within or adjacent to larger ones. The locking pieces and receptacles are integrated into the closure parts bodies, minimizing the overall envelope volume while maintaining full operational functionality
Solution Approach 2:
The locking mechanism utilizes the closing direction as the primary dimension for operation, with magnetic elements providing attraction along this axis. This dimensional focus allows the device to achieve full locking functionality within a compact volume by concentrating mechanical and magnetic interactions along the closing path rather than requiring lateral space
4Reliability
If the closure device uses both magnetic elements and positive locking sections, then the reliability of attachment is improved, but the manufacturing cost increases
Solution Approach 1:
The magnetic elements and positive locking sections are combined in a complementary manner where each performs a specific function. The magnetic elements provide attraction and alignment, while the locking pieces and receptacles provide mechanical interlocking. This merging of magnetic and mechanical systems achieves high reliability through functional complementarity rather than redundancy, optimizing manufacturing efficiency

AI summary
A locking device (2) for connecting two assemblies comprises a first locking part (4) having at least two locking pieces (41A, 41B) each with a locking section (410) and at least one first magnetic element (43A, 43B), and a second locking part (5) having at least two locking receptacles (51A, 51B) and at least one second magnetic element (43A, 43B). Additionally, the locking device has a locking mechanism (52) arranged on the second locking part (5), which has at least two locking elements (524, 527) and an actuating mechanism operatively connected to the locking element (524, 527), wherein the locking elements (524, 527) can be brought into operative contact with the locking sections (410) of the locking pieces (41A, 41B) in a closed position in order to establish a positive locking or friction locking connection between the first locking part (4) and the second locking part (5).
