Sickbed Control Panel Integrating Light Module and Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients on sickbeds often struggle to reach light switches on the wall, requiring assistance, and existing light sources either provide excessive illumination disturbing others or insufficient light for reading or working.
Innovation Solution
A control panel with integrated light and height adjustment capabilities, featuring a casing with opposing surfaces for a light module and control module, allowing patients to easily operate lights and adjust bed height without leaving their bed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a light switch is provided on the wall above the sickbed, then the patient can control the lamp, but the patient cannot reach the light switch easily when lying on the sickbed
Solution Approach 1:
The patent combines the light switch function with the control panel that is already positioned within the patient's reach. The control panel integrates both height adjustment controls and light switching capabilities into a single accessible location, eliminating the need for the patient to reach for a separate wall-mounted light switch.
Solution Approach 2:
The control panel is designed to perform multiple functions: adjusting sickbed height and controlling lighting. By making the control panel universal for both control and lighting functions, the patent eliminates the need for separate controls and improves ease of operation for patients who cannot reach wall-mounted switches.
2Illumination intensity
If a fluorescent lamp with large illumination range is installed above the sickbed, then sufficient light is provided for reading and working, but other patients on adjacent sickbeds are disturbed
Solution Approach 1:
The patent provides a local light source on the control panel that illuminates only the immediate area where the patient needs to read or work, rather than providing broad-area illumination. This localized lighting approach ensures sufficient light for the patient's tasks while preventing disturbance to other patients on adjacent beds.
Solution Approach 2:
The lighting function is extracted from the ceiling-mounted fluorescent lamp and relocated to the control panel. This allows the light source to be positioned locally near the patient's working area, providing illumination only where needed and eliminating the harmful effect of disturbing other patients.
3Object-affected harmful factors
If a night lamp with small illumination range is used, then other patients are not disturbed, but insufficient light is provided for reading and working
Solution Approach 1:
The control panel incorporates a switchable light source that can dynamically adjust its illumination range based on the patient's needs. The patient can select between different lighting modes or intensities through the control panel, allowing the illumination range to be dynamically adjusted to match the specific task requirements while maintaining privacy.

AI summary
A control panel of a sickbed having a light source is disposed around a sickbed and includes a casing, a light module and a control module. The light module and the control module are provided on two opposite surfaces of the casing respectively. The control module is electrically connected to the light module for controlling the height of the sickbed and an ON/OFF state of the light module. The control panel of the present invention is used to adjust the height of the sickbed and also provides illumination, so that it really demonstrates practicability and convenience.
