Solution Overview

Problem

The increasing demand for heat dissipation and miniaturization in protective cage assemblies of receptacle connectors poses challenges in efficiently arranging light guide pipes, which occupy significant space and require innovative solutions to optimize component placement.

Innovation Solution

A protective cage assembly design where the light guide pipe extends along the inner wall of the cage, with portions inside and outside the cage, minimizing space usage and allowing for efficient heat dissipation components to be integrated.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the light guide pipe is arranged in the protective cage assembly, then the light signal transmission function is achieved, but the space occupied in the cage increases

Engineering Contradiction:
Improvelight signal transmissionVSAvoidspace occupied in cage
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The light guide pipe is nested along the inner wall of the cage, with its first portion extending into the cage interior and its second portion extending outward. This nested arrangement allows the light guide pipe to utilize the wall space efficiently, transmitting light signals while occupying minimal volume within the cage structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The light guide pipe transitions from a conventional centralized arrangement to a wall-following configuration, utilizing the vertical dimension along the cage's inner wall. This dimensional repositioning allows the light guide pipe to extend along the perimeter rather than consuming central space, thereby achieving space optimization.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Temperature

If heat dissipation components are added to the protective cage assembly, then heat dissipation capability is improved, but the device complexity increases

Engineering Contradiction:
Improveheat dissipation capabilityVSAvoidcomponent arrangement complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The cage structure serves multiple functions: it provides mechanical protection, guides light signals through the integrated light guide pipe, and acts as a heat dissipation component. By making the cage multi-functional, additional heat dissipation features can be incorporated without proportionally increasing overall device complexity.

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

Solution Approach 2:

The light guide pipe is merged with the cage structure, where the first portion is positioned along the inner wall and integrated into the cage's geometric framework. This merging allows the light guide function and structural function to coexist, creating space for heat dissipation components without requiring separate dedicated spaces.

Inventive Principle:
Principle #5Merging (Combining)

3Volume of stationary object

If the protective cage assembly is miniaturized, then the overall device size is reduced, but the arrangement difficulty of components increases

Engineering Contradiction:
Improvecage volumeVSAvoidcomponent arrangement difficulty
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The light guide pipe is segmented into multiple portions: a first portion extending into the cage, a second portion extending outward, and optionally a third portion passing through the wall. This segmentation allows the light guide function to be distributed along the cage perimeter, reducing the need for large centralized spaces and facilitating miniaturization while maintaining functional integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The light guide pipe is positioned locally along specific regions of the cage's inner wall rather than occupying the entire central volume. This localized arrangement optimizes space utilization in different zones of the miniaturized cage, allowing heat dissipation components to be placed in remaining spaces without increasing overall complexity.

Inventive Principle:
Principle #3Local quality
