Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional treatment beds with integrated structures face challenges in storage and transportation due to their size, occupying space and complicating indoor use when not in use.
Innovation Solution
A foldable bed structure with a body and leg frame, equipped with actuators, guide rollers, and sliding rails, allowing for automatic vertical and horizontal movement, enabling easy folding and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bed is made with an integrated structure to ensure stability and strength, then the structural integrity is improved, but the ease of storage and transportation deteriorates due to large space requirements
Solution Approach 1:
The bed frame is divided into multiple separable components including a head frame, a foot frame, and adjustable leg assemblies that can be detached and reattached. This segmentation allows the bed to be disassembled into smaller parts for compact storage and easy transportation while maintaining structural integrity when assembled
Solution Approach 2:
The bed design incorporates vertical adjustability through telescopic legs and height-adjustable components, allowing the bed to occupy different vertical spaces. When not in use, the bed can be collapsed to a compact height, effectively utilizing vertical dimension for storage efficiency without compromising strength
2Reliability
If the bed is designed with a fixed structure to maintain stability during use, then the reliability is improved, but the ease of operation deteriorates due to difficulty in folding and moving
Solution Approach 1:
The bed incorporates adjustable and movable components including telescopic legs with locking mechanisms, adjustable head and foot sections, and removable side rails. These dynamic elements allow the bed to transition between stable fixed positions during use and flexible configurations for folding and storage, balancing reliability with ease of operation
3Adaptability or versatility
If the bed frame is manufactured with a certain length to support full body length, then the functionality is improved, but the ease of manufacture and transportation deteriorates due to long dimensions
Solution Approach 1:
The long bed frame is segmented into transportable sections that can be manufactured separately and assembled on-site. The head frame, foot frame, and intermediate sections are designed as modular units that connect through standardized joints, enabling easy assembly while reducing transportation complexity and manufacturing difficulty
