Solution Overview

Problem

Household appliances from different manufacturers cannot communicate with each other due to the lack of a common protocol, and customizing network cards for each product is inefficient in terms of inventory management, cost, and labor.

Innovation Solution

A standardized network card with a memory unit containing ID information and communication protocols is provided, which can be installed by the user, allowing communication with a control card that enables serial communication and software module configuration, enabling communication between appliances of different brands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If network cards are customized for each household appliance product, then communication compatibility between different appliances is improved, but inventory management complexity increases and production efficiency decreases

Engineering Contradiction:
Improvecommunication compatibilityVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The network card is divided into two independent parts: a standardized hardware platform that remains unchanged across products, and a separate memory unit that contains product-specific configuration data, protocols, and software modules. This segmentation allows the main network card to be mass-produced efficiently while individualization is achieved through the removable memory unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The memory unit is prepared in advance with all necessary configuration data, protocols, and software modules specific to each appliance type. This preliminary preparation allows the standardized network card to be produced once and reused across multiple products, eliminating the need for customizing the entire network card for each appliance.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If network cards are customized for each household appliance product, then communication compatibility between different appliances is improved, but inventory management complexity increases

Engineering Contradiction:
Improvecommunication compatibilityVSAvoidinventory management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is segmented into a standardized network card (identical across all products) and a product-specific memory unit. This reduces inventory complexity by allowing the main network card to be stocked in large quantities as a universal component, while only the smaller memory units need to be managed per product variant.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized network card is designed to be universally compatible with multiple household appliance products through a common interface and architecture. This universality allows the same network card hardware to serve multiple product lines, significantly reducing inventory management complexity while maintaining communication compatibility.

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

3Adaptability or versatility

If network cards are customized for each household appliance product, then communication protocols are optimized for each product, but production cost increases

Engineering Contradiction:
Improveprotocol optimizationVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The network card functionality is segmented into a standardized hardware platform that can be mass-produced at low cost, and a separate memory unit containing product-specific protocols. This allows the expensive customization to be limited only to the small memory unit rather than the entire network card, reducing overall production costs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized network card serves as a master template that can be copied and deployed across multiple appliance products without modification. Only the memory unit needs to be customized for each product, allowing the majority of the network card to be produced through efficient copying and mass-production techniques.

Inventive Principle:
Principle #26Copying
