Multilayered Threshold Co-Extrusion Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing doorway thresholds are limited in color options due to the high cost of certain pigments, making it economically unfeasible to offer a variety of finishes, textures, and colors, while designers seek cost-effective solutions for aesthetically diverse options.
Innovation Solution
A multilayered, multicolored threshold is created using a co-extrusion process with a low-cost main body portion and a top layer of customized color and texture, allowing for a desired aesthetic appearance without constructing the entire threshold from the top layer material, featuring a central groove and longitudinal channels for various flooring transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire threshold is constructed from expensive pigmented material to achieve desired aesthetic appearance, then color variety and finish options are improved, but production cost increases significantly
Solution Approach 1:
The threshold is divided into two distinct segments: a main body portion made from low-cost polymer and a top layer made from expensive pigmented polymer. This segmentation allows each part to serve its specific function - the main body provides structural integrity while the top layer provides aesthetic appearance, thereby reducing overall production cost while maintaining color variety options.
Solution Approach 2:
The expensive pigmented material is applied only to the top layer where aesthetic appearance is required, rather than throughout the entire threshold. This local quality approach ensures that pigment is used only where visually necessary, minimizing material cost while achieving the desired color variety and finish options for different design applications.
2Ease of manufacture
If low-cost polymer is used for the entire threshold to reduce production cost, then production cost decreases, but color variety and aesthetic options are limited
Solution Approach 1:
By segmenting the threshold into a low-cost main body and an expensive pigmented top layer, the design enables cost-effective production while preserving the ability to offer various colors and finishes through the top layer. This segmentation allows the expensive aesthetic portion to be optimized for visual impact rather than structural requirements.
Solution Approach 2:
The threshold employs a composite structure combining two different polymer materials with distinct properties. The main body uses low-cost polymer for structural efficiency, while the top layer uses expensive pigmented polymer for aesthetic versatility. This composite approach allows the product to achieve both cost-effectiveness and color variety simultaneously.
3Device complexity
If uniform material is used throughout the threshold, then manufacturing process is simplified, but aesthetic diversity and design options are reduced
Solution Approach 1:
The threshold is segmented into two functional zones with different material requirements. The main body portion uses uniform low-cost polymer for simplified manufacturing, while the top layer uses expensive pigmented polymer for aesthetic diversity. This segmentation allows each section to be optimized independently, balancing manufacturing simplicity with design versatility.
Solution Approach 2:
Different material qualities are applied to different portions of the threshold based on functional requirements. The main body has uniform material properties optimized for structural integrity and cost-effective production, while the top layer has specialized pigmented material properties optimized for aesthetic diversity and design options.
