Vehicle Frame Hinge Attachment for Adaptive Door Configurations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing four-wheel vehicles used in rough terrain often have inconsistent door sizes that do not efficiently adapt to varying environmental conditions, with full-size doors covering the entire opening in cold regions and half-size doors covering only the lower half in warm regions, leading to inefficient design and space utilization.
Innovation Solution
A vehicle design featuring a vehicle frame with separate machining and welding attachment portions for hinges, allowing for the attachment of either half-size or full-size doors, which can be positioned on either side of the passenger area, optimizing door placement and vehicle width without the door being a structural element, enabling flexible door configurations based on environmental needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If full-size doors covering the entire opening are attached to the vehicle frame, then protection against cold and improved passenger comfort are achieved, but vehicle width increases and space utilization decreases
Solution Approach 1:
The vehicle frame incorporates both upper and lower attachment portions for hinges, enabling the door configuration to dynamically adapt between full-size and half-size doors based on environmental conditions. This dynamic capability allows the vehicle to optimize between protection and space utilization depending on whether cold or warm conditions prevail.
Solution Approach 2:
The vehicle frame is designed with universal attachment capabilities that can accommodate both full-size and half-size door configurations. The presence of both upper and lower attachment portions makes the frame multi-functional, allowing it to support different door types for different operational environments, thus resolving the contradiction between protection needs and space efficiency.
2Length of moving object
If half-size doors covering only the lower half of the opening are attached, then vehicle width is reduced and space utilization is improved, but protection against cold and passenger comfort deteriorate
Solution Approach 1:
The vehicle frame allows dynamic reconfiguration between half-size and full-size door setups by providing both upper and lower hinge attachment portions. When warm conditions prevail, half-size doors can be used to reduce width and improve space utilization, while the capability to switch to full-size doors remains available when cold protection becomes necessary.
Solution Approach 2:
The frame's universal attachment design enables it to support both half-size and full-size door configurations, making the vehicle adaptable to different operational priorities. The multi-functional attachment system allows the vehicle to optimize for space efficiency when needed while maintaining the capability for enhanced protection when environmental conditions require it.
3Adaptability or versatility
If the vehicle frame is designed with separate upper and lower attachment portions for hinges, then adaptability to different environmental conditions is improved, but device complexity increases
Solution Approach 1:
The vehicle frame is segmented into distinct upper and lower attachment portions for hinges, allowing independent configuration of door sizes. This segmentation enables the frame to accommodate different door types by selectively utilizing either the upper or lower attachment portions, providing adaptability without requiring a completely redesigned frame structure for each door configuration.
Solution Approach 2:
The frame structure incorporates universal attachment features that can serve multiple door configuration purposes. By designing the frame with both upper and lower attachment portions that can accommodate hinges, the structure achieves multi-functionality, allowing the same frame to support various door configurations for different environmental conditions without proportionally increasing complexity.

AI summary
A vehicle with a passenger area having a seat disposed therein and an opening of the passenger area on the right or left sides of the seat. The vehicle frame includes an opening frame portion defining the opening of the passenger area. The opening frame portion comprises a lower attachment portion for attaching a hinge of a first door to the opening frame portion, and an upper attachment portion for attaching a hinge of a second door to the opening frame portion. The lower attachment portion and the upper attachment portion are portions formed by at least one of machining and welding. The lower attachment portion is formed in the main body frame of the vehicle frame, and the upper attachment portion is formed in the case of the vehicle frame.
