Motorized Bed With Touch Screen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hospital beds cannot transition a patient from a fully reclined position to a completely vertical position without physical effort from the patient or caregiver, limiting patient mobility and comfort.
Innovation Solution
A bed equipped with primary and secondary motors operated via a touch screen, allowing for smooth transitions between lying down, sitting, standing, and vertical positions, along with continuous leg movement and rocking functions, utilizing a tubular frame, mattress base, and strategically placed pivot points for seamless movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hospital bed uses manual levers and ropes for position adjustment, then the device complexity is reduced, but the ease of operation deteriorates as patients cannot independently adjust positions
Solution Approach 1:
The patent replaces manual mechanical systems (levers, ropes, wheels) with an automated motorized system controlled by a microprocessor and touch screen interface. Motors are coupled to the bed frame segments to automatically adjust positions, eliminating the need for manual operation while providing independent patient control through electronic interfaces.
Solution Approach 2:
The bed enables patients to independently adjust their own positions through touch screen controls without requiring caregiver assistance. The automated motorized system responds to patient input, allowing self-service position adjustment for various therapeutic and comfort needs.
2Adaptability or versatility
If a hospital bed lacks vertical position capability, then the device complexity is reduced, but the adaptability deteriorates as patients cannot transition to standing positions
Solution Approach 1:
The bed incorporates dynamic positioning capabilities that allow continuous adjustment from horizontal to vertical positions. The motorized system with multiple degrees of freedom enables the bed frame segments to move independently, achieving various angles including complete vertical positioning for standing patients.
Solution Approach 2:
The bed is designed to perform multiple functions including horizontal positioning, vertical positioning, and intermediate angles. The motorized system with microprocessor control provides universal positioning capability to accommodate various patient needs from supine to standing positions.
3Ease of operation
If a hospital bed uses touch screen and motorized control, then the ease of operation is improved, but the use of energy increases due to continuous motor operation
Solution Approach 1:
The motorized system operates periodically rather than continuously, activating motors only when position changes are required through touch screen input. The microprocessor controls motor activation in discrete cycles, reducing overall energy consumption compared to continuous operation while maintaining ease of use.

AI summary
The present invention relates to a long-term bed designed to support patient recovery by offering multiple positions to make the patient's stay more comfortable. These multiple positions help reduce pressure points to prevent the formation of bedsores on the patient's skin. Additionally, the bed aids patient recovery by providing continuous leg movement exercises, which prevent the loss of mobility and the potential formation of blood clots. The bed is equipped with a touch screen that the patient can operate independently or with the help of a family member. The touch screen will feature a specific program allowing the bed to adopt the following positions: lying down with extended legs, standing with extended legs, lying down with raised legs, lying down with extended legs, continuous leg movement in the lying position, and continuous back movement from horizontal to inclined in a seated position.
