Wearable Frame Reinforcement for AR Sensor Stability and Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted wearable devices, such as AR glasses, face challenges in maintaining sensor accuracy due to inflexible frames that cause discomfort when worn, and there is a need to distribute weight evenly to prevent force concentration at the center of gravity.
Innovation Solution
A wearable electronic device design incorporating a reinforcing member to enhance the rigidity of the front surface, coupled with a hinge structure and flexible temples to mitigate discomfort and improve sensor accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the frame is made rigid to support sensors on the front surface, then sensor position stability is improved, but wearing comfort deteriorates due to inflexibility
Solution Approach 1:
The frame is divided into a front frame portion and a rear frame portion connected by a hinge structure. The front frame portion maintains rigidity for sensor stability, while the rear frame portion with hinge structure provides flexibility for wearing comfort. This segmentation allows each part to fulfill its specific function without compromise.
Solution Approach 2:
Different portions of the frame have different rigidity characteristics. The front frame portion where sensors are mounted maintains high rigidity for accurate recognition, while the rear frame portion and hinge structure have lower rigidity to provide flexibility and comfort during wearing. This local differentiation resolves the contradiction between overall rigidity and flexibility.
2Ease of operation
If the frame structure is made flexible to improve wearing comfort, then ease of operation is improved, but sensor position stability deteriorates
Solution Approach 1:
The frame is segmented into front and rear portions with different structural characteristics. The front frame portion is designed with high rigidity to stabilize sensors, while the rear portion incorporates hinge structures for flexibility. This segmentation ensures sensor stability is not compromised by the flexible rear portion.
3Stability of the object's composition
If weight is concentrated at the center of gravity, then structural stability is improved, but wearing comfort deteriorates due to force concentration
Solution Approach 1:
The heavy battery component is extracted from the center of gravity position and relocated to the rear frame portion. This extraction prevents force concentration at the center of gravity, improving wearing comfort while the rear frame portion's structure maintains overall structural stability.
