Contact Lens Package Ganging via Lugs and Overhangs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contact lens packages are not optimized for easy storage, display, and access, particularly for disposable lenses, as they are often bulky and require separate packaging, which complicates consumer use and retail display.
Innovation Solution
A contact lens package design that allows multiple units to be conjoined via lugs and lug receptacles, forming a 'ganged' grouping for storage and display, with a base and lid configuration that maintains a compact profile and easy access to lenses and solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact lens packages are packaged and stored separately in individual blister packs, then each package provides secure storage and shipping, but the packages become bulky and require more storage space
Solution Approach 1:
The patent combines multiple individual contact lens packages into a single multi-well blister pack. Each well contains a contact lens with storage solution, and all wells are sealed within one common lid, merging the function of multiple separate packages into one unified structure that reduces storage volume while maintaining security.
Solution Approach 2:
The common lid serves multiple functions: it seals multiple individual wells simultaneously, provides a unified protective cover for all lenses, and enables the entire assembly to be treated as a single unit for storage and shipping, thereby reducing the overall volume required.
2Ease of manufacture
If contact lens packages are packaged separately in individual blister packs, then each package is simple to manufacture, but retail display and consumer selection become more complex
Solution Approach 1:
Multiple contact lens packages are merged into a single blister pack with multiple wells, allowing retailers to display multiple lens options in one compact unit rather than managing numerous separate packages, thereby simplifying retail display and consumer selection.
3Volume of stationary object
If contact lens packages are made smaller for easy storage, then portability is improved, but access to multiple lenses becomes more difficult
Solution Approach 1:
The blister pack is segmented into multiple independent wells, each containing a contact lens with its own storage solution. This segmentation allows consumers to access individual lenses easily by opening only the specific well needed, while the entire assembly remains compact for portability.
Solution Approach 2:
Multiple lenses are combined in one compact blister pack with individual wells, providing both easy access to specific lenses and convenient portability as a single unit.

AI summary
A contact lens package has a body with a lens receptacle therein covered by a hinged lid. The lid is offset on the body such that a ledge is formed by the base and an overhang by the lid. The ledge has a plurality of upstanding lugs that insert into mating receptacles formed in the overhang of an adjacent contact lens package, permitting the ganging of packages together for functional and aesthetic reasons.
