Breathable Mesh Bag With Segmented Tear-Strip Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mesh packaging for horticultural products is difficult to open practically and control, leading to potential accidental opening during storage, distribution, and transportation, while maintaining tamper evidence and mechanical performance.
Innovation Solution
A breathable mesh bag with a flexible sheet applied outside the mesh casing, featuring a removable portion with tear lines that allows controlled access, ensuring the bag can be opened easily without compromising its integrity or tamper evidence, and is compatible with existing manufacturing methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mesh packaging is made with high resistance material to prevent accidental opening, then tamper evidence and mechanical performance are improved, but the difficulty of practical opening operation increases
Solution Approach 1:
The flexible sheet is segmented into a fixed portion and a removable portion through tear lines. The fixed portion maintains mechanical strength and tamper evidence by remaining attached to the mesh casing, while the removable portion can be easily torn off to provide practical access to the opening without compromising the overall structural integrity of the packaging.
Solution Approach 2:
Different portions of the flexible sheet have different functions: the fixed portion provides structural support and tamper evidence with high strength properties, while the removable portion is designed for easy removal to enable practical opening. This local differentiation resolves the contradiction between maintaining reliability and enabling ease of operation.
2Strength
If the mesh packaging is made with high resistance material, then mechanical performance is improved, but the ease of opening operation deteriorates
Solution Approach 1:
The flexible sheet is divided into fixed and removable portions. The fixed portion maintains mechanical strength and supports the mesh casing structure, while the removable portion can be easily torn off to provide practical access, thus resolving the contradiction between strength and ease of operation.
Solution Approach 2:
Different portions of the flexible sheet have different functions: the fixed portion provides structural support with high strength properties, while the removable portion is designed for easy removal to enable practical opening. This local differentiation resolves the contradiction between maintaining strength and enabling ease of operation.
3Ease of operation
If the flexible sheet is completely removed to provide access, then ease of operation is improved, but tamper evidence is compromised
Solution Approach 1:
The flexible sheet is segmented into fixed and removable portions. Only the removable portion is removed to provide access, while the fixed portion remains attached to the mesh casing, preserving tamper evidence. This segmentation allows ease of operation without compromising reliability.
Solution Approach 2:
Different portions of the flexible sheet have different functions: the fixed portion provides structural support and tamper evidence, while the removable portion is designed for easy removal to enable practical opening. This local differentiation resolves the contradiction between ease of operation and tamper evidence.
4Ease of operation
If the opening is made practical and easy to open, then ease of operation is improved, but accidental opening during storage and transportation increases
Solution Approach 1:
The flexible sheet is segmented into fixed and removable portions. The fixed portion remains securely attached to the mesh casing during storage and transportation, preventing accidental opening, while the removable portion can be easily detached when intentional opening is required. This segmentation resolves the contradiction between ease of operation and accidental opening prevention.
Solution Approach 2:
Different portions of the flexible sheet have different functions: the fixed portion provides structural support and prevents accidental opening, while the removable portion is designed for easy removal to enable practical opening. This local differentiation resolves the contradiction between ease of operation and accidental opening prevention.
