Knockdown adjustable bed with a slidable assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adjustable beds with fixed lengths can cause discomfort when the upper portion is lifted, as the abdomen is pressed due to the lack of length adjustment, which is not adequately addressed by existing designs.
Innovation Solution
The adjustable bed incorporates a power operation system with a headrest and lumbar operation system, featuring a slidable assembly that allows the head lift platform to extend or retract, along with a lumbar lift mechanism, driven by motors, to adjust the bed's length and provide lumbar support, ensuring comfortable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper portion of the adjustable bed is lifted, then the headrest position is adjusted, but the fixed bed length causes abdominal pressure
Solution Approach 1:
The patent applies the dynamics principle by making the bed platform length adjustable rather than fixed. The power operation system enables the bed platform to dynamically extend or retract in response to positioning needs, allowing the upper portion to be lifted for headrest adjustment without maintaining a fixed length that would cause abdominal pressure.
2Object-affected harmful factors
If a power operation system is added to enable length adjustment, then abdominal pressure is prevented, but device complexity increases
Solution Approach 1:
The patent applies the universality principle by designing a power operation system that performs multiple functions: it adjusts the bed platform length to prevent abdominal pressure, positions the headrest, and provides lumbar support. This multi-functional approach consolidates several adjustment needs into a single system, reducing overall complexity compared to having separate mechanisms for each function.
Solution Approach 2:
The patent merges the length adjustment mechanism with the existing headrest and lumbar support systems into an integrated power operation system. By combining these functions into a unified system with coordinated control, the patent reduces the number of independent components and control systems needed, thereby managing device complexity while achieving multiple benefits.
