Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If chemical disinfectants are used to disinfect contact lenses, then the disinfection process is simple and low-cost, but the effectiveness in eliminating microorganisms is insufficient and may cause eye infections

Engineering Contradiction:
Improvedisinfection effectivenessVSAvoiddisinfection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces chemical disinfection with UV radiation disinfection. The UV base unit emits ultraviolet light that penetrates the contact lens case to sterilize lenses without requiring chemical solutions. This substitution achieves superior disinfection effectiveness while maintaining operational simplicity for the user.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a UV base unit as an intermediary disinfection system between lens storage and eye insertion. This intermediary device provides controlled UV exposure to eliminate microorganisms without direct chemical contact with lenses, solving the effectiveness issue while keeping the user interface simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If chemical disinfecting solutions are used, then the initial disinfection cost is low, but the cumulative cost over time is high due to continuous solution purchases

Engineering Contradiction:
Improvemicrobial elimination effectivenessVSAvoiddisinfection solution consumption
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent eliminates the need for continuous purchase of chemical disinfection solutions by using a reusable UV base unit. The UV-C LED or bulb provides ongoing disinfection capability without consumable costs, significantly reducing long-term expenses while maintaining effective microbial elimination.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The UV base unit enables self-service disinfection where the system automatically sterilizes lenses without requiring external chemical solutions. Users simply place lenses in the case, close it, and the UV unit automatically disinfects them, eliminating the need to purchase and manage disinfection solutions.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If traditional chemical disinfection is used, then the process is straightforward, but it fails to eliminate resistant microorganisms like bacteria, viruses, molds, and fungi

Engineering Contradiction:
Improvedisinfection process simplicityVSAvoidcomprehensive microbial elimination
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent changes the disinfection parameter from chemical concentration to UV radiation dose. By controlling UV intensity and exposure time, the system achieves comprehensive microbial elimination across different organism types while maintaining operational simplicity. The UV wavelength and duration are optimized to penetrate lens materials and kill resistant microorganisms.

Inventive Principle:
Principle #35Parameter changes
