Solution Overview

Problem

Existing bulkhead connector installations require opening the housing for cable attachment, making the process complex and vulnerable to mechanical and electromagnetic interference, with limited protection against dirt and water ingress.

Innovation Solution

A bulkhead connector design with a recessed receptacle for mechanical and electromagnetic protection, accessible fixing means from outside the housing, and a sealing mechanism to prevent water ingress, allowing easy installation and maintenance without opening the housing, and accommodating various connector types for versatile applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the housing is opened for cable attachment to the bulkhead connector, then the installation can be performed, but the process becomes complex and vulnerable to mechanical and electromagnetic interference

Engineering Contradiction:
Improveease of installationVSAvoidinstallation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The bulkhead connector is divided into separate components: a housing that remains installed in the wall, and a connector portion that can be independently attached to the cable. This segmentation allows the connector to be installed on the cable before inserting it through the wall, eliminating the need to open the housing for attachment operations.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the housing is opened for cable attachment, then the connector can be attached, but mechanical and electromagnetic protection is compromised

Engineering Contradiction:
Improveaccessibility for installationVSAvoidmechanical and electromagnetic protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connector attachment function is extracted from the housing structure and placed on a separate cable-mounted component. This allows the housing to remain closed and sealed, maintaining its protective function, while the connector performs the attachment function externally through the wall opening.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A cable-mounted connector acts as an intermediary between the cable and the bulkhead connector in the wall. This intermediary allows attachment operations to be performed on the cable side without exposing the housing interior, thus maintaining protection while enabling installation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the entire cable is fed through the wall, then connection is achieved, but the installation process becomes complex and time-consuming

Engineering Contradiction:
Improveconnection stabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The connector is pre-attached to the cable before the cable is inserted through the wall. This preliminary action eliminates the need for complex in-situ attachment operations, significantly reducing installation time while maintaining connection stability through the pre-established connection.

Inventive Principle:
Principle #10Preliminary action

4Stability of the object's composition

If fixing means are not accessible from outside, then housing integrity is maintained, but installation and maintenance require opening the housing

Engineering Contradiction:
Improvehousing integrityVSAvoidease of maintenance
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The connector is designed to be self-contained on the cable side, allowing installation and maintenance operations to be performed on the cable without requiring access to the housing interior. The connector essentially services itself through the wall opening, maintaining housing integrity while enabling easy maintenance.

Inventive Principle:
Principle #25Self-service
