Temple Connecting Structure for Head-Mounted Display Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current head-mounted display devices, such as AR, VR, and MR glasses, use a simple hinge structure for temple connection, leading to instability and a higher likelihood of accidental falling off, especially for users with smaller head sizes.
Innovation Solution
A temple connecting structure featuring a base, rotatably connected mounting brackets, and clamping elastic members, such as torsion springs, that apply a clamping force to the mounting brackets, allowing the glass frame and temples to move closer together, enhancing stability and fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple hinge structure is used for temple connection, then the device complexity is reduced and manufacturing is easier, but the wearing stability deteriorates and the device may fall off
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotatable mounting bracket that can dynamically adjust between folded and unfolded positions. The bracket rotates around a rotation axis, allowing the temple to transition from a compact folded state to an extended wearing state, providing adaptability to different head sizes while maintaining structural reliability
Solution Approach 2:
The connection structure is segmented into distinct functional components: a base, a rotatable mounting bracket, and a temple. This segmentation allows each component to perform its specific function independently - the base provides support, the bracket enables rotation and adjustment, and the temple fits the ear - thereby improving overall wearing stability through specialized functional design
2Device complexity
If a simple hinge structure is used for temple connection, then the device structure is simpler, but the adaptability to different head sizes deteriorates
Solution Approach 1:
The mounting bracket is designed to rotate dynamically between folded and unfolded positions, enabling the device to adapt to different head circumferences. When unfolded, the temple extends to accommodate larger head sizes; when folded, it compactes for smaller heads, providing versatility without requiring multiple device variants
Solution Approach 2:
The rotation mechanism is pre-configured with a rotation axis and appropriate clearance, allowing the mounting bracket to be preliminarily positioned in either folded or unfolded state before actual wearing. This preliminary configurability enables users to adjust the device to their head size before putting it on, enhancing adaptability
