Grain Storage Lid Assembly with Slanted Roof Rail Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Grain storage containers face challenges in designing a lid assembly that efficiently opens and closes while maintaining structural integrity and ease of use, particularly with slanted roofs and the need for aeration systems to prevent spoilage.
Innovation Solution
A lid assembly featuring a rail guide member mounted to a slanted roof, a rotatable and slidably coupled lid, an attachment bracket, and a cable system that allows the lid to move between open and closed positions while maintaining alignment with the roof's pitch, utilizing a furring channel and pivotal connections for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a lid assembly is designed to slide along a rail guide member on a slanted roof, then the lid can maintain alignment with the roof pitch for structural compatibility, but the mechanism becomes more complex requiring rotatable and slidable couplings
Solution Approach 1:
The lid assembly incorporates a coupling member that can both rotate and slide along the rail guide member, allowing the system to dynamically adapt to the slanted roof geometry while maintaining alignment. This dynamic coupling mechanism enables the lid to move between open and closed positions while accommodating the angular relationship between the horizontal lid movement and the slanted roof surface.
2Ease of operation
If the lid is made rotatably coupled to the rail guide member, then smooth operation between open and closed positions is achieved, but the structural integrity requirements increase
Solution Approach 1:
The coupling member acts as an intermediary between the lid and the rail guide member, facilitating smooth rotational and sliding motion while distributing mechanical loads. This intermediary component enables ease of operation through controlled movement while the overall assembly design, including the rail guide member and mounting structure, ensures structural integrity is maintained throughout the mechanism.

AI summary
A storage container system includes a storage container having a frustoconical roof defining a central opening and a lid assembly mounted to the roof of the storage container. The lid assembly includes a rail guide member mounted to the roof of the storage container and oriented such that a center longitudinal axis of the rail guide member has a same pitch as the roof and a lid rotatably coupled to the rail guide member and configured to slide along the rail guide member between open and closed positions over the opening, where when the lid is in an open position, an upper surface of the lid has a same pitch as the roof.
