Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatus designs with power circuits suffer from reduced ventilation efficiency due to misaligned air vents between the power circuit case and the housing, leading to unnecessary space and compromised cooling performance.
Innovation Solution
The electronic apparatus features a power circuit case with strategically aligned air vents that match the housing's openings, ensuring optimal airflow and preventing unnecessary space, while also incorporating a louver for improved aesthetics and assembly simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air vents of the case and housing are arranged facing each other to improve ventilation efficiency, then ventilation efficiency is improved, but misalignment between the air vents causes unnecessary space and reduced cooling performance
Solution Approach 1:
The patent merges the case wall with the housing opening by making the case wall form part of the housing structure. The air vent in the case wall is positioned to align with the opening in the housing, creating a continuous airflow path without gaps or unnecessary space between components.
Solution Approach 2:
The case wall is designed with specific local properties: it includes an air vent at a specific position and shape that corresponds to the housing opening. This localized design ensures optimal airflow through the power circuit while maintaining structural integrity of the housing.
2Productivity
If the case wall is exposed through the housing opening to improve ventilation, then ventilation efficiency is improved, but the housing strength may be compromised
Solution Approach 1:
The case wall is integrated into the housing structure such that it forms a continuous load-bearing element. The wall is positioned and configured to work together with the housing, providing both ventilation functionality and structural support without compromising overall housing strength.
3Productivity
If air vents are formed in the entire region of the wall to maximize ventilation, then ventilation efficiency is improved, but the external appearance may be compromised
Solution Approach 1:
The air vent is positioned at a specific location on the case wall rather than being distributed across the entire surface. This localized placement optimizes airflow through the power circuit while maintaining a clean, aesthetically pleasing external appearance of the housing.
