Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tensile support is wrapped around the electromagnets, then the electromagnets are supported during transportation, but the arrangement does not provide sufficient rotational restraint and is difficult to configure to achieve small tolerances for spatial location
Solution Approach 1:
The support structure is divided into multiple discrete support elements (first support element, second support element, third support element) rather than a single continuous support. Each support element can be independently positioned and adjusted, enabling precise spatial location while providing comprehensive restraint against translation and rotation.
Solution Approach 2:
Different support elements are positioned at specific locations around the electromagnet coil with different orientations. The first support element restrains movement in a first direction, the second in a second direction, and the third in a third direction, providing localized restraint qualities tailored to specific movement vectors.
2Reliability
If a tensile support is wrapped around the electromagnets, then the electromagnets are supported during transportation, but the arrangement may not provide sufficient rotational restraint to effectively manage transportation loads
Solution Approach 1:
Different support elements are positioned at specific locations around the electromagnet coil with different orientations. The first support element restrains movement in a first direction, the second in a second direction, and the third in a third direction, providing localized restraint qualities tailored to specific movement vectors.
Solution Approach 2:
The support elements are arranged asymmetrically around the coil rather than uniformly. The first support element is positioned at a first location, the second at a second location, and the third at a third location, with each oriented to restrain movement in a specific direction, creating an asymmetric configuration that provides comprehensive rotational restraint.
