Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user carries traditional contact lens cleaning supplies (water, separate cleaning products), then cleaning effectiveness is improved, but portability and convenience deteriorate
Solution Approach 1:
The patent combines multiple cleaning functions (hand cleaning, lens cleaning, and lens rinsing) into a single portable device. The first compartment contains a wipe for hand cleaning, while the second compartment contains cleansing solution for lens cleaning and rinsing. This merging of functions eliminates the need to carry separate water bottles, cleaning solutions, and wipes, thereby improving portability while maintaining cleaning effectiveness.
Solution Approach 2:
The cleansing solution in the second compartment serves multiple purposes: it cleans the contact lenses, rinses them, and provides therapeutic benefits through Euphrasia. The single device thus performs hand sanitation, lens cleaning, lens rinsing, and lens treatment, making it a universal solution for contact lens care on the go.
2Ease of operation
If a user cleans contact lenses without proper supplies (when away from home), then convenience is improved, but cleaning quality and hygiene deteriorate
Solution Approach 1:
The device is prepared in advance with pre-packaged wipes in the first compartment and pre-measured cleansing solution with Euphrasia in the second compartment. This preliminary preparation ensures that when the user needs to clean their lenses away from home, they have all necessary supplies ready to maintain proper cleaning quality and hygiene without needing to find water or other supplies.
Solution Approach 2:
The device uses disposable wipes in the first compartment and a single-use quantity of cleansing solution in the second compartment. This disposable approach ensures hygiene by preventing cross-contamination when used away from home, while the compact single-use format maintains convenience. The wipe is discarded after hand cleaning, and the cleansing solution is used once for lens cleaning and rinsing.
3Ease of operation
If a compact portable device is used, then portability is improved, but cleaning solution volume and treatment effectiveness deteriorate
Solution Approach 1:
The cleansing solution uses Euphrasia at a concentration of 1.0 mg/mL, which provides therapeutic effectiveness in a small volume. The concentrated formulation allows sufficient cleaning and treatment of contact lenses in a compact portable device without requiring large quantities of solution. The specific concentration parameter ensures effectiveness while maintaining portability.
