Remote Cooking Appliance Control via Authenticated Server Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for remote control of cooking appliances lack a centralized intermediary server for secure and unified control, limiting multi-appliance management and user access.
Innovation Solution
A system with a central intermediate server that processes and transmits control instructions through a bidirectional communications network, integrating local control means in cooking appliances and user computing devices, ensuring secure operation by verifying user and appliance identities, and managing multiple appliances and users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If direct connection between cooking appliance and remote control device is established, then communication speed is improved, but security and centralized control are worsened
Solution Approach 1:
The patent introduces a server as an intermediary component that mediates all communications between remote control devices and cooking appliances. The server receives control instructions from remote devices, processes them through authentication and validation, then transmits approved instructions to the target appliances. This intermediary architecture maintains centralized control and security while enabling remote operation, resolving the contradiction between direct communication speed and secure centralized control.
2Adaptability or versatility
If multiple appliances are controlled directly by remote devices, then device versatility is improved, but system complexity and authentication management are worsened
Solution Approach 1:
The patent merges authentication, authorization, and appliance management functions into a single centralized server. Instead of implementing these functions in each appliance or remote device, the server consolidates user credential verification, appliance registration, permission management, and instruction routing. This consolidation enables versatile multi-appliance control while simplifying the overall system architecture and reducing the complexity of authentication management across multiple devices.
3Reliability
If centralized server processing is implemented, then security and control management are improved, but communication latency and response time are worsened
Solution Approach 1:
The patent implements preliminary action by pre-registering appliances with the server and establishing authentication credentials before actual cooking operations. User profiles, appliance permissions, and communication channels are set up in advance. When cooking operations need to be controlled remotely, the pre-established connections and credentials enable rapid instruction transmission without real-time authentication delays, thus maintaining security while reducing operational latency.
