Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user directly manipulates the electric appliance, then the control is simple and direct, but the user must be physically present at the appliance location
Solution Approach 1:
The patent introduces a control device as an intermediary between the user and the electric appliance. This control device communicates with the appliance via a network, allowing the user to control the appliance remotely without being physically present. The control device transmits control signals to the appliance and receives status information, effectively mediating the interaction between user and appliance.
Solution Approach 2:
The patent adds a spatial dimension to the control interaction by enabling remote control through network communication. Instead of requiring the user to be at the same physical location as the appliance, the control can be performed from any location with network connectivity, effectively moving the interaction to a different spatial dimension.
2Adaptability or versatility
If the electric appliance is accessible to all users, then the availability is high, but the security and user-specific control are reduced
Solution Approach 1:
The patent implements user-specific control by associating each user with specific control permissions and identification information. The control device uses user identification to establish authenticated connections with the appliance, ensuring that only authorized users can control specific appliances. This creates localized access control where different users have different levels of access to different devices.
3Loss of information
If the user monitors the appliance in the vicinity, then the monitoring is direct and real-time, but the user cannot be at a distance
Solution Approach 1:
The control device acts as an intermediary for information transmission between the appliance and the user. It receives operation information from the appliance via network communication and displays it to the user, enabling remote monitoring without requiring the user to be physically near the appliance. This mediator approach maintains real-time information flow across distance.
4Reliability
If the connection process is complex, then the security is enhanced, but the ease of use is reduced
Solution Approach 1:
The patent implements preliminary authentication by requiring user identification information to be set in advance on both the control device and the appliance. This preliminary action establishes secure connections before actual control operations, ensuring that only authenticated users can control the appliance while maintaining a relatively simple user experience during normal operation.
