Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the buckle structure is used for installing optical filters on UAV lenses, then the filter can be installed and removed, but the buckle structure is prone to wear out during assembly and disassembly, leading to unreliable connections
Solution Approach 1:
The patent replaces the traditional mechanical buckle structure with a magnetic field-based fastening system. The magnetic field exerts attractive force on ferromagnetic materials to secure the filter in place, eliminating the need for complex buckle mechanisms. This substitution resolves the contradiction by providing reliable connection through magnetic attraction while simplifying assembly and disassembly operations.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the mounting structure and the filter. The magnetic field acts as a mediator that provides secure attachment without direct mechanical contact, thereby preventing wear of mechanical components while maintaining reliable connection. This intermediary approach allows easy assembly and disassembly without compromising connection reliability.
2Adaptability or versatility
If the buckle structure is used for installing optical filters, then the filter can be mounted on the lens, but the connection strength is not strong and reliable enough
Solution Approach 1:
The patent replaces the weak mechanical buckle connection with a magnetic field-based fastening system. The magnetic attraction force provides significantly stronger and more reliable connection than the buckle structure, while maintaining the ability to mount and remove filters. This substitution directly addresses the insufficient connection strength while preserving adaptability.
Solution Approach 2:
The patent changes the fundamental parameter of connection from mechanical interlocking to magnetic attraction. By utilizing magnetic field strength as the connecting parameter instead of mechanical engagement, the system achieves much stronger connection force while maintaining ease of operation. This parameter change resolves the contradiction between mounting capability and connection strength.
3Ease of operation
If the buckle structure is used for filter installation, then the filter can be attached to the lens, but the buckle may be damaged or dead-locked during disassembly and assembly
Solution Approach 1:
The patent replaces the mechanical buckle system with a magnetic field-based fastening mechanism. This substitution eliminates the buckle components that are prone to damage and deadlocking. The magnetic field provides secure attachment during operation but allows easy removal when needed, preventing structural damage while maintaining operational ease.
Solution Approach 2:
The magnetic field serves as an intermediary that provides temporary secure attachment without creating permanent mechanical stress or deformation. This intermediary approach prevents damage to the mounting structure while allowing easy assembly and disassembly, resolving the contradiction between operational ease and structural integrity.
4Ease of operation
If the buckle structure is used for filter installation, then the filter can be mounted on the lens, but the disassembly and assembly is easy to wear out the buckle structure, which affects the tightness of the installation
Solution Approach 1:
The patent replaces the mechanical buckle system with a magnetic field-based fastening system. This substitution eliminates the wear problem inherent in mechanical buckles, ensuring consistent installation tightness over time. The magnetic field provides uniform and repeatable attachment force, maintaining manufacturing precision while allowing easy assembly and disassembly operations.
Solution Approach 2:
The magnetic field acts as an intermediary that provides consistent and uniform attachment force without mechanical wear. This intermediary mechanism ensures that installation tightness remains stable over repeated assembly and disassembly cycles, resolving the contradiction between ease of operation and manufacturing precision.
