VR Glasses Head-Mounted Device Segmentation Heat Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional VR glasses face issues of poor portability and discomfort due to heavy weight and excessive heat generation, affecting user experience.
Innovation Solution
The design includes a head-mounted device and a separate main control handle with USB and video interfaces for input and power supply, minimizing heat generation and enhancing portability by using a power unit in the handle to power the head-mounted device, along with features like Bluetooth/WIFI modules, posture sensors, and Type-C interfaces for improved compatibility and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the VR glasses are based on Samsung cell phones inserted into head-mounted parts, then input sources can be acquired from the cell phones, but the head-mounted parts become heavy and generate excessive heat, making them uncomfortable to wear
Solution Approach 1:
The VR system is divided into two separate parts: a lightweight head-mounted display (HMD) and a separate smartphone device. The HMD contains only the essential display optics and interface, while the smartphone provides computing power, processing, and input source generation. This segmentation allows the HMD to remain lightweight and cool while maintaining full functionality through the smartphone connection.
Solution Approach 2:
The HMD acts as an intermediary device between the smartphone and the user's eyes. It receives video signals and power from the smartphone via USB interface, processes them through minimal onboard circuitry, and presents the virtual reality experience through optical lenses, while the smartphone handles all heavy computational tasks.
2Adaptability or versatility
If the VR glasses are based on Samsung cell phones inserted into head-mounted parts, then input sources can be acquired from the cell phones, but excessive heat is generated by the head-mounted parts, making them uncomfortable to wear
Solution Approach 1:
The heat-generating components (processor, memory, power management) are extracted from the head-mounted display and placed in the separate smartphone device. The HMD retains only the essential display optics and minimal interface circuitry, eliminating the primary heat sources from the wearable portion while maintaining full system functionality.
3Adaptability or versatility
If the VR glasses are based on computers or gaming machines, then input sources can be acquired from these devices, but the portability is poor and carrying is inconvenient for users
Solution Approach 1:
The system uses a smartphone as the computing platform, which is a universally carried device that most users already have. The HMD can work with any smartphone that meets the minimum specifications, providing universal compatibility without requiring dedicated gaming machines or computers. This approach leverages the existing portability of smartphones while adding VR functionality.
