AR Glasses Multi-Layer Shell Mounting Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing AR glasses designs face inconvenience in mounting electronic devices due to the small annular groove, which limits the space and makes it difficult to install components effectively.
Innovation Solution
The AR glasses feature a frame with multiple layers of shell structures forming a mounting cavity, where at most two of the side walls and end walls are disposed on each layer, preventing the formation of a U-shaped groove that would restrict space, allowing for easier installation of electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an annular groove is provided on the frame bracket to install electronic devices, then the electronic devices can be mounted on the frame, but the small size of the annular groove makes it very inconvenient to install the electronic devices
Solution Approach 1:
The frame is divided into multiple layers of shell structures (first shell structure, second shell structure, third shell structure) with each layer containing specific side walls and end walls. This segmentation creates a distributed mounting cavity system that provides adequate installation space for electronic devices while maintaining structural integrity and ease of assembly.
Solution Approach 2:
The mounting cavity is formed by extending the structure in the thickness direction with multiple layers of shell structures. By utilizing the third dimension (thickness direction) rather than relying solely on the planar annular groove, the patent creates sufficient mounting space for electronic devices without increasing the lateral footprint.
2Device complexity
If three or more side walls are concentratedly disposed on one layer of shell structure to form a U-shaped groove, then the structure is simplified, but it forms a limited space that is inconvenient to dispose electronic devices therein
Solution Approach 1:
The side walls and end walls are segmented across multiple layers of shell structures rather than concentrating them on a single layer. Specifically, the first side wall is on the first shell structure, the second side wall is on the second shell structure, and the end walls are distributed on different layers, preventing U-shaped groove formation and providing adequate device disposal space.
Solution Approach 2:
The patent employs a modular multi-layer shell structure that can be assembled in different configurations. This dynamic assembly approach allows the side walls and end walls to be positioned on different layers, creating flexible mounting cavities that accommodate electronic devices conveniently while maintaining reasonable structural complexity.

AI summary
AR glasses comprise a frame, two glasses legs and at least one electronic device; the frame comprises multiple layers of shell structures stacked along a thickness direction of the frame which are enclosed together to form a mounting cavity disposed along a circumferential direction of the frame opening, the mounting cavity comprises a first side wall constituting a side wall of the frame opening, a second side wall away from the frame opening, and an inner end wall and an outer end wall disposed in sequence in the thickness direction of the frame, at most two of them are disposed on any one layer of shell structure. The problem of the inconvenient mounting the electronic device on the frame is improved.
