Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper materials struggle to achieve special tactile and fragrant effects while maintaining high printability and quality, as these effects often compromise other paper characteristics.
Innovation Solution
A paper material comprising a support base with a mixture of cellulose fibers and animal milk protein fibers, treated with an anti-dissolving agent and surface adhesive, allowing for a maximum 50% animal milk protein content by weight, which is processed to create a velvet-like, milk-scented finish and is printable with high quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If animal milk protein fibres are incorporated into paper material to create velvet-like texture and milk scent, then tactile and fragrant effects are improved, but printability and manufacturing complexity deteriorate
Solution Approach 1:
The patent applies parameter changes by controlling the animal milk protein fibre content within a specific range (1-50% by weight) and using surface treatment with adhesives to modify the paper surface properties. This allows the paper to achieve velvet-like texture and milk scent while maintaining printability through optimized parameter combinations.
Solution Approach 2:
The patent creates a composite paper material by combining animal milk protein fibres with conventional cellulose fibres, polymeric substances, and inorganic fillers. This composite structure enables the paper to simultaneously achieve special tactile and fragrant effects while maintaining good printability and strength properties.
2Adaptability or versatility
If animal milk protein fibres are used to achieve special effects, then product differentiation is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-treating the animal milk protein fibres with anti-dissolving agents before paper formation. This pre-treatment prevents fibre dissolution during the papermaking process, simplifying manufacturing while enabling the use of milk protein fibres for product differentiation.
Solution Approach 2:
The patent optimizes manufacturing parameters including fibre content (1-50% by weight), moisture content (8-15%), and surface adhesive application to balance product differentiation with manufacturing simplicity. These parameter controls enable conventional papermaking equipment to produce differentiated paper products.
