Solution Overview

Problem

The existing connector design allows for gaps between the contact point and the protector, and between the protector and the base body, which can lead to liquid intrusion, such as water, from the outside.

Innovation Solution

Incorporating first and second waterproof elastic members between the contact and the protector, and between the protector and the base body, respectively, with intersecting pushing portions and a resin member to cover the contact, preventing liquid intrusion by ensuring continuous contact and sealing around the connector's openings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the contact point protrudes from the opening portion of the protector and is movable with respect to the protector, then the contact can be electrically connected to the external device by pushing the connection terminal, but there is a gap between the contact point and the opening portion of the protector which allows liquid intrusion

Engineering Contradiction:
Improveelectrical connection capabilityVSAvoidliquid intrusion
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs waterproof elastic members (flexible sealing elements) positioned between the contact and the first opening portion of the protector, and between the protector and the second opening portion of the base body. These flexible sealing members deform to accommodate the movable contact while maintaining continuous contact to prevent liquid intrusion, thus resolving the contradiction between operational mobility and liquid protection.

Inventive Principle:
Principle #30Flexible shells and thin films

2Object-affected harmful factors

If waterproof sealing members are added between the contact and protector, and between the protector and base body, then liquid intrusion is prevented, but the device complexity increases

Engineering Contradiction:
Improveliquid intrusion preventionVSAvoidnumber of components
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent integrates the waterproof elastic members into the existing connector structure, where the first waterproof elastic member is positioned between the contact and the first opening portion of the protector, and the second waterproof elastic member is positioned between the protector and the second opening portion of the base body. This integration approach adds sealing functionality while minimizing structural complexity by utilizing the existing spatial relationships between components.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A connector includes: a contact including a contact portion connected to a connection terminal by pushing the connection terminal of an external device; a protector protecting the contact portion by covering the contact and including a first opening portion making the contact portion protrude; and a base body accommodating the contact and the protector, and including a second opening portion making the protector protrude; a first waterproof elastic member provided between the contact and the first opening portion and preventing liquid from intruding from a space between the contact and the first opening portion; a second waterproof elastic member provided between the protector and the second opening portion and preventing liquid from intruding from a space between the protector and the second opening portion. The contact portion is movable with respect to the first opening portion. The protector is movable with respect to the second opening portion.
