Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If crude oil-based materials are used in textile production, then high performance and durability are achieved, but environmental harm and climate change contribution increase
Solution Approach 1:
The patent changes the fundamental parameter of material composition from crude oil-based polymers to regenerative cellulosic fibers (viscose, lyocell, modal) and bio-based coatings. This parameter change maintains performance requirements while eliminating the harmful factor of petroleum dependency and associated environmental damage.
Solution Approach 2:
The patent creates composite textile materials by combining regenerative cellulosic fiber backings with bio-based coating layers (water-based polyurethane, water-based acrylics, biobased polymers). This composite structure achieves the durability and performance of traditional synthetic materials while using renewable, biodegradable components throughout.
2Reliability
If synthetic polymeric materials are used, then product performance is maintained, but sustainability and biodegradability are compromised
Solution Approach 1:
The patent fundamentally changes the material composition parameters from non-biodegradable synthetic polymers to biodegradable regenerative cellulosic fibers and bio-based coatings. This enables the textile material to maintain performance while achieving sustainability and biodegradability at end of life.
Solution Approach 2:
The patent converts the traditional harm of non-biodegradable synthetic materials into benefit by using regenerative cellulosic fibers that are naturally biodegradable and can return to the environment harmlessly, turning the stability issue into a sustainability advantage.
3Object-affected harmful factors
If regenerative cellulosic materials are used, then sustainability and biodegradability are improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the textile material into distinct functional layers: a regenerative cellulosic fiber backing material and separate bio-based coating layers. This segmentation allows each layer to be optimized independently and applied through standard coating equipment, managing manufacturing complexity while achieving sustainability goals.
Solution Approach 2:
The patent uses water-based coatings that can serve multiple functions (adhesion, durability, coloration) and can be applied to various types of regenerative cellulosic backings (viscose, lyocell, modal), creating a universal manufacturing approach that reduces complexity across different product variations.
4Reliability
If multiple coating layers are applied, then performance properties are enhanced, but production time and processing steps increase
Solution Approach 1:
The patent combines multiple coating layers (water-based polyurethane, water-based acrylics, biobased polymers) into an integrated multi-layer structure that is applied and cured in a coordinated manufacturing process. This merging approach enhances performance properties while managing production time through efficient process integration.
