Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging processes face challenges in introducing moisture into flat fiber materials effectively for shaping and joining, as excessive moisture can compromise the mechanical stability of the materials, making transport and processing difficult.
Innovation Solution
A method involving the partial introduction of a defined amount of humidification medium into specific surface areas of flat fiber materials using a porous moisture transfer medium, allowing controlled moisture application to enhance deformability and joinability while maintaining overall stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If moisture is introduced into sheet fiber material to improve shaping and joining, then deformability and joinability are improved, but mechanical stability and transportability deteriorate
Solution Approach 1:
The patent applies local quality by introducing moisture only into specific defined areas of the sheet fiber material rather than uniformly across the entire surface. This selective moistening targets regions where deformability and joinability are needed while leaving other areas dry to maintain mechanical stability and transportability during processing.
Solution Approach 2:
The patent segments the sheet fiber material surface into defined areas that receive moisture treatment versus areas that remain dry. This segmentation allows different regions to have different moisture contents, enabling simultaneous improvement of formability in treated areas while maintaining structural integrity in untreated areas.
2Ease of manufacture
If moisture is introduced uniformly across the sheet fiber material, then shaping and joining processes are facilitated, but transport and conveying become more difficult
Solution Approach 1:
The patent implements local quality by applying moisture selectively to defined areas of the sheet fiber material using a steam applicator or similar device. This localized approach facilitates shaping and joining in the moistened regions while keeping the majority of the material dry, thereby maintaining ease of transport and conveying during the manufacturing process.
3Strength
If contact time for humidification is extended to improve shaping, then moisture penetration increases, but production efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-moistening specific areas of the sheet fiber material before the actual shaping operation. This preliminary moistening is performed quickly and locally, preparing the material for subsequent forming without requiring extended contact times, thus maintaining high production efficiency while achieving adequate shaping quality.
Solution Approach 2:
The patent segments the humidification process into targeted applications on defined areas rather than prolonged uniform treatment. This allows rapid moisture application to specific zones that will undergo shaping, eliminating the need for extended overall contact time and thereby preserving production efficiency.
