Engineering Contradiction Analysis
1Adaptability or versatility
If multiple measuring devices with different electrode configurations are equipped to measure various electronic components, then measurement capability for different component types is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal measuring device that can measure multiple types of electronic components by dynamically adjusting the distance between device side electrodes. The control device selects appropriate electrode distances based on component type identification, allowing one measuring device to perform functions that would otherwise require multiple specialized devices. This reduces overall system complexity while maintaining versatility.
Solution Approach 2:
The measuring device employs dynamic adjustment of electrode spacing to adapt to different component types. The distance between device side electrodes can be changed based on the specific component being measured, enabling a single device to handle various component geometries and electrode configurations. This dynamic adaptability eliminates the need for multiple fixed-configuration measuring devices.
2Measurement precision
If extremely precise position control is implemented to bring device side electrodes into contact with component side electrodes, then measurement accuracy is improved, but device complexity and control difficulty increase
Solution Approach 1:
The patent replaces complex mechanical position control systems with a database-driven approach. Instead of relying on precise mechanical positioning, the system stores pre-calculated positional relationships between fiducial marks and component side electrodes in a database. The control device retrieves this information based on component type identification, significantly simplifying the control system while maintaining measurement precision.
Solution Approach 2:
The system performs preliminary actions by pre-storing the positional relationships between fiducial marks and component side electrodes in a database before actual measurement. This advance preparation eliminates the need for complex real-time calculation and positioning during measurement, reducing control complexity while ensuring accuracy.
3Ease of operation
If the size of the measuring device is reduced to match small electronic components, then ease of operation is improved, but measurement capability and electrode contact precision deteriorate
Solution Approach 1:
The patent applies local quality by providing magnified or enlarged views of the measurement area through imaging devices. While the overall device size remains compact for handling small components, the measurement region is optically magnified to allow precise positioning and contact. This enables the device to maintain both compactness for ease of operation and sufficient measurement precision through local optical enhancement.
