Innovation Solution
A system comprising a remote control device and a safety control device connected via a single wireless connection, where the remote control device generates processed information using a first secret, and the safety control device verifies the closed state of a switch using a matching second secret, ensuring safe operation of the medical device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wireless transmitter/receiver pairs are used to ensure safety, then safety reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple wireless communication functions into a single wireless connection between the remote control device and safety control device. The single connection integrates control signals and safety verification data, eliminating the need for separate transmitter/receiver pairs while maintaining safety through encrypted communication protocols and authentication mechanisms within the unified connection.
Solution Approach 2:
The single wireless connection is designed to perform multiple functions simultaneously: transmitting control commands, verifying safety conditions, exchanging authentication data, and monitoring system status. This multi-functional approach replaces what would traditionally require multiple dedicated communication channels, reducing system complexity while preserving safety reliability.
2Ease of operation
If wireless control is used to improve ease of operation, then ease of operation is improved, but safety reliability deteriorates due to software errors and transmission issues
Solution Approach 1:
The patent introduces an encrypted communication channel as an intermediary between the remote control device and the medical device. This intermediary layer protects against software errors and transmission issues by implementing error detection, authentication, and secure data exchange protocols, thereby maintaining safety reliability while preserving the ease of wireless operation.
Solution Approach 2:
The system implements continuous feedback mechanisms where the safety control device verifies received commands and transmits status information back to the remote control device. This feedback loop includes authentication verification, command validation, and system state monitoring, ensuring that wireless control operations maintain safety reliability through real-time verification and correction capabilities.

AI summary
A system for controlling a device is provided. The system may include a remote control device and a safety control device communicating with each other via a wireless connection. The remote control device may be configured to remotely control the device. The remote control device may include a switch, a motion enable unit, and a hand control unit. The motion enable unit may be configured to generate processed information by processing information using a first secret. The hand control unit may be capable of acquiring the processed information from the motion enable device only when the switch is in a closed state. The hand control unit may be configured to transmit the processed information to the safety control device via the wireless connection. The safety control device may include a communication unit and a safety control unit. The communication unit may be configured to receive the processed information via the wireless connection. The safety control unit may be configured to verify the closed state of the switch by processing the processed information using a second secret that matches the first secret. Further, the safety control unit may be configured to enable control of the device when the closed state of the switch is verified.
