AR Wearable Mirror Light Path Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional AR wearable electronic devices face issues with light interference from projectors with users' bodies and limited angle of view, as well as storage convenience when temples are folded.
Innovation Solution
A wearable electronic device design featuring a frame with window members, leg members, and a mirror member that reflects light from the display module to the window members, allowing for interference-free light distribution and easy storage by rotating the leg members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the projector is disposed at both sides of the device (between user's eyes and ears), then the device structure is simple, but light emitted from the projector interferes with the user's body
Solution Approach 1:
The projector is extracted from the conventional position at both sides of the device and relocated to the center of the frame. This extraction from the harmful position eliminates light interference with the user's body while maintaining the device's structural simplicity
Solution Approach 2:
A reflection member is introduced as an intermediary component between the centrally-positioned projector and the window members. This mediator redirects the light path using reflection, allowing the projector to be centrally located without causing light interference to the user's body
2Object-affected harmful factors
If the projector is placed close to the lens to avoid light interference, then light interference is reduced, but the angle of view is limited
Solution Approach 1:
The light path is extended into a different spatial dimension by using a reflection member to redirect light. This allows the projector to be positioned closer to the lens (reducing light interference) while the reflected light path maintains or enhances the angle of view through optimized optical geometry
3Ease of operation
If the temples are folded for storage, then storage convenience is improved, but interference is caused when folding
Solution Approach 1:
The device is segmented into modular components including the frame, window members, and leg members that can be independently positioned. This segmentation allows the leg members to be rotated and folded without interfering with other components, improving storage convenience while eliminating folding interference
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution prevents light interference with the user's body, enhances the angle of view, and facilitates easy storage by reducing the device's volume when folded, while maintaining a compact form for AR functionality.
Implementation Method 1
at least one mirror member configured to reflect light emitted from the at least one display module and cause the emitted light to reach at least one of the pair of window members
