AR Headset Skeleton Unit for Stability and Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Augmented Reality (AR) headsets lack stability, especially in non-protected environments like manufacturing or maintenance, which can lead to damage and reduced wearing comfort.
Innovation Solution
The AR headset features a beam-shaped frame with a skeleton extending along the shell, supporting electronic components and forming a skeleton unit that can be mounted as a whole, enhancing stability and allowing for thinner, lighter components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic components are mounted individually in the shell, then assembly flexibility is maintained, but stability and durability are reduced
Solution Approach 1:
The headset is divided into distinct modules: a skeleton unit containing electronic components, an optical unit, and a shell. This segmentation allows the skeleton unit to be pre-assembled and tested independently, then mounted as a single module into the shell, improving stability while maintaining assembly flexibility.
Solution Approach 2:
The skeleton unit with electronic components is pre-assembled and pre-tested before being integrated into the final headset. This preliminary assembly ensures proper positioning and connections are established early, improving overall stability and making final assembly simpler.
2Reliability
If thicker components are used for the cover and shell, then stability is improved, but weight increases and wearing comfort deteriorates
Solution Approach 1:
The skeleton is designed with a curved shape that naturally distributes mechanical stresses throughout the structure. This curvature provides structural strength and stability without requiring excessive material thickness, thereby maintaining lightweight construction while improving durability.
Solution Approach 2:
The headset employs composite construction combining the skeleton (provideing structural support), the shell (提供保护), and strategic placement of electronic components. This composite approach optimizes the strength-to-weight ratio, achieving stability without excessive thickness or weight.
3Reliability
If multiple screws and fixation means are used, then component security is improved, but the contour is disrupted and appearance is degraded
Solution Approach 1:
Multiple fixation points and screws are consolidated into integrated fixation elements that are part of the skeleton unit itself. The skeleton incorporates built-in attachment features that secure components without requiring external screws visible on the headset contour, maintaining a clean appearance while ensuring component security.
4Ease of manufacture
If assembly is performed by less trained personnel, then manufacturing costs are reduced, but assembly quality may deteriorate
Solution Approach 1:
The headset is segmented into pre-assembled units (skeleton unit with electronics, optical unit) that can be manufactured and tested independently by specialized teams. This allows complex precision work to be done by trained personnel in controlled settings, while final assembly can be performed by less trained personnel with simpler tasks, maintaining both quality and cost efficiency.
Solution Approach 2:
Complex assembly steps are performed in advance during skeleton unit fabrication, including electronic component mounting and internal wiring. This preliminary preparation reduces the skill level required for final headset assembly, allowing less trained personnel to achieve high quality results by simply integrating pre-prepared modules.

AI summary
An Augmented Reality headset comprises a beam-shaped frame (1) with an elongate shell (10) and with first electronic components arranged within the shell (10) and an optical unit (2) extending from the frame (1). The frame (1) comprises a skeleton (11) extending along the shell (10) and being arranged within the shell (10). The first electronic components are mounted on the skeleton (11), the first electronic components and the skeleton (11) forming together a skeleton unit which can be mounted as a whole in the shell (10). The inventive skeleton enables a preassembled skeleton unit. This facilitates the assembly and enhances the stability of the beam shaped frame.
