Electric Bed with Swingable Butt Frame for Ergonomic Waist Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric beds fail to effectively support the waist of users, leading to tense muscles and potential long-term damage due to inadequate ergonomic alignment during sitting or lying postures.
Innovation Solution
An electric bed design featuring a swingable back frame and a butt frame driven by actuators, allowing for adjustable posture changes and waist support to conform to ergonomic standards, including a base, back frame, first actuator between the base and back frame, and a second actuator between the base and butt frame for swinging the butt frame to provide waist support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electric beds have a swingable back portion, then the user can change posture between sitting and flat lying, but the waist is not effectively supported and remains in tense condition
Solution Approach 1:
The bed frame is divided into multiple independent swingable sections: a back frame for upper body support and a butt frame for lower body support. This segmentation allows each section to perform its specific function independently, with the butt frame specifically designed to push the waist while the back frame handles posture adjustment.
Solution Approach 2:
The butt frame acts as an intermediary component between the base and the user's waist area. It specifically targets the waist region by swinging upward to push the user's buttocks and waist, providing targeted support that conventional beds lack.
2Device complexity
If conventional electric beds lack waist-pushing function, then the structure remains simple, but the waist muscle stays in tense and systolic condition leading to potential damage
Solution Approach 1:
The butt frame is designed to be dynamically swingable rather than fixed, allowing it to move upward to push the user's waist and then return to its initial position. This dynamic movement enables the bed to actively support the waist muscle, transforming it from a static structure to an active support system.
3Reliability
If the butt frame is added to provide waist support, then waist support effectiveness improves, but the device complexity increases
Solution Approach 1:
The butt frame is merged with the existing base and back frame structure through shared mounting mechanisms and actuators. The second actuator is integrated into the same spatial plane as the first actuator, and both frames share common mounting hardware, reducing the actual complexity increase despite adding functional capability.

AI summary
An electric bed includes a base, a back frame, and a butt frame. The rear end of the back frame is attached to the base, and the back frame is swingable relative to the base by the driving of a first actuator. The butt frame is located in back of the back frame. The rear end of the butt frame is attached to the base, and the butt frame is swingable relative to the base by the driving of a second actuator. As a result, the electric bed of the invention enables the user to change the posture thereof between sitting and flat lying postures through the swinging of the back frame, and effectively supports the waist of the user through the swinging of the butt frame, so that the user can maintain the posture thereof conforming to ergonomics, thereby prevented from hurt on the waist.
