Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If acoustic communication is implemented between home appliances and mobile terminals, then user convenience and ease of operation are improved, but device complexity increases due to integration of communication functions
Solution Approach 1:
The home appliance integrates multiple functions including acoustic communication, display output, and information processing into a single device. The appliance can function as both a traditional home appliance and a communication device, eliminating the need for separate communication modules and reducing overall system complexity while improving user convenience.
Solution Approach 2:
The patent combines the communication function with the existing home appliance structure by integrating the acoustic communication unit, display unit, and controller into the appliance's existing architecture. This merging approach allows information transmission without adding separate communication devices, thereby improving ease of operation while managing device complexity.
2Ease of manufacture
If acoustic communication is used for information transmission, then manufacturing costs are reduced by eliminating separate wireless modules, but information transmission reliability may be affected
Solution Approach 1:
The patent uses sound waves as an intermediary medium for information transmission between the mobile terminal and home appliance. By modulating information onto acoustic signals and using the display unit as a visual intermediary, the system achieves reliable communication without requiring expensive wireless communication modules, thus reducing manufacturing costs while maintaining transmission reliability.
Solution Approach 2:
The information is copied from the mobile terminal's display to the home appliance's display through acoustic communication. The home appliance receives and reproduces the displayed information on its own display unit, creating a visual copy that ensures accurate information transmission without relying on complex wireless protocols or additional hardware.
3Loss of information
If the home appliance outputs sound containing information, then information transmission capability is improved, but sound intensity may cause discomfort or security issues
Solution Approach 1:
The patent employs partial action by using only the necessary acoustic output level required for information transmission without exceeding what is needed. The acoustic communication unit outputs sound at controlled intensity levels that are sufficient for the mobile terminal to receive and process the information, avoiding excessive sound intensity that could cause discomfort or security issues while maintaining effective information transmission.
