Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information handling systems face challenges in efficiently managing heat and maintaining functionality, particularly due to the accumulation of heat from components like processors and graphics devices, which can lead to reduced performance and potential damage from liquid spills.
Innovation Solution
A vented keyboard assembly with a keyboard carrier featuring a venting portion comprising multiple apertures beneath the keys, designed to enhance airflow and facilitate heat dissipation, while also incorporating a mesh component for spill resistance and an adhesive to secure the mesh over the apertures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional solid keyboard assembly is used, then liquid spill resistance is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The keyboard carrier incorporates a venting portion with multiple venting apertures that allow heat to pass through while maintaining structural integrity. This porous-like structure enables thermal ventilation without compromising the keyboard's protective function against liquid spills.
Solution Approach 2:
A mesh component is introduced as an intermediary element positioned over the venting apertures. The mesh allows heat to pass through while blocking liquid spills, effectively mediating between the conflicting requirements of heat dissipation and liquid protection.
2Temperature
If venting apertures are added to the keyboard carrier, then heat dissipation capability is improved, but liquid spill resistance deteriorates
Solution Approach 1:
The mesh component serves as a mediator that is positioned over the venting apertures in the keyboard carrier. It allows thermal energy to pass through while physically blocking liquid spills, thus resolving the contradiction between heat dissipation and liquid protection.
Solution Approach 2:
The solution combines the keyboard carrier material with a mesh material to create a composite structure. This composite enables both functions: the carrier provides structural support and venting apertures for heat dissipation, while the mesh layer provides liquid spill resistance.
3Reliability
If a mesh component is added over the venting apertures, then liquid spill resistance is improved, but device complexity increases
Solution Approach 1:
The mesh component is integrated with the keyboard carrier assembly, merging two functional elements (venting and liquid protection) into a single unified structure. This reduces the need for separate components and simplifies the overall assembly process.
Solution Approach 2:
The mesh component performs multiple functions simultaneously: it blocks liquid spills while allowing heat to pass through, and it also serves as a structural element of the keyboard assembly. This multi-functionality reduces the need for additional specialized components.
4Temperature
If the keyboard assembly is designed with venting portion and mesh component, then manufacturing complexity increases, but heat dissipation and liquid spill resistance are improved
Solution Approach 1:
The keyboard assembly is segmented into distinct functional components: the keyboard carrier with integrated venting apertures, the mesh component, and the adhesive layer. This segmentation allows each component to be manufactured separately using optimized processes and then assembled, reducing overall manufacturing complexity.
Solution Approach 2:
The venting portion is integrated directly into the keyboard carrier structure, merging the carrier and venting functions into a single manufactured component. This eliminates the need for separate venting components and reduces assembly steps.
