Counting Scale Article Retrieval by Unit Weight Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for calling registered data in a counting scale are inefficient, particularly when managing individual IDs, key input of article names is time-consuming, and barcode-based methods are limited, especially for large numbers of articles.
Innovation Solution
A counting scale with a weighing pan, weighing sensor, storage unit, and arithmetic processing unit that narrows down and displays candidate data by weighing identification, using a hash table for faster data retrieval, and sorting by deviation, chronological order, and frequency to improve data calling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional methods (key input of ID or article name) are used to call registered data, then the counting operation can be performed, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The system automatically identifies the target article by weighing it and autonomously retrieves the corresponding registered data without requiring manual ID input or article name entry. The arithmetic processing unit performs the data retrieval operation automatically based on the measured weight, making the system self-serving and eliminating manual intervention.
Solution Approach 2:
The patent replaces manual mechanical operations (key input, barcode scanning) with an automated weighing-based identification system. The weighing sensor measures the article weight, and the arithmetic processing unit uses this measurement to automatically retrieve registered data, substituting manual input mechanisms with an automated measurement-and-retrieval system.
2Adaptability or versatility
If registered data for 50 or more articles are stored, then the system can handle diverse articles, but calling each registered data reduces counting operation efficiency
Solution Approach 1:
The patent replaces manual search and selection processes with an automated weighing-based identification system. The weighing sensor measures the article weight, and the arithmetic processing unit automatically retrieves the corresponding registered data from the storage unit, eliminating the need for manual searching through large datasets and maintaining high efficiency even with 50 or more registered articles.
Solution Approach 2:
The system uses weight as a unique parameter to identify articles instead of requiring manual input of IDs or names. By changing the identification parameter from manual input fields to physical weight measurement, the system can efficiently retrieve data for any number of registered articles without reducing operational speed.
3Ease of operation
If barcode scanning is used to call registered data, then the operation is simplified, but the method cannot be used when the target article has no barcode
Solution Approach 1:
The weighing-based identification system serves as a universal method that can identify any article regardless of whether it has a barcode, individual ID, or article name. The system measures the physical weight property common to all articles and uses this to retrieve registered data, making it applicable to all types of articles without requiring specific identifiers or barcodes.
Solution Approach 2:
The patent replaces barcode scanning technology with a weighing-based identification system. Instead of using optical scanning that requires barcodes, the system uses a weighing sensor to measure the article's weight and automatically retrieves registered data based on this measurement, eliminating the limitation of barcode requirement while maintaining ease of operation.

AI summary
The efficiency of calling of registered data in a counting scale is improved. In order to achieve the object, a counting scale (10) includes a weighing pan (11) on which a target article desired to be counted is placed, a weighing sensor (21) connected to the weighing pan, a storage unit (24) including a registered data table (25) storing, as registered data, at least a unique identification number, an article name, and a unit weight with respect to one article, an arithmetic processing unit (23) configured to urge placement of one piece of the target article on the weighing pan, calculate a unit weighed value of the one piece of the target article from the weighing sensor, narrow down registered data including a unit weight within a predetermined range with respect to the unit weighed value as candidate data from the registered data table, and obtain sorted candidate data by selecting and sorting the candidate data in ascending order of absolute value of deviation from the unit weighed value, and a display unit (51) configured to call and display the sorted candidate data in descending order of search ranking.
