Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing materials for packaging agricultural products in automated machines are complex to produce, costly, and prone to bale breakage due to inadequate closure and recyclability issues, leading to material loss and environmental impact.
Innovation Solution
A single, continuous plastic film with detachable packaging portions featuring a permanent adhesive and a 'V' configuration for secure closure, combined with a rupture line and signaling means for efficient separation and bale formation, enhancing resistance to weather and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex multi-segment plastic canvas materials are used for packaging agricultural products, then bale closure can be achieved, but production complexity and cost increase significantly
Solution Approach 1:
The continuous plastic film is divided into detachable segments separated by rupture lines. Each segment can be independently handled and attached to bales, while the continuous nature of the film simplifies production compared to traditional multi-segment canvases. The segmentation allows for easier material handling and bale closure without requiring complex assembly processes.
Solution Approach 2:
The patent merges the functions of multiple separate plastic canvas segments into a single continuous film structure. This continuous film maintains the bale closure reliability of multi-segment systems while eliminating the production complexity associated with assembling and connecting individual segments, thereby reducing manufacturing costs and simplifying the production process.
2Object-affected harmful factors
If traditional plastic canvas materials are used for packaging, then bale protection is provided, but material loss and environmental impact increase due to recyclability issues
Solution Approach 1:
The continuous plastic film structure enables easier recovery and recycling of the packaging material. The film can be collected in its continuous form and processed for recycling, reducing material loss compared to traditional segmented canvases that are difficult to recover. This approach maintains weather protection functionality while addressing environmental concerns through improved material recovery.
3Ease of manufacture
If inadequate closure materials are used, then production costs are reduced, but bale integrity is compromised leading to material loss
Solution Approach 1:
The patent changes the physical and chemical parameters of the plastic film to optimize both cost and performance. By adjusting the film's tensile strength, flexibility, and attachment characteristics, the material provides adequate closure for maintaining bale integrity while remaining cost-effective to produce. The continuous film structure with controlled rupture lines achieves this balance without requiring expensive multi-segment systems.
