Stackable Eye Shields With Elevated Support Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eye shields are difficult to stack and dispense due to entanglement and shifting, requiring users to handle multiple shields at once.
Innovation Solution
The eye shields feature elevated support surfaces on their frames, allowing them to be stacked parallel to each other with slight forward offset, preventing entanglement and shifting, and a specially designed container facilitates easy access and dispensing.

Engineering Contradiction Analysis
1Productivity
If conventional eye shields are stacked in boxes, then shipping and dispensing can be facilitated, but the eye shields become entangled and shifted and become difficult to dispense
Solution Approach 1:
The frame includes elevated portions at specific locations (temple pieces and brow piece) that create localized contact points with adjacent eye shields. These elevated portions are strategically positioned to provide stable stacking without requiring the entire frame surface to be elevated, thus preventing entanglement while maintaining ease of dispensing.
Solution Approach 2:
The frame transitions from a conventional flat two-dimensional structure to a three-dimensional structure with elevated portions that protrude upward. This dimensional change creates vertical separation and stable contact points between stacked eye shields, preventing horizontal shifting and entanglement while maintaining easy access to individual shields.
2Volume of stationary object
If eye shields are stacked one on top of another, then shipping space is optimized, but the shields become entangled and require handling of multiple shields
Solution Approach 1:
Rather than elevating the entire frame, only specific localized portions (temple pieces and brow piece) are elevated to create precise contact points. This localized approach maintains compact stacking for space efficiency while preventing the kind of widespread entanglement that would require handling multiple shields.
Solution Approach 2:
The frame's elevated portions are segmented into distinct locations (brow piece and temple pieces) rather than being a continuous elevated structure. This segmentation allows for optimized contact points that prevent entanglement between shields while maintaining compact vertical stacking, enabling single-shield removal without handling others.
3Stability of the object's composition
If eye shields have elevated support surfaces, then stacking stability is improved, but the frame structure becomes more complex
Solution Approach 1:
The elevated portions are integrated into existing frame components (temple pieces and brow piece) rather than adding separate complex structures. This localized modification provides stable stacking contact points while minimizing overall structural complexity and maintaining manufacturing simplicity.
Solution Approach 2:
The elevated portions of the frame serve multiple functions: they provide structural support for the lens, enable stable stacking contact with adjacent shields, and maintain the aesthetic design of the eyewear. This multi-functionality reduces the need for additional complex components.

AI summary
A container having a stack of eye shields, includes a stack of eye shields having a plurality of eye shields stacked one on top of another. The stack of eye shields is in a sloped configuration in which ear pieces of frames of the eye shields are generally aligned with one another and disposed at an angle relative to horizontal of from about 10 to about 35 degrees. A container is provided having a horizontal bottom onto which the stack of eye shields is supported, the container having a top opposite the bottom, the top being sloped to be substantially parallel to the ear pieces of the eye shields of the stack of eye shields.
