Trailer Underfloor Storage for Towing Vehicle Emission Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enhance the environmental friendliness of motorized towing vehicles without reducing the payload volume of road vehicle combinations, given the limited installation space and legal requirements for larger exhaust and fuel systems due to emission standards.
Innovation Solution
A commercial vehicle trailer with a chassis and vehicle frame is equipped with a supply and/or storage device below the loading area, which provides energy and resources to the towing vehicle, allowing for the relocation of necessary components from the towing vehicle to the trailer, thus saving space and maintaining payload capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If additional technical components are installed in the towing vehicle to comply with emission standards, then environmental friendliness is improved, but installation space is reduced and payload volume decreases
Solution Approach 1:
The patent extracts the supply and storage devices (fuel tanks, fluid reservoirs) from the towing vehicle and relocates them to the trailer. This extraction resolves the contradiction by removing the space-consuming components from the towing vehicle's limited installation space while ensuring emission compliance through proper component sizing in the trailer.
Solution Approach 2:
The patent utilizes the vertical dimension and unused spaces within the trailer structure (below the loading area, between side members) to accommodate the supply and storage devices. This dimensional approach allows components to be placed in locations that do not compromise the towing vehicle's payload volume while maintaining full functionality.
2Object-affected harmful factors
If the towing vehicle is enlarged to accommodate larger exhaust systems and cooling systems, then emission compliance is improved, but the total length is limited by law and payload volume is reduced
Solution Approach 1:
The patent extracts the supply and storage devices from the towing vehicle and relocates them to the trailer. This extraction resolves the contradiction by removing the space-consuming components from the towing vehicle's limited installation space while ensuring emission compliance through proper component sizing in the trailer.
Solution Approach 2:
The trailer is designed to serve multiple functions: it carries cargo in the loading area and simultaneously houses the supply and storage devices in its lower sections. This multi-functionality allows the system to meet emission requirements without requiring the towing vehicle itself to be enlarged.
3Volume of moving object
If supply and storage devices are relocated to the trailer, then installation space in the towing vehicle is saved, but space utilization in the trailer must be optimized
Solution Approach 1:
The patent utilizes the vertical dimension and unused spaces within the trailer structure (below the loading area, between side members) to accommodate the supply and storage devices. This dimensional approach allows components to be placed in locations that do not compromise the towing vehicle's payload volume while maintaining full functionality.
Solution Approach 2:
The patent places different components in specific locations within the trailer based on their functional requirements and space availability. Supply devices are positioned in areas with adequate clearance and accessibility, while storage devices are placed in spaces that would otherwise be unused, optimizing the overall space utilization of the trailer.
