Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a refrigerator is used as a smart home controller, then power supply stability is improved, but device complexity increases

Engineering Contradiction:
Improvepower supply stabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The refrigerator is designed to perform multiple functions: it maintains its primary refrigeration function while simultaneously serving as a smart home controller. The control unit within the refrigerator can receive control information from portable devices and transmit operation signals to other home appliances, making the refrigerator a universal device that combines food storage with home automation control capabilities.

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

Solution Approach 2:

The refrigerator acts as an intermediary device between portable devices (smartphones, tablets) and other home appliances. The control unit in the refrigerator receives control information from portable devices, processes it, and then transmits appropriate operation signals to target home appliances, thereby mediating the control interaction and simplifying the overall system architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If multiple remote controls are replaced by a single refrigerator controller, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Multiple remote control functions are merged into a single refrigerator controller. Instead of having separate remote controls for different home appliances, the refrigerator's control unit consolidates these functions by receiving control information for multiple appliances and transmitting the appropriate operation signals, thereby reducing the number of remote controls needed and simplifying user interaction.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The refrigerator controller is designed with universal functionality to control various types of home appliances (air conditioners, televisions, audio equipment, etc.). The control unit can interpret control information for different appliances and generate corresponding operation signals, making a single device capable of replacing multiple appliance-specific remote controls.

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

3Adaptability or versatility

If the refrigerator controls home appliances through communication protocols, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The refrigerator's control unit is equipped with multiple communication protocol capabilities (infrared, Bluetooth, Wi-Fi) to interface with different types of home appliances. This multi-functional communication capability allows the refrigerator to adapt to and control various appliances using their respective protocols, enhancing system versatility.

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

Solution Approach 2:

The refrigerator serves as a communication intermediary that translates between different protocol types. It receives control information from portable devices via one protocol (e.g., Wi-Fi or Bluetooth), processes the information, and transmits operation signals to home appliances using their native protocols (e.g., infrared for air conditioners), thereby mediating protocol compatibility.

Inventive Principle:
Principle #24Intermediary (Mediator)
