Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tying tools in agriculture face issues with accessibility and maintenance due to complex designs, leading to prolonged inactivity from wire jamming and excessive components for wire transmission, which increases space occupation and handling difficulties.
Innovation Solution
A tying tool with a gearmotor and a tying region containing a cutting portion within a box-like support, allowing quick disassembly of the blade and contrast blade, and a simplified wire transmission system using a gearmotor and conical pinion, reducing the number of components and space required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the blade and contrast blade are integrated into a complex tying region structure, then the cutting function is effective, but the accessibility for maintenance and unjamming becomes difficult
Solution Approach 1:
The tying region is divided into modular components: the blade assembly (with blade and contrast blade) can be detached as a separate unit from the handle and tying mechanism. This segmentation allows the cutting components to be accessed, removed, and maintained independently without disassembling the entire device, resolving the contradiction between effective integrated cutting function and ease of maintenance accessibility.
2Manufacturing precision
If multiple transmission components (conical pinion, annular element, gear, pinion) are used to advance the wire, then the wire feeding control is precise, but the number of components and space occupation increases
Solution Approach 1:
The patent combines multiple transmission functions into a simplified wire advancement mechanism. Instead of separate conical pinion, annular element, gear, and pinion components, the invention integrates wire feeding control into a more compact transmission system that achieves precise wire advancement with fewer parts, reducing device complexity while maintaining manufacturing precision.
Solution Approach 2:
The gearmotor serves multiple functions: it provides both the rotational motion for wire advancement and the controlled feeding mechanism through its integrated transmission system. This multi-functionality eliminates the need for separate dedicated transmission components, reducing the overall number of parts while maintaining precise wire feeding control.
3Manufacturing precision
If a complex transmission system with multiple components is used, then the wire advancement is controlled, but the space occupation and handling difficulty increase
Solution Approach 1:
The transmission components are merged into a compact integrated system within the handle assembly. The gearmotor and its transmission elements (conical pinion, annular element) are combined in a space-efficient arrangement that reduces the overall device footprint, making the tool easier to handle and maneuver while maintaining precise wire advancement control.
