Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Bluetooth and Wi-Fi modules are installed in the cook top for wireless communication, then remote control and monitoring capability is improved, but signal interference between modules increases

Engineering Contradiction:

Improveremote control capabilityVSAvoidsignal interference

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the communication system into separate Bluetooth and Wi-Fi modules, each handling specific communication tasks. The Bluetooth module manages communication with the range hood, while the Wi-Fi module handles communication with the user terminal device, segmenting the communication functions to reduce interference between different wireless protocols

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by positioning the Bluetooth and Wi-Fi modules at different physical locations within the cook top structure. This spatial separation creates distinct local communication zones for each module, reducing electromagnetic interference while maintaining wireless communication functionality

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If multiple communication modules are integrated in the cook top, then IoT integration and remote monitoring are improved, but device complexity increases

Engineering Contradiction:

ImproveIoT integrationVSAvoidcommunication module integration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The processor serves multiple functions by managing both Bluetooth and Wi-Fi communication protocols, controlling the cooker operation, and coordinating communication between the range hood and user terminal device. This multi-functionality reduces the need for separate dedicated controllers for each communication protocol

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The communicator acts as an intermediary component that mediates between the processor and external devices. It handles the complexity of wireless communication protocols and data transmission, shielding the processor from direct implementation details of Bluetooth and Wi-Fi communications

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A cook top includes an inputter configured to receive input of a user manipulation, and a cooker configured to heat a cooking device placed on the cook top. A communicator is configured to perform communication with a user terminal device and a range hood. A processor is configured to: control an operating state of the cooker according to the user manipulation, transmit a signal for controlling an operating state of the range hood to correspond to the operating state of the cooker to the range hood, and control the communicator to transmit state information of the cook top that includes information of the operating state of the cooker to the user terminal device.
