Multi-Directional Hinge for Waterproof Enclosure Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water-proof enclosures for electrical protection elements fail to balance the need for environmental protection with ease of access, often exposing the elements to damage or making it difficult for technicians to access them, especially in underwater or humid environments.
Innovation Solution
The enclosure design includes a hinge system with adjustable door movement in multiple directions, featuring slotted and threaded holes for secure fastening elements, allowing for rotation and horizontal movement to ensure a gas and liquid-tight seal without exposing hardware to corrosion, and incorporating gaskets and wedge projections for effective sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the enclosure is made waterproof to protect electrical components, then protection from environmental damage is improved, but access for maintenance becomes more difficult
Solution Approach 1:
The enclosure is divided into a stationary housing and a movable door that can be opened independently. The hinge system allows the door to be segmented from the main housing, enabling access to electrical components without compromising the overall waterproof integrity of the enclosure when closed.
Solution Approach 2:
The hinge system incorporates dynamic adjustment capabilities with slotted holes and threaded fasteners that allow the door position to be adjusted in multiple directions. This dynamic positioning enables the door to maintain proper sealing contact while allowing easy opening and closing for maintenance access.
2Stability of the object's composition
If the hinge is designed for secure fastening, then structural stability is improved, but adjustability for proper sealing is reduced
Solution Approach 1:
The hinge fastening system uses slotted holes combined with threaded fasteners, creating a dynamic fastening mechanism. The slots allow positional adjustment while the threaded fasteners provide secure locking, enabling both structural stability and adaptability for proper sealing contact between the door and housing.
Solution Approach 2:
The hinge design allows changing of geometric parameters through the slotted hole configuration, enabling adjustment of the door position in multiple directions. This parameter adjustment capability ensures proper sealing contact while maintaining secure fastening through the threaded fastener system.
3Reliability
If the door is pulled into the housing for sealing, then gas and liquid tight seal is improved, but hardware exposure to crevice corrosion increases
Solution Approach 1:
Instead of pulling the door edge into the housing crevice (which exposes hardware to corrosion), the hinge system is designed to pull the door face into the housing. This inverts the sealing mechanism, allowing the gasket to compress against the door face while keeping hardware away from crevice areas where water could accumulate and cause corrosion.

AI summary
The disclosure generally relates to an exemplary hinge of an enclosure that can house an electrical network protection element and provide protection to the electrical network protection element against damage in various environments such as when the enclosure is placed in an underground vault that may be flooded during rain, or when a liquid (e.g., oil) comes into contact with the enclosure. The hinge may include two portions, one portion attached to one or more doors of the enclosure and one portion attached to a housing of the enclosure. The hinge may be configured such that it may be adjusted in multiple directions (for example, beyond one plane of rotation that typical hinges may offer), and thus allow for greater adjustability of the one or more doors of the enclosure relative to the housing of the enclosure.
