Keyboard Frame Airflow Paths for Laptop Cooling and Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses, such as laptop PCs, face challenges in improving cooling performance while maintaining the rigidity and operability of the keyboard device, as conventional designs limit air intake volume and exacerbate temperature rise due to inadequate heat dissipation from the keyboard area.
Innovation Solution
The design incorporates a frame with notched partition walls that form communicating paths between key arrangement holes, allowing for a varying height and cross-sectional area of air flow paths, which enhances air intake for the fan device without compromising the keyboard's rigidity and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the installation range of the opening is increased to improve cooling performance, then the air intake volume of the fan device is increased, but the rigidity and strength of the keyboard device decrease
Solution Approach 1:
The partition walls are notched only in specific regions (first and second regions) rather than uniformly across the entire keyboard device. This localized modification allows air to pass through the frame structure in areas where it does not compromise the overall rigidity, while maintaining the structural integrity of the keyboard device in critical areas.
Solution Approach 2:
The frame is divided into multiple partition walls that are selectively notched. By segmenting the frame structure and applying notches only to specific partition walls in specific regions, the design enables differentiated air flow paths that balance cooling performance with structural strength requirements.
2Stability of the object's composition
If the frame structure surrounds each key cap to maintain keyboard structure, then the heat transferred from inside the chassis is trapped, but the temperature rise of the keyboard device worsens
Solution Approach 1:
The partition walls are notched in specific regions (first and second regions) to create localized heat dissipation pathways. This allows heat to escape from the chassis through the frame structure in areas where it does not compromise the overall keyboard structure, while maintaining structural integrity in critical areas.
3Ease of manufacture
If the communicating path height is uniform across all regions to simplify manufacturing, then the air intake efficiency is reduced, but the cooling performance in fan device regions is insufficient
Solution Approach 1:
The communicating path height is differentiated by region: the first region (overlapping the fan device) has a greater height to maximize air intake efficiency and cooling performance, while the second region has a smaller height that maintains sufficient structural strength. This localized differentiation optimizes both cooling efficiency and structural integrity.
Solution Approach 2:
The communicating path height varies dynamically across different regions of the frame to match the functional requirements of each area. The first region requires greater height for effective cooling, while the second region requires smaller height for structural strength, creating a dynamic adaptation of the air flow path geometry.

AI summary
An electronic apparatus includes a chassis, a keyboard device, a frame including partition walls, and a fan device. At least part of the partition walls has a bottom edge surface notched to form an air flow path between the notched bottom edge surface and a top surface of the plate-shaped member, to have a communicating path through which adjacent key arrangement holes communicate. A height of the communicating path in a region not overlapping with the fan device is lower than a height of the communicating path in a region overlapping with the fan device, in a plan view of the chassis.
