Head Mounting Device Weight Distribution Support Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
See-closed-type head-mounted devices (HMDs) face challenges in reducing weight while maintaining functionality, leading to user fatigue due to the proximity of display panels and optical devices to the eyes, which limits comfort and adjustability.
Innovation Solution
The HMD design includes a face-worn unit with a guide member and fixing plate for secure mounting, a wearing band unit with a flexible frame and cushioning, and a support unit that distributes the device's weight, along with a flexible shielding member to alleviate pressure and improve comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If optical devices and display panels are mounted close to the user's eyes, then viewing comfort and image quality are improved, but the weight of the HMD increases and user fatigue occurs
Solution Approach 1:
The HMD is divided into separate functional modules: a face-worn unit containing optical devices and display panels, and a separate support unit with weight distribution components. This segmentation allows the heavy components to be separated from the eye-area components, reducing the effective weight at the user's eyes while maintaining viewing comfort.
Solution Approach 2:
The support unit extends the HMD structure into a third dimension by adding a head-mounted support portion that distributes weight across the user's head and face. This dimensional extension creates a weight distribution framework that reduces the concentration of weight in the traditional HMD body, alleviating user fatigue without compromising optical performance.
2Adaptability or versatility
If the HMD structure includes optical devices, display panels, and mounting structures, then functionality is improved, but the weight cannot be dramatically reduced
Solution Approach 1:
The support unit serves multiple functions simultaneously: it provides structural support for the HMD, distributes weight across the user's head, and acts as a mounting framework for the face-worn unit. This multi-functionality reduces the need for additional separate components, maintaining full HMD functionality while optimizing weight distribution.
3Ease of operation
If the HMD weight is reduced to alleviate user fatigue, then wearing comfort is improved, but the structural integrity and support capability may be compromised
Solution Approach 1:
The support unit employs composite construction combining a frame structure with cushioning members. The frame provides structural strength and weight distribution, while the cushioning members (made of soft materials) provide comfort and pressure distribution. This composite approach maintains structural integrity while maximizing wearing comfort.
