Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insect suction machines for plants are inefficient due to obstruction by leaves and other debris, and are not effective against diverse insect sizes, leading to incomplete disinfestation and increased costs.
Innovation Solution
A machine with a design that includes adjustable crushing sheets and a containment body structure to automatically remove foliage and intercept insects, ensuring optimal airflow and effective insect removal without obstructing the crushing mechanism, capable of handling various insect sizes and types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a crushing grid with parallel blades is used to kill suctioned insects, then insect mortality increases, but the crushing grid becomes obstructed by leaves and debris during operation
Solution Approach 1:
The crushing grid is divided into multiple segments that can rotate independently around a central axis. This segmentation allows debris to pass through the gaps between segments while insects are crushed by the rotating blades, resolving the obstruction problem while maintaining insect mortality effectiveness
Solution Approach 2:
The crushing grid transitions from a static structure to a dynamic rotating mechanism. The rotation of the segmented blades creates continuous motion that prevents debris accumulation and allows automatic clearing of obstructions, while the rotating blades maintain effective insect crushing through centrifugal force and blade impact
2Reliability
If selective phytosanitary products are used to target specific insect species, then effectiveness against target insects increases, but the number of products required increases leading to higher costs
Solution Approach 1:
The patent replaces chemical phytosanitary products with a mechanical suction and crushing system. The suction unit with rotatable mouth and the rotating crushing grid work together to physically remove and kill insects, eliminating the need for multiple selective chemical products and reducing overall product quantity required
