Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional clamping mechanisms are used to fix display modules, then the detection system can handle standard-shaped modules, but it cannot accommodate special-shaped or large-angle modules without risking damage

Engineering Contradiction:

Improveadaptability to different display module shapesVSAvoidrisk of damage to display modules

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses a suction nozzle connected to a negative pressure assembly to create a vacuum field that adsorbs the display module. This pneumatic mechanism replaces traditional mechanical clamps, allowing secure holding of various shapes including special-shaped and large-angle modules without physical contact that could cause damage.

Inventive Principle:

Principle #29Pneumatics and hydraulics

Solution Approach 2:

The invention substitutes the mechanical clamping system with a pneumatic adsorption system. The suction nozzle generates negative pressure to hold the display module, eliminating the need for physical clamps that could damage special-shaped or large-angle modules during detection and transfer.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If display modules are separately crimped to respective detection devices, then each device can detect its module, but detection efficiency decreases due to repeated crimping operations

Engineering Contradiction:

Improvedetection efficiencyVSAvoidtime for repeated crimping operations

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The carrier platform with suction nozzle serves as a universal holding device that can accommodate multiple display modules of different shapes. The platform transfers modules between detection devices without requiring separate crimping operations for each device, thereby improving detection efficiency and reducing time loss.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The carrier platform acts as an intermediary device between detection devices. It holds display modules and transfers them between devices, eliminating the need for repeated crimping operations at each detection device and thereby improving overall detection efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If traditional clamping mechanisms are used, then the structure is simple, but the carrier platform lacks versatility for different module shapes

Engineering Contradiction:

Improveversatility for different module shapesVSAvoidcomplexity of carrier platform structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The carrier platform incorporates a suction nozzle connected to a negative pressure assembly, using pneumatic principles to achieve versatile holding of different module shapes. This adds functional complexity but maintains structural simplicity through the use of standard pneumatic components.

Inventive Principle:

Principle #29Pneumatics and hydraulics
