Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional electric home appliances are replaced with new appliances having IoT functions, then IoT functionality is achieved, but user burden and cost increase significantly

Engineering Contradiction:
ImproveIoT functionalityVSAvoiduser burden
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The invention divides the IoT functionality into a separate accessory module that can be attached to existing appliances rather than integrating it into the appliance itself. This segmentation allows users to add IoT capabilities without replacing entire appliances, reducing burden and cost while achieving the desired functionality.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If accessories are designed to be easily detachable, then repositioning flexibility is improved, but the risk of loss increases

Engineering Contradiction:
Improverepositioning flexibilityVSAvoidrisk of loss
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The attachment mechanism uses asymmetric design with direction-setting protrusions and recesses that allow easy attachment in the correct orientation but prevent accidental detachment. The asymmetric geometry provides natural alignment guides that reduce the risk of loss while maintaining repositioning flexibility when intentionally removed.

Inventive Principle:
Principle #4Asymmetry

3Ease of operation

If push-type buttons use elastic members for restoring force, then switch return function is achieved, but manufacturing precision and restoring force control become difficult

Engineering Contradiction:
Improveswitch return functionVSAvoidrestoring force control
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The invention replaces traditional elastic members (springs) with a mechanical cam mechanism that provides restoring force through geometric shape rather than material elasticity. This substitution eliminates the need for precise control of elastic properties and simplifies manufacturing while maintaining reliable switch return function.

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

AI summary

An accessory for communication and a network system using the same are disclosed. More specifically, a device and system that enable the Internet of Things to be realized without changing existing electric home appliances and environments are disclosed. The accessory includes a main body having a communication module for communicating with a predetermined network to transmit and receive a signal over the predetermined network and a container having a main body-coupling portion to which the main body is separably coupled. The main body includes at least one selected from between a remote control module for transmitting an optical signal for controlling a predetermined apparatus and a sensor module for sensing predetermined surrounding conditions. The container includes an external coupling portion formed so as to be attached to an external object. In addition, a network system is capable of being realized using an accessory including both the remote control module and the sensor module. The network system includes a server for receiving information about the surrounding conditions of one of two main bodies from the one main body and transmitting a signal for controlling an apparatus at which the other main body is disposed to the other main body based on the sensed information.
