Rotary Drum Lifter With Integrated Odorizer for Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary drum laundry treating appliances suffer from unpleasant odors due to manufacturing process residues, which are not effectively addressed by separate deodorizer dispensers that can cause noise, damage, and electrostatic shocks.
Innovation Solution
Integration of an odorizer portion with the lifter's main body within the rotary drum, made of odorant polyolefin plastics, ensures consistent fragrance release without additional devices and minimizes noise and electrostatic issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate deodorizer dispensers are used to eliminate unpleasant smells, then odor elimination is improved, but device complexity and reliability deteriorate due to additional moving parts that can detach and cause noise
Solution Approach 1:
The deodorizer function is merged with the existing lifter structure by integrating a deodorizer cartridge into the lifter body. This combination eliminates the need for separate moving deodorizer dispensers while maintaining the deodorizing function, thereby improving reliability by reducing detachable parts and potential noise sources.
2Object-affected harmful factors
If separate deodorizer dispensers are used to eliminate unpleasant smells, then odor elimination is improved, but ease of operation deteriorates due to user intervention required for installation and replacement
Solution Approach 1:
The lifter structure incorporates a self-contained deodorizer cartridge that automatically releases fragrance during the washing cycle without requiring user intervention for installation, operation, or replacement. The cartridge is designed to be replaced as a simple unit if needed, but operates autonomously during use.
3Object-affected harmful factors
If separate deodorizer dispensers are used to eliminate unpleasant smells, then odor elimination is improved, but object-generated harmful factors worsen due to electrostatic charge accumulation on laundry
Solution Approach 1:
By merging the deodorizer function into the fixed lifter structure rather than using separate moving dispensers, the system eliminates the source of electrostatic charge generation while maintaining effective fragrance distribution throughout the washing load.
4Object-affected harmful factors
If separate deodorizer dispensers are used to eliminate unpleasant smells, then odor elimination is improved, but device complexity increases due to additional components and attachment mechanisms
Solution Approach 1:
The deodorizer cartridge is integrated into the existing lifter structure, utilizing the lifter's mounting mechanisms and spatial arrangement. This merging approach avoids adding separate attachment systems, motors, or control mechanisms, thereby minimizing device complexity while achieving effective deodorizing.
