Solution Overview

Problem

Electronic devices face challenges in maintaining functionality when exposed to water or foreign matter due to the lack of effective dustproof and waterproof protection, especially as they become more integrated and miniaturized.

Innovation Solution

A connection device with a housing that includes a connection hole and an opening to partially expose the connection hole on its surface, combined with a sealing member on the outer peripheral surface to prevent water and foreign matter infiltration, and a method for manufacturing this device to ensure miniaturization and effective sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a connection hole is formed in the housing to allow plug insertion, then connectivity function is enabled, but water and foreign matter can infiltrate into the electronic device

Engineering Contradiction:
Improveconnectivity functionVSAvoidwater and foreign matter infiltration
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The connection hole is segmented into two parts: a first hole portion extending from the first face and a second hole portion extending from the second face. This segmentation allows the connection function to be maintained while creating separate pathways that can be selectively sealed, preventing water and foreign matter infiltration through the connection structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A sealing member is introduced as an intermediary element that selectively covers the first hole portion or the second hole portion. This sealing member acts as a mediator between the connection requirement and the protection requirement, allowing the device to switch between connectivity mode and protection mode by positioning the sealing member appropriately.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Volume of moving object

If the electronic device is miniaturized to improve portability, then convenience is enhanced, but the complexity of implementing effective sealing structures increases

Engineering Contradiction:
Improvedevice sizeVSAvoidsealing structure complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The sealing member is merged with the housing structure, where it can be integrally formed with or attached to the housing. This merging reduces the number of separate components needed for sealing, simplifying the overall structure while maintaining effective protection against water and foreign matter in the miniaturized device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sealing member serves multiple functions: it seals the connection hole to prevent water and foreign matter infiltration, and it can be positioned to cover either the first hole portion or the second hole portion depending on operational requirements. This multi-functionality reduces the need for separate sealing structures for different scenarios, simplifying the overall design.

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

3Reliability

If a sealing member is added to prevent water infiltration, then protection is improved, but the device size and structural complexity increase

Engineering Contradiction:
Improvedustproof and waterproof protectionVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The sealing member is designed as a flexible component that can be made from elastic materials or thin sealing films. This allows the sealing function to be achieved with minimal additional volume, as the flexible nature of the sealing member enables it to conform to the connection hole structure without requiring bulky rigid sealing mechanisms.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

A connection device and method of manufacturing the same is provided. The connection device includes a housing including a first face, into which a plug is introduced, and a second face, that is formed to be in contact with the first face; a connection hole extending to the inside of the housing from the first face; an opening extending from the first face to the second face to partially expose the connection hole on at least the second face; and a sealing member arranged on an outer peripheral surface of the housing to surround a region where the opening is formed.
