Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In fulfillment centers, dense arrangements of container pods cause radio interference, reducing wireless communication performance and creating bottlenecks in the logistics operations, especially for mobile robots transporting containers.
Innovation Solution
Implementing floor-based antennas that radiate from the floor surface instead of the ceiling to improve wireless communication range and reduce interference, enhancing connectivity and data transmission speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If container pods are arranged densely to increase storage capacity, then storage efficiency is improved, but radio interference increases and wireless communication performance deteriorates
Solution Approach 1:
The patent transitions wireless access points from ceiling-mounted (vertical dimension) to floor-based (horizontal dimension) deployment. This dimensional change allows RF signals to propagate upward through gaps between container pods, avoiding the blocking effect of dense overhead arrangements and eliminating the trade-off between storage density and wireless communication quality.
2Ease of manufacture
If ceiling-mounted antennas are used for wireless communication, then installation is simplified, but communication range is limited and error rates increase in dense environments
Solution Approach 1:
The patent inverts the conventional ceiling-mounted antenna arrangement by placing floor-based antennas at ground level. This inversion allows RF signals to propagate upward through available space between container pods, achieving both improved communication reliability and extended range while maintaining operational simplicity through standardized floor box installations.
3Reliability
If floor-based antennas are deployed to improve wireless communication, then communication range increases and error rates decrease, but device complexity increases
Solution Approach 1:
The floor box serves multiple functions: it provides structural support for the antenna, offers electrical connectivity through integrated conduits, enables cable management, and maintains floor surface integrity. This multi-functionality consolidates what would otherwise be separate components into a single standardized unit, reducing overall system complexity despite the architectural change.
