Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Roll-off containers face corrosion issues due to water accumulation and damage from heavy loads, leading to reduced lifespan and unsightly appearance, with existing solutions being expensive and prone to damage.
Innovation Solution
A double-walled waste container design featuring a double-wall configuration with angled edge portions welded together, providing structural rigidity and a drainage system to prevent corrosion, along with a secure door mechanism for easy access and loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-corrosion coatings are applied to the roll-off container, then corrosion resistance is improved, but cost and time consumption increase
Solution Approach 1:
The patent removes the need for anti-corrosion coatings by extracting the harmful element (water/liquid accumulation) through drainage holes and weep holes built into the container structure itself, thereby avoiding the complexity and cost of applying protective coatings while maintaining corrosion resistance
Solution Approach 2:
The container performs its own corrosion protection function through integrated drainage features that automatically channel water away from the container walls, eliminating the need for external protective coatings and reducing maintenance requirements
2Reliability
If a lid is used to prevent water accumulation, then corrosion resistance is improved, but cost and time consumption increase
Solution Approach 1:
Instead of adding a lid to prevent water entry, the patent extracts the water that does enter through drainage holes and weep holes, providing a simpler and more cost-effective solution that maintains corrosion resistance without the complexity of a lid mechanism
3Strength
If the roll-off container is made of ferrous material, then structural strength is improved, but susceptibility to corrosion increases
Solution Approach 1:
The patent converts the harmful effect of water accumulation on ferrous materials into a beneficial drainage system that actively channels water away from the container walls through integrated drainage holes and weep holes, allowing the use of strong ferrous materials without compromising corrosion resistance
4Productivity
If large or heavy objects are loaded into the roll-off container, then waste handling capability is improved, but exterior surface damage increases
Solution Approach 1:
The patent segments the container wall structure into multiple components including reinforcement ribs and panels, distributing the impact forces from heavy loads across these segmented elements rather than concentrating stress on the exterior surface, thereby maintaining structural integrity and appearance while handling heavy waste
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The double-walled design enhances structural integrity, reduces corrosion, and maintains the container's appearance by distributing load stress to the inner wall, while the drainage system and secure door facilitate efficient waste handling and transportation.
Implementation Method 1
Each angled edge wall portion is welded to an adjacent angled edge wall portion and/or to the first wall

AI summary
The double-walled waste container provides an open-top roll-off container being rectangular in shape and having latching door portions at one end. The container employs a double wall construction to minimize damage, improve strength, and reduce weight. Additionally, the container provides a plurality of drain apertures which extend a full length of the container to drain off accumulated liquids and to prevent corrosion of the container.
