Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different components and assembly procedures are used for various connector types (FC, SC, LC, ST), then each connector type can be optimized for its specific characteristics, but manufacturing costs increase due to higher raw material costs and production complexity

Engineering Contradiction:
Improveconnector type compatibilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by designing a single housing unit with a standardized coupling unit that can accommodate multiple connector types (FC, SC, LC, ST) through modular components. The coupling unit includes a hollow seat and biasing member that can be configured to support different connector specifications, eliminating the need for separate dedicated components for each connector type and thereby reducing manufacturing costs while maintaining adaptability.

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

Solution Approach 2:

The patent segments the connector into distinct modular components: a housing unit and a coupling unit. The coupling unit is further segmented into a hollow seat, coupling seat, core tube, and biasing member. This segmentation allows for flexible reconfiguration of components to match different connector types while using the same basic manufacturing processes and tooling, thus reducing manufacturing complexity and cost.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple types of components and assembly procedures are used for different connector types, then specific connector characteristics can be achieved, but the number of manufacturing and assembly procedures increases

Engineering Contradiction:
Improveconnector specification adaptabilityVSAvoidassembly procedure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The universal coupling unit design allows a single assembly procedure to produce multiple connector types. The hollow seat and biasing member can be configured with different dimensions or features to accommodate FC, SC, LC, or ST connectors, but the assembly process remains standardized, reducing procedure complexity while maintaining specification adaptability.

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

Solution Approach 2:

The biasing member is designed to be adjustable or reconfigurable to provide different biasing forces or positions depending on the connector type being assembled. This dynamic adjustability allows the same coupling unit to adapt to different connector specifications without requiring separate assembly procedures for each type.

Inventive Principle:
Principle #15Dynamics
