Pivotable Blade Mechanism for Plant Trimmers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plant trimming devices have labor-intensive and time-consuming cleaning and maintenance processes due to fixed blade mechanisms that require tools for adjustment and removal, making it difficult to access and fine-tune the cutting blades.
Innovation Solution
A pivotable blade mechanism with hand-operated adjusting, unlocking, and locking means allows the blade bar to be easily connected and disconnected from the plant trimming device, enabling tool-free adjustment and cleaning by sliding or pivoting through pivot holes, using a clamp or bungee cord-like mechanism for secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed blade mechanism is used, then the blade is securely positioned, but cleaning and maintenance become labor-intensive and time-consuming
Solution Approach 1:
The blade mechanism transitions from a fixed position to a movable one, allowing it to slide between engaged and disengaged positions. This dynamic capability enables easy removal for cleaning while maintaining secure positioning during operation through the locking mechanism.
Solution Approach 2:
The blade mechanism is separated from the main device structure, allowing independent removal and cleaning. The blade can be detached without dismantling the entire plant trimming device, reducing maintenance complexity and time.
2Manufacturing precision
If a fixed blade mechanism requires tools for adjustment, then precise positioning is achieved, but the adjustment process becomes time-consuming
Solution Approach 1:
The blade mechanism incorporates a self-adjusting feature where the blade can be manually positioned and locked without requiring external tools. The user can directly manipulate the blade to achieve proper contact with the cutting reel and secure it using the integrated locking mechanism.
Solution Approach 2:
The adjustment mechanism allows dynamic repositioning of the blade during operation. The blade can be moved to different positions and locked in place, enabling quick fine-tuning of the cutting contact without tool intervention.
3Stability of the object's composition
If the blade mechanism is fixed to end walls, then structural stability is maintained, but access for cleaning becomes difficult
Solution Approach 1:
The blade mechanism is designed as a separate, detachable component that can be independently removed from the device. This segmentation allows the blade to be accessed and cleaned without disturbing the overall structural integrity of the plant trimming device.
Solution Approach 2:
The blade mechanism can transition between a secured position (maintaining structural stability) and a removed position (enabling easy cleaning). The movable design allows users to access the blade for cleaning by simply sliding it to a disengaged position or removing it entirely.

AI summary
A plant material trimming device includes two end walls supporting a rotatable perforated tumbler, a rotatable reel with helical blades, and a blade mechanism pivotably connected to the end walls of the device. The blade mechanism includes: (i) a blade bar configured to cut plant material in cooperation with the helical blades when the device is in operation; (ii) a first arm operatively associated with the blade bar; and (iii) a second arm pivotably connected to the first arm such that the second arm can pivot downward when the blade mechanism is unlocked. A tightening block may be threadedly connected to the second arm and connectable to one of the two end walls. The tightening block may be configured for adjusting the pitch of the blade bar relative to the helical blades when the blade mechanism is locked to the end walls.
