Plant Container Connecting Slit Formation Using Sharp Cutting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for forming connecting slits in plant containers, such as pots or trays, are inefficient and costly due to the use of punching machines, resulting in waste production and complex production processes.
Innovation Solution
A method using a sharp cutting element to create a sine-shaped or corrugated connecting slit without width in the plant container's rim, eliminating waste and allowing for simpler, cost-effective production, with the slit being formed in a recessed part to enhance user-friendliness and security of label attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a punching machine is used to form a connecting slit, then the slit can be formed in the plant container, but waste is produced and the production process becomes complex
Solution Approach 1:
The invention extracts only the necessary cutting function from the punching machine, separating the slit formation process from the rest of the punching mechanism. This allows the connecting slit to be formed without producing waste cut-out parts, as only the minimal necessary material removal is performed to create the slit opening.
Solution Approach 2:
The invention replaces the conventional punching machine with a simpler cutting element that can be integrated into existing plant container production lines. This substitution eliminates the need for complex punching mechanisms and waste disposal systems while achieving the same connecting slit formation.
2Ease of manufacture
If a punching machine is used to form a connecting slit, then the slit can be formed in the plant container, but the device complexity increases
Solution Approach 1:
The invention extracts only the essential cutting functionality from the punching machine, removing the complex punching mechanism entirely. The simplified cutting element can be easily integrated into existing plant container production equipment without requiring complex machine modifications.
Solution Approach 2:
The invention employs a simple, inexpensive cutting element that can be easily replaced if needed, rather than investing in complex, expensive punching machinery. This approach reduces device complexity and maintenance requirements while achieving the same manufacturing function.
3Productivity
If a connecting slit is formed with width, then the slit can be formed in the plant container, but production costs increase due to waste
Solution Approach 1:
The invention converts the potentially harmful effect of material removal into a beneficial process by using a cutting element that creates the connecting slit with minimal to no waste. The cutting action is optimized to remove only the absolute minimum material necessary, transforming what would normally be waste into a negligible byproduct.
Solution Approach 2:
The invention changes the geometric parameters of the connecting slit formation process, transitioning from a punched slit with inherent width and waste to a cut slit with minimal material removal. This parameter change in the formation method eliminates waste while maintaining the functional integrity of the connecting slit.
