Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The space within a motor vehicle dashboard is cluttered due to electrical and electronic boxes, which generate heat, leading to high temperatures and potential malfunctions, and existing cooling solutions are not effectively addressed.
Innovation Solution
A heat removal device with a diffuser system that directs heat outside or into the passenger compartment, using a bifurcation element and fan within a tubular crosspiece, allowing for efficient cooling or heating management based on compartment requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electrical and electronic boxes are installed within the dashboard, then the dashboard functionality is improved, but the temperature within the dashboard increases due to heat generation
Solution Approach 1:
The patent extracts the heat generated by electronic boxes from the dashboard interior by introducing an evacuation duct that channels hot air from the dashboard space to an external discharge location, thereby removing the harmful thermal energy from the confined dashboard environment
Solution Approach 2:
The patent introduces an intermediary evacuation system comprising a duct and diffuser that mediates between the heat-generating electronic boxes and the dashboard interior, transferring heat away from the passenger compartment while allowing the electronic boxes to remain functional within the dashboard
2Temperature
If existing cooling solutions are implemented, then heat removal is achieved, but the device complexity and space occupation increase
Solution Approach 1:
The patent merges the heat evacuation function with the existing dashboard structure by utilizing the tubular crosspiece as both a structural support element and a heat evacuation duct, thereby eliminating the need for separate cooling system components and reducing overall device complexity
Solution Approach 2:
The patent makes the tubular crosspiece multi-functional by using it simultaneously as a structural support member of the dashboard and as a thermal evacuation conduit, allowing one component to serve multiple purposes and reducing the number of additional parts required
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
