Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cleaning methods are used, then operational simplicity is maintained, but cleaning efficiency and productivity are insufficient
Solution Approach 1:
The cleaning system is divided into modular components including a mobile cleaning device with suction module, treatment device with emission module, and controllable fluid supply device. Each module can independently perform its function while contributing to the overall cleaning process, enabling high productivity through coordinated operation of specialized subsystems.
Solution Approach 2:
A fluid supply device acts as an intermediary between the treatment device and cleaning process, delivering controlled amounts of fluid to enhance cleaning effectiveness. This intermediary component enables precise control over fluid application, improving cleaning efficiency while maintaining manageable system complexity through dedicated functional specialization.
2Object-affected harmful factors
If conventional cleaning approaches are used, then device complexity remains low, but harmful factors such as bacterial growth and odors are not effectively eliminated
Solution Approach 1:
The system captures harmful particles, bacteria, and odors through the suction module and transforms them into manageable emissions that can be treated and released safely. The treatment device processes the captured contaminants, converting harmful factors into benign emissions that pose no threat to the environment or occupants.
Solution Approach 2:
The system changes the physical and chemical parameters of captured contaminants through the treatment device, transforming bacteria and odors into treated emissions with altered properties. This parameter transformation enables the elimination of harmful factors while maintaining controlled and safe emission levels.
3Reliability
If thorough cleaning is performed to eliminate all contaminants, then cleaning quality is high, but time consumption and operational complexity increase
Solution Approach 1:
The system performs preliminary suction to capture the majority of contaminants quickly, then applies targeted fluid treatment to address remaining particles and odors. This preliminary action approach eliminates most contaminants in the initial phase, reducing the time and effort needed for subsequent cleaning steps while maintaining high cleaning quality.
Solution Approach 2:
The mobile cleaning device and treatment device operate in continuous coordinated action, with the fluid supply device maintaining steady fluid delivery throughout the cleaning process. This continuous operation ensures consistent contaminant removal efficiency without interruption, achieving high cleaning quality while minimizing total cleaning time through uninterrupted productive action.
