Rolling Coiling Service Door Enclosure for Exterior Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of exterior enclosures that can withstand snow loads, completely enclose a space from above and front when closed, and open from above and front when needed, while also preventing access by wildlife and ensuring hands-free entry for sanitation personnel without using expensive metal containers.
Innovation Solution
An enclosure system with a rear wall, central posts, side walls, and a rolling coiling service door that can be electronically controlled to open and close, featuring tracks for the door to roll along and internal structural supports for strength, allowing for secure and accessible storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standard trash container is used in exterior environments, then cost is reduced, but protection from snow loads and wildlife access is insufficient
Solution Approach 1:
The enclosure system is divided into separate functional components: a standard container unit and a protective enclosure structure. This allows the use of inexpensive standard containers while adding protection through the separate enclosure that can withstand snow loads and prevent wildlife access.
Solution Approach 2:
The enclosure combines materials suitable for different functions: the standard container provides basic storage, while the added enclosure structure with tracks and rolling doors provides environmental protection. This composite approach achieves both cost-effectiveness and reliability.
2Reliability
If expensive metal containers are used, then protection from wildlife and snow loads is improved, but accessibility and hands-free entry are lost
Solution Approach 1:
The manual door operation is replaced with an automated rolling door system controlled by electronic controls. The rolling door mechanism, guided by tracks, can be opened and closed without manual intervention, enabling hands-free entry while maintaining protection.
Solution Approach 2:
The rolling door system is designed to operate automatically through electronic controls, allowing the enclosure to service itself by opening and closing without human intervention. This maintains security while providing easy access when needed.
3Reliability
If the enclosure is completely closed, then protection from unauthorized access is maximized, but accessibility for sanitation personnel is reduced
Solution Approach 1:
The enclosure transitions from a static closed state to a dynamic state with the rolling door that can be opened and closed. This dynamic capability allows the enclosure to maintain security when closed while providing easy access for sanitation personnel when opened, resolving the contradiction between protection and accessibility.

AI summary
An enclosure system is adapted for exterior storage. The storage system has a rear wall, joined to two side walls with a mechanical housing there between. A first track is arranged on a first inner edge of the first side wall and extends distally away from the mechanical housing while parallel to the ground surface and then downward toward the ground surface. A second track is arranged on a second inner edge on the second side wall and extends distally away from the mechanical housing while parallel to the ground surface and then downward toward the ground surface. A rolling coiling service door is housed in the mechanical housing, and is configured to roll down the first track and the second track to enclose an internal space between the first side wall and the second side wall.
