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

VSEngineering 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

Engineering Contradiction:
Improveproduction process simplicityVSAvoidwaste production
Core Design Contradiction:
Ease of manufactureVSLoss of substance

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Engineering Contradiction:
Improveproduction process simplicityVSAvoidmachine complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

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

Engineering Contradiction:
Improveproduction efficiencyVSAvoidmaterial waste
Core Design Contradiction:
ProductivityVSLoss of substance

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.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

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.

Inventive Principle:
Principle #35Parameter changes
