Flexible Liquid Dispenser with Fastening Tab for Tree Trunk Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispensing devices for trees, such as those used in arboriculture and viticulture, require time-consuming handling operations due to the need for straps and fastening mechanisms, which are costly and inefficient for mass production and quick deployment.
Innovation Solution
A flexible container with a fastening tab that can be secured to a tree trunk using a staple or adhesive, reducing the need for complex fastening systems and allowing for quicker installation and removal, while also being made from less material to lower production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid container with strap fastening system is used, then the device provides stable support and reliable fastening, but the handling operations become time-consuming and costly
Solution Approach 1:
The invention extracts and eliminates the complex strap fastening system from the device. Instead of using a rigid container with strap, the patent uses a flexible container that can be directly fastened to the tree trunk with simple fastening elements, removing the intermediate strap component and simplifying the overall fastening operation.
Solution Approach 2:
The invention changes the material parameter of the container from rigid to flexible. This parameter change allows the container to be made from lighter, less expensive material while enabling direct fastening to the tree trunk without complex strap systems, thereby reducing installation time while maintaining reliability.
2Stability of the object's composition
If a rigid container is used, then the device provides structural stability, but the manufacturing cost increases due to material usage
Solution Approach 1:
The invention changes the material parameter of the container from rigid to flexible, reducing the amount of material required while maintaining sufficient structural stability for the application. This parameter change directly reduces manufacturing cost while the flexible nature allows the container to adapt to the tree trunk shape.
Solution Approach 2:
The invention employs a flexible container made from thin film or flexible material instead of rigid container. This approach reduces material usage and manufacturing cost while the flexibility allows the container to maintain structural integrity when fastened to the tree trunk, eliminating the need for expensive rigid materials.
3Reliability
If a complex fastening system with strap is used, then the device ensures secure attachment, but the ease of operation deteriorates
Solution Approach 1:
The invention extracts and removes the complex strap fastening system from the device. The flexible container is designed to be directly fastened to the tree trunk using simple fastening elements, eliminating the need for separate straps and complex fastening mechanisms, thereby significantly improving ease of operation while maintaining attachment security.
Solution Approach 2:
The invention segments the fastening function from the container body, allowing the flexible container to be independently fastened to the tree trunk using simple fastening elements. This segmentation simplifies the fastening operation while maintaining secure attachment, as the fastening elements can be independently applied without complex strap mechanisms.
