VSEngineering 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

Engineering Contradiction:
Improvemeasurement capability for different component typesVSAvoidnumber of measuring devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

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

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.

Inventive Principle:

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

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

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.

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

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.

Inventive Principle:

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.
