Slide Lock Assembly for Sealed Outdoor Telecom Enclosures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor telecommunications equipment enclosures face challenges in resisting harsh outdoor conditions and protecting internal components from debris and environmental factors due to inadequate sealing and locking mechanisms.
Innovation Solution
The implementation of a slide lock assembly with a housing and slider, featuring protrusions, gaskets, and rotators, which provides secure coupling between the dome and base while inhibiting debris ingress and allowing for easy user operation, ensuring reliable protection and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locking mechanisms are used in outdoor telecommunications enclosures, then the enclosure can be assembled and disassembled, but the sealing against debris and environmental factors is inadequate
Solution Approach 1:
The patent replaces traditional multi-component mechanical locking mechanisms with a slide lock assembly that uses a simple linear sliding motion. The slider moves within a channel to engage or disengage the dome from the base, eliminating complex bolts, screws, or multi-step locking procedures while maintaining secure attachment and effective sealing against environmental factors.
Solution Approach 2:
The patent incorporates a gasket within the slide lock assembly that flexes to maintain sealing between the dome and base. This flexible sealing element deforms to accommodate the sliding motion while continuously blocking debris and environmental factors from entering the enclosure, ensuring reliable protection throughout the locking and unlocking cycles.
2Object-affected harmful factors
If secure coupling mechanisms are implemented to protect against harsh outdoor conditions, then the enclosure becomes more resistant to environmental factors, but the complexity of the locking mechanism increases
Solution Approach 1:
The patent combines the sealing function and locking function into a single integrated slide lock assembly. The slider simultaneously performs the sealing action by compressing the gasket and the locking action by engaging the dome with the base, eliminating the need for separate sealing elements and locking mechanisms. This merger reduces overall device complexity while maintaining protection against debris and environmental factors.
Solution Approach 2:
The slide lock assembly serves multiple functions simultaneously: it provides mechanical coupling between the dome and base, creates a sealed barrier against environmental factors, and enables easy operation through a single sliding motion. This multi-functionality eliminates the need for multiple separate components, reducing overall system complexity while achieving comprehensive protection.
3Reliability
If a sealed enclosure is used to prevent debris ingress, then the internal components are protected, but the accessibility for user operation is reduced
Solution Approach 1:
The patent employs a dynamic sealing system where the gasket flexes and deforms during the sliding operation. When the slider moves to the unlocked position, the gasket relaxes to allow easy removal of the dome. When the slider moves to the locked position, the gasket compresses to create a tight seal. This dynamic behavior maintains both accessibility during operation and protection during the sealed state.

AI summary
An outdoor telecommunications equipment enclosure includes a dome, a base for receiving the dome, and a slide lock assembly for coupling the dome to the base. The slide lock assembly includes a housing coupled to one of the dome and the base and defining a channel and a slider positioned within the channel. The slider is moveable between a retracted position and an extended position for engaging the other one of the dome and the base. In one example embodiment, one of the slider and the housing includes multiple protrusions in contact with the other one of the slider and the housing. The protrusions inhibit surface contact between the slider and the housing. In another example embodiment, the slide lock assembly includes a gasket, seal and/or plug to inhibit ingress of debris into the slide lock assembly. In yet another example embodiment, the slide lock assembly includes a rotator having an actuator head accessible to a user such that when the rotator is rotated in a first direction via the actuator head, the rotator moves the slider into the extended position.
