Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging materials made of fibers or waste paper boards struggle to provide an effective buffering impact, as they lack the necessary properties to absorb or mitigate external forces effectively.
Innovation Solution
A sheet-shaped web manufacturing process using a specific apparatus that fibers and a bonding material, where the fiber orientation direction is aligned to enhance the buffering capacity by distributing impact energy through fiber movement and bonding, similar to styrofoam, but with environmentally friendly materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If fiber-based packaging materials are used, then environmental sustainability is improved, but buffering effect against impact deteriorates
Solution Approach 1:
The patent changes the physical parameters of fiber-based materials by controlling fiber orientation, density, and structural configuration to achieve impact buffering properties while maintaining environmental sustainability. This resolves the contradiction by showing that fiber materials can be engineered to provide both eco-friendliness and protective buffering effects.
Solution Approach 2:
The invention creates composite structures using fiber materials with specific orientations and configurations, combining multiple fiber layers or types to achieve both environmental benefits and effective impact buffering. The composite approach allows the material to exhibit properties superior to individual fiber types alone.
2Ease of manufacture
If waste paper board is shaped by heating and pressurizing, then manufacturing capability is improved, but buffering effect against impact deteriorates
Solution Approach 1:
The patent optimizes manufacturing parameters such as heating temperature, pressurization pressure, and treatment time to achieve the desired balance between shaping capability and buffering effect. By carefully controlling these parameters, the material gains structural integrity for shaping while retaining impact absorption properties.
3Reliability
If fiber orientation is controlled to enhance buffering capacity, then impact absorption is improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the fiber material into oriented segments or layers with specific directional arrangements. This segmentation approach simplifies the manufacturing process by using standardized orientation patterns that can be achieved through conventional equipment, while still providing enhanced buffering capacity through the organized fiber structure.
