Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock and switch systems face limitations in remote control and access management, particularly when offline or without wireless communication, leading to issues with duplication, loss, rigidity, and connectivity concerns.
Innovation Solution
A lock and switch controller system with offline responsiveness and flexible commands that integrates operation logic and electronic circuitry, allowing administrators to remotely control locks and switches without direct access or wireless communication, using a code generator to produce encrypted tokens for controlling access units and appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication and internet connectivity are used for remote access control, then ease of operation and remote management capability are improved, but device complexity and connectivity dependency increase
Solution Approach 1:
The system pre-loads encrypted commands and access control logic into the controller's local memory before offline operation is needed. When offline mode is activated, the controller executes these pre-stored commands locally without requiring real-time wireless communication, thus maintaining remote management capability while eliminating connectivity dependency during critical operations
Solution Approach 2:
An encrypted command token acts as an intermediary carrier that contains all necessary control instructions. This token is generated in advance with full operational details embedded, allowing the controller to interpret and execute complete control sequences locally without needing continuous external communication, thereby reducing device complexity while preserving ease of operation
2Device complexity
If traditional key-based access systems are used, then device complexity is low, but loss and duplication issues arise
Solution Approach 1:
Instead of relying on physical keys that can be lost or duplicated, the system uses encrypted digital command tokens as virtual copies of access authority. These tokens can be generated, transferred, and executed without physical duplication risks. The encryption ensures that even if tokens are intercepted or copied, they cannot be used without the proper decryption key, thus maintaining security while eliminating the problems of traditional key-based systems
Solution Approach 2:
The patent replaces the mechanical key-based access system with an electronic encryption-based system. Physical keys are substituted with encrypted digital commands that can be transmitted wirelessly or stored securely. This substitution eliminates the mechanical vulnerabilities of key duplication and loss while maintaining the simplicity of the access control mechanism through automated encrypted command execution

AI summary
A lock and switch controller system, a lock and switch device with offline responsiveness, and system with flexible commands are present. The disclosure provides a lock and/or switch and controller system having a controller with a means of receiving readable alpha and/or numeric input manually from a user using a keypad or other means. The apparatus disclosed herein, provides for the compilation of commands, encrypted in the form of human readable tokens containing covert instructions for the remote control and management of target devices. Any instructions to an appliance or any other users' credentials can be encrypted by an administrator and/or owner and delivered to the controller of the appliance by a user without compromising any security. The lock and switch controller system operates independently and can accept new rules without the presence of the administrator or owner and without connectivity to any communications network.
