Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable optical display systems obstruct the user's field of regard by positioning functional 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 with 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, featuring a compact and lightweight design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If functional elements are positioned in front of the eyes in existing wearable optical display systems, then the display function is achieved, but the user's field of regard is obstructed and safety is compromised
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 relocation allows the display components to be positioned above the field of regard rather than within it, eliminating obstruction while maintaining display functionality through the partially transmissive partially reflective lens.
2Reliability
If existing wearable optical display systems are designed with sufficient protective features, then safety standards may be met, but the device becomes bulky and heavy
Solution Approach 1:
The patent employs a thin, partially transmissive partially reflective lens that provides the necessary protective and optical functions without the bulk of traditional display components. This thin-film approach allows the lens to serve multiple functions including display, protection, and optical transmission while maintaining a lightweight profile that meets civilian safety standards without excessive weight.
3Ease of operation
If existing wearable optical display systems use traditional display components, then display capability is achieved, but the device becomes bulky and does not meet civilian safety standards
Solution Approach 1:
The partially transmissive partially reflective lens functions as a thin-film display component that replaces bulky traditional display hardware. This thin-film technology enables display capability while minimizing the physical footprint and bulk of the device, allowing it to meet civilian safety standards for wearable optics.
Solution Approach 2:
By positioning the electro-optical unit in the glabellar region and using the lens as both display and protective element, the patent eliminates the need for bulky display components in front of the eyes. The spatial reconfiguration allows display functionality to be achieved with minimal device bulk.
