Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If changes are made in the chamber structure to achieve function performance, then flushing performance is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent divides the chamber structure into multiple segments: a main chamber body and a separate movable flushing channel assembly. The flushing channel is designed as a detachable component that can be removed and cleaned independently, while the main chamber maintains its aesthetic and structural integrity. This segmentation allows optimization of flushing performance without permanently complicating the overall chamber structure.
Solution Approach 2:
The flushing channel is extracted as a separate movable component from the main chamber structure. By taking out the flushing channel assembly, the patent enables independent optimization of flushing performance while keeping the main chamber simple and aesthetically pleasing. The extracted component can be easily manufactured, assembled, and maintained without affecting the overall chamber design.
2Reliability
If changes are made in the flushing channel structure to improve function performance, then flushing efficiency is improved, but manufacturing cost increases
Solution Approach 1:
The flushing channel is segmented into a standardized modular assembly that includes the channel body, flow holes, and connecting elements. This modular design allows for efficient manufacturing using standard production techniques, reducing costs while maintaining optimized flushing performance. The segmented structure enables mass production of the flushing component separately from the chamber.
Solution Approach 2:
The flushing channel assembly is designed with universal features that can be adapted to different chamber types and configurations. The standardized design with universal connecting elements allows the same flushing channel structure to be used across multiple product variants, reducing manufacturing costs through economies of scale while maintaining high flushing efficiency.
3Ease of operation
If the flushing channel is made open and accessible, then cleaning is easier, but overflow and splashing increase
Solution Approach 1:
The flushing channel is extracted as a separate removable component, allowing users to take it out for cleaning purposes. This extraction enables easy access to all internal surfaces for thorough cleaning while preventing overflow and splashing during normal operation, as the channel is properly integrated and sealed when installed. The removable design allows cleaning without disassembling the entire chamber.
Solution Approach 2:
The flushing channel assembly incorporates dynamic sealing elements and flexible connections that adapt to ensure proper sealing during operation, preventing overflow and splashing. During cleaning, the dynamic nature of the removable design allows the channel to be detached completely, providing full access for cleaning without the constraints of fixed structures that would require disassembly.
4Productivity
If water flow is increased to improve flushing performance, then waste discharge efficiency is improved, but water consumption increases
Solution Approach 1:
The flushing channel incorporates locally optimized flow characteristics with strategically positioned flow holes and varying cross-sections along the channel length. This local quality optimization ensures that water flow is concentrated and directed efficiently at critical areas for waste removal, achieving high discharge efficiency with reduced overall water consumption. The channel geometry is tailored to maximize flushing effectiveness at each location.
Solution Approach 2:
The patent utilizes parameter changes in the water flow characteristics by varying the channel cross-section, flow hole size and distribution, and surface roughness along the flushing channel. These parameter variations optimize the water flow velocity and pressure distribution, enabling efficient waste discharge with lower water consumption. The flow parameters are carefully controlled to achieve maximum flushing performance at minimum water usage.
