Solution Overview

Problem

Conventional optical modules require complex unlocking mechanisms that often rely on springs or resilient members, which can lead to fatigue and permanent deformations during repeated plugging, and lack simplicity in installation and operation.

Innovation Solution

A self-sinking unlocking mechanism using a rotating lug and pull ring system, where the pull ring generates torque to drive the support rod and rotating lug, allowing for traction force to rotate the lug towards the upper cover, eliminating the need for springs and simplifying the unlocking process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional unlocking mechanisms use springs or resilient members, then the unlocking function can be achieved, but fatigue and permanent deformations occur during repeated plugging

Engineering Contradiction:

Improveunlocking mechanism stabilityVSAvoidservice life of resilient members

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent removes springs and resilient members from the unlocking mechanism, extracting the problematic elastic components that cause fatigue. The self-sinking unlocking is achieved through geometric design of the rotating lug and support rod interaction, eliminating the need for elastic recovery elements.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The unlocking mechanism uses the rotational motion of the rotating lug itself to generate the unlocking action through the support rod. The system is self-powered by the user's rotation action, eliminating the need for separate biasing members or energy storage components.

Inventive Principle:

Principle #25Self-service

2Reliability

If conventional unlocking mechanisms use springs or resilient members, then the unlocking function can be achieved, but the structure becomes complex and requires additional biasing members

Engineering Contradiction:

Improveunlocking mechanism stabilityVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex elastic components (springs, resilient tabs, biasing members) from the traditional unlocking mechanism. Only rigid components (rotating lug, support rod, pull ring) remain, dramatically simplifying the structure while maintaining reliability.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using elastic deformation to achieve unlocking (conventional approach), the patent inverts the approach by using rigid geometric interaction where the rotating lug's rotation directly drives the support rod to create the unlocking motion through mechanical leverage.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If conventional unlocking mechanisms are used, then the optical module can be unlocked, but friction and stress on components increase during operation

Engineering Contradiction:

Improveunlocking operation smoothnessVSAvoidfriction and stress on components

Core Design Contradiction:

Ease of operationVSForce

Solution Approach 1:

The patent employs curved surfaces and rounded geometries in the rotating lug and support rod contact areas, reducing friction during rotation and sliding. The curved interfaces allow smoother relative motion compared to sharp-edged rigid contacts.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The unlocking mechanism uses dynamic rotational motion of the rotating lug to continuously change the contact points and force directions during the unlocking process, distributing stress over time and reducing peak forces on any single component.

Inventive Principle:

Principle #15Dynamics
