Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional head-mounted electronic devices provide a viewing angle of 100 to 120 degrees, which is narrower than the human visual field of 200 degrees, limiting the immersion and comfort when experiencing high-level applications like video images and 3D content, as users feel like they are viewing through a periscope.
Innovation Solution
A head-mounted electronic device with a curved display and a frame having a mounting surface with a curvature, featuring a pair of optical assemblies with a first lens forming a binocular visual field and a second lens inclined to form an additional peripheral visual field, achieving an ultra-wide viewing angle of 180 degrees while maintaining a slim and lightweight design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display and optic size are increased to implement an ultra-wide angle of 180 degrees, then the viewing angle is improved, but the device size and weight are increased
Solution Approach 1:
The optical assembly is divided into multiple lenses: a first lens for the binocular visual field and a second lens for the peripheral visual field. This segmentation allows each lens to be optimized for its specific function, achieving a wide 180-degree viewing angle while keeping individual lens sizes small and the overall device lightweight.
Solution Approach 2:
The second lens is arranged to slope at a predetermined angle relative to the first lens, utilizing three-dimensional spatial arrangement. This angular configuration enables the peripheral visual field to be captured without increasing the linear dimensions of the device, maintaining a compact form factor while achieving ultra-wide viewing coverage.
