Adjustable Eyeglass-Mounted Viewer for Endoscopic Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglass-mounted image display devices lack adaptability, as they do not allow adjustable intervals, heights, or angles of viewers, leading to the need for operator-specific devices, increased costs, and potential visual field obstruction during endoscopic surgery.
Innovation Solution
An eyeglass-mounted image display device with detachably attached viewers that are adjustable in interval, height, and elevation/depression angle, positioned in front of lenses to avoid lens processing and ensure a wider visual field, and equipped with a detachable attaching mechanism for strabismic operators, allowing multiple operators to share the device and individually control image brightness and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If viewers are fixed on eyeglasses with openings in lenses, then the device structure is simple, but the visual field is narrowed and scattered objects may enter during surgery
Solution Approach 1:
The invention removes the openings from the lenses entirely, extracting the harmful element that causes visual field obstruction and scattered object entry. The viewers are positioned in front of the lenses without requiring any openings, thus eliminating the harmful effect while maintaining the display function.
Solution Approach 2:
The viewers are repositioned from being integrated within the lens structure to being positioned in front of the lenses in a separate spatial dimension. This dimensional change allows the viewers to be attached to the eyeglass frame rather than requiring lens openings, thereby expanding the visual field while maintaining device functionality.
2Device complexity
If viewers are fixed at a fixed position on eyeglasses, then the device structure is simple, but the device lacks adaptability for different operators
Solution Approach 1:
The invention introduces adjustable mechanisms that allow the viewers to be dynamically repositioned in terms of interval, height, and elevation/depression angle. This transforms a static fixed-position structure into a dynamic adjustable one, enabling adaptation to different operators' anatomical variations while maintaining reasonable structural complexity through standardized adjustment mechanisms.
Solution Approach 2:
The invention creates a universal device that can serve multiple operators with different facial geometries and viewing requirements. Through the adjustable mechanisms, a single device configuration can be adapted to fit various operators, eliminating the need for operator-specific custom devices and thereby achieving versatility without proportionally increasing overall device complexity.
3Adaptability or versatility
If operator-specific image display devices are made, then the adaptability for different operators is improved, but the cost increases
Solution Approach 1:
The invention designs a universal adjustable device that can serve multiple operators, eliminating the need to manufacture separate operator-specific devices. The adjustment mechanisms allow a single standardized device to be configured for different operators, thereby reducing the quantity of devices needed and lowering overall costs while maintaining high adaptability.
Solution Approach 2:
The invention enables adaptation to different operators by adjusting parameters such as viewer interval, height, and elevation/depression angle, rather than manufacturing different devices for each operator. This parameter-based customization approach allows a single device to serve multiple operators with different anatomical characteristics, significantly reducing costs while maintaining operator-specific fit and comfort.
