HMD Mask Cantilever Structure for Adaptive Face Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display devices suffer from poor adaptability to different face shapes due to limited deformability of the mask, leading to a poor wearing experience.
Innovation Solution
The mask incorporates a support system with forehead and zygomatic cantilevers and a face-fitting elastic support that can elastically bend and rotate, allowing adaptive deformation to fit various face shapes, enhanced by a face-fitting cushion and ball joint structure for improved comfort and fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mask uses a rigid support structure, then the structural strength is improved, but the adaptability to different face shapes deteriorates
Solution Approach 1:
The support structure is divided into multiple segments including a rigid main support and flexible cantilevers (forehead cantilever and zygomatic cantilever). This segmentation allows different parts to serve different functions: the main support provides structural strength while the cantilevers provide adaptability through elastic deformation.
Solution Approach 2:
The mask transitions from a static rigid structure to a dynamic structure with components that can change shape. The forehead and zygomatic cantilevers are designed to elastically bend and rotate, allowing the mask to dynamically adapt to various face shapes while maintaining overall structural integrity.
2Adaptability or versatility
If the mask uses a highly deformable structure, then the adaptability to different face shapes is improved, but the structural strength deteriorates
Solution Approach 1:
The support structure is divided into multiple segments including a rigid main support and flexible cantilevers (forehead cantilever and zygomatic cantilever). This segmentation allows different parts to serve different functions: the main support provides structural strength while the cantilevers provide adaptability through elastic deformation.
Solution Approach 2:
Different parts of the mask have different mechanical properties tailored to their specific functions. The main support is rigid for strength, while the forehead and zygomatic cantilevers are flexible for adaptation. The face-fitting cushion is soft for comfort. This local differentiation of material properties resolves the contradiction between overall strength and local adaptability.
3Ease of manufacture
If the mask structure is simplified, then the ease of manufacture is improved, but the adaptability to different face shapes deteriorates
Solution Approach 1:
The mask transitions from a static rigid structure to a dynamic structure with components that can change shape. The forehead and zygomatic cantilevers are designed to elastically bend and rotate, allowing the mask to dynamically adapt to various face shapes while maintaining overall structural integrity.
Solution Approach 2:
The mask achieves adaptability by changing geometric parameters of existing components rather than adding complex mechanisms. The cantilevers change their bending radius and rotation angles to adapt to different face shapes, providing versatility through parameter variation of a relatively simple structure.
4Manufacturing precision
If the mask applies more force to fit the face, then the fitting precision is improved, but the comfort deteriorates due to squeezing
Solution Approach 1:
Different parts of the mask have different mechanical properties tailored to their specific functions. The main support is rigid for strength, while the forehead and zygomatic cantilevers are flexible for adaptation. The face-fitting cushion is soft for comfort. This local differentiation of material properties resolves the contradiction between overall strength and local adaptability.
Solution Approach 2:
The mask transitions from a static rigid structure to a dynamic structure with components that can change shape. The forehead and zygomatic cantilevers are designed to elastically bend and rotate, allowing the mask to dynamically adapt to various face shapes while maintaining overall structural integrity.
