Integrated Sickbed Remote Control with Emergency Calling Knob
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controls for sickbeds lack the ability to call medical personnel urgently and are inconvenient to use, with independent power supplies and components that complicate emergency communication and monitoring.
Innovation Solution
A remote control for sickbeds with a holding plate, transmission mechanism, and wireless communication module, including a microcontroller unit, calling knob, and operational panel, allowing for programmable control of the sickbed's angle and wireless communication with a remote management platform for easy caregiver calling and care monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional remote control is provided to control the sickbed angle, then the sickbed can be adjusted, but the remote control cannot be used to call medical personnel urgently
Solution Approach 1:
The patent combines the call bell function and remote control function into a single integrated device. The calling assembly with calling knob is merged with the remote control body that contains the operational panel for controlling sickbed angle, eliminating the need for separate independent components and power supplies.
Solution Approach 2:
The remote control device is designed to perform multiple functions: it can both adjust the sickbed angle through the operational panel and call medical personnel through the calling knob. This multi-functional design allows a single device to replace multiple separate components.
2Ease of operation
If the call bell and remote control are independent components with independent power supplies, then each component can function separately, but patients are not easy to distinguish during emergency use and the remote control is operated inconveniently
Solution Approach 1:
The patent merges the call bell and remote control into a single integrated unit with a unified power supply. The calling assembly and operational panel are housed in the same remote control body, reducing the number of independent components from two to one.
Solution Approach 2:
The integrated remote control serves dual purposes: emergency calling through the calling knob and sickbed angle adjustment through the operational panel. This eliminates the need for patients to distinguish between separate components and simplifies operation.
3Reliability
If the remote control lacks wireless communication capability, then the device structure remains simple, but the sickbed cannot provide instant safety care and monitoring
Solution Approach 1:
The patent replaces traditional wired communication or mechanical signaling systems with wireless communication technology. The wireless communication module enables instant transmission of calling signals and data to the remote management platform without physical connections, enhancing emergency response capability.
4Reliability
If the calling knob is always accessible, then emergency calling is immediate, but the calling knob may be pressed accidentally or without intention
Solution Approach 1:
The switch is designed to require a deliberate action (pushing to move away from the calling knob) to activate the calling function. This preliminary action ensures that the calling signal is only sent when the patient intentionally wants to call, preventing accidental activations while still allowing quick response when needed.

AI summary
A remote control for a sickbed contains: a body, a calling assembly, an operational panel, and a switch. The body includes a power supply set, a microcontroller, a calling knob, and a wireless communication module. The operational panel includes multiple buttons so that when pressing any one of the multiple buttons, the microcontroller starts the transmission mechanism to actuate the sickbed to lift or descend. The switch is arranged on the body and moves close to or away from the calling knob. When the switch is pushed to abut against the calling knob, the calling knob is maintained on a locking position and does not generate a calling signal. When the switch is pushed to move away from the calling knob, the calling knob is maintained on a starting position and is pressed to conduct the power and to send the calling signal.
