Removable Door Vehicle Accessories with Integrated Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor vehicles with removable doors lack functional accessories that provide additional benefits such as improved access, visibility, and utility when traditional doors are removed, particularly in off-road situations.
Innovation Solution
The assembly includes connectors to attach accessories like covers, grab handles, light bars, and furniture to the vehicle's attachment components, which can also enclose electrical interfaces and feature integrated lights, sensors, and mounting options for additional devices, enhancing functionality and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional doors are removed from the vehicle, then access to the vehicle and driver visibility are improved, but the vehicle lacks functional accessories and protection for attachment components
Solution Approach 1:
The attachment component is designed to serve multiple functions: it provides structural support for door mounting, enables attachment of various accessories (covers, grab handles, lights, furniture), and protects electrical interfaces. This multi-functional design resolves the contradiction by allowing the same component to provide both easy access (when doors are removed) and functional versatility (through accessory attachment).
2Illumination intensity
If traditional doors are removed from the vehicle, then driver visibility of ground surface is improved, but the vehicle lacks protection for attachment components and electrical interfaces
Solution Approach 1:
The protective cover is designed to selectively cover only the attachment components and electrical interfaces that need protection, while leaving the rest of the vehicle structure exposed for visibility. This extraction approach provides targeted protection without compromising the visibility benefit of door removal.
Solution Approach 2:
The protective cover acts as an intermediary element between the attachment components/electrical interfaces and the external environment. It mediates by providing protection from environmental factors while allowing the attachment components to remain functional and accessible when needed.
3Adaptability or versatility
If accessories are added to the vehicle body, then functionality and utility are enhanced, but the vehicle structure becomes more complex
Solution Approach 1:
The accessory system is segmented into separate, modular components: the attachment component mounted on the vehicle body, the protective cover, and various detachable accessories (lights, grab handles, furniture). This segmentation allows each component to be independently designed, installed, and removed, simplifying the overall vehicle structure while maintaining high functionality.
Solution Approach 2:
The accessory system is designed to be dynamic and reconfigurable. Accessories can be attached and detached as needed, and the protective cover can be selectively installed. This dynamic approach allows the vehicle structure to remain simple in its base form while accommodating complex functionality when accessories are added.
4Ease of operation
If multiple accessories are mounted to the vehicle, then utility and user-friendliness are improved, but installation and configuration become more difficult
Solution Approach 1:
The attachment component is designed with universal mounting capabilities that can accommodate multiple different accessory types (covers, grab handles, lights, furniture). This universal design simplifies installation by using a standardized interface rather than requiring custom mounting solutions for each accessory type, thereby improving ease of manufacture and installation while enhancing user-friendliness.
