Solution Overview

Problem

Existing optical cable connection modules face issues with shutter separation, allowing alien substances to enter the module body and disrupting smooth signal transmission due to the shutter's tendency to exit the U-shaped insertion grooves during opening and closing.

Innovation Solution

The optical cable connection module incorporates a cover with protruding members that cross the U-shaped insertion grooves, preventing the shutter's rotating shaft from separating from the grooves, and a wedge-shaped elastic member that adheres to the shutter's top surface to maintain contact with the cover's protrusions, ensuring the shutter remains within the grooves during operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the shutter is made to rotate freely in the U-shaped insertion grooves for easy opening and closing, then the ease of operation is improved, but the shutter frequently separates from the cable insertion hole allowing alien substances to enter

Engineering Contradiction:

Improveease of shutter opening and closingVSAvoidalien substance entry through cable insertion hole

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cover acts as an intermediary component between the shutter and the external environment. It includes a protrusion that fits into the U-shaped insertion groove, creating a controlled interface that prevents the shutter from separating while still allowing rotational movement for opening and closing operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The solution divides the protective function into two parts: the cover provides the barrier against alien substances, while the protrusion-insertion groove mechanism provides the constraint to prevent separation. This segmentation allows each component to perform its specific function effectively.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the shutter is constrained within the U-shaped insertion grooves to prevent separation, then the reliability is improved, but the ease of operation for opening and closing is reduced

Engineering Contradiction:

Improveshutter retention in cable insertion holeVSAvoidease of shutter opening and closing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The protrusion on the cover serves as a mediator that enables controlled movement. It maintains contact with the shutter during rotation while allowing the shutter to move freely enough for easy opening and closing operations, thus balancing reliability and ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system transitions from a static constraint to a dynamic interaction. The protrusion on the cover dynamically follows the shutter's rotation, providing continuous contact and prevention of separation while allowing smooth rotational movement for easy operation.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the upper part of the U-shaped insertion grooves is left open for shutter rotation, then the ease of operation is improved, but the manufacturing precision is compromised due to frequent separation

Engineering Contradiction:

Improveease of shutter rotationVSAvoidshutter position stability in cable insertion hole

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The cover with its protrusion acts as an intermediary that maintains precise positioning of the shutter during rotation. The protrusion fits into the U-shaped insertion groove to prevent separation while allowing smooth rotational movement, thus maintaining both ease of operation and manufacturing precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The solution segments the functional requirements: the cover provides the precision constraint through its protrusion, while the U-shaped insertion groove provides the rotational freedom. This segmentation allows each component to optimize for its specific function.

Inventive Principle:

Principle #1Segmentation
