Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional adapting devices are used for interface conversion, then interface compatibility is improved, but device complexity and cost increase due to one-to-one conversion requirements

Engineering Contradiction:
Improveinterface compatibilityVSAvoidconversion complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal transceiving device that can handle multiple transceiving specifications (HDMI, USB-C, PCIe, etc.) through a single interface. The device classifies incoming information based on its characteristics and converts it to appropriate formats for different output interfaces, eliminating the need for multiple dedicated converting devices. This multi-functional approach resolves the contradiction by improving interface compatibility while reducing overall system complexity.

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

Solution Approach 2:

The patent introduces an intermediary transceiving device that acts as a mediator between different transceiving specifications. This device receives information from one interface type, classifies it according to information characteristics, and then transmits it through optical fibers to appropriate receiving devices. The intermediary approach allows heterogeneous interfaces to communicate without requiring direct one-to-one conversion pairs, thereby reducing complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If optical fibers are used for long-distance transmission, then transmission stability is improved, but the number of fiber converters increases and cost increases

Engineering Contradiction:
Improvetransmission stabilityVSAvoidnumber of fiber converters
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple fiber conversion functions into a single transceiving device. Instead of having separate fiber converters for each transceiving specification (HDMI, USB-C, PCIe), the device integrates all conversion functions into one unit that can handle multiple specifications simultaneously. This combining approach maintains transmission stability through optical fiber while significantly reducing the number of fiber converters needed in the system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The transceiving device is designed with universal functionality to support multiple transceiving specifications through a single optical fiber connection. The device can classify and convert different types of information (video, audio, data) according to their characteristics and transmit them through the same optical fiber infrastructure, eliminating the need for multiple specialized fiber converters and reducing system complexity.

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

3Adaptability or versatility

If multiple transceiving specifications are supported, then adaptability is improved, but synchronization problems occur during data transmission

Engineering Contradiction:
Improveinterface supportVSAvoidsynchronization
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements preliminary classification of information based on its characteristics before transmission. The transceiving device identifies the type of information (video, audio, data) and its required transmission parameters in advance, then applies appropriate conversion and synchronization settings. This preliminary action ensures that each type of information is handled with the correct synchronization parameters, maintaining reliability while supporting multiple specifications.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent dynamically changes transmission parameters based on the classified information characteristics. Different information types (HDMI video, USB-C data, PCIe signals) are transmitted with appropriately adjusted parameters such as bandwidth allocation, timing synchronization, and protocol conversion. This parameter adaptation allows the system to maintain synchronization across multiple transceiving specifications by optimizing transmission settings for each information type.

Inventive Principle:
Principle #35Parameter changes
