Trunk Cooling via Loading Floor Air Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motor vehicles, the air available in the trunk compartment is often insufficient for cooling electrical or electronic units, such as supercapacitors and secondary batteries, which require effective ventilation to ensure stable operation.
Innovation Solution
A component system that includes a loading floor and a bodyshell component forming a passage between the loading floor and the trunk compartment area, allowing air from the vehicle interior to flow into the trunk compartment for cooling, with additional features like a cover element and cladding to enhance airflow and mechanical support, while minimizing noise and using existing ventilation elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If air from the trunk compartment is used for cooling units, then the cooling system is simple, but the air quantity available is insufficient for adequate cooling
Solution Approach 1:
The patent combines the cooling function with the existing forced venting system by integrating a passage that connects the vehicle interior through the loading floor to the trunk compartment area. This merging allows the cooling air supply to be part of the existing ventilation infrastructure rather than a separate system, thereby increasing air quantity without proportionally increasing system complexity.
Solution Approach 2:
The passage structure serves multiple functions: it provides structural support as part of the loading floor assembly, enables forced venting connectivity, and supplies cooling air to units in the trunk compartment area. This multi-functionality allows the same component to address both structural requirements and cooling requirements, increasing air quantity availability while maintaining reasonable system complexity.
2Quantity of substance
If interior air is guided outwards via forced venting for cooling units, then cooling capacity increases, but noise from the vehicle interior increases
Solution Approach 1:
The patent introduces the loading floor and its underlying structure as an intermediary element between the vehicle interior and the trunk compartment area. This intermediary structure includes the passage that routes air flow, thereby mediating the connection and allowing cooling air supply while potentially filtering or directing the flow to minimize noise transmission to the vehicle interior.
Solution Approach 2:
The patent extracts the air flow path from the direct vehicle interior space by routing it through the passage in the loading floor structure before reaching the trunk compartment area. This extraction separates the cooling air supply function from the passenger compartment, allowing adequate air quantity to be supplied to units while reducing the direct noise impact on the vehicle interior.
3Productivity
If additional components are added to enhance airflow and cooling, then cooling efficiency improves, but device complexity and cost increase
Solution Approach 1:
The loading floor structure is designed to serve multiple purposes: it provides structural support for the vehicle, creates the passage for air flow, and houses the cooling functionality. By making the loading floor multi-functional, the patent improves cooling efficiency without adding separate dedicated components, thereby avoiding increased device complexity and cost.
Solution Approach 2:
The patent merges the cooling passage integration with the existing loading floor and bodyshell component structure. Instead of adding a separate cooling duct system, the air flow passage is incorporated into the structural elements already present in the vehicle, thereby improving cooling efficiency while maintaining simplicity and avoiding additional components.
