1Measurement precision

If conventional measuring tools are used, then general measurement capability is available, but measurement precision for disc coil geometrical features is insufficient

Engineering Contradiction:
Improvemeasurement precisionVSAvoidadaptability
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The measuring tool is divided into specialized components: a rotatable support for holding the disc coil, movable carriers with position gauges for measuring specific geometrical features, and an angular position sensor. Each component performs a specific measurement function, enabling precise measurement of circularity, parallelism, and other geometrical features that general-purpose tools cannot measure accurately.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If specialized measuring tools for disc coils are designed, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvemeasurement precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The measuring tool is designed with multi-functional capabilities: the rotatable support can hold the disc coil for various measurement orientations, the position gauges can measure multiple geometrical features (circularity, parallelism, concentricity), and the control unit processes different measurement data types. This multi-functionality reduces the need for multiple specialized tools while maintaining measurement precision.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention replaces manual measurement methods with automated electronic measurement and data processing. Position gauges with electronic sensors automatically detect geometrical features, the angular position sensor provides precise rotational positioning data, and the control unit processes all measurement data electronically, eliminating the need for manual measurement and calculation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Extent of automation

If manual measurement methods are used, then device complexity is low, but measurement precision and automation level are insufficient

Engineering Contradiction:

Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The measuring tool performs self-measurement through automated data collection and processing. The position gauges automatically detect geometrical features as the disc coil rotates, the angular position sensor continuously provides rotational data, and the control unit automatically processes all measurements to determine circularity, parallelism, and other geometrical parameters without human intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control unit receives continuous feedback from position gauges and the angular position sensor during rotation, processes this data in real-time, and uses the feedback to calculate and display measurement results. This closed-loop feedback system ensures accurate and automated measurement of geometrical features.

Inventive Principle:
Principle #23Feedback
