Air Table Sewing Support for Mattress Topper Seam Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mattress toppers are often bulky and prone to seam tears due to stress, and the process of sewing them is challenging due to their weight and difficulty in maneuvering during fabrication.
Innovation Solution
A mattress topper design featuring a lower and upper layer connected by a seam with the side layer bearing the threads, and an air table that lifts the mattress topper during sewing using a top panel with vents and an air supply to reduce stress on the seams and facilitate easier handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mattress topper is used to add cushion and support to mattress, then comfort is improved, but seams are prone to tearing due to stress during use
Solution Approach 1:
The patent applies different fabric types to different locations of the mattress topper. The side layer uses a first fabric type while the top and bottom layers use a second fabric type. This local differentiation allows the seam construction to be optimized for stress-bearing areas, with the side layer bearing the seam threads to prevent tearing at stress points.
2Strength
If mattress topper is made heavy to provide sufficient cushion and support, then comfort is improved, but it becomes difficult to maneuver during sewing
Solution Approach 1:
The patent employs an air table system that generates upward airflow through vents to counteract the weight of the heavy mattress topper during sewing operations. The air supply creates a cushion of air that supports the topper, allowing workers to maneuver and sew the heavy material without direct physical contact, effectively neutralizing the weight problem.
3Ease of manufacture
If traditional sewing table is used to sew mattress topper, then sewing can be performed, but multiple people are required to maneuver the heavy topper
Solution Approach 1:
The patent introduces an air table as an intermediary device between the worker and the mattress topper. Instead of workers directly manipulating the heavy topper on a traditional table, the air table serves as a mediator that supports and facilitates movement of the topper through airflow, enabling single-operator capability.
4Strength
If mattress topper is made bulky to provide adequate cushioning, then comfort is improved, but it appears out of place and creates aesthetic issues
Solution Approach 1:
The patent utilizes a side layer that extends down along the side of the mattress, creating a skirting effect that conceals the bulk of the topper while maintaining the cushioning layers. This flexible side extension allows the topper to provide adequate thickness for comfort while presenting a sleek, streamlined appearance that integrates with the mattress aesthetic.
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
The design extends the lifespan of the mattress topper by reducing stress on the seams and simplifies the sewing process by allowing the mattress topper to be lifted and maneuvered more easily, preventing bulging and improving aesthetics.
Implementation Method 1
an air supply connected to the bottom panel and at least substantially aligned with the at least one air intake hole, the at least one air supply configured to blow air into an air chamber of the air table through the at least one air intake hole

AI summary
A mattress topper for fitting to a mattress may include a lower layer, a side layer configured to extend down along a side of the mattress, and an upper layer overlaying the lower layer and at least partially disposed between the lower layer and the side layer. The mattress topper may also include a seam including threads and extending along peripheral edges of the lower layer and the upper layer and extending through the lower layer, upper layer, and side layer, the lower layer and side layer bearing the threads of the seam. An air table may include a top panel including a plurality of vents extending through the top panel. A method of making a mattress topper with an air table may include lifting the mattress topper with the air table while performing sewing procedures on the mattress topper.
