Solution Overview
Problem
Existing plant extraction methods are inefficient and cumbersome for removing unwanted plants, particularly in outdoor settings where manual removal is labor-intensive and often ineffective.
Innovation Solution
A wearable plant extraction device comprising a housing with a flexible hose, a motor-driven shaft with a rotating blade and propeller, which cuts and collects plants through a tube system, allowing for efficient removal and collection of plant material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual plant removal is used, then no special equipment is needed, but labor intensity is high and extraction efficiency is low
Solution Approach 1:
The patent replaces manual mechanical removal with an automated mechanical system comprising an engine, cutting blade, and collection mechanism. The engine-driven blade automatically cuts plants while the suction system collects debris, eliminating the need for manual bending, pulling, and bagging operations.
Solution Approach 2:
The device performs multiple functions automatically: the cutting blade self-cuts the plant material, the propeller self-generates suction to collect debris, and the system self-transports waste to the collection bag without requiring manual intervention at each step.
2Speed
If traditional extraction tools are used, then device complexity is low, but extraction speed is slow and labor-consuming
Solution Approach 1:
The patent combines multiple extraction functions into a single integrated device: the engine powers both the cutting blade and the propeller, the tube serves as both structural support and waste conduit, and the housing contains both the engine and collection bag, achieving high-speed extraction while consolidating complexity into one unit.
Solution Approach 2:
The device performs multiple functions simultaneously: the engine provides power for both cutting and suction, the shaft transmits power to both the blade and propeller, and the tube system handles both structural support and waste transport, making each component multi-functional to reduce overall system complexity.
3Loss of time
If manual plant removal is used, then equipment requirements are minimal, but time consumption is high
Solution Approach 1:
The engine runs continuously to simultaneously drive the cutting blade and propeller, creating a continuous extraction process where plants are cut, collected, and stored without interruption, eliminating the sequential steps and idle time associated with manual removal methods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enables efficient and convenient removal of unwanted plants by cutting and collecting them with minimal manual effort, reducing labor and improving the speed of the extraction process.
Implementation Method 1
A propeller is coupled to the shaft. The propeller is rotated by the shaft so suction is provided from the second end of the tube into the tube.

AI summary
A plant extraction assembly includes a housing that may be worn on a user's back. A flexible hose is fluidly coupled to and extends from the housing. A tube is fluidly coupled to a second end of the hose. A motor is coupled to a first end of the tube. A shaft is positioned within the tube. The shaft is rotationally coupled to the motor. A blade is coupled to the shaft. The blade is positioned at a second end of the tube so the blade may contact a plant positioned adjacent to the second end of the tube. A propeller is coupled to the shaft. The propeller provides from the second end of the tube into the tube. The propeller may urge pieces of the plant cut by the blade upwardly through the tube and the hose into the housing.
