Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical devices, such as binoculars and monoculars, cause neck and back strain due to inadequate ergonomic design, variable pupillary distance, and difficulty in adjusting refractive corrections, leading to suboptimal visual experience and long-term health issues for users.
Innovation Solution
A customized viewing system with eyepieces secured to a mask that matches the user's face shape, with lenses positioned at optimal pupillary distance and eye relief, allowing users to rest their head and reducing strain, and optionally incorporating heating elements to prevent condensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional eyepieces with fixed positioning are used, then the optical device can be manufactured simply, but the user experiences neck and back strain due to inability to maintain comfortable head position
Solution Approach 1:
The system performs preliminary measurement of the user's pupillary distance and face geometry before use. These measurements are stored and used to pre-position the optical elements, eliminating the need for manual adjustment during operation and preventing neck strain by ensuring proper ergonomic alignment from the start.
Solution Approach 2:
The system dynamically adjusts optical parameters (lens position, pupillary distance, eye relief) based on stored user measurements. This allows the optical device to adapt to individual user characteristics, providing comfort without requiring complex manual adjustment mechanisms during operation.
2Adaptability or versatility
If adjustable settings are provided for refractive correction, then the optical environment can be customized, but the adjustment becomes difficult or impractical during surgery
Solution Approach 1:
The system pre-determines the optimal optical configuration based on stored user measurements including refractive correction requirements. This eliminates the need for difficult manual adjustments during surgery, as the system is already optimized for the user's specific optical needs before the procedure begins.
Solution Approach 2:
The system automatically maintains optimal optical alignment without requiring user intervention. The optical elements are positioned and adjusted based on pre-stored measurements, allowing the system to serve itself rather than requiring the user to make complex adjustments during surgical procedures.
3Measurement precision
If the user holds head steady in fixed position to find best image, then optimal visual image can be achieved, but neck and back strain occurs
Solution Approach 1:
The system pre-positions the optical elements according to stored user measurements of pupillary distance and face geometry. This ensures that when the user looks through the device, the optical path is already optimized for their anatomy, allowing them to achieve the best image without holding their head in an strained fixed position.
Solution Approach 2:
The system creates an ergonomic equilibrium by aligning the optical axis with the user's natural head position based on their measurements. This eliminates the need to hold the head in an unnatural fixed position, as the system is designed to work comfortably with the user's natural posture, balancing visual quality with physical comfort.
4Measurement precision
If eyepieces are configured for optimal optical performance, then image quality improves, but the design does not allow user's head to rest on them
Solution Approach 1:
The system transitions from traditional eyepiece design to a mask-based interface that contacts the user's face across a larger surface area. This dimensional change from point-contact eyepieces to distributed facial contact allows the user's head to rest comfortably on the mask while maintaining precise optical alignment through the positioned lenses.
Solution Approach 2:
The system changes the geometric parameters of the interface between the optical device and the user. By using a mask that conforms to facial geometry and distributes contact points, the system maintains optimal optical performance while enabling head support, resolving the contradiction between image quality and comfort.
