Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If maintenance personnel climb or use cranes to attach rigging lines to anchor points, then the rigging line can be securely attached, but safety risks increase and efficiency decreases
Solution Approach 1:
The patent replaces the mechanical system of climbing and manual attachment with a magnetic field-based system. The magnetic anchor uses magnetic attraction forces to secure the rigging line to the work structure without requiring physical contact or manual manipulation at elevated positions, thereby eliminating safety risks associated with climbing and improving operational ease while maintaining secure attachment
Solution Approach 2:
The magnetic anchor serves as an intermediary element between the rigging line and the work structure. Instead of directly attaching the rigging line to the structure through manual labor or crane operations, the magnetic anchor mediates the connection through magnetic attraction, providing a safe and efficient intermediate step that eliminates the need for personnel to be at the anchor point
2Reliability
If maintenance personnel manually attach rigging lines to anchor points, then the attachment can be made, but time consumption increases and productivity decreases
Solution Approach 1:
The magnetic anchor system is self-attaching through magnetic attraction forces. Once the magnetic anchor is positioned near the work structure, it automatically secures the rigging line without requiring manual manipulation or complex attachment procedures, significantly reducing the time needed for attachment while maintaining secure connection
Solution Approach 2:
The magnetic anchor is pre-positioned on the transport vehicle before arriving at the work site. This preliminary positioning allows for rapid deployment at the actual anchor point, eliminating the need for time-consuming manual assembly or complex attachment procedures during the actual work task
3Ease of operation
If cranes or helicopters are used to transport and attach anchor points, then the anchor can be positioned at elevated locations, but equipment complexity and cost increase
Solution Approach 1:
The patent replaces complex mechanical lifting systems (cranes, helicopters) with a simple magnetic field-based attachment system. The magnetic anchor can be transported and attached using basic transport vehicles and manual handling, eliminating the need for heavy machinery while maintaining the ability to access and position anchors at elevated locations
Solution Approach 2:
The patent extracts the complex lifting and positioning functions from the attachment system. By separating the transport function (which can be performed by simple vehicles) from the attachment function (which is performed automatically through magnetic attraction), the system eliminates the need for complex cranes or helicopters while maintaining access to elevated positions
4Ease of operation
If magnetic anchors are used to attach rigging lines remotely, then safety and efficiency improve, but the magnetic force must be sufficiently strong to prevent slippage under load
Solution Approach 1:
The patent employs multiple magnetic anchors with adjustable positioning to optimize the magnetic connection strength. By varying the distance between the magnetic anchor and the work structure, and by using multiple anchors in parallel, the system achieves sufficient magnetic force to prevent slippage under load while maintaining remote attachment capability
Solution Approach 2:
The patent combines multiple magnetic anchors working together to achieve the required total holding strength. Instead of relying on a single magnetic anchor, the system merges multiple magnetic connection points, distributing the load across multiple magnetic forces, thereby ensuring sufficient strength to prevent slippage while maintaining the safety and efficiency benefits of remote attachment

AI summary
A magnetic anchor system, method, and device for attaching a rigging line to an elevated work structure. A transport vehicle may be used to position and attach at least one magnetic anchor to the elevated work structure, while being operated by a user at a safe location. Upon attachment of the magnetic anchor the strength of the magnetic connection of the primary magnetic anchor to the work structure is tested before anything is attached to a rigging line secured to the magnetic anchor.
