Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If non-contact optical connections are integrated on tactical rails and accessories, then data transfer efficiency and communication capability are improved, but device complexity increases due to the integration of TOSA and ROSA assemblies

Engineering Contradiction:
Improvedata transfer efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical contact-based electrical connections with non-contact optical connections using TOSA and ROSA assemblies. This substitution enables data transfer without physical contact, improving reliability and transfer efficiency while eliminating wear and corrosion issues associated with mechanical contacts

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The tactical rail system is enhanced to serve multiple functions: it provides mechanical support for accessories, electrical power delivery through contacts, and optical data communication through the integrated TOSA/ROSA assemblies. This multi-functionality allows a single rail structure to handle power, data, and control signals simultaneously

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

2Ease of operation

If non-contact optical connections are used for data transfer between accessories and firearm, then the need for physical connections is reduced, but alignment precision requirements increase to ensure sufficient optical signal transfer

Engineering Contradiction:
Improveease of accessory mountingVSAvoidalignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The TOSA and ROSA assemblies are integrated directly into the tactical rail structure, allowing the rail itself to provide alignment references and mechanical guidance. When accessories are mounted to the rail using standard mounting mechanisms, the optical connections automatically align without requiring additional adjustment procedures

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The optical connection interfaces are designed with standardized mounting positions and alignment features that ensure consistent geometric relationships between the TOSA/ROSA assemblies and accessory mounting points. This standardization creates predictable alignment conditions across different accessories and rail configurations

Inventive Principle:
Principle #12Equipotentiality
