Construction Material Transport Container with Side Doors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The residential roofing industry faces inefficiencies in material transport, requiring three separate round-trips for delivering new shingles and removing old shingles due to the need for multiple vehicle trips and space constraints on flatbed trucks.
Innovation Solution
A construction material transport container with four side doors and transversely disposed forklift pockets allows for loading and unloading of materials from both sides, reducing trips by enabling a single round-trip delivery and utilizing a container that can be easily handled and stacked, with features for use with roll-off or hook lift vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a container is delivered and left by a roll-off or hook lift vehicle, then the container can be loaded with old shingles, but three separate round-trips are required to deliver new materials and pick up used materials
Solution Approach 1:
The patent combines the delivery of new materials and the removal of old materials into a single integrated container system. The container can receive new shingles from a flatbed truck and simultaneously or subsequently load old shingles for removal, merging two separate transport operations into one unified system that reduces the number of required trips from three to two.
Solution Approach 2:
The container is designed with multi-functionality to serve multiple purposes: it can be loaded onto flatbed trucks for new material delivery, loaded onto roll-off or hook lift vehicles for waste removal, and features dual-side access for both material types. This universal design allows the same container to handle both new material transport and old material removal operations.
2Loss of time
If new materials are loaded onto a container placed on a truck, then both the container and new materials can be delivered by a single round-trip, but space on the bed of the truck is required
Solution Approach 1:
The container features dynamic door mechanisms that can swing open towards the interior of the container, allowing forklift operators to safely see through the container without obstruction when handling the container. This dynamic configuration enables efficient loading and unloading operations while maintaining a compact form factor for transport.
3Ease of operation
If four side doors are used to form substantially all of two side walls, then loading and unloading from both sides is enabled, but the container structure becomes more complex
Solution Approach 1:
The container is segmented into multiple access points with four side doors that can be independently opened or closed. This segmentation allows selective access to different portions of the container interior, enabling efficient loading and unloading operations from both sides while maintaining structural organization through the modular door assembly design.

AI summary
A construction material transport container includes four side doors that form substantially all of two side walls of the container. The container includes transversely disposed forklift pockets that can be used to load the container onto a flatbed truck. With the container on a truck and the side doors open, new construction materials can be loaded onto the container from both sides. Both the container and the new materials can be delivered to a job side by a single delivery using a truck-attached forklift. The empty container can then be used as a receptacle for recyclable materials. The container further includes roll-off or hook lift vehicle tracks configured so that the container can be picked up and hauled to a recycling or refuse center. A rear door of the container can be opened so that the container can be tilted by the vehicle to offload the used material.
