Adjustable Vehicle Body Height for Crop-Clearing Work Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working vehicles cannot adjust the height of the vehicle body to accommodate different types of work or navigate through crops of varying heights, leading to difficulties in traveling between left and right traveling devices.
Innovation Solution
A working vehicle equipped with a height changing mechanism that allows the vehicle body to adjust its height between a first and second height, controlled by a recognizer, manual operator, or situation detector, to accommodate various working devices and crop heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle body height is fixed, then the structure is simple, but the vehicle cannot adapt to different working devices or crop heights
Solution Approach 1:
The vehicle body height is made dynamically adjustable through a height changing mechanism that can raise and lower the vehicle body between a first height and a second height. This allows the vehicle to adapt to different working devices and crop heights while maintaining structural simplicity through automated control.
Solution Approach 2:
The height parameter of the vehicle body is made changeable through the height changing mechanism, which adjusts the vertical position of the vehicle body based on operational requirements. This parameter change enables versatility without requiring multiple fixed-height vehicle configurations.
2Reliability
If the vehicle body height is fixed, then the structure is simple, but the vehicle cannot travel with crops of varying heights
Solution Approach 1:
The vehicle body height is dynamically adjusted based on crop height requirements. The height changing mechanism enables the vehicle to raise or lower its body to match the height of crops being worked, ensuring reliable travel through fields with varying crop heights.
Solution Approach 2:
The system uses a recognizer to detect the type of working device attached to the vehicle body, and this information feeds back to the height changing mechanism controller, which automatically adjusts the vehicle body height to the appropriate level for the detected working device and crop conditions.
3Adaptability or versatility
If the vehicle body cannot be raised or lowered between traveling devices, then the structure is simple, but the vehicle cannot change height when crops are taller than expected
Solution Approach 1:
The vehicle body is equipped with a height changing mechanism that allows dynamic adjustment of the vehicle body height between the left and right traveling devices. This enables the vehicle to adapt to taller crops by raising the vehicle body to an appropriate height for safe and effective operation.
4Adaptability or versatility
If a height changing mechanism is added, then the vehicle can adapt to different working devices, but the device complexity increases
Solution Approach 1:
The height changing mechanism serves multiple functions: it adjusts the vehicle body height for different working devices, enables travel through crops of varying heights, and works in conjunction with the recognizer system to automatically configure the vehicle for the detected working device. This multi-functionality justifies the added complexity.
Solution Approach 2:
The recognizer detects which working device is attached to the vehicle body and provides feedback to the height changing mechanism controller. This automated feedback loop allows the system to automatically adjust the vehicle body height to the optimal level for the detected working device, reducing manual intervention and improving operational efficiency.

AI summary
A working vehicle includes a vehicle body, a traveling device to support the vehicle body such that the vehicle body is allowed to travel, and a height changing mechanism to change a height of the vehicle body that is a distance of the vehicle body from a ground surface. The height changing mechanism is configured to change the height of the vehicle body to any height between a first height and a second height higher than the first height.
