Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate connectors or adapters are used for optical and electrical signal transmission, then each signal type can be transmitted reliably, but the physical layout becomes complicated and operational convenience deteriorates

Engineering Contradiction:
Improvesignal transmission reliabilityVSAvoidphysical layout complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines optical signal transmission (via optical transceiver module) and electrical signal transmission (via conductive terminals) into a single adapter body. The main body simultaneously accommodates both the optical transceiver module and conductive terminals, allowing both signal types to be transmitted through one integrated component rather than requiring separate connectors, thereby simplifying the physical layout while maintaining reliable transmission of both signal types

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adapter is designed as a multi-functional device that can handle both optical and electrical signals simultaneously. The single adapter structure serves multiple purposes: providing mechanical support, enabling optical signal transmission through the optical transceiver module, enabling electrical signal transmission through conductive terminals, and providing unified positioning and engagement features, thereby replacing what would traditionally require multiple specialized connectors

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

2Adaptability or versatility

If multiple separate connectors are used for different signal types, then each connector can be optimized for its specific function, but the number of components increases and ease of operation deteriorates

Engineering Contradiction:
Improvesignal transmission capabilityVSAvoidoperational convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges multiple connection functions into a single adapter assembly. The main body integrates both the optical transceiver module and conductive terminals, allowing users to connect both optical and electrical signals simultaneously through one mating operation rather than requiring multiple separate connection steps, thereby significantly improving ease of operation while maintaining full adaptability for different signal types

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adapter is designed as a universal interface that handles multiple signal types through a single connection point. The integrated structure provides unified positioning features, engagement mechanisms, and signal transmission paths for both optical and electrical signals, making the device easier to operate while preserving the specialized functionality needed for different signal types

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