AI Technical Summary

Technical Problem

Existing optical assemblies, such as glasses and VR/AR headsets, struggle to adapt to changing focal needs and user eye characteristics due to fixed optical properties, bulkiness, and high power consumption, especially when multiple actuators are required for shape adjustments.

Method used

An optical assembly with an adaptable shape using a single actuator and a combination of transmission assemblies and locking elements, allowing independent movement of contact elements to adjust the lens shape, reducing weight, volume, and power consumption.

Benefits of technology

The solution enables precise and efficient shape adjustments of optical elements using a single actuator, minimizing weight, volume, and power requirements while accommodating various user eye characteristics and focal needs.

Abstract

An optical assembly comprises an optical element having an adaptable shape, a support structure, a first transmission assembly, a second transmission assembly, and an actuator assembly. The support structure defines a first axis. The actuator assembly is configured to exert a force on both the first transmission assembly and the second transmission assembly. The first transmission assembly comprises a first contact element and a first locking element. The second transmission assembly comprises a second contact element and a second locking element.
