Foldable Ophthalmic Apparatus with Chin-Rest for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ophthalmic systems with chin-rests are not foldable, making them bulky and difficult to miniaturize for compact and portable designs, which is essential for storage and transportation.
Innovation Solution
A foldable ophthalmic apparatus with a face-holder that can be folded multiple times, incorporating telescopic legs and a removable chin-rest, allowing for compact storage and transportation, and equipped with diagnostic and therapeutic components for ophthalmic imaging, including OCT imaging, with a focus on human and animal eyes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chin-rest is used to stabilize the patient's eye, then the eye can be stabilized for useful measurements, but the device footprint increases significantly
Solution Approach 1:
The chin-rest is designed to be foldable rather than fixed, allowing it to transition between an extended position during use that provides eye stabilization and a folded position during storage that minimizes device footprint. This dynamic configuration resolves the contradiction between maintaining reliability and reducing stationary area.
2Device complexity
If the chin-rest is made fixed and non-foldable, then the structure is simple and stable, but the device cannot be compacted for portable storage
Solution Approach 1:
The chin-rest incorporates a hinge mechanism that enables it to be folded during storage while remaining stable and simple in structure during use. This dynamic feature adds adaptability for portable storage without significantly complicating the overall structure, as the hinge is a straightforward mechanical addition.
3Volume of stationary object
If the face-holder is made foldable to save storage space, then the device becomes compact and portable, but the structural complexity increases
Solution Approach 1:
The face-holder is designed with a hinge that allows it to fold into a compact configuration for portable storage. While this adds some structural complexity compared to a fixed design, the hinge mechanism is a simple and effective solution that enables the device to transition between extended and folded states, achieving the goal of reduced storage volume.
Solution Approach 2:
The face-holder is divided into segments that can fold relative to each other, with the hinge positioned to allow compact folding. This segmentation enables the structure to be broken down into smaller, more compact portions for storage while maintaining the necessary functionality during use.

AI summary
There is a need for robust and portable system, and apparatus for ophthalmology. We propose use of folding apparatus for ocular purposes for the first time. Our system will have a chin-rest (or face-rest or forehead rest) that can be folded so that the ocular device could be transported in a brief-case type casing.
