Reinforced Pocket Device Tear Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pocket devices, such as dividers or folders, experience undue stress and tearing due to repeated use, leading to durability issues.
Innovation Solution
The implementation of reinforcing materials strategically positioned on the edges of pocket panels to enhance tear resistance and durability, specifically by applying reinforcing strips that are spaced apart from the edges to prevent adhesive issues and ensure accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcing material is positioned directly on the edge of the pocket panel, then tear resistance is improved, but adhesive application becomes problematic and accessibility is reduced
Solution Approach 1:
The reinforcing material is positioned at a specific location on the pocket panel - spaced apart from the edge by a distance between 0.25 to 2 inches. This local positioning provides tear resistance near the edge without the material directly contacting the edge, allowing adhesive to be applied to the edge area without interference while still providing reinforcement where tearing is most likely to occur.
2Strength
If reinforcing material is placed close to the pocket edge, then tear resistance is improved, but accessibility to the pocket mouth is reduced
Solution Approach 1:
The reinforcing material is strategically positioned at a distance from the edge (0.25 to 2 inches) to provide local reinforcement in the high-stress area near the pocket mouth while maintaining sufficient clearance to not interfere with the insertion and removal of items from the pocket. This creates an optimal balance between structural reinforcement and functional accessibility.
