Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural vehicles lack sufficient crop clearance and adjustable machine track width, limiting their off-road capabilities and efficiency.
Innovation Solution
A king-pin height adjuster system utilizing a hydraulic lift cylinder and ram, connected to a wheel motor housing, which allows for adjustable vehicle height and track width through hydraulic and mechanical locking mechanisms, enhancing off-road clearance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional agricultural vehicles use fixed height design, then manufacturing is simple, but crop clearance is insufficient
Solution Approach 1:
The patent implements a dynamic height adjustment system where the vehicle body can be raised or lowered relative to the wheels using a hydraulic cylinder connected to the kingpin assembly. This allows the vehicle to transition between different height positions to clear crops while maintaining structural integrity through the kingpin's pivot mechanism.
Solution Approach 2:
The patent employs a hydraulic cylinder as the actuating mechanism for height adjustment. The hydraulic system provides controlled force to move the vehicle body between raised and lowered positions, enabling reliable height adjustment without excessive mechanical complexity.
2Adaptability or versatility
If track width is fixed in conventional vehicles, then structural simplicity is maintained, but off-road performance is limited
Solution Approach 1:
The kingpin assembly serves multiple functions: it acts as both the steering pivot point and the mounting structure for the hydraulic height adjustment mechanism. This multi-functionality enables track width and height adjustment without requiring separate dedicated mechanisms, thereby reducing overall system complexity while maintaining adaptability.
3Length of moving object
If height adjustment mechanism is added, then crop clearance is improved, but structural complexity increases
Solution Approach 1:
The hydraulic cylinder and ram assembly are integrated within the existing kingpin structure. The height adjustment mechanism is nested within the kingpin's structural envelope, utilizing the kingpin's pivot point and mounting locations, thereby adding height adjustment capability while minimizing additional structural complexity.
