Vegetable Cutter Blade Adjustment Structure With Knob-Driven Lifting Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-functional vegetable cutters face difficulties in manual adjustment of cutting mechanisms due to inconvenient screw piles that protrude beyond the cutter and are not ideally laid out, leading to a cumbersome operation.
Innovation Solution
A cutting mechanism with a frame and vertical cutting assemblies driven by a knob through a gear and gear rack system, allowing for simple and stable adjustment of cutting blades via a lifting frame and locking structure, enabling easy switching between operating and retracted states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a screw pile is used to adjust the cutting blade position, then the cutting blade state can be adjusted, but the screw pile protrudes beyond the cutter and is difficult to manually adjust
Solution Approach 1:
The patent inverts the adjustment mechanism from a protruding screw pile to a recessed knob. The knob is rotatably connected inside the housing and drives the cutting blade through internal gear mechanisms, making the adjustment interface accessible and compact while maintaining full adjustment functionality.
Solution Approach 2:
The patent introduces a gear and gear rack as intermediary elements between the knob and the cutting blade. The knob rotates the gear, which moves the gear rack along a guide groove, thereby translating rotational motion into linear motion that adjusts the cutting blade position, solving both the manual adjustment difficulty and the layout problem.
2Adaptability or versatility
If a screw pile is used to adjust the cutting blade, then adjustment is possible, but manual adjustment is difficult and operation is inconvenient
Solution Approach 1:
The patent replaces the direct linear adjustment mechanism (screw pile) with a rotational mechanism (knob + gear + gear rack). This substitution transforms the adjustment operation from difficult linear pushing/pulling to easy rotational turning, while maintaining the full range of cutting blade position adjustment through the guide groove and gear rack system.
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 solution provides a simple, convenient, and properly spaced layout for adjusting cutting blades, enhancing operational stability and ease of use by allowing simultaneous adjustment of multiple cutting assemblies with a single knob and locking mechanism.
Implementation Method 1
the frame is rotatably provided with a knob driving the lifting frame to move, and the knob drives the lifting frame via a gear and a gear rack
Implementation Method 2
a locking spring is disposed between the locking block and the locking chute, and the locking block abuts against the locking plane
