Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contact lens cases are bulky, making them inconvenient to carry and prone to being forgotten or misplaced during travel.
Innovation Solution
A slim contact lens case with a compact design featuring parallel upper and lower surfaces, gaskets for sealing, and a through-hole for attachment to a keyring, allowing for easy carrying in wallets or bags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard contact lens case with two caps is used, then contact lenses can be securely stored, but the case becomes bulky and inconvenient to carry
Solution Approach 1:
The case is divided into two separate lids (first lid and second lid) that can be independently opened and closed, allowing users to access one contact lens without disturbing the other. This segmentation enables a more compact overall structure while maintaining secure storage for both lenses.
Solution Approach 2:
The patent transitions from a traditional wide, shallow case design to a slim, depth-oriented design by reducing the horizontal footprint and increasing vertical efficiency. The parallel upper and lower surfaces create a streamlined profile that fits more easily in pockets and bags.
2Reliability
If caps are screwed or snapped onto housing units, then solution leakage is prevented, but the case structure becomes more complex and bulky
Solution Approach 1:
The sealing function is merged into the lid structure itself through integrated gaskets rather than requiring separate cap mechanisms. The first gasket and second gasket are positioned within channels on the lids, combining the closure and sealing functions into a single component system.
Solution Approach 2:
Gaskets are used to create flexible sealing barriers within channels on the lids. These thin film elements conform to the housing contours and prevent solution leakage without requiring rigid, bulky cap structures.
3Volume of moving object
If a slim design with parallel surfaces is used, then portability is improved, but sealing reliability may be compromised
Solution Approach 1:
The lids feature localized sealing channels with gaskets positioned at critical sealing points rather than requiring uniform thickness throughout the entire structure. This allows the case to be slim overall while maintaining robust sealing where needed.
Solution Approach 2:
The gaskets are nested within channels on the lids, creating a layered sealing structure. The first channel receives the first gasket, and the second channel receives the second gasket, allowing effective sealing within a compact thickness.

AI summary
A contact lens case includes a body having a first upper surface, a bottom surface and a sidewall therebetween. The body defines a first recessed well configured to receive a first contact lens therein and a second recessed well configured to receive a second contact lens therein. A first cap is removably coupled with the body to selectively cover the first recessed well when in a closed position. The first cap includes a second upper surface such that the body is flush with the first cap when the first cap is in the closed position. A second cap is removably coupled with the body to selectively cover the second recessed well when in a closed position. The second cap includes a third upper surface such that the body is flush with the second cap when the second cap is in the closed position.
