Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine-to-machine communication techniques are used for remote control, then communication capability is achieved, but system complexity increases
Solution Approach 1:
The patent introduces a control device as an intermediary between the user's mobile terminal and the appliances. This mediator handles the complex M2M communication protocols and appliance-specific protocols, shielding the user from complexity while enabling reliable communication. The control device translates between different communication standards and manages the interaction flow.
Solution Approach 2:
The control device automatically detects the mobile terminal's presence and triggers command execution without requiring user intervention. The system self-manages the communication sequence, from detecting terminal entry to selecting and executing appropriate commands, reducing operational complexity for the user.
2Ease of operation
If automated detection of mobile terminal is implemented, then user interaction is reduced, but detection complexity increases
Solution Approach 1:
The patent combines the radio detection functionality with the existing control device that already manages appliance communication. By merging the detection capability into the control device, the patent avoids adding separate detection hardware, thereby reducing overall system complexity while achieving automated user interaction.
Solution Approach 2:
The control device is designed to perform multiple functions: it serves as a radio detection point for detecting mobile terminals, acts as a communication gateway for M2M protocols, and functions as an appliance controller. This multi-functionality eliminates the need for separate dedicated detection devices, simplifying the overall system architecture.
3Adaptability or versatility
If multiple communication modes are integrated, then appliance compatibility increases, but system complexity increases
Solution Approach 1:
The control device acts as a protocol mediator that handles multiple communication modes (M2M protocols, radio communication, appliance-specific protocols). It translates between different protocol formats and manages the complexity of interfacing with various appliance types, enabling broad compatibility without requiring each appliance to support multiple protocols.
Solution Approach 2:
The patent segments the communication functionality into distinct layers: the control device handles protocol translation and command routing, while appliances operate with their native protocols. This segmentation allows each component to be optimized independently, maintaining simplicity at the appliance level while achieving versatility through the control device's multi-protocol capability.
Data Source
AI summary
A method of remotely controlling at least one domestic appliance, remote control of such domestic appliances is triggered automatically by detecting a mobile communications terminal entering or leaving a radio reception perimeter of a control device. The control device is a home gateway or more simply a modem provided with a radio access unit.
