Innovation Solution
An electric tractor with a frame equipped with safety wheels, adjustable handle units, and power units to facilitate maneuverability and adjustability, including a motor-driven power unit and adjustable tractor head positioning for various terrain conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a forklift is used for transportation, then transportation efficiency is improved and labor intensity is reduced, but manufacturing cost, device complexity, and operation difficulty increase
Solution Approach 1:
The forklift is divided into modular components including a handle unit, tractor head, power unit, and frame that can be independently manufactured and assembled. This segmentation simplifies the overall structure while maintaining transportation functionality, directly addressing the contradiction between improved productivity and reduced device complexity
Solution Approach 2:
The tractor head is designed with universal adaptability to accommodate different loading tools and transportation requirements. The standardized interface between the tractor head and various attachments enables one base unit to perform multiple functions, reducing the need for specialized equipment and thereby simplifying overall device complexity while maintaining high productivity
2Productivity
If a forklift is used for transportation, then transportation efficiency is improved, but operation difficulty and maintenance cost increase
Solution Approach 1:
The power unit is designed with a detachable battery pack that can be easily removed and replaced by the operator without requiring specialized maintenance skills. The simple electrical connection system allows users to perform basic maintenance themselves, reducing operation difficulty while maintaining transportation efficiency
Solution Approach 2:
The power unit is extracted as a separate, independently replaceable module from the main tractor body. This extraction allows operators to quickly swap battery packs or power units without affecting other components, significantly reducing operation difficulty and maintenance time while preserving high productivity
3Productivity
If a forklift is used for transportation, then labor intensity is reduced, but manufacturing cost and device complexity increase
Solution Approach 1:
The frame is designed as a segmented structure with standardized connection points for the handle unit, tractor head, and power unit. This segmentation allows each component to be manufactured separately using simpler, less expensive processes, then assembled into a complete system that achieves high transportation efficiency without excessive manufacturing cost
Solution Approach 2:
The handle unit and tractor head are merged into a compact integrated assembly that shares common structural elements and mounting mechanisms. This merging reduces the total number of parts and simplifies manufacturing processes, lowering production costs while maintaining the mechanical advantage and efficiency of forklift-based transportation
