Shaped Baffle Construction for Tailored Insulation Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-layered constructions with rectangular baffles lack strength and design flexibility, limiting the ability to customize insulation distribution and causing misshapen products when trying to vary down material placement.
Innovation Solution
Shaped baffles with non-rectangular cross-sections, such as triangular, curved, or tapered edges, are integrated between fabric layers to form complex chambers, enhancing structural stability and allowing for tailored insulation distribution without excess material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional rectangular baffles are used, then ease of manufacture is improved, but structural strength and design flexibility deteriorate
Solution Approach 1:
The patent applies curvature by transitioning from flat rectangular baffles to baffles with curved surfaces. The curved baffle profiles create three-dimensional structural forms that inherently provide greater strength and rigidity while maintaining manufacturability through standard fabrication processes.
Solution Approach 2:
The invention moves from two-dimensional rectangular baffles to three-dimensional curved baffles. This dimensional transition allows the baffles to provide structural strength in multiple directions simultaneously, creating more robust constructions without significantly complicating manufacturing.
2Ease of manufacture
If conventional rectangular baffles are used, then ease of manufacture is improved, but design flexibility deteriorates
Solution Approach 1:
The curved baffles enable local variation in chamber dimensions and shapes. Different sections of the construction can have baffles with different curvature radii, allowing customization of insulation properties, material distribution, and thermal performance in specific areas while maintaining overall manufacturing simplicity.
3Device complexity
If single thickness baffles are used, then manufacturing simplicity is improved, but functional versatility deteriorates
Solution Approach 1:
The patent implements variable thickness baffles where the baffle thickness changes continuously or in steps along its length. This allows different regions to have optimized thickness for their specific functional requirements, such as providing greater insulation in cold zones or allowing more material space in other areas, all from a single integrated component.
4Quantity of substance
If down material is unevenly distributed, then insulation performance is improved, but product shape deteriorates
Solution Approach 1:
The curved baffle surfaces naturally guide and contain down material distribution. The varying curvature creates chambers with optimized volumes that hold specific quantities of down material, ensuring even distribution patterns that maintain the desired product shape and profile.

AI summary
A multi-layered construction includes a first fabric, a second fabric, and a baffle disposed between the first and second fabrics. The baffle is attached to the first and second fabrics so as to form a plurality of triangular-shaped chambers between the first and second fabrics. In other words, the baffle forms a zigzag-like pattern between the first and second fabrics. Another multi-layered construction also includes a first fabric, a second fabric, and a baffle disposed between the first and second fabrics. This baffle has a non-rectangular cross-section. More particularly, in certain examples, the baffle may have at least one curved edge and/or at least one tapered edge. In other examples, the baffle may have a vase-like cross-section having at least two curved edges.
