Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding boxes for light-sensitive materials allow excessive light penetration and may unintentionally open, compromising the protection of these materials.
Innovation Solution
A folding box design featuring a double wall structure with a light protection wall and guide elements that prevent accidental opening, combined with a latching mechanism to enhance light protection and mechanical integrity, while optimizing production efficiency by minimizing the extent of the light protection panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a simple single-wall folding box is used, then manufacturing is simple and material usage is low, but light protection is insufficient and mechanical integrity is weak
Solution Approach 1:
The box wall is segmented into multiple panels (first, second, third, fourth panels) separated by fold lines, creating a double-wall structure that provides both light protection and mechanical integrity while maintaining foldability
Solution Approach 2:
The box transitions from a flat two-dimensional layout to a three-dimensional folded structure with vertical walls, adding spatial dimensionality that enables light blocking while preserving the flat packaging state for efficient storage and transport
2Ease of operation
If the box is designed to be easily openable, then ease of operation is improved, but the box may unintentionally open due to mechanical stress
Solution Approach 1:
The tear line is pre-positioned to extend from the first panel through the second panel to the third panel, abutting the central horizontal fold line in the fourth panel, enabling controlled opening while the guide elements are pre-configured to prevent unintended opening
Solution Approach 2:
Guide elements are introduced as intermediary components between the lid and box body, providing a latching function that prevents accidental opening while allowing intentional opening through the tear line mechanism
3Object-affected harmful factors
If the light protection panel extends to the lower horizontal fold line, then light protection is maximized, but material usage increases
Solution Approach 1:
The sixth panel extends partially beyond the horizontal tear line to provide sufficient light protection for the contents, avoiding the need to extend to the lower horizontal fold line and thus optimizing material usage while maintaining adequate protection
4Reliability
If guide elements are added to prevent accidental opening, then reliability is improved, but device complexity increases
Solution Approach 1:
The guide elements serve multiple functions: they provide the latching function to prevent accidental opening, guide the lid during opening and closing movements, and work in conjunction with the tear line system, reducing the need for separate components
