VR Headset Cooling Module Using Peltier Element and Ducts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality (VR) headsets become hot and fogged during prolonged use, leading to user discomfort and decreased performance due to increased ambient temperature and humidity within the headset.
Innovation Solution
A cooling module incorporating a Peltier element with a blower on the cold side and a fan on the hot side, along with ducts for air circulation, is integrated into the VR headset to manage temperature and humidity levels, optionally controlled by user-adjustable settings or sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling module with Peltier element, blower, and fan is integrated into the VR headset, then temperature and humidity control is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple cooling components (Peltier element, blower, fan, ducts) into a single integrated cooling module that is incorporated into the VR headset structure. This merging approach achieves effective temperature and humidity control while minimizing the overall space required and reducing the number of separate assemblies needed.
Solution Approach 2:
The cooling module serves multiple functions simultaneously: the Peltier element provides active cooling, the blower circulates air through the viewing module, the fan exhausts hot air, and the ducts distribute cooled air. This multi-functionality allows a single integrated system to address both temperature control and humidity management in the VR headset.
2Ease of operation
If active cooling components are added to the VR headset, then user comfort is improved, but weight of the headset increases
Solution Approach 1:
The cooling system is designed to provide localized cooling only in the viewing module area where heat accumulation occurs during VR usage. The Peltier element is positioned to cool specifically the air in contact with the user's face, while the blower and ducts deliver cooled air precisely to the needed location, avoiding the need for cooling the entire headset structure.
Solution Approach 2:
The system applies cooling action selectively to the critical viewing module region rather than attempting to cool the entire headset. The blower and fan are sized to provide sufficient cooling airflow for the viewing module without over-engineering the system, thereby minimizing weight while achieving the necessary comfort level for the user.

AI summary
Systems for cooling a virtual reality (VR) headset, including a viewing module that includes a VR display; and a cooling module that includes: a Peltier element having a cold side and a hot side; a blower mounted on the cold side of the Peltier element and configured to draw air across the cold side of the Peltier element and into a first duct; and a fan mounted on the hot side of the Peltier element and configured to draw air from a second duct, where a portion of the first duct and a portion of the second duct are positioned within the viewing module, and where each of the portions includes multiple openings.
