Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ozone bleaching systems for textiles lack reproducibility and uniformity due to variable ozone concentration and circulation, leading to inconsistent bleaching results, especially in commercial washers and dryers modified for ozone use.
Innovation Solution
A hybrid washing machine with an integrated blower for air circulation and an ozone dosing control system that maintains a constant ozone concentration, allowing for precise and reproducible bleaching by recirculating ozonated air or water, depending on the process, within the machine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ozone is injected into commercial washers without integrated circulation system, then the machine can perform ozone bleaching, but the ozone concentration varies and circulation is insufficient leading to inconsistent results
Solution Approach 1:
The patent combines the washing machine with an integrated blower system and ozone generator into a single unified device. The blower is integrated directly into the washing machine structure, creating a hybrid system that merges the functions of ozone generation, air circulation, and washing operations within one machine, thereby ensuring consistent ozone distribution and reliable bleaching results
Solution Approach 2:
The patent employs a blower-driven pneumatic circulation system to force ozonated air through the washing machine chamber. This pneumatic system ensures uniform distribution of ozone gas throughout the洗涤 space, maintaining consistent ozone concentration levels during the bleaching process and resolving the issue of variable ozone delivery
2Adaptability or versatility
If ozone generator power is varied manually based on operator knowledge, then the system can adapt to different processing needs, but reproducibility of bleaching effects decreases
Solution Approach 1:
The patent incorporates an ozone analyzer that continuously monitors ozone concentration levels within the washing machine chamber. This feedback system provides real-time data on ozone levels, allowing the control system to maintain precise and consistent ozone concentrations during bleaching operations, thereby ensuring reproducible results across different processing runs
Solution Approach 2:
The system performs self-regulation of ozone concentration through the integrated analyzer and control mechanism. The machine automatically monitors and maintains appropriate ozone levels without requiring manual intervention or operator expertise, ensuring consistent bleaching outcomes through automated process control
3Ease of manufacture
If dryer type machines are used for ozone treatment, then cost is reduced, but the machines cannot handle water injection and lack ozone flow rate control
Solution Approach 1:
The patent designs a hybrid washing machine that can perform both wet and dry ozone bleaching processes. The machine is equipped with water injection capability for wet processes while also incorporating an integrated blower system for dry ozone circulation, making it a multi-functional device that can adapt to different processing requirements within a single machine
