Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ultrasonic frequency higher than 100 KHz is used for cleaning contact lenses, then cleaning effect is improved, but contact lenses are likely to be damaged physically and production costs increase
Solution Approach 1:
The patent changes the cleaning mechanism from high-frequency ultrasonic vibration (>100 KHz) to low-frequency electromagnetic vibration (50-60 Hz), fundamentally altering the frequency parameter to eliminate lens damage while maintaining cleaning effectiveness through a different physical mechanism
Solution Approach 2:
The patent replaces the mechanical ultrasonic vibration system with an electromagnetic field-based cleaning system, where electromagnetic actuators generate controlled vibrations at safe frequencies, substituting a potentially harmful mechanical system with a safer electromagnetic one
2Productivity
If heating-type electromagnetic stirrer is used for cleaning, then cleaning effect is improved, but users may be scalded and contact lenses are damaged at high temperature
Solution Approach 1:
The patent replaces the thermal heating mechanism with an electromagnetic vibration mechanism, substituting a thermal process that causes scalding and lens damage with a non-thermal electromagnetic field process that achieves cleaning without harmful heat effects
Solution Approach 2:
The patent eliminates the harmful thermal effects by using electromagnetic fields to generate mechanical vibrations at frequencies that produce cleaning action without the harmful side effects of heating, converting the cleaning approach from thermal to non-thermal
3Reliability
If ultraviolet light or ozone is used for disinfection, then bacterial killing effect is improved, but attachments attached to the lens cannot be removed completely
Solution Approach 1:
The patent merges electromagnetic vibration cleaning with electromagnetic field disinfection into a single integrated system, combining both cleaning and disinfection functions simultaneously through the electromagnetic field to achieve complete protein removal while eliminating bacteria
Solution Approach 2:
The patent changes the disinfection mechanism from chemical/photological methods (ultraviolet, ozone) to electromagnetic field-based disinfection, altering the physical parameter from chemical reactions to electromagnetic interaction that effectively removes both organic attachments and kills bacteria
4Ease of operation
If cleaning base is detachably connected with power supply base, then ease of picking and placing is improved, but liquid leakage into power supply base damages the device
Solution Approach 1:
The patent uses waterproof sealing structures (gaskets, sealing films) at the detachable connection interface between the cleaning base and power supply base, creating a fluid-tight barrier that prevents liquid leakage while maintaining the detachable design for ease of operation
Solution Approach 2:
The patent maintains the segmented detachable structure for ease of operation while adding sealing elements at the interface, dividing the system into separable parts that can be reconnected with waterproof properties
