Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a single testing apparatus is used to test all device features, then the quantity of testing apparatuses is reduced, but the device complexity increases

Engineering Contradiction:

Improvequantity of testing apparatusesVSAvoidcomplexity of testing apparatus

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The testing apparatus is designed with multi-functional capabilities to perform various tests on different device features using a single integrated system. The robotic arm can execute different test procedures (touchscreen testing, button pressing, audio testing, camera testing) by loading different test programs, eliminating the need for multiple specialized testing apparatuses while consolidating functionality into one versatile device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The testing apparatus employs a nested structure where the robotic arm operates within a test bench environment, and the device under test is positioned within a gripping head that is part of the robotic arm system. This nested arrangement allows multiple functional components to be integrated in a compact configuration, reducing the overall quantity of separate apparatuses needed.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the robotic arm is made highly movable and rotatable to access all device features, then the versatility of testing increases, but the positioning precision becomes more difficult to achieve

Engineering Contradiction:

Improveversatility of testing coverageVSAvoidpositioning precision of robotic arm

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system performs preliminary actions by first obtaining information about the device to be tested, then using this information to select an appropriate test procedure and determine the precise location of the device on the test bench. The robotic arm's movements are calibrated based on this pre-determined location information, allowing the system to achieve precise positioning despite having multiple degrees of freedom for versatility.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The testing apparatus incorporates feedback mechanisms where the system determines the location of the device, uses this information to select test procedures, and then executes tests based on this feedback. This closed-loop approach ensures that the robotic arm can achieve precise positioning by continuously adjusting its movements based on location determination feedback from the system.

Inventive Principle:

Principle #23Feedback

3Productivity

If multiple test procedures are integrated into one apparatus, then the productivity of testing increases, but the difficulty of operating and selecting appropriate tests increases

Engineering Contradiction:

Improveproductivity of testing processVSAvoidease of selecting test procedures

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The testing apparatus employs self-service functionality by automatically obtaining information about the device to be tested and using this information to autonomously select the appropriate test procedure. The system can identify device features and determine which tests to perform without requiring manual configuration by the operator, thereby maintaining ease of operation while integrating multiple test procedures into a single automated workflow.

Inventive Principle:

Principle #25Self-service
