Device for making bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of making beds in large accommodation settings, such as hotels, is labor-intensive and time-consuming due to the manual stretching and securing of sheets and duvet covers over mattresses, requiring significant personnel hours and increasing operational costs.
Innovation Solution
A device comprising four parts fixed at the corner areas of a mattress, with upper and lower sections and a resilient biasing device, allows for easy and secure attachment and tightening of sheets and duvet covers, simplifying the bed-making process by utilizing elastic members or telescopic parts for adjustable tension and incorporating spring reel retractors and crocodile clips for efficient sheet and blanket changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual stretching and securing of sheets and duvet covers is used, then the bed making process can be completed, but it requires significant personnel hours and is labor-intensive
Solution Approach 1:
The device enables the sheet and duvet cover to be automatically stretched and secured over the mattress through the resilient biasing devices that self-actuate to tension the textile material, eliminating the need for manual stretching operations and significantly reducing personnel time requirements
Solution Approach 2:
The fixing devices are pre-positioned at the corner areas of the mattress, and the resilient biasing devices are pre-configured to exert tensioning force. When the sheet is attached, the biasing devices automatically engage to stretch and secure the material in advance of final positioning, streamlining the bed making process
2Ease of operation
If fixing devices with resilient biasing devices are used, then sheets can be quickly stretched and secured, but the device structure becomes more complex
Solution Approach 1:
The device is divided into four separate parts, each positioned at a corner area of the mattress. Each part contains its own fixing device and resilient biasing device, allowing independent operation and attachment. This segmentation simplifies the overall operation while distributing the mechanical complexity across multiple simple, identical units
Solution Approach 2:
Instead of using complex mechanical systems to hold the sheet in place, the invention uses resilient biasing devices that naturally exert outward tensioning force. The fixing devices are designed to release and engage easily, inverting the traditional approach where complex locking mechanisms are required. The simplicity of attachment is achieved by allowing the biasing device to do the work of stretching while the fixing device merely provides attachment points
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Significantly reduces the time and effort required for bed making, enabling faster and more efficient bed preparation, thereby lowering operational costs and enhancing productivity in accommodation services.
Implementation Method 1
a resilient biasing device, which biasing device allows the fixing means to be moved away from the part and to return to the part once released
Implementation Method 2
The elastic members or parts allow tensioning of the upper and lower sections of the part at the corners of the mattress against the corresponding upper and lower surface of the mattress
