Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating radiators in motor vehicles face challenges in optimizing the spatial distribution of components on the printed circuit board, heat dissipation, and volume constraints of the power supply module, which protrudes from the housing and complicates integration under the dashboard.
Innovation Solution
The power supply module is partitioned into distinct zones - a first zone for connecting to the heating body, a second zone for electronic switches, and a third zone for connectors, arranged side by side in a transverse direction, with a T-shaped configuration, facilitating heat dissipation and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the power supply module is placed adjacent to the heating body with transverse extension, then the electronic switches remain close to the heating body for heat dissipation, but the module protrudes from the housing increasing volume
Solution Approach 1:
The power supply module is configured to extend in a plane transverse to the heating body plane, utilizing the third dimension (depth/thickness) to accommodate components. The printed circuit board extends transversely relative to the heating body plane, with electronic switches arranged in a direction transverse to the heating body extension, allowing heat dissipation proximity while maintaining compact integration within the housing constraints.
2Temperature
If the printed circuit board extends transversely relative to the heating body, then heat dissipation is improved, but the spatial distribution of conductive tracks becomes complex
Solution Approach 1:
The printed circuit board is divided into distinct functional zones: a first zone providing electrical connection with the heating body, a second zone providing electrical connection with electronic switches, and a third zone providing electrical connection with external circuits. This segmentation organizes the spatial distribution of conductive tracks into manageable sections, reducing complexity while maintaining effective heat dissipation through the transverse configuration.
3Volume of moving object
If the power supply module is integrated within the heating radiator, then compactness is improved, but heat dissipation from electronic switches becomes difficult
Solution Approach 1:
The electronic switches are positioned in a specific location within the power supply module - in a direction transverse to the extension of the heating body, adjacent to the heating body. This local positioning ensures that the heat-generating components are placed in the most favorable position for heat dissipation (close to the heating body where heat can be effectively transferred), while the overall module remains compact and integrated within the housing.
