Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If custom fixtures are created for each measurement module, then measurement modules can be mounted, but the process becomes costly and time-consuming

Engineering Contradiction:

Improvemeasurement module mountingVSAvoidfixture creation and switching time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The probe card fixture is designed with a universal mounting interface that can accommodate multiple different measurement modules through interchangeable adapters. The fixture body includes a standard manipulator interface and multiple adapter receptacles, allowing a single fixture to serve multiple measurement module types without requiring custom fixtures for each module.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting system is divided into modular components: a fixed fixture body, interchangeable adapters, and measurement modules. Each adapter is designed to interface with the standard fixture body while providing specific mounting configurations for different measurement module types, enabling quick switching without replacing the entire fixture.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple custom fixtures are maintained for different measurement modules, then module switching is possible, but operational efficiency decreases

Engineering Contradiction:

Improvemeasurement module switching capabilityVSAvoidoperational efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

A single probe card fixture body is designed to universally mount multiple measurement modules through standardized adapter interfaces. The fixture includes multiple adapter receptacles positioned at different locations and orientations, allowing operators to quickly switch between measurement modules by simply changing adapters rather than replacing entire fixtures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The mounting system enables dynamic reconfiguration by allowing adapters to be quickly attached and detached from the fixture body. This dynamic capability permits rapid switching between different measurement module configurations during operation, significantly improving operational efficiency compared to static custom fixtures.

Inventive Principle:

Principle #15Dynamics

3Manufacturing precision

If custom fixtures are created for each measurement module, then specific mounting configurations are achieved, but costs increase

Engineering Contradiction:

Improvemounting configuration precisionVSAvoidfixture production cost

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The fixture body is manufactured as a single universal component with standardized mounting interfaces and multiple adapter receptacles. This universal design eliminates the need to manufacture separate custom fixtures for each measurement module, significantly reducing production costs while maintaining precise mounting configurations through the standardized interface geometry.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of changing the physical structure of the fixture body for different measurement modules, the system changes the adapter component parameters. Each adapter is designed with specific geometric parameters to achieve the required mounting configuration for different measurement modules, while the main fixture body remains unchanged, reducing manufacturing complexity and cost.

Inventive Principle:

Principle #35Parameter changes
