Solution Overview
Problem
Air conditioner indoor units face reduced efficiency due to dust particles blocking air intake, and frequent cleaning or replacement of filter screens and adsorbents, which can lead to secondary air pollution and safety hazards, especially from accidental operation by children.
Innovation Solution
An air treatment device with a safety locking member that allows the water tank drawer to be securely locked or unlocked, preventing accidental operation by rotating a shaft to change the cooperation relationship between the drawer and the air outlet frame, enhancing safety and reducing the need for frequent cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the water tank drawer is made easily removable for cleaning, then maintenance convenience is improved, but safety is worsened due to accidental operation by children
Solution Approach 1:
The locking member is designed to dynamically switch between locked and unlocked positions through rotational movement of the rotating shaft. This dynamic mechanism allows the system to transition between safety mode (locked) and maintenance mode (unlocked), resolving the contradiction between safety and ease of maintenance by providing controlled accessibility rather than permanent fixation or complete freedom of movement.
Solution Approach 2:
The rotating shaft acts as an intermediary control element between the user and the water tank drawer. By introducing this intermediate rotational component, the system requires a deliberate unlocking action before the drawer can be removed, thus preventing accidental operation by children while still allowing easy maintenance when properly unlocked. The intermediary mechanism mediates between the conflicting requirements of safety and maintenance convenience.
2Object-affected harmful factors
If filter screens and adsorbents are used for dust removal, then air purification is improved, but working efficiency is worsened due to dust particles blocking air intake
Solution Approach 1:
The dust removal system is segmented into multiple functional layers including filter screens and adsorbent materials. This segmentation allows different mechanisms to work at different stages: coarse filtration captures larger particles to maintain airflow, while finer adsorbent layers remove smaller contaminants. The segmented approach balances air purification effectiveness with air intake efficiency by distributing the filtration burden across multiple specialized components rather than relying on a single dense filter.
3Object-affected harmful factors
If filter screens are used to block dust particles, then air purification is improved, but device complexity is worsened due to frequent cleaning and replacement requirements
Solution Approach 1:
The filter screen and adsorbent materials are merged into an integrated dust removal system where multiple filtration mechanisms work together. This merging allows the system to achieve comprehensive dust removal (including both particulate and gaseous contaminants) while consolidating maintenance requirements. The water tank drawer design with integrated locking mechanism further merges the storage and safety functions, reducing overall device complexity by combining multiple functions into unified components.
