Single Display Module AR Glasses for Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality glasses face challenges with increased weight and current consumption due to the use of two display modules for binocular mode, limited flexibility in switching between monocular and binocular modes, and inability to meet user requirements for wide field of view and dual monitor usage.
Innovation Solution
An electronic device with a single display module positioned at the nose support, utilizing an optical system to transfer the screen to both eyes and a control unit to adjust the aspect ratio and mode selection, allowing for selective operation in monocular or binocular modes, reducing weight and current consumption while increasing battery use time and supporting wide field of view requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two display modules are used for binocular mode, then the augmented reality function is improved, but the weight and current consumption increase
Solution Approach 1:
A single display module is designed to perform both monocular and binocular display functions. The control unit enables the display module to operate in different modes (monocular or binocular) based on user selection, making one component serve multiple purposes and eliminating the need for separate display modules for each mode.
Solution Approach 2:
The patent combines the functions of two separate display modules into one unified display module. By merging the display functionality and controlling it through a single control unit, the system achieves binocular mode capability without duplicating the entire display module, thereby reducing weight and component count.
2Adaptability or versatility
If two display modules are used for binocular mode, then the augmented reality function is improved, but the current consumption increases
Solution Approach 1:
A single display module is designed to perform both monocular and binocular display functions. The control unit enables the display module to operate in different modes (monocular or binocular) based on user selection, making one component serve multiple purposes and eliminating the need for separate display modules for each mode.

3Weight of moving object
If a single display module is used, then the weight and current consumption are reduced, but the binocular mode capability is lost
Solution Approach 1:
The display module's operational mode is made dynamic and adjustable rather than fixed. The control unit allows the system to switch between monocular and binocular modes based on user preference or environmental conditions, enabling a single module to adapt its functionality to meet different requirements.
Solution Approach 2:
A single display module is designed to perform both monocular and binocular display functions. The control unit enables the display module to operate in different modes (monocular or binocular) based on user selection, making one component serve multiple purposes and eliminating the need for separate display modules for each mode.
4Adaptability or versatility
If the aspect ratio is increased for wide field of view, then the user experience is improved, but the display module size increases
Solution Approach 1:
The aspect ratio of the display module is optimized to provide a wide field of view while controlling the physical size. By carefully selecting and adjusting the aspect ratio parameter, the system achieves improved user experience for wide field of view applications without proportionally increasing the display module's physical dimensions.
