Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing technologies are used to secure sensors in open loop magnetic cores, then the device complexity is reduced, but the measurement precision deteriorates due to sensor displacement
Solution Approach 1:
The securing structure is divided into multiple independent clamp components (first clamp component and second clamp component) that can be separately positioned and adjusted. Each clamp component independently secures the sensor at specific locations, allowing precise positioning without requiring a complex monolithic structure. This segmentation enables accurate sensor placement while keeping individual clamp components relatively simple.
Solution Approach 2:
The elasticity components serve as intermediaries between the clamp components and the magnetic core. These elastic elements provide flexible connection and positioning, allowing the clamps to securely hold the sensor while accommodating minor variations in core dimensions. The intermediary elastic components absorb positioning errors and maintain stable sensor placement without requiring extremely precise manufacturing tolerances.
2Measurement precision
If the magnetic core shifts positions, then the device adaptability is tested, but the measurement precision deteriorates due to sensor displacement
Solution Approach 1:
The clamp components are designed with dynamic positioning capability through the elasticity components. When the magnetic core shifts position, the elastic elements can deform and adjust the clamp positions accordingly, maintaining continuous contact and secure holding of the sensor. This dynamic adaptation allows the structure to accommodate core movement while preserving measurement accuracy, rather than requiring a completely rigid fixed-position system.
Solution Approach 2:
The elasticity components allow for parameter changes in the form of deformable connection between the clamps and the magnetic core. The elastic elements can change their physical state (deformation) in response to core position changes, maintaining the securing function across different positions. This parameter flexibility enables the structure to adapt to position variations while keeping the sensor securely positioned for accurate measurement.
3Measurement precision
If multiple clamp components are used to secure the sensor, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The first and second clamp components work together as a coordinated system to secure the sensor. By combining multiple simple clamp structures with elastic elements, the system achieves stable sensor positioning that would be difficult with a single complex clamp. The merging of multiple simple components creates a robust positioning system that is more reliable than a single complex mechanism, improving precision while keeping individual components simple.

Function Achieved in This Case
The structure effectively reduces sensor displacement, ensuring accurate measurement of magnetic fields and current levels, while also grounding the open loop magnetic core to improve electromagnetic compatibility and interference performance.
Implementation Method 1
a first elasticity component connected to the first end, where the first elasticity component extends in a direction away from the body... a second elasticity component connected to the second end, where the second elasticity component extends in a direction away from the body... the structure is compressible in response to an application of force applied to the outer surface of the first elasticity component and the outer surface of the second elasticity component
Implementation Method 2
Sensors are often used to determine a level of current passing through an open loop magnetic core. For example, a sensor may determine the level of current by measuring a magnetic field
