Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional vertical disks with multiple grooves and protrusions are used for fastening, then the buckle device can provide fastening function, but the structure becomes complex and difficult to assemble
Solution Approach 1:
The patent divides the fastening system into separate modular components: a latch plate with simple fastening elements and a buckle body with corresponding receiving structures. This segmentation allows each component to be simple and easy to manufacture, while collectively providing the required fastening function, eliminating the need for complex vertical disks with multiple grooves and protrusions.
Solution Approach 2:
The patent extracts the fastening function from the complex vertical disk structure and implements it through simpler dedicated components. The latch plate contains the essential fastening elements, while the buckle body provides the receiving and locking mechanisms, separating concerns and reducing overall structural complexity.
2Reliability
If electromagnetic rods interfere with vertical disks to prevent release, then the buckle device can prevent accidental release, but the press body can still be pressed causing occupant uneasiness
Solution Approach 1:
The patent introduces a detector as an intermediary component that monitors the state of the electromagnetic rod and latch plate interaction. The control unit uses this detection information to intelligently control the electromagnetic rod, enabling it to distinguish between intentional pressing (for release) and accidental forces, thus preventing accidental release while allowing intentional operation.
Solution Approach 2:
The patent implements a feedback mechanism where the detector continuously monitors the position and state of the electromagnetic rod and latch plate, and this information is fed back to the control unit. The control unit adjusts the electromagnetic rod's state based on this feedback, ensuring that the locking mechanism remains engaged during normal operation but can be properly released when intended.
3Adaptability or versatility
If vertical disks are set in the middle with long rotating shafts, then the buckle device can provide rotation mechanism, but the rotating shafts are easily deformed due to external forces
Solution Approach 1:
The patent replaces the mechanical rotation mechanism with long rotating shafts that are prone to deformation with an electromagnetic actuation system. The electromagnetic rod, controlled by electromagnetic force, performs the locking and unlocking functions without requiring long mechanical shafts, thereby eliminating the strength and deformation issues while maintaining the necessary adaptability for operation.
Solution Approach 2:
The patent extracts the rotation function from the mechanical shaft system and replaces it with electromagnetic actuation. The electromagnetic rod can be actuated linearly to achieve the same functional effect as rotation, eliminating the need for vulnerable rotating shafts while maintaining operational versatility.
4Ease of operation
If multiple protrusions are provided on vertical disks to limit rotation angle, then the buckle device can control movement, but the protrusions are tiny to wear out leading to accidents
Solution Approach 1:
The patent replaces the mechanical protrusion-based movement control system with an electromagnetic control system. The electromagnetic rod's position and state are controlled by electromagnetic force and monitored by a detector, eliminating the need for small protrusions that are susceptible to wear. This substitution maintains precise movement control while dramatically improving reliability.
5Reliability
If latch plate device is directly fastened by electromagnetic rods, then the buckle device can provide fastening, but the pulling force is obviously insufficient
Solution Approach 1:
The patent merges multiple fastening mechanisms within the buckle body structure. In addition to the electromagnetic rod, the buckle body includes a latch plate receiving structure, detection mechanisms, and control systems that work together to provide robust fastening. This combination of mechanisms distributes and amplifies the holding force, ensuring sufficient pulling force capacity that exceeds the limitation of electromagnetic rod direct fastening alone.

AI summary
A buckle device comprises a main body unit, a latch unit and a fastening unit. The main body unit includes a housing surrounding and defining an accommodating space, two first apertures provided in the housing, two slider blocks arranged in the accommodating space, and two first elastic bodies abutting against the slider blocks. The latch unit includes a tongue element and two tongue openings provided on the tongue element. The fastening unit includes two bolt bodies passing through the first apertures, and two second elastic bodies abutting against the bolt bodies. When the tongue element is separated from the two slider blocks, the two slider blocks are pushed by the two first elastic bodies, and the two bolt bodies is pushed against by the two slider blocks. When the tongue element is in contact with the two slider blocks, the two slider blocks are pushed by the tongue element, and the two bolt bodies are pushed into the two tongue openings by the two second elastic bodies, so that the tongue element can be securely fastened. Accordingly, the external pulling force of the tongue element can be increased, and the structure of the buckle device can be effectively improved.
