Electric adjustable bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electric beds experience a reduction in bed length when the bed posture is adjusted, leading to a protruding mattress without support, resulting in an unappealing appearance and potentially shorter mattress lifespan.
Innovation Solution
An electric bed with an adjustable bed length design, featuring an upper and lower bed frame with pivotable bedboards, where the upper head and foot bed frames are separated, allowing a moving component to adjust the distance between them based on the pivoting angle of the bedboards, ensuring continuous support and maintaining a pleasing appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bedboards are hinged in end-to-end relation to allow posture adjustment, then the bed body posture can be adjusted, but the bed length is shortened and the mattress protrudes without support
Solution Approach 1:
The patent applies dynamics by making the upper bed frame extendable through a moving component that can slide along guide rails. This dynamic structure allows the bed frame length to adjust automatically in response to bedboard pivoting, maintaining full mattress support throughout the range of motion while enabling various bed body postures.
2Adaptability or versatility
If the bedboards are hinged in end-to-end relation, then the bed can adjust posture, but the protruding mattress results in a bad look and shorter service life
Solution Approach 1:
The dynamic extendable upper bed frame ensures that the bed structure adapts to the pivoting bedboards, maintaining full mattress support at all times. This prevents the mattress from protruding unsupported, thereby preserving its appearance and extending its service life while still allowing posture adjustment.
3Length of stationary object
If the upper head bed frame and upper foot bed frame are separated with a moving component, then the bed length can be adjusted to compensate for pivoting loss, but the device complexity increases
Solution Approach 1:
The upper bed frame is segmented into a head bed frame and a foot bed frame connected by an extendable section with a moving component. This segmentation allows independent adjustment of the frame length to compensate for bedboard pivoting, maintaining mattress support without requiring complete redesign of the entire bed structure.
Solution Approach 2:
The moving component acts as an intermediary between the head and foot bed frames, providing the necessary length adjustment while guiding the extension movement through fixed guide rails. This intermediary structure enables length compensation with relatively simple mechanical elements.

AI summary
An electric bed with an adjustable bed length, containing an upper head bed frame, an upper foot bed frame, a lower bed frame, and a plurality of bedboards. Wherein at least one of the plurality of bedboards is pivotable relative to the lower bed frame. Wherein either of the upper head bed frame and the upper foot bed frame is fixed/immobile relative to the lower bed frame while the other contains a moving component which moves back and forth relative to the lower bed frame between a rest position and an extension position. Wherein the at least pivotable bedboard keeps horizontal and the upper head bed frame is away from the upper foot bed frame by Distance 1 when the moving component is located at the rest position, while the at least one pivotable bedboard pivots and there is Distance 2 between the upper head bed frame and the upper foot bed frame when the moving part is located at the extension position. Wherein Distance 2 is longer than Distance 1. The bed length is adjusted in the above-mentioned way to overcome the defect in the traditional electric bed where the bed length is shortened after the posture is changed, causing part of the matress to have no support basis. Further, the electric bed works reliably with an always pleasing appearance and can be conveniently assembled with a low risk of injury to a user's hand.
