Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous agricultural machinery lacks sufficient power for heavy-duty operations and integrating a diesel-type thermal engine system requires increased volume, leading to stability and safety issues due to increased height and bulk.
Innovation Solution
An autonomous agricultural machine equipped with a split thermal engine system and a specific cooling system, featuring an air circulation gallery and ventilation device to cool the engine without increasing the machine's size or height, and a motorization system with an exhaust device and air filter arranged to maintain compact dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a diesel-type thermal engine system is integrated to increase power output, then the power is improved, but the volume and height of the machine must be increased
Solution Approach 1:
The patent utilizes the vertical space above the wheelbase by positioning the engine and cooling system components in the upper portion of the machine frame, effectively using the third dimension (height) to accommodate powertrain components without increasing the machine's footprint or length. This allows high-power diesel engine integration while maintaining compact horizontal dimensions.
2Power
If the machine height is increased to accommodate the thermal engine system, then the power is improved, but the stability deteriorates due to increased center of gravity
Solution Approach 1:
The patent segments the machine into distinct functional zones: the lower portion contains the wheelbase and operational components for stability, while the upper portion houses the engine and cooling system. This vertical segmentation allows the heavy engine components to be positioned high for space efficiency while the lower mass distribution maintains operational stability during agricultural operations.
3Power
If equipment is arranged in longitudinal offset to accommodate the thermal engine system, then the power is improved, but the safety deteriorates due to unpredictable tool positions and trajectories
Solution Approach 1:
The patent creates a universal mounting structure and standardized positioning system for tools and equipment that ensures all components remain within predictable trajectories regardless of the high-power engine configuration. The frame structure provides standardized attachment points that maintain consistent tool positions relative to the wheelbase, ensuring safe and predictable operation.
