Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sterilizing light source is used to sterilize air, then sterilization effectiveness is improved, but heat is generated that can shorten the lifespan of the air cleaner
Solution Approach 1:
The sterilizing casing is divided into multiple discharge portions (first discharge portion for light irradiation, second discharge portion for heat dissipation) to separate the functions of sterilization and heat management, allowing heat to be dissipated through dedicated pathways while maintaining sterilization effectiveness
Solution Approach 2:
Air flow acts as an intermediary medium that carries heat away from the sterilizing light source. The blower generates air flow that passes through the discharge portions, absorbing heat from the sterilizing light source and transporting it outside the housing, thus protecting the air cleaner from overheating
2Reliability
If a sterilizing light source is used to sterilize air, then sterilization function is improved, but light leakage to the outside occurs which poses safety concerns
Solution Approach 1:
Different portions of the sterilizing casing have different properties: the first discharge portion is designed for light transmission to enable sterilization, while the second discharge portion is designed for heat dissipation with light-blocking characteristics, creating localized functional zones that simultaneously achieve sterilization and prevent light leakage
Solution Approach 2:
The discharge portions are segmented into distinct functional areas - one optimized for light emission and another for heat dissipation - allowing the system to separate the sterilization function from potential light leakage hazards, directing each type of energy through appropriate pathways
3Object-affected harmful factors
If the sterilizing casing has a non-flat top surface to block light leakage, then light containment is improved, but heat dissipation becomes more difficult
Solution Approach 1:
The sterilizing casing incorporates multiple discharge portions with different orientations and functions - the first discharge portion handles light irradiation while the second discharge portion is specifically designed for heat dissipation, allowing the non-flat surface structure to block light leakage while maintaining effective heat dissipation pathways
Solution Approach 2:
Heat dissipation is achieved by utilizing a different spatial dimension - the second discharge portion is positioned and oriented to allow heat to escape through a different direction than the light irradiation path, enabling the non-flat surface to block light while heat dissipates through alternative pathways in three-dimensional space

AI summary
An air cleaner includes: a housing including a suction portion suctioning air and a discharge portion discharging air, a frame disposed inside the housing, a sterilizer sterilizing the suctioned air, a filter assembly filtering air, a blower moving air, a flow converter disposed on a top surface of the housing, guiding a flow of air, and discharging air inside the housing to an outside, and a guide guiding a direction of the flow converter. The sterilizer includes a sterilizing light source generating sterilizing light, a first sterilizing casing accommodating the sterilizing light source, and a second sterilizing casing coupled to a lower portion of the first sterilizing casing and supporting the first sterilizing casing and the sterilizing light source, where a portion of the first sterilizing casing is spaced apart from the second sterilizing casing to define a space therebetween that dissipates heat generated from the sterilizing light source.
