Integrated Toolbox Between Bulk Tank Hoppers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bulk tankers and trailers pose a risk of burn injuries to operators due to hot pipes during maintenance, and there is a need for a better way to access and store tools for these vehicles.
Innovation Solution
An integrated toolbox is incorporated into the design of bulk tank trailers, featuring a storage chamber between hoppers with a door for access and a lock for security, providing a dedicated space for tools while maintaining safety by separating the tool storage from the hot pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tools are stored in external locations on the trailer, then tool accessibility is improved, but operator safety deteriorates due to proximity to hot pipes
Solution Approach 1:
The patent combines the toolbox with the hopper structure by forming the storage box between the first and second hoppers, integrating tool storage into the existing trailer framework. This merging allows tools to be stored in a location that is structurally integrated rather than external, maintaining accessibility while removing the hazard of external proximity to hot pipes
Solution Approach 2:
The patent extracts the tool storage function from external locations and places it within the protected space between the hoppers. By taking out the toolbox from external mounting positions and integrating it into the hopper structure, the harmful thermal exposure is eliminated while preserving tool availability
2Object-affected harmful factors
If an integrated toolbox is formed between hoppers, then operator safety is improved by isolating tools from hot pipes, but device complexity increases
Solution Approach 1:
The space between the hoppers serves multiple functions: it structurally supports the tool storage box while also providing thermal isolation from hot pipes. The hopper structure itself becomes dual-purpose, both conveying bulk material and providing the framework for safe tool storage, thereby reducing overall system complexity despite the integration
Solution Approach 2:
The toolbox structure is merged with the hopper assembly, sharing common structural elements and mounting points. This integration eliminates the need for separate external toolboxes and their associated mounting hardware, reducing overall device complexity while achieving safety isolation
3Productivity
If the storage box is formed integral with hoppers, then manufacturing efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The storage box is formed as an integral part of the hopper assembly, likely as a single molded or fabricated component. This merging eliminates separate manufacturing and assembly steps for external toolboxes, improving manufacturing efficiency and productivity while the integral design inherently ensures proper alignment and fit
4Reliability
If a door with lock is added to the storage box, then tool security is improved, but ease of operation deteriorates due to additional access steps
Solution Approach 1:
The lock mechanism is integrated into the door assembly of the storage box, allowing the operator to secure tools during transit and quickly access them when needed. The self-contained locking system provides security without requiring external locking mechanisms, and the door design allows for quick engagement and disengagement, minimizing the operational impact of the security feature

AI summary
A trailer having an enclosed area with an integral toolbox is presented. The trailer includes a bulk tank with at least a first hopper and a second hopper. The first hopper has a first discharge port and the second hopper has a second discharge port. A discharge pipe is connected to the first and second discharge ports. A storage box is formed between and integral with the first hopper and the second hopper to define a storage chamber. A door is mounted on the storage box having open and close positions for respectively providing access to and blocking access to the storage chamber.
