Vehicle Frame Assembly for Extended Height Adjustment Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle height adjustment systems struggle to sufficiently lower the vehicle body to the desired height due to a small adjustable gap between the vehicle body and the axle, making it difficult to unload or load items and navigate rough terrain.
Innovation Solution
A frame assembly with vehicle height adjustment parts that include a beam, axles, and power providing regions to raise or lower the beam relative to the axles, utilizing motors or hydraulic cylinders to adjust the vehicle height, controlled by a controller for precise height adjustments based on driver input or topographic data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional vehicle height adjustment system is used, then the vehicle height can be adjusted to some extent, but the adjustable gap is small and the vehicle body cannot be sufficiently lowered to the desired height
Solution Approach 1:
The height adjustment system is divided into multiple adjustment stages: a first height adjustment part that adjusts the beam position relative to the axle, and a second height adjustment part that adjusts the vehicle body position relative to the beam. This segmentation allows for cumulative height adjustment beyond what a single mechanism could achieve, enabling the vehicle body to be lowered to the desired height.
Solution Approach 2:
The beam serves as an intermediary component between the vehicle body and the axle. By introducing this intermediate element, the system can achieve greater height adjustment range through coordinated movement of the beam and vehicle body, overcoming the limitation of direct adjustment between vehicle body and axle.
2Ease of operation
If the vehicle body height is decreased to facilitate loading and unloading, then accessibility is improved, but the interval between the vehicle body and ground surface becomes too small
Solution Approach 1:
The height adjustment system is designed to be dynamically adjustable, allowing the vehicle to switch between different height configurations based on operational needs. The vehicle can be lowered for loading/unloading operations and raised for traversing rough terrain, providing dynamic adaptability to different conditions.
Solution Approach 2:
The system changes the height parameter of the vehicle body relative to the ground surface based on different operational requirements. By adjusting the height parameter dynamically, the vehicle can optimize for either accessibility during loading/unloading or terrain clearance during travel.
3Adaptability or versatility
If the vehicle body height is increased to navigate rough roads, then terrain clearance is improved, but the interval for loading and unloading items becomes too large
Solution Approach 1:
The height adjustment system enables dynamic reconfiguration of the vehicle height based on the operational context. When encountering rough terrain, the vehicle raises its height for clearance; when at a destination for loading/unloading, it lowers its height for accessibility.
Solution Approach 2:
The system adjusts the height parameter in response to different operational conditions, changing from a high configuration optimized for terrain clearance to a low configuration optimized for loading and unloading operations.

AI summary
A frame assembly for a vehicle body includes a beam, axles, and vehicle height adjustment parts. The beam is configured to be connected to a lower portion of the vehicle body and extend in a width direction of the vehicle body. The axles are disposed at two opposite sides of the beam and configured to receive tires, the tires being mounted on the axles. The vehicle height adjustment parts are configured to be connected to the beam and the axles and configured to raise or lower the beam relative to the axles to thereby adjust a vehicle height, where the vehicle height corresponds to a height of the vehicle body with respect to a ground surface.
