Multi-Level Coil Support for Accurate Cassette Coil Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Accurate measurement of the thickness and width of concentrated wound cassette coils is challenging due to their slanted lamination and low rigidity, which causes deformation and misalignment during clamping, making precise dimensioning difficult.
Innovation Solution
A coil holding apparatus with multiple supporting parts of varying heights and an adjustment mechanism to match the coil's slant, ensuring the coil is laid flat and securely fixed to prevent slanting and deviation, allowing precise measurement of dimensions.

Engineering Contradiction Analysis
1Measurement precision
If the coil is clamped for measurement, then the measurement process can be performed, but the coil deforms and becomes misaligned due to low rigidity
Solution Approach 1:
The supporting part is divided into multiple supporting surfaces at different positions (first supporting surface, second supporting surface, third supporting surface) with different heights. This segmentation allows each surface to support a specific portion of the coil's lower surface, distributing the support forces and preventing deformation while maintaining measurement accuracy.
Solution Approach 2:
Each supporting surface is designed with specific local properties: the first supporting surface is positioned below the thickness measurement contact point, the second supporting surface is positioned at a specific lateral location, and the third supporting surface prevents rotational movement. This local differentiation of support functions prevents overall coil deformation while enabling precise measurement.
2Ease of operation
If the coil is laid on a flat surface, then it can be accessed for measurement, but it becomes slanted due to spiral winding structure
Solution Approach 1:
The supporting part uses an asymmetric configuration of supporting surfaces at different heights rather than a symmetric flat surface. The first supporting surface is at a different height than the second and third supporting surfaces, creating an asymmetric support structure that matches the coil's slanted geometry and prevents slanting during measurement.
Solution Approach 2:
The solution moves from a two-dimensional flat surface support to a three-dimensional multi-level support structure. By adding the vertical dimension with supporting surfaces at different heights, the apparatus can accommodate the coil's slanted geometry while maintaining stable positioning for accurate measurement.
3Measurement precision
If multiple supporting surfaces are used to prevent slanting, then measurement accuracy improves, but the device complexity increases
Solution Approach 1:
Multiple supporting surfaces (first, second, and third supporting surfaces) are merged into a single integrated supporting part. This consolidation achieves the complex function of preventing slanting and deformation through multiple support points while maintaining a relatively simple overall structure that does not require multiple separate components.
