Adjustable Display Actuator for Head-Mounted Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mountable electronic devices lack adjustable displays relative to the user's eyes, which can lead to discomfort and reduced usability due to fixed display positions.
Innovation Solution
Incorporating actuators, such as motors or manual dials, to adjust the distance and angle of the display relative to the user's eyes, allowing for customizable positioning based on user preferences, activities, and body positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed display position is used in head-mountable devices, then the device structure is simple, but user comfort and usability are reduced due to inability to accommodate varying facial features and preferences
Solution Approach 1:
The patent implements adjustable display positioning mechanisms that allow the display unit to move relative to the user's eyes. This includes motorized actuators that can dynamically change the distance between the display and the user's eyes, transforming the fixed display position into a dynamic, adjustable configuration to accommodate different facial features and user preferences
Solution Approach 2:
The patent changes the positional parameters of the display unit by introducing adjustment mechanisms that modify the distance and angle between the display and the user's eyes. This allows the system to adapt to varying facial dimensions and user comfort requirements by changing key geometric parameters of the display configuration
2Adaptability or versatility
If an adjustable display mechanism is added to head-mountable devices, then user comfort and adaptability are improved, but the device complexity and structural components increase
Solution Approach 1:
The patent divides the head-mountable device into separate adjustable components, including a display unit, frame, and actuator mechanisms. This segmentation allows each component to be independently optimized and adjusted, providing flexibility in display positioning while maintaining modularity in the overall device structure
Solution Approach 2:
The patent designs the adjustable display mechanism to serve multiple functions: accommodating different facial sizes, adjusting for user preference, compensating for different activities and body positions, and maintaining proper display alignment. This multi-functionality justifies the added complexity by providing comprehensive adaptability
3Ease of operation
If manual actuators like dials are used for display adjustment, then the device structure is simpler, but the ease of operation and precision of adjustment are reduced
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with motorized actuators that can be controlled electronically. This substitution improves ease of operation by allowing precise adjustment through electronic control rather than manual manipulation, and enables automated positioning based on sensor feedback or user input
4Adaptability or versatility
If the display distance is made adjustable to accommodate different activities and body positions, then adaptability is improved, but the device complexity and energy consumption increase
Solution Approach 1:
The patent implements adjustment mechanisms that operate periodically or on-demand based on detected changes in activity level or body position, rather than continuously. This allows the display to be repositioned when needed while minimizing energy consumption during stable conditions

AI summary
Head-mountable electronic devices including adjustable displays and methods of using the same are disclosed. In an example, a head-mountable electronic device includes a display unit including a display, a first frame coupled to the display, a second frame coupled to the first frame by a first actuator, and a securement strap coupled to the second frame. The first actuator can be configured to adjust a distance between the first frame and the second frame, and the first actuator can be non-backdrivable.
