Wearable Optical Display Glabellar Positioning Unobstructed View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable optical display systems obstruct the user's field of regard (FOR) by positioning optical elements in front of the eyes, which can compromise safety and usability in dynamic environments, and often fail to meet civilian safety standards due to bulkiness and weight.
Innovation Solution
A user wearable optical display system featuring a partially transmissive partially reflective lens and an electro-optical unit positioned at the glabellar region, allowing for unobstructed viewing while projecting light-encoded data onto the lens, which is designed to be shatter-resistant and comply with safety standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If optical elements are positioned in front of the eyes in existing wearable optical display systems, then information can be displayed to the user, but the user's field of regard is obstructed
Solution Approach 1:
The patent relocates the electro-optical unit from the traditional position in front of the eyes to the glabellar region (between the eyebrows), utilizing a different spatial dimension on the user's head. This dimensional repositioning allows the optical elements to project images onto the user's field of regard without physically blocking the user's view of the surrounding environment, thereby resolving the contradiction between information display capability and field of regard obstruction
2Adaptability or versatility
If existing wearable optical display systems are designed to be compact, then they may meet safety standards, but they often fail to meet civilian safety standards due to bulkiness and weight
Solution Approach 1:
The patent divides the wearable optical display system into separable components: a lightweight frame structure and a detachable electro-optical unit. This segmentation allows the main body to remain compact and lightweight for normal use, while the electro-optical unit can be removed or adjusted when not needed, enabling the system to meet civilian safety standards without requiring the entire assembly to be perpetually compact
Solution Approach 2:
The patent employs a detachable mounting mechanism that allows the electro-optical unit to be dynamically attached or removed from the frame. This dynamic configuration enables the system to adapt between a complete assembly for functionality and a reduced assembly for safety compliance, resolving the contradiction between adaptability to safety standards and device weight
3Reliability
If existing wearable optical display systems use traditional positioning, then optical elements can function, but safety is compromised in dynamic environments
Solution Approach 1:
The patent extracts the electro-optical unit from the critical viewing area in front of the eyes and relocates it to the glabellar region. This extraction removes the source of potential safety hazards from the dynamic environment near the user's face, while the optical functionality is preserved through the projection mechanism that directs images onto the user's field of regard without requiring physical presence in the hazardous zone
