Solution Overview
Problem
Managing multiple chemicals in laboratories or hospital dispensaries is challenging due to the difficulty in tracking the remaining weight and usage patterns in real-time, especially when chemicals are scattered across different locations and users, leading to inefficient inventory management and potential safety concerns.
Innovation Solution
A remote management system using a master smart scale with a micro server and slave smart scales connected via radio frequency tags, allowing for real-time tracking and recording of chemical usage through a master-slave mode and remote communication, enabling managers to monitor usage states from any location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual recording and calculation of chemical usage is performed, then data accuracy can be ensured, but time consumption increases significantly and real-time monitoring becomes impossible
Solution Approach 1:
The patent replaces the manual mechanical recording system with an automated electronic weighing system. The smart scale automatically records chemical weights, calculates usage amounts, and transmits data to a server, eliminating manual recording while maintaining data accuracy through automated measurement and calculation processes.
Solution Approach 2:
The system enables self-service automation where the weighing device automatically performs measurement, calculation, and data transmission without human intervention. The scale autonomously records initial and remaining weights, computes usage amounts, and sends data to the server, freeing users from time-consuming manual tasks.
2Ease of operation
If all chemicals are stored in one location for easy management, then accessibility is improved, but the system cannot handle chemicals scattered across multiple laboratories
Solution Approach 1:
The patent creates a universal management system that can handle chemicals across multiple locations. The server receives and consolidates data from smart scales in different laboratories, providing a unified view of all chemical inventories regardless of physical location, thus achieving multi-location capability while maintaining ease of access through centralized digital management.
Solution Approach 2:
The system transitions from physical centralized storage to digital centralized management. By moving the management dimension from physical space to virtual space, the system can access and monitor chemicals scattered across multiple laboratories through network connectivity, effectively adding a digital dimension to overcome physical dispersion.
3Reliability
If a centralized server is used to store all chemical data, then data security is improved, but network vulnerabilities increase
Solution Approach 1:
The patent segments the data storage and processing functions. The server stores only essential chemical information and usage data, while the smart scale performs local weighing and initial data processing. This segmentation reduces the attack surface on the server and distributes security responsibilities across multiple devices.
Solution Approach 2:
The smart scale acts as an intermediary device between the physical chemical and the server. It performs local validation, calculates usage amounts, and transmits processed data to the server, reducing direct exposure of the server to potential network threats and adding a security layer through the intermediary device.

Data Source
AI summary
A method is performed by using a master smart scale with a master-slave mode, a remote communication device and a slave smart scale to manage multiple chemicals from a remote place. The master smart scale performs an initialization procedure to obtain an initial weight of one chemical; generate an identification information by reading a radio frequency tag of the chemical; use the identification information to inform the remote communication device to open an input page for users to input a basic information into the master smart scale; and mark the basic information and the initial weight with the identification information. In the master-slave mode, the master smart scale allows receiving the information of the chemical from its slave smart scale. For inquiry, a specific page is opened with the remote communication device to receive and display a statistical data generated from the master smart scale.
