Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for devices like robots do not effectively manage multiple users controlling the same device independently and securely, leading to issues with access management and control command coordination.
Innovation Solution
A wireless remote control system that includes processors, memories, and user input interfaces in controlling devices, allowing for secure pairing, access management, and command coordination among multiple users, with mechanisms for handling connection losses and redirecting control when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users control the same remote device independently using separate remote control devices, then the versatility and collaboration capability are improved, but the access management and control coordination become more complex
Solution Approach 1:
The system segments control authority by designating one remote control device as primary and others as secondary. The primary device handles direct communication with the remote device, while secondary devices communicate through the primary device, creating a hierarchical control structure that simplifies access management while enabling multi-user control
Solution Approach 2:
The primary remote control device acts as an intermediary between secondary remote control devices and the remote device. Secondary devices send control commands to the primary device, which then forwards them to the remote device, eliminating the need for each secondary device to establish direct connections and simplifying access management
2Ease of operation
If multiple remote control devices connect directly to the remote device, then the ease of operation is improved, but the control command coordination and access security deteriorate
Solution Approach 1:
The system segments control pathways by creating a primary control channel (secondary devices to primary device) and a secondary control channel (primary device to remote device). This segmentation maintains independent operation capability while ensuring coordinated control through the hierarchical structure
Solution Approach 2:
The primary remote control device receives control commands from secondary devices, processes them, and forwards appropriate commands to the remote device. This feedback mechanism ensures that control actions are coordinated and that the system state is maintained consistently across all connected devices
3Reliability
If the system implements secure pairing and access management for multiple devices, then the security is improved, but the device complexity and pairing process duration increase
Solution Approach 1:
The system performs preliminary pairing between the primary and remote control devices first, establishing a secure baseline connection. Secondary devices are then paired with the primary device rather than directly with the remote device, simplifying the overall pairing process while maintaining security through the hierarchical structure

AI summary
In one embodiment, a first controlling device includes a processor to send a first pairing request to a remote device, receive a grant of access from the remote device, receive user input commands, receive a second pairing request from a second controlling device, grant access to the second controlling device, receive control commands from the second controlling device, and send control commands to the remote device based on the control commands received from the second controlling device and the user input commands, after the first controlling device loses a connection with the remote device, the processor being operative to send a third pairing request to the remote device and receive a denial of the third pairing request and an identification of the second controlling device from the remote device, send a fourth pairing request to the second controlling device, receive a grant of access from the second controlling device.
