Spectacle Optical Display Layout for Unobstructed Direct Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical display systems integrated into spectacles are bulky and obstructive, failing to optimize the size, weight, and design of common spectacles while allowing unobstructed viewing of the environment.
Innovation Solution
A spectacle system with an optical unit featuring an emitting module and a geometric reflection element positioned at opposite internal edges of the frame, utilizing the space near the nose joint to minimize bulk and obstruction, and incorporating optical transformation elements to project images onto the rear diopter without obstructing direct vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display system is positioned horizontally over the bridge of the nose, then the display function is achieved, but the spectacles become incompatible with common spectacles and obstruct the view of the environment
Solution Approach 1:
The patent repositions the display system from a horizontal arrangement over the bridge of the nose to a vertical arrangement along the lateral edge of the spectacle lens. This dimensional change allows the display elements to be positioned at the periphery, eliminating obstruction of the central environmental view while maintaining display functionality.
Solution Approach 2:
The patent positions different functional elements at specific locations: the emitting module is placed at one lateral edge while the reflection element is placed at the opposite lateral edge. This localized distribution optimizes each element's position to minimize overall obstruction and maintain compatibility with common spectacles.
2Adaptability or versatility
If the optical system is designed to project images into the user's eye, then the display function is achieved, but the space occupied by the optical system increases
Solution Approach 1:
The patent extracts the display function from the central optical path and positions it at the lateral edges of the spectacle lenses. By separating the emitting module and reflection element to opposite edges, the system minimizes the space occupied in the central viewing area while maintaining display capability.
3Adaptability or versatility
If the display is positioned at the upper edge of the spectacle lens, then the display function is achieved, but the system becomes bulky and requires significant eye movement
Solution Approach 1:
The patent employs asymmetric positioning where the emitting module and reflection element are placed at opposite lateral edges rather than symmetrically at the upper edge. This asymmetric arrangement creates a more efficient optical path that reduces the angular deviation required for image projection, thereby reducing eye movement requirements.
