Solution Overview
Problem
Existing glass-type electronic devices fail to achieve lightweight and transverse balance, obstruct the user's field of view, and cause image distortion, which are essential for augmented reality applications.
Innovation Solution
The design includes a binocular lens with an optical driving assembly positioned between the superciliary arches, a support member with an elastic material, and a battery placement that minimizes weight and obstruction, ensuring clear image transmission without distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the electronic component case is positioned between superciliary arches, then weight distribution and balance are improved, but the device complexity increases
Solution Approach 1:
The electronic component case is repositioned from conventional lateral placement to a vertical dimension between the superciliary arches (eyebrows), utilizing the previously underutilized space above the eyes. This spatial reconfiguration achieves better weight distribution and balance without adding components, effectively resolving the contradiction between weight optimization and device complexity.
2Object-affected harmful factors
If the optical driving assembly is positioned between superciliary arches, then field of view obstruction is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The optical driving assembly is relocated to the vertical space between superciliary arches, moving it out of the horizontal field of view path. This dimensional relocation eliminates field of view obstruction while the integrated support member structure provides inherent positioning guidance, managing the precision requirements through structural design rather than tightening manufacturing tolerances.
Solution Approach 2:
A support member is introduced as an intermediary element that connects the optical driving assembly to the lens frame. This support member serves as a positioning mediator that guides the assembly during installation and maintains precise positioning during use, thereby reducing the direct precision requirements between the optical assembly and the lens frame.
3Stability of the object's composition
If the battery is positioned in the upper portion of the electronic component case, then transverse balance is improved, but the device complexity increases
Solution Approach 1:
The battery is strategically positioned in the upper portion of the electronic component case to act as a counterweight, balancing the weight distribution across the device. This counterbalancing arrangement achieves transverse balance without requiring additional counterweights or complex balancing mechanisms, resolving the contradiction by using the existing battery as the balancing element.
4Ease of operation
If the lens frame is designed to be seated on the head, then mobility is improved, but image distortion occurs
Solution Approach 1:
A support member is introduced as an intermediary between the optical driving assembly and the lens frame. This support member provides a stable mounting interface that maintains precise optical alignment even when the device moves on the user's head, thereby preserving image quality while allowing mobility. The support member acts as a reference frame that compensates for head movements.
