Mattress Roll Together Testing Using Weighted Cylinders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively quantify and compare the 'roll together' phenomenon in mattresses, making it difficult to assess and prevent the undesirable rolling together of couples during sleep, especially at the time of purchase.
Innovation Solution
A method involving positioning and moving weighted cylinders on a mattress to measure changes in angle, using an inclinometer and displacement measurement system to determine the roll together movement metric, allowing for the quantification and comparison of roll together characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate mattresses are used for each person, then roll together is prevented, but support profile unevenness and firmness discomfort occur at the joining region
Solution Approach 1:
The patent combines two separate mattress systems into a single unified mattress structure with a continuous support profile. The mattress includes a base layer and a comfort layer that span the entire width, eliminating the joining region between separate mattresses while maintaining individualized support zones through variable firmness regions designed to prevent roll together.
Solution Approach 2:
The mattress incorporates regions of different firmness within a single unified structure. Specifically, it includes softer regions near the center and firmer regions toward the edges, or vice versa depending on the design, allowing each sleeping zone to have optimized local characteristics while maintaining overall structural uniformity and preventing roll together.
2Ease of manufacture
If traditional mattress constructions are used, then manufacturing is simpler, but ability to quantify and compare roll together resistance is insufficient
Solution Approach 1:
The patent replaces subjective human assessment of roll together with an automated mechanical testing system. The apparatus uses weighted members, displacement sensors, and force measurement devices to objectively quantify roll together resistance through controlled simulation of couple sleeping conditions, providing precise measurable data while maintaining practical testing procedures.
Solution Approach 2:
The testing method varies key parameters such as weight magnitude, positioning distance between weights, and measurement intervals to comprehensively characterize roll together resistance. By systematically changing these parameters and measuring the resulting mattress deformation and force requirements, the system generates quantitative performance data that enables precise comparison between different mattress constructions.
3Measurement precision
If couples sleep on the mattress for a period of time, then roll together assessment is possible, but purchase decision timing is delayed
Solution Approach 1:
The patent performs preliminary testing of roll together resistance during the manufacturing quality control process, before the mattress reaches the consumer. The automated testing system simulates couple sleeping conditions and measures roll together resistance, generating quantitative performance data that is available at the point of purchase, eliminating the need for extended trial periods.
Solution Approach 2:
The testing apparatus creates a simplified copy or model of the actual couple sleeping scenario using weighted members positioned on the mattress. This model simulation reproduces the essential mechanics of roll together without requiring actual human subjects, allowing rapid objective assessment that can be completed during manufacturing quality control.
