Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional replenishment trolleys require manual movement by workers, leading to inefficient product replenishment operations.
Innovation Solution
A replenishment assistance robot equipped with an RFID reader, mobile body, and terminal that moves to product locations based on instructions, allowing workers to focus on inventory operations and ensuring efficient product replenishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional replenishment trolleys are used, then workers can perform replenishment operations, but the trolleys require manual movement which reduces work efficiency
Solution Approach 1:
The replenishment assistance robot autonomously navigates to product locations and positions itself for replenishment operations without requiring manual movement by workers. The robot independently performs the transportation function, allowing workers to focus solely on the replenishment task.
Solution Approach 2:
The patent replaces the manual mechanical pushing/pulling of trolleys with an automated mobile body that uses sensors, processors, and propulsion mechanisms to autonomously transport itself to the required locations.
2Productivity
If workers manually move replenishment trolleys to product locations, then replenishment can be performed, but time is lost in movement operations
Solution Approach 1:
The robot pre-navigates to the product location and positions itself ready for replenishment before the worker arrives. This preliminary positioning action eliminates the time workers would otherwise spend moving the trolley to the correct location.
Solution Approach 2:
The robot independently handles the transportation and positioning tasks without requiring worker intervention for movement, thereby eliminating the time loss associated with manual trolley movement.
3Extent of automation
If RFID readers are integrated into the mobile body, then automated product identification is achieved, but device complexity increases
Solution Approach 1:
The mobile body is designed as a multi-functional platform that combines navigation, RFID reading, and communication capabilities in a single integrated system. This universal design consolidates multiple functions into one device, managing complexity through functional integration.
Solution Approach 2:
The RFID reader acts as an intermediary component that automatically identifies products and communicates their information to the system, enabling automated product recognition without requiring complex manual identification processes.

AI summary
It is possible to provide a replenishment assistance robot and a replenishment assisting system capable of assisting a worker in efficiently replenishing a product. A replenishment assistance robot includes a housing for housing a product, an RFID reader including an antenna capable of reading RFID tags attached to the product on a shelf and capable of reading an RFID tag of the product when the product is housed in the housing, a terminal configured to receive a replenishment instruction of a product on the shelf, and a mobile body containing the housing and the RFID reader and configured to move to a location where a stock of the product is arranged based on location information of the product included in the replenishment instruction.
