Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing electrical connectors with paired caps and housing units face warpage issues due to increased contact count and dimensional enlargement, leading to improper linking during shipping and mounting.

Innovation Solution

A linking part with a rigid suction region is mounted on paired caps, spaced by standoffs for heat dissipation, and optionally a flexible tape is used to unify the connector units, ensuring proper alignment and retention during assembly and mounting on a printed circuit board.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pair of caps are assembled to paired housing units, then the connector can be mounted on printed circuit board, but warpage problem occurs due to increased contact amount and dimensional enlargement

Engineering Contradiction:

Improvemounting capabilityVSAvoidwarpage

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The connector is divided into paired housing units with corresponding caps, allowing independent assembly and mounting of each unit while maintaining overall structural integrity and reducing warpage through distributed contact points

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If paired caps are used without proper linking, then manufacturing is simpler, but the caps and socket units are not properly linked during shipping and mounting

Engineering Contradiction:

Improveassembly simplicityVSAvoidlinking reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

A linking part is introduced to merge the paired caps into a unified structure, ensuring they remain properly linked during shipping and mounting operations while maintaining manufacturing simplicity through modular design

Inventive Principle:

Principle #5Merging (Combining)

3Strength

If linking part is mounted close to caps, then structural rigidity is improved, but heat dissipation is blocked

Engineering Contradiction:

Improvestructural rigidityVSAvoidheat dissipation

Core Design Contradiction:

StrengthVSTemperature

Solution Approach 1:

The linking part is designed with localized rigid structures for structural support while incorporating heat dissipation features such as holes or thermal pathways in specific areas to maintain thermal management without compromising overall rigidity

Inventive Principle:

Principle #3Local quality

4Stability of the object's composition

If rigid linking part is used, then structural stability is improved, but flexibility during mounting is reduced

Engineering Contradiction:

Improvestructural stabilityVSAvoidmounting flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The linking part incorporates dynamic characteristics by allowing controlled movement or adjustment during mounting operations while maintaining structural stability during shipping and operation, adapting to different mounting conditions

Inventive Principle:

Principle #15Dynamics

AI summary

An electrical connector includes a pair of housing units side by side arranged with each other and equipped with the corresponding contacts, respectively. A pair of protection caps are assembled to the corresponding housing units horizontally in opposite directions, respectively. A linking part is mounted upon the pair of caps with a rigid suction region thereof in a symmetrical manner. The linking part is downwardly mounted upon the pair of caps with corresponding standoffs to space the main part of the linking part from the caps in the vertical direction so as not to block the related heat dissipation.
