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 methods are limited, reducing overall counting operation efficiency, especially with large numbers of articles.

Innovation Solution

A counting scale that includes a weighing pan, a weighing sensor, a storage unit, an arithmetic processing unit, and a display unit, which automatically narrows down and displays candidate data by weighing identification, sorting by deviation, and optionally using external storage with hash tables for quicker data retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional methods (key input, barcode scanning) are used to call registered data, then data can be retrieved, but the counting operation efficiency deteriorates significantly when managing 50 or more articles

Engineering Contradiction:

Improvecounting operation efficiencyVSAvoidtime for calling registered data

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs automatic article identification by weighing the article on the pan and comparing its weight against registered data, eliminating the need for manual ID input or barcode scanning. The scale itself serves the identification function through automated weight-based matching.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual operations (key input, barcode scanning) with an automated weighing-based identification system. The mechanical weighing process is converted into an automatic data retrieval mechanism through weight comparison with registered articles.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If individual IDs of articles are managed manually, then each article can be identified, but the complexity of managing and inputting IDs increases

Engineering Contradiction:

Improveease of article identificationVSAvoidcomplexity of ID management system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the identification function from manual ID management and transforms it into an automated weight-based system. The complex ID management process is replaced by simply weighing the article and comparing its weight with registered data.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the identification parameter from manual ID input to automatic weight measurement. By using weight as the identification parameter, the system eliminates the need for complex ID management while maintaining accurate article identification.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If registered data for 50 or more articles is stored, then comprehensive article coverage is achieved, but the time required to call the correct data increases

Engineering Contradiction:

Improvenumber of articles that can be countedVSAvoidtime to retrieve data from large database

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent replaces manual data search through key input or barcode scanning with an automated weighing-based identification system. The scale automatically compares the measured weight against registered data for all 50+ articles, rapidly identifying the correct article without manual intervention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Inventive Principle:

Principle #25Self-service

AI summary

A counting scale includes a weighing pan, a weighing sensor connected to the weighing pan, a storage unit including a registered data table storing, as registered data, a unique identification number, an article name, and a unit weight with respect to one article, an arithmetic processing unit 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 configured to display the sorted candidate data.
