Solution Overview

Problem

Existing database systems for detergents and water hardness are prone to becoming outdated, especially with new product launches and varying regional water conditions, leading to inaccurate dosing and operational inefficiencies in automatic dosing devices.

Innovation Solution

A method that utilizes sensors to detect detergent product identification, transmits information requests to databases, and leverages crowdsourcing services to systematically update and complete database information, ensuring precision in detergent dosing and water hardness adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional database systems are used to store detergent information, then the system has a structured storage framework, but the database quickly becomes outdated when new products are marketed

Engineering Contradiction:
Improvedata accuracyVSAvoiddatabase update delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system implements feedback loops where usage data from automatic dosing devices is continuously collected and fed back to trigger database updates. When a detergent product is detected via sensors, the system checks the database for information, and if the product is new or information is missing, it initiates a crowdsourcing request to gather dosage instructions, thereby continuously updating the database with current product data.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system enables self-service by allowing the database to automatically request and acquire new detergent information through crowdsourcing services without manual intervention. The automated dosing devices themselves contribute to database completion by providing usage data that triggers information gathering for new products.

Inventive Principle:
Principle #25Self-service

2Loss of information

If OCR scan methods are used to read dosage instructions, then direct product information can be extracted, but the method is technically complex and fails with damaged or soiled packages

Engineering Contradiction:
Improvedosage instruction retrievalVSAvoidOCR system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system introduces an intermediary approach by using sensor-based product identification (such as barcode scanning or RFID) followed by database lookup and crowdsourcing verification, rather than directly OCR-ing the packaging. This intermediary database layer simplifies the system by separating product identification from information extraction, making it more robust to packaging conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical/visual OCR system with an electronic sensor-based identification system combined with digital database retrieval. Instead of using optical character recognition that requires clear visual access to text, the system uses sensors to detect product identifiers and electronically retrieves information, substituting a fragile visual system with a more robust electronic one.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If databases are manually updated, then data quality can be controlled, but the process is time-consuming and cannot keep pace with new product launches

Engineering Contradiction:
Improvedata qualityVSAvoiddatabase update speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system enables self-service by allowing the database to automatically request and acquire new detergent information through crowdsourcing services without manual intervention. The automated dosing devices themselves contribute to database completion by providing usage data that triggers information gathering for new products.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback loops where usage data from automatic dosing devices is continuously collected and fed back to trigger database updates. When a detergent product is detected via sensors, the system checks the database for information, and if the product is new or information is missing, it initiates a crowdsourcing request to gather dosage instructions, thereby continuously updating the database with current product data.

Inventive Principle:
Principle #23Feedback

4Stability of the object's composition

If regional water hardness variations are not updated, then the system maintains stability, but dosing accuracy deteriorates in areas with changed water conditions

Engineering Contradiction:
Improvesystem stabilityVSAvoiddosing accuracy
Core Design Contradiction:
Stability of the object's compositionVSMeasurement precision

Solution Approach 1:

The system transitions from static water hardness values to dynamic, location-specific data that can be updated as conditions change. By using GPS coordinates and postal codes to identify service areas and linking them to water hardness information from crowdsourcing, the system adapts to regional variations and updates automatically when new water hardness data is collected.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system applies local quality by maintaining different water hardness values for different geographical locations rather than using a single global value. Each location receives customized water hardness data based on its specific regional conditions, allowing the dosing system to be optimized for local water characteristics while maintaining overall system stability.

Inventive Principle:
Principle #3Local quality
