Secure Remote Control of Electrical Devices via Access Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical devices with control features located directly on the device pose security risks and practical challenges when not easily accessible, as they can be inadvertently or improperly operated, leading to unintended consequences such as device malfunction or unauthorized access.
Innovation Solution
An electrical device with an integrated control interface and an access controller that allows for secure remote control by verifying user identity and authority through various communication methods, enabling control of the device components without physical interaction, thus preventing unauthorized access and ensuring secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control features are located directly on the electrical device, then ease of operation is improved, but security and reliability deteriorate due to unauthorized or inadvertent operation
Solution Approach 1:
The patent introduces an access controller as an intermediary component that mediates between the user and the electrical device components. The access controller receives communications from sensors, verifies user authority, and then controls the electrical device components accordingly, preventing unauthorized direct access while maintaining operational convenience.
Solution Approach 2:
The patent segments the control system into distinct functional components: sensors for receiving user input, an access controller for authentication and decision-making, and electrical device components for execution. This segmentation allows the access controller to enforce security policies while enabling legitimate operations.
2Ease of operation
If control features are located directly on the electrical device, then ease of operation is improved, but harmful factors increase due to inadvertent operation
Solution Approach 1:
The access controller performs preliminary verification of user authority before allowing operation of electrical device components. By checking authentication credentials in advance, the system prevents inadvertent or malicious operations that could cause harmful effects, while still allowing authorized users to operate the device conveniently.
3Ease of operation
If remote control is implemented without authentication, then ease of operation is improved, but security deteriorates due to unauthorized access
Solution Approach 1:
The access controller serves as an intermediary that enables remote control functionality while maintaining security. It receives communications from sensors that identify users and their instructions, verifies authority based on the identification, and then executes the control instructions, thus allowing remote operation only for authorized users.
4Reliability
If access control mechanisms are added, then security is improved, but device complexity increases
Solution Approach 1:
The patent merges the access control functionality with the existing sensor and control infrastructure of the electrical device. The access controller integrates with sensors already present for other functions and combines authentication logic with control signal generation, reducing overall system complexity compared to implementing separate access control and control systems.
