Wearable Vision Redirection for Ergonomic Magnified Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magnification devices like loupes require users to adopt non-ergonomic postures, leading to strain and fatigue due to the need to bend and tilt their bodies to achieve optimal viewing angles, particularly for professionals requiring prolonged precision work.
Innovation Solution
A wearable optical system with a horizontally positioned display and an imaging modality at a distance from the user's head, which redirects and magnifies the vision through a downward optical path, allowing for ergonomic viewing without bodily contortion, featuring adjustable and retractable supports, image stabilization, and automated or manual movement options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional loupes are used for magnification, then high-quality magnification is achieved, but users must adopt non-ergonomic postures causing strain and fatigue
Solution Approach 1:
The patent positions the imaging modality in a remote location (separate dimension from the user's head) and uses an optical redirecting mechanism to bring the magnified image back to the user's eye. This spatial separation allows the user to maintain an upright, ergonomic posture while still achieving high-quality magnification through the redirected optical path.
Solution Approach 2:
The patent introduces an intermediary optical system consisting of the imaging modality, optical redirecting mechanism, and display device. This intermediary system acts as a mediator between the work area and the user's eye, enabling magnification without requiring the user to contort their body into non-ergonomic positions.
2Ease of operation
If the imaging modality is positioned close to the user's head, then ergonomic viewing is improved, but the optical path and image quality are compromised
Solution Approach 1:
By positioning the imaging modality in a remote location rather than close to the user's head, the patent creates a separate optical dimension. This allows the optical path to be extended and redirected through mirrors or prisms, maintaining image quality while enabling ergonomic viewing distances.
3Device complexity
If the support structure is fixed, then device complexity is reduced, but adaptability to different users and tasks is limited
Solution Approach 1:
The patent incorporates adjustable and retractable support structures that allow the imaging modality to be dynamically repositioned. Users can adjust the position and angle of the imaging modality to suit different tasks and individual preferences, and the retractable feature allows the structure to be collapsed when not in use, balancing adaptability with manageable complexity.
