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

VSEngineering 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

Engineering Contradiction:
Improvetactile and fragrant effectsVSAvoidprintability
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

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.

Inventive Principle:
Principle #35Parameter changes

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.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If animal milk protein fibres are used to achieve special effects, then product differentiation is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveproduct differentiationVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #35Parameter changes
