Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VR, AR, and XR glasses are top-heavy due to components at the front end, causing them to skew and slide during wear, necessitating frequent manual adjustment, which is inconvenient when both hands are occupied.
Innovation Solution
An automatic righting system with a discrimination calibration module, including a distance sensing unit and a push-up air cushion, controlled by a controller to adjust the glasses' position automatically based on detected distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the front end of the glasses is equipped with heavy components (lenses, circuit boards, fans), then the optical and functional performance is improved, but the glasses become top-heavy and easily skew and slide during wearing
Solution Approach 1:
The patent introduces a balance weight at the back end of the glasses to counterbalance the heavy components at the front end. This counterweight mechanism compensates for the top-heavy design, reducing the skewing and sliding tendency of the glasses during wearing, thereby resolving the contradiction between maintaining front-end functionality and achieving overall balance.
Solution Approach 2:
The patent employs an automatic righting system with air cushions that can dynamically adjust the position of the glasses. When the glasses skew or slide, the air cushions are automatically inflated to push the glasses back to the correct position, providing dynamic stabilization rather than relying solely on static weight distribution.
2Device complexity
If manual adjustment of the glasses is required to correct skewing and sliding, then the glasses structure can be simplified, but the user convenience deteriorates when both hands are occupied
Solution Approach 1:
The patent implements an automatic righting system that detects when the glasses are skewed or slid and automatically corrects the position without user intervention. The system uses distance sensing units to detect position changes and automatically controls air cushions to right the glasses, making the system self-service and eliminating the need for manual adjustment even when hands are occupied.
Solution Approach 2:
The patent incorporates distance sensing units that continuously monitor the position of the glasses relative to the user's face. This feedback mechanism provides real-time information about glasses position to the control system, which then automatically adjusts the air cushions to maintain proper positioning, creating a closed-loop control system that enhances user convenience.
3Ease of operation
If an automatic righting system with distance sensing units and air cushions is implemented, then user convenience is improved, but the device complexity increases
Solution Approach 1:
The patent uses air cushions as the actuating mechanism for the automatic righting system. The air cushions can be quickly inflated and deflated to adjust the glasses position, providing a simple yet effective means of automatic adjustment without requiring complex mechanical structures or motors, thus balancing functionality with relative structural simplicity.
