Detachable Chin Rest for Ophthalmologic Apparatus Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmologic apparatuses lack sufficient support for the chin, leading to instability and discomfort for examinees during eye examinations, which can result in inaccurate and inefficient data acquisition.
Innovation Solution
A detachable chin rest device designed to be attached to an optical table or pedestal of an ophthalmologic apparatus, featuring a chin rest portion that extends to support the chin of the examinee, allowing for stable face support and adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a chin rest device is added to support the examinee's chin, then face support stability is improved, but device complexity increases
Solution Approach 1:
The chin rest device is designed as a separate, detachable unit that can be independently attached to the optical table or pedestal. This segmentation allows the chin rest functionality to be added without redesigning the entire ophthalmologic apparatus, thus improving face support stability while minimizing the increase in overall device complexity.
Solution Approach 2:
The chin rest device is designed to be universally compatible with different ophthalmologic apparatus configurations by providing attachment mechanisms that can be mounted on either an optical table or a pedestal. This multi-functionality allows the same chin rest device to serve multiple purposes and work with various system architectures.
2Ease of operation
If the chin rest device is made detachable for easy attachment and detachment, then ease of operation is improved, but reliability may worsen
Solution Approach 1:
The attachment mechanism is designed to be dynamically adjustable, allowing easy attachment and detachment when needed, while providing sufficient securing force when attached. The mechanism transitions between a easily engaged/disengaged state and a stable, reliable attached state, balancing ease of operation with attachment reliability.
