Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a cell phone is used as a fiber inspection tool without additional magnification components, then the device complexity is low and ease of manufacture is high, but the measurement precision and visual magnification capability are insufficient

Engineering Contradiction:
Improvevisual magnification capabilityVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent implements nesting by placing the magnification lens system within the protective housing that already contains the cell phone mounting structure. The lens assembly is nested inside the housing module, allowing the magnification function to be integrated without significantly increasing external device dimensions or complexity. This enables improved measurement precision while maintaining relatively simple device structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent introduces adjustable focus mechanisms that allow dynamic adjustment of the magnification lens position relative to the fiber end face. This dynamic adjustment capability enables users to optimize visual magnification for different inspection scenarios, improving measurement precision while the adjustability is achieved through simple mechanical means that do not greatly increase device complexity.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If manual focus adjustment mechanisms are added to the housing module, then the ease of operation is improved, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveease of operationVSAvoidease of manufacture
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent replaces complex electronic autofocus systems with simple manual focus adjustment mechanisms. The focus adjustment is achieved through manual rotation of the housing module or adjustment of lens position, which provides ease of operation through direct user control while avoiding the manufacturing complexity of electronic actuators, motors, and control systems. This mechanical approach improves ease of operation while maintaining ease of manufacture.

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

3Adaptability or versatility

If interchangeable fiber connector sockets are provided for different fiber types, then the adaptability is improved, but the device complexity and number of components increase

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universality by designing the housing module with interchangeable fiber connector sockets that can accommodate different fiber connector types (SC, LC, ST, etc.). The same basic housing structure and magnification lens system serve multiple functions by supporting various connector types, providing adaptability without requiring separate inspection devices for each fiber type. This multi-functionality approach improves adaptability while keeping device complexity manageable through standardized design.

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

AI summary

The purpose of this continuation is to increase the viewing magnification of the already issued patent U.S. Pat. No. 11,385,412 B2. By the addition of a module housing that has the capability of allowing for additional magnification, lighting and focusing capabilities. A module housing case is described. The modular housing case includes a fiber optic component housing defined as a cavity and or cavities that are sized to receive a fiber optic connector and or connectors. Within the cavity or cavities is a ferrule guide or ferrule guides. The module housing case also has an internal cavity that is at least partially enclosed. Components to assist in magnification may be disposed at least partially or fully within the internal cavity. Those components can range from a lighting system powered by internal electronics or a system that relies on the cell phone camera flash and or flashlight LED for internal fiber end face lighting. Finally, the module housing case employs a camera lens alignment feature that can be adjusted manually to increase magnification of the field of view by the raising and or lowering of the module housing case.
