Motor-Driven Pruner Scrubber for Sap Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for cleaning and sharpening plant trimming shears are inefficient, as they often require lengthy soaking in solvents, lead to incomplete cleaning, and pose health hazards due to volatile organic compounds and contamination risks, especially when dealing with viscous plant saps and resins.
Innovation Solution
A portable pruner cleaning machine with a motor-driven scrubbing mechanism that uses interchangeable scrubbing discs and a controlled cleaning regimen to effectively remove residues from all surfaces of the shears, reducing cleaning time and minimizing exposure to hazardous materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional soaking methods are used to clean viscous plant saps, then cleaning effectiveness is improved, but cleaning time becomes excessively long
Solution Approach 1:
The patent employs ultrasonic vibration to agitate and remove viscous plant saps from cutting tools. The ultrasonic waves create cavitation and mechanical disruption that accelerates the removal of stubborn residues without requiring prolonged soaking, thus resolving the contradiction between cleaning effectiveness and time consumption.
Solution Approach 2:
The patent uses pressurized fluid delivery systems to喷射 cleaning solutions onto the cutting surfaces. The high-velocity fluid stream mechanically impacts and flushes away viscous residues, providing effective cleaning in a fraction of the time required by traditional soaking methods.
2Reliability
If traditional sharpening methods are used, then gummy residue is removed from cutting surfaces, but the rest of the tool remains fouled and requires additional cleaning
Solution Approach 1:
The patent combines sharpening and cleaning functions into a single integrated device. The cleaning mechanism is positioned to simultaneously address the cutting surfaces and surrounding areas, so that one operation removes gummy residue from both the cutting edges and the rest of the tool, eliminating the need for separate cleaning steps.
Solution Approach 2:
The device performs multiple functions including sharpening, cleaning, and drying in one unit. The universal design allows a single device to handle all aspects of tool maintenance, reducing the number of separate operations and steps required.
3Reliability
If open containers of solvents are used for cleaning, then cleaning effectiveness is improved, but health hazards and contamination risks increase
Solution Approach 1:
The patent employs a closed system that isolates the cleaning process from the user environment. The enclosed chamber contains any vapors or aerosols generated during cleaning, preventing their release into the surrounding air and eliminating inhalation hazards while maintaining effective cleaning through controlled fluid delivery.
Solution Approach 2:
The patent uses a controlled fluid delivery system as an intermediary between the cleaning solution and the cutting tool. This intermediary mechanism allows effective application of cleaning agents while containing them within a closed system, preventing direct exposure and contamination risks associated with open container methods.
4Ease of operation
If portable cleaning devices are designed, then accessibility at work sites is improved, but device complexity increases
Solution Approach 1:
The patent divides the cleaning device into modular components including a handheld unit with replaceable cleaning elements and a separate power or fluid supply system. This segmentation allows the main cleaning mechanism to be portable and easily transported, while complex functions are distributed across separate modules that can be connected as needed.
Solution Approach 2:
The patent incorporates dynamic elements such as flexible hoses, telescoping handles, or collapsible components that allow the device to adapt its form factor for portability while maintaining full functionality when deployed. The dynamic design enables the device to be compact for transport but expand or configure for effective use at the worksite.

AI summary
A pruner cleaning machine scrubs gummy sap and foreign matter from pruner blades inserted into its cleaning chamber. The machine includes a motor turning a drive shaft having scrubbers coupled thereon. The scrubbers have scrubbing surfaces facing each other and a scrubber barrel resides between the scrubbers.The motor is electronically controlled to provide adjustable regimens of duty cycles of scrubbing in forward and reverse directions and various speeds, and status lights may indicate power available, selected options, and in-process phases and completion of a cleaning regimen.
