Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pine needles often become impaled in patio screens, making them difficult to remove due to their location and the weight limitations of the screen structure, leading to accumulation and potential mold and debris issues.
Innovation Solution
A patio screen shaver with a blade and handle adapter system that allows the blade to adjust angle and be secured for cutting impaled pine needles, featuring a blade mount with fasteners and a geared mechanism for easy operation, enabling safe and efficient removal without damaging the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a person climbs on top of the patio screen to remove pine needles, then the pine needles can be removed from the exterior surface, but the screen structure cannot support the weight of a person
Solution Approach 1:
The patent introduces a long-handled blade tool as an intermediary device that allows the user to cut pine needles from the exterior surface without directly contacting or climbing on the screen structure. The blade extends through the screen from the interior side, enabling cutting action on the exterior side while the user remains safely inside the screened area.
2Reliability
If impaled pine needles are left on the patio screen surface, then the screen structure remains undisturbed, but water accumulates and mold forms
Solution Approach 1:
The patent enables preliminary cutting of pine needles at their base before they can accumulate and cause problems. By cutting the needles close to the screen surface from the interior side, the procedure prevents subsequent water accumulation and mold formation without requiring removal of the needles themselves, thus maintaining screen integrity while eliminating harmful factors.
3Adaptability or versatility
If the blade angle is fixed, then the structure is simpler, but the blade cannot adapt to different cutting positions on the screen
Solution Approach 1:
The patent implements a dynamic angle adjustment mechanism in the handle adapter that allows the blade to be positioned at various angles relative to the handle. The adapter includes a slot and pivot point system that enables the blade to rotate and lock at different angles, providing adaptability for cutting pine needles at various locations and orientations on the screen.

AI summary
The present invention relates to a patio screen shaver for cutting pine needles that are impaled in a patio screen. The patio screen shaver includes a blade, a handle adapter, a handle, and a blade mount. The blade is secured in the blade mount and positioned to slide along the surface of the patio screen during use. The handle adapter interconnects with the blade mount adapter and has a geared ring. A handle interconnects with the handle adapter, and a button with a geared end engages the geared ring securing the handle and the handle adapter together in a movable manner. A user can press the button, allowing the handle adapter to rotate, changing the angle of the blade with respect to the handle. Releasing the button interlocks the geared end and the geared ring setting the angle of the blade for use by the user.
