Sheet Material Container With Soft, Impact-Resistant Film Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet member containers lack a soft texture and adequate flexibility, which affects user grip and structural strength, particularly when subjected to impact.
Innovation Solution
A sheet member container design featuring a main-body forming sheet member with non-attached regions between inner and outer film layers, allowing for a softer texture and enhanced flexibility, and a peripheral edge sealing portion that maintains structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If film layers are fully attached to form a rigid container structure, then structural strength is improved, but flexibility and soft texture deteriorate
Solution Approach 1:
The container body is divided into multiple regions with different attachment states: fully attached regions (first attached region) provide structural strength, while partially unattached regions (second attached region) provide flexibility. This segmentation allows different parts of the same container to have different mechanical properties.
Solution Approach 2:
Different regions of the container body are given different attachment characteristics: the first attached region has complete film layer attachment for rigidity, while the second attached region has partial attachment for softness. This local differentiation resolves the contradiction between overall strength and local flexibility.
2Stability of the object's composition
If film layers are fully attached to maintain container shape, then structural integrity is improved, but impact resistance deteriorates
Solution Approach 1:
The second attached region with partially unattached film layers acts as a pre-designed cushioning zone that absorbs impact energy before it reaches the fully attached regions. This beforehand cushioning protects the structural integrity of the container during impact events.
Solution Approach 2:
The container has localized soft regions (second attached region) that specifically address impact resistance, while maintaining hard regions (first attached region) for structural integrity. This local quality differentiation allows the container to resist impact without compromising overall structural stability.
3Manufacturing precision
If a rigid container structure is used, then manufacturing precision is improved, but ease of handling deteriorates
Solution Approach 1:
The container is segmented into precision-formed regions (first attached region with complete attachment) and flexible regions (second attached region with partial attachment). This segmentation allows the precision requirements to be localized to specific areas while other areas provide handling flexibility.
Solution Approach 2:
Different attachment states are applied to different locations: the first attached region maintains precise geometric accuracy for manufacturing, while the second attached region provides softness for easy handling. This local quality approach resolves the contradiction between precision and ease of operation.
