Solution Overview

Problem

Dishwashers do not fully utilize the properties of all-in-one detergent tablets, as they have a static setup for salt, soap, rinse aid, and water hardness, making it impossible to select the best machine setup for these tablets, leading to suboptimal operation.

Innovation Solution

Incorporating a biodegradable radio frequency communication tag within the detergent tablets that provides data on the type and quantity of components, allowing the machine to optimize its operation based on the tag's information, and eliminating the need for a battery through energy harvesting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a static machine setup is used for detergent tablets, then the machine structure remains simple, but the machine cannot optimize operation based on different tablet compositions

Engineering Contradiction:
Improvemachine operation optimizationVSAvoidmachine setup complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The detergent tablet contains an embedded RFID tag that automatically provides composition information to the machine. The system self-configures by reading the tag data, eliminating the need for manual machine setup or complex user configuration interfaces.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The RFID tag embedded in the detergent tablet provides feedback information about the tablet's composition (soap, rinse aid, salt content) to the machine's reader. This feedback enables the machine to automatically adjust its operation parameters based on the actual detergent composition.

Inventive Principle:
Principle #23Feedback

2Loss of information

If an RFID tag is embedded in the detergent tablet, then data on component types and quantities can be provided, but the device complexity increases

Engineering Contradiction:
Improvedetergent composition informationVSAvoidconsumable product complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The RFID tag is integrated directly into the detergent tablet matrix, merging the communication function with the consumable product. This combination eliminates separate information carriers and reduces overall system complexity despite adding functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The RFID tag serves multiple functions: identifying the detergent type, indicating component quantities, and potentially tracking usage. This multi-functionality consolidates multiple information needs into a single component, reducing the need for separate systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If a biodegradable RFID tag is used, then environmental sustainability is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improveenvironmental impactVSAvoidtag production complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The RFID tag uses a biodegradable substrate (cellulose acetate) combined with conductive materials for the antenna and circuit elements. This composite structure maintains RFID functionality while enabling biodegradation, balancing environmental requirements with manufacturing feasibility.

Inventive Principle:
Principle #40Composite materials

4Use of energy by moving object

If energy harvesting is used to eliminate batteries, then the consumable product becomes fully biodegradable, but the device complexity increases

Engineering Contradiction:
Improveenergy independenceVSAvoidtag structure complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The RFID tag harvests energy from the electromagnetic field generated by the machine's reader during communication. This self-powering approach eliminates batteries and makes the entire consumable product biodegradable, as the energy harvesting circuit uses minimal non-biodegradable materials.

Inventive Principle:
Principle #25Self-service
