Magnetic Anchoring Device With Force Measurement
Solution Overview
Problem
Magnetic anchoring devices face reliability issues when attached to walls with varying surface conditions, such as non-flat surfaces, damage, rust, or coatings, leading to unpredictable magnetic forces and potential detachment under load, posing safety risks.
Innovation Solution
A magnetic anchoring device comprising multiple magnet units with a force generating device and a force measuring device to apply and measure a test force perpendicular or parallel to the wall, ensuring the anchoring device can withstand external forces without detachment, using a combination of permanent, electromagnets, and electropermanent magnets with a yoke and attachment structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a magnetic anchoring device is used to attach to a wall structure, then the anchoring device can be easily installed and removed, but the attachment reliability becomes unpredictable due to varying surface conditions
Solution Approach 1:
The patent applies preliminary action by measuring the magnetic attracting force before actual use to determine if the anchoring device can withstand required loads. This pre-assessment ensures reliable attachment by verifying that the magnetic force is sufficient prior to climbing or loading, thereby resolving the contradiction between easy installation and reliable attachment.
2Reliability
If the magnetic anchoring device is designed for strong magnetic force, then the attachment reliability improves, but the device complexity increases due to multiple magnet units and control systems
Solution Approach 1:
The patent applies segmentation by dividing the magnetic anchoring device into multiple independent magnet units that can be attached at different locations on the wall structure. Each magnet unit contributes to the overall magnetic force, and the system can function with multiple smaller units rather than requiring one large complex magnet, thus maintaining reliability while managing device complexity.
3Adaptability or versatility
If the wall structure surface has variations such as non-flat surfaces, damage, rust, or coatings, then the adaptability to different environments improves, but the magnetic attracting force becomes unpredictable
Solution Approach 1:
The patent applies feedback by incorporating a measuring device that directly measures the magnetic attracting force between the magnet unit and the wall structure surface. This real-time measurement provides feedback on the actual magnetic force, allowing the system to account for surface variations and ensure the force is sufficient for safe operation, thereby resolving the unpredictability caused by diverse surface conditions.
