Unitary Double-Layer Trim Piece with Apertures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional trim piece assemblies, such as waistbands or underbands, require multiple pieces of material, increasing production costs, introducing structural weaknesses, and material waste, while also complicating assembly and quality control.
Innovation Solution
A double-layer trim piece is constructed from a unitary knit or woven textile, reducing assembly steps and material waste by folding a single textile along its longitudinal axis, with strategically placed apertures for moisture transport and heat transfer, and optional structural reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pieces of material are used to construct trim piece assemblies, then design flexibility and functionality can be improved, but production costs increase, assembly complexity increases, and structural weaknesses are introduced at attachment points
Solution Approach 1:
The patent combines multiple separate trim piece components into a single integrated trim piece constructed from one continuous piece of material. This merging eliminates the need for multiple attachment points and simplifies assembly while maintaining design flexibility through strategic material selection and construction methods for different zones of the trim piece.
Solution Approach 2:
The trim piece is divided into multiple zones with different material properties or constructions to provide functionality in specific areas. This segmentation allows different portions of the single-piece trim to serve different purposes (e.g., elastic zones, breathable zones, structural zones) without requiring separate components.
2Adaptability or versatility
If multiple pieces of material are assembled into trim pieces, then functional zones can be created, but the number of assembly steps increases production costs and introduces quality control issues
Solution Approach 1:
Multiple functional zones that would traditionally require separate material pieces are integrated into a single continuous material construction. This eliminates assembly steps and associated quality control issues while maintaining the ability to create different functional zones through material selection, knitting patterns, or weaving variations within the single piece.
Solution Approach 2:
Different zones of the trim piece utilize different material properties, constructions, or treatments to provide specific functions where needed. This allows functional differentiation without requiring multiple separate components, as each zone is optimized for its specific purpose while being part of the same integrated structure.
3Manufacturing precision
If multiple pieces of material are used to form trim pieces, then design requirements can be met, but material waste increases due to cutting to match patterns
Solution Approach 1:
The trim piece is constructed from one continuous piece of material, eliminating the need to cut and join multiple pieces to match patterns. This single-piece construction significantly reduces material waste while still allowing precise pattern matching and design requirements to be met through the material selection and construction methods used for different zones.
