Solution Overview

Problem

Standard interfaces in devices are vulnerable to external environmental influences such as moisture, dust, and temperature fluctuations, which can compromise their functionality and reliability.

Innovation Solution

A sealing device comprising an outer sealing housing with a fastening element and a fastening device that securely engages with the interface, providing a tight seal against environmental influences, and featuring sealing means like O-rings or sealing gels to prevent the ingress of dust and liquid, while also protecting against mechanical and electromagnetic interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a standard interface is opened in a wall or housing for connectivity, then connection capability is improved, but vulnerability to environmental influences (moisture, dust) increases

Engineering Contradiction:
Improveconnection capabilityVSAvoidvulnerability to environmental influences
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The sealing device is divided into multiple functional segments: a sealing housing that mounts to the wall, a connector housing that receives the connector, and a sealing element that creates the barrier. This segmentation allows the connection function to be separated from the sealing function, enabling both to be optimized independently while working together as a integrated solution.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing device acts as an intermediary component between the wall opening and the connector. It mediates the conflict by providing a transition zone that maintains the protective environment of the wall while accommodating the connection function, thus eliminating direct exposure of the interface to environmental factors.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If the sealing device is designed to maintain tight seal in both plugless and plugged-in states, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesealing consistencyVSAvoidsealing mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing element is designed to be dynamically adaptable to different states. It can deform or shift position to maintain effective sealing whether the connector is absent or present. This dynamic behavior eliminates the need for separate sealing mechanisms for different states, reducing overall complexity while maintaining reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sealing element's physical parameters (such as its cross-sectional shape, material properties, or position) change in response to the presence or absence of a connector. These parameter changes allow the same sealing structure to effectively seal in both plugless and plugged-in states without requiring complex additional components.

Inventive Principle:
Principle #35Parameter changes
