Skimmer Net Inside-Out Inversion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional skimmer nets require direct hand contact for emptying, posing safety and sanitation risks when dealing with contaminated debris like dead animals and bacteria-infested organic matter.
Innovation Solution
A skimmer net apparatus with a handle, net-bottom-rod, movable frame, and linkage mechanism that allows the net to be rotated inside out without direct hand contact, using a slider to translate along the handle and pivot the movable frame, enabling the net to be emptied without manual handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional skimmer nets are used, then the net can capture debris effectively, but direct hand contact is required for emptying which poses safety and sanitation risks
Solution Approach 1:
The patent applies inversion by turning the net inside out through a mechanical linkage system. The slider moves along the handle to rotate the movable frame, which inverts the net configuration. This allows debris to be emptied without direct hand contact, resolving the contradiction between safety and ease of operation.
Solution Approach 2:
The patent introduces a linkage mechanism as an intermediary between the user's hand operation and the net emptying process. The slider and linkage system mediate the action, allowing the user to empty the net by moving the slider rather than by direct hand contact with the debris, thus eliminating exposure to hazardous materials while maintaining ease of operation.
2Object-affected harmful factors
If the net is designed with a movable frame and linkage mechanism, then emptying can be done without hand contact, but the device complexity increases
Solution Approach 1:
The patent segments the net structure into a fixed frame and a movable frame that can rotate independently. The movable frame is connected through a linkage mechanism to a slider on the handle. This segmentation allows the net to be inverted for emptying while keeping the overall device relatively simple and manageable.
3Ease of operation
If the net structure is simplified for easy operation, then ease of operation improves, but the ability to rotate and empty the net without hand contact is compromised
Solution Approach 1:
The patent employs dynamics by making the frame movable rather than fixed. The movable frame can rotate about an axis perpendicular to the handle axis, enabling the net to be inverted for emptying. This dynamic capability is controlled through the slider-linkage system, providing ease of operation while achieving the safety benefit of no hand contact.

AI summary
A skimmer apparatus has a handle, a net-bottom-rod at a right angle to the handle, offset from the axis of the handle and joined rigidly to an extension of the handle, a movable frame rotatable about an axis at a right angle to the axis of the handle, a slider translatable on the handle, a linkage mechanism joined to the movable frame and to the slider rotating the movable frame about the axis at a right angle to the axis of the handle, and net material joined to the movable frame and to the net-bottom-rod. Moving the slider away from the net employs the linkage mechanism to rotate the movable frame past the net-bottom-rod, such that the net is turned inside out, facilitating divesting material captured in the net.
