Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices and electronic apparatuses face challenges in efficiently cooling components due to inadequate airflow management, leading to reduced heat radiation efficiency and potential overheating.
Innovation Solution
Incorporating a wind shielding portion within the housing that partitions the internal space into distinct chambers, with a cooling fan that draws fresh air and discharges it to specific components, such as the CPU and heat sink, while preventing heated air from recirculating and improving airflow focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling fan is installed in the housing to cool components, then heat radiation efficiency is improved, but the housing thickness increases due to the need for additional cooling space and airflow paths
Solution Approach 1:
The housing internal space is segmented into a first space and a second space by a wind shielding portion. The first space contains the cooling fan and is configured to supply cool air, while the second space contains heat-generating components. This segmentation allows efficient cooling of specific components without requiring the entire housing to be thicker, as the cooling function is localized to specific zones.
Solution Approach 2:
The wind shielding portion creates localized cooling zones with different air flow characteristics. The first space is designed with properties suitable for air circulation and cooling fan operation, while the second space is optimized for housing heat-generating components. This local differentiation allows effective cooling where needed without uniformly increasing housing thickness.
2Length of stationary object
If the housing is made thinner to reduce device size, then device compactness is improved, but airflow management becomes inadequate leading to reduced cooling efficiency
Solution Approach 1:
The wind shielding portion extends in the thickness direction of the housing, creating three-dimensional spatial separation between the cooling fan space and the component housing space. This vertical/directional segmentation allows efficient cooling airflow paths to be established within the limited thickness of the housing, without requiring increased overall device size.
3Temperature
If the internal space is partitioned into multiple chambers with a wind shielding portion, then airflow focus and cooling efficiency are improved, but device complexity increases
Solution Approach 1:
The wind shielding portion serves multiple functions simultaneously: it acts as a physical partition between spaces, a shield to control air flow direction, and a structural element that can be integrated with the housing or cooling fan assembly. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving improved airflow focus.
