Solution Overview

Problem

Existing contact lens cleaning devices are noisy, bulky, require external components, and often fail to effectively clean and disinfect lenses due to exposure to dirt and foreign particles, with no option to set different cleaning modes.

Innovation Solution

A compact, standalone vibrating base assembly with integrated vibration motors and polymeric components that supports contact lens containers, offering two cleaning modes and reducing noise, with no need for external components, designed to minimize lens exposure to contaminants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If existing vibrating cleaning devices are used, then contact lenses can be cleaned, but excessive noise is generated which is inconvenient and bothersome to users

Engineering Contradiction:
ImprovenoiseVSAvoidcleaning effectiveness
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent replaces traditional mechanical vibrating mechanisms with ultrasonic vibration technology. The ultrasonic cleaner uses high-frequency ultrasonic waves (20kHz-100kHz) to generate cavitation bubbles in the cleaning solution, which collapse and create micro-jets that remove deposits from lenses. This substitution eliminates the need for loud mechanical motors while maintaining effective cleaning through acoustic energy.

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

Solution Approach 2:

The patent employs a liquid cleaning solution (hydraulic medium) that fills the cleaning chamber and interacts with ultrasonic waves to produce cavitation effects. The liquid medium transmits ultrasonic energy efficiently and enables the cavitation process that removes protein and residue buildup from lenses without requiring direct mechanical contact or loud vibrating motors.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If contact lenses are placed directly within the cleaning device, then cleaning can occur, but lenses are exposed to dirt, dust, rust, germs, residue from prior uses, and other foreign particles resident on the cleaning device

Engineering Contradiction:
Improvedisinfection effectivenessVSAvoidexposure to contaminants
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a liquid cleaning solution as an intermediary between the lenses and the cleaning device surfaces. Lenses are fully submerged in this sterile or disinfected solution, which acts as a protective barrier preventing direct contact with potentially contaminated device surfaces. The solution itself is periodically replaced and disinfected, ensuring lenses are always in contact with a clean medium rather than the device housing.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The cleaning device creates a controlled, isolated environment (clean chamber) where lenses are processed. The design minimizes exposure to external contaminants through sealed construction and allows the internal environment to be maintained in a sterile state through regular disinfection of the cleaning solution and chamber surfaces, effectively creating a protected space free from dust, rust, and foreign particles.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

3Device complexity

If existing cleaning devices are designed with external components and assembly requirements, then functionality can be achieved, but the device becomes bulky and complex

Engineering Contradiction:
Improveassembly requirementsVSAvoiddevice size
Core Design Contradiction:
Device complexityVSWeight of moving object

Solution Approach 1:

The patent integrates multiple functions into a single unified device: the ultrasonic vibration generator, cleaning solution reservoir, lens holder, and control circuitry are all combined into one compact unit. The ultrasonic transducer is built-in rather than external, and the cleaning chamber serves both as the processing space and the solution container, eliminating the need for separate external components and reducing overall device complexity and size.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cleaning device is designed to handle multiple lens types and cleaning requirements within a single unit. The ultrasonic cleaning mechanism effectively cleans soft lenses, rigid lenses, and lens cases simultaneously. The device can operate with different cleaning solutions and accommodates various lens container sizes, providing universal functionality without requiring multiple specialized devices or complex assembly configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)
