Resealable Contact Lens Case with Removable Inner Pod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contact lens cases are prone to microbial contamination due to non-sterile conditions and lack of versatility in using different lens care solutions, leading to cross-contamination issues.
Innovation Solution
A re-sealable contact lens case design featuring a removable inner pod with a re-sealable lid, allowing easy switching between different solutions without cross-contamination, and a mechanism for ensuring a water-tight seal to prevent leakage during transportation and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a rigid plastic case with screw-top lids is used for storing contact lenses, then the case can be reused multiple times, but the case is prone to microbial accumulation due to non-sterile conditions
Solution Approach 1:
The case is divided into separate compartments (first compartment and second compartment) that are isolated from each other by a partition. Each compartment can be independently sealed with its own lid, allowing one compartment to be sterilized or replaced without affecting the other. This segmentation prevents cross-contamination and allows selective sterilization to maintain hygiene while preserving reusability.
Solution Approach 2:
The invention allows for the replacement of individual compartments or lids rather than requiring complete case replacement when contamination occurs. The removable and replaceable nature of components enables users to discard contaminated parts and replace them with sterile ones, maintaining the overall case structure and its reusability while eliminating microbial contamination risks.
2Device complexity
If a single well case with screw-cap lid is used, then the case structure is simple, but cross-contamination occurs when switching between different lens care solutions
Solution Approach 1:
The case is divided into multiple independent compartments separated by a partition, with each compartment having its own lid. This allows users to store different lens care solutions in separate compartments without cross-contamination, while maintaining a relatively simple overall case structure. Each compartment can be independently accessed and sealed.
Solution Approach 2:
The case design with multiple compartments and replaceable lids provides universal functionality for storing various types of lens care solutions (cleaning solution, disinfecting solution, storage solution) in a single case structure. The standardized compartment design allows flexibility in using different solutions while preventing cross-contamination between them.
3Ease of operation
If lenses are completely submerged in solution in a single well case, then the lenses are held in solution, but the case is still prone to contamination during re-use
Solution Approach 1:
The case is divided into separate compartments, each capable of holding lenses completely submerged in solution. The partition between compartments prevents cross-contamination when multiple solutions are used. Each compartment can be independently sealed with its own lid, maintaining hygiene while preserving the submersion capability for lens care.

AI summary
A case (1) is provided for holding one or more contact lenses, configured to receive an inner pod (not shown). The case includes an upper (7) and a lower part (9). The upper part is structured to move relative to the lower part from an open configuration to a closed configuration and from a disengaged position to an engaged position wherein, in the disengaged position, the case is movable between the open and closed configurations and in the engaged position, the case is locked in the closed configuration.
