Baffled Insulating Panel with Nested Layers to Reduce Particle Escape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insulating particles in blankets and garments, such as feathers or synthetic fibers, tend to escape or protrude through stitch openings during laundering, compromising the aesthetic appeal and insulation efficiency.
Innovation Solution
The use of baffled insulating panels with multiple layers of insulating particles captured between walls, where a second insulating layer spans across the top of the walls, concealing them and reducing the visibility of stitching, thereby minimizing particle escape and protrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulating particles are contained in a panel with stitch openings, then the panel provides insulation, but insulating particles escape or protrude through the stitch openings during laundering
Solution Approach 1:
The panel is segmented into multiple compartments by vertical walls that divide the insulating particle layer into separate sections. This segmentation prevents particle migration between compartments and reduces protrusion through stitch openings, as each compartment is independently contained.
Solution Approach 2:
A second insulating particle layer is nested over the top of the vertical walls, creating a nested structure where the outer layer conceals the wall structures and associated stitching. This nesting approach hides the segmentation features while maintaining particle containment benefits.
2Reliability
If vertical walls are added to create compartments, then particle escape is reduced, but the visibility of stitching and walls increases
Solution Approach 1:
The second insulating particle layer is placed over the vertical walls to nest within the overall panel structure, concealing the wall features and associated stitching from external view while maintaining the compartmentalization benefits for particle retention.
Solution Approach 2:
The second insulating particle layer uses material with similar optical properties (color, texture, reflectivity) to the first layer, making the wall structures and stitching invisible when viewed from the exterior, as the outer layer matches the overall panel appearance.
3Shape
If multiple layers of insulating particles are used, then aesthetic appeal is maintained, but the complexity of panel construction increases
Solution Approach 1:
The second insulating particle layer serves multiple functions simultaneously: it conceals the vertical walls and stitching from view, provides additional insulation, and maintains the aesthetic appearance of the panel. This multi-functionality reduces the need for separate aesthetic components.
Solution Approach 2:
The aesthetic concealment function and insulation function are merged into a single component (the second insulating particle layer), eliminating the need for separate aesthetic coverings and simplifying the overall panel construction despite the added layer.

AI summary
A baffled insulating garment/blanket panel may include a first layer, a second layer, an insulating particle layer and a third layer. The second layer may have folds forming trough-shaped walls comprising a first wall, a second wall and a third wall, each of which is secured to the first wall. The insulating particle layer may include a first portion between the first wall and the second wall and sandwiched between the first layer and the second layer and a second portion between the second wall and the third wall and sandwiched between the first layer and the second layer. The third layer may include folds forming consecutive trough-shaped walls comprising a fourth wall secured within the first wall and a fifth wall secured within the third wall, wherein portions of the third layer between the fourth wall and the fifth wall span across a top of the second wall.
