Rotational Drum Package Testing for Warehouse Loading Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods of testing packages require actual conveyance through a warehouse, which is inefficient and imposes operational challenges on warehouse management and package design.
Innovation Solution
A rotational test apparatus comprising a rotatable drum with obstacles and sensors to simulate the loading profiles experienced by packages in a warehouse, allowing lab-based testing that replicates real-life conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If packages are conveyed through a warehouse for testing, then the loading profile can be accurately measured, but it imposes operational inefficiency and challenges on warehouse management
Solution Approach 1:
The patent creates a simplified copy of warehouse conditions using a rotatable drum with obstacles that replicate the loading profiles experienced during actual warehouse conveyance. Sensors on the drum capture simulated loading data that mirrors real warehouse conditions without requiring actual warehouse operations, thus resolving the contradiction between accurate measurement and operational efficiency.
2Reliability
If packages are conveyed through a warehouse for testing, then real loading conditions can be observed, but it increases testing time and resource consumption
Solution Approach 1:
The patent pre-configures a drum with obstacles and sensors before testing begins. The drum is rotatable and pre-equipped with measurement devices, allowing loading profiles to be captured immediately upon rotation without requiring actual warehouse conveyance. This preliminary preparation enables rapid, reliable testing that maintains accuracy while dramatically reducing testing time.
3Productivity
If a rotational test apparatus is used, then testing can be done in a lab setting, but the device complexity increases
Solution Approach 1:
The patent divides the testing function into separate modular components: a rotatable drum, obstacle elements, sensor assemblies, and a support structure. Each component can be independently configured and adjusted. The drum can be rotated to different positions, and obstacles can be selectively placed, allowing the complex testing function to be achieved through simple, modular segments rather than a monolithic complex system.

AI summary
A rotational test apparatus includes a support assembly, a plurality of bolts, an obstacle, and a drum. The drum is rotatably supported by the support assembly and includes a first end wall, a second end wall, and a side wall which cooperate to define an interior compartment. The first end wall defines a passageway which extends into the interior compartment and is sized to facilitate selective insertion and removal of packages therethrough. The side wall defines a plurality of threaded apertures including a first plurality which is occupied by said bolts and a second plurality which is unoccupied. The second plurality exceeds the first plurality by at least a ratio of 10 to 1. The obstacle is secured to the side wall within the interior compartment by at least some of said bolts threaded into respective ones of the first plurality of the threaded apertures. Methods are also provided.
