Solution Overview

Problem

Existing test handlers for graphics chips often result in performance deviations between test results and actual performance when the graphics chip is used in a commercial graphics card.

Innovation Solution

A test handler for graphics chips that includes a loading unit, an unloading unit, a test unit, and a buffer unit, where the test unit uses a commercial graphics card identical to a practically used card and a contact unit to connect the graphics chip for testing, thereby simulating the actual usage environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a test handler uses a replicated test graphics card to perform tests on graphics chips, then the test process can be completed, but the test results show performance deviation from actual usage in commercial graphics cards

Engineering Contradiction:

Improvetest result accuracyVSAvoidperformance consistency with actual usage

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The patent uses a commercial graphics card (identical to practical usage) instead of a replicated test card to perform tests. This copying of the actual usage environment ensures that test results accurately reflect real-world performance, eliminating the performance deviation issue while maintaining test validity

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The contact unit serves as an intermediary component that connects the graphics chip to the commercial graphics card. This mediator enables the graphics chip to be tested within the actual commercial graphics card environment, ensuring test conditions match usage conditions while allowing the chip itself to remain the test subject

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If a commercial graphics card is used in the test unit to test graphics chips, then performance deviation is reduced, but the device complexity increases

Engineering Contradiction:

Improveperformance evaluation accuracyVSAvoidtest unit structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The commercial graphics card serves multiple functions: it acts as both the test environment and the reference standard for performance evaluation. By using the actual commercial graphics card for testing, the system eliminates the need for separate replicated test cards and calibration equipment, reducing overall device complexity while improving measurement precision

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The commercial graphics card tests graphics chips by utilizing its own inherent architecture and performance characteristics. The card essentially tests compatible chips against itself, eliminating the need for external replicated test equipment and reducing system complexity while maintaining high measurement accuracy

Inventive Principle:

Principle #25Self-service
