Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clean water tank is assembled onto the host using conventional methods, then the connection is secure and reliable, but the assembly process is time-consuming and laborious
Solution Approach 1:
The connection system is divided into separate snap-fit portions: a first snap-fit portion on the clean water tank and a second snap-fit portion on the host. This segmentation allows for quick, tool-free assembly by simply pressing the tank onto the host, eliminating time-consuming conventional assembly procedures while maintaining secure connection through the interlocking snap-fit mechanism.
Solution Approach 2:
The patent replaces conventional mechanical assembly methods (such as screws, clips, or complex fastening mechanisms) with a simple snap-fit mechanism. This substitution enables rapid assembly and disassembly through elastic deformation and recovery of the snap-fit portions, significantly reducing assembly time and effort while ensuring reliable connection.
2Ease of operation
If the clean water tank is mounted on the host, then the cleaning function is complete, but the host becomes heavier and harder to handle
Solution Approach 1:
The clean water tank is designed as a separate, detachable component with its own snap-fit portion, allowing users to easily remove it from the host. This segmentation enables users to separate the heavy water-containing tank from the host when needed, reducing the weight of the moving host and improving ease of handling and storage.
Solution Approach 2:
The connection between the clean water tank and host is made dynamic through the snap-fit mechanism, allowing the tank to be easily attached when needed and removed when not needed. This dynamic connection enables users to adjust the weight of the system based on operational requirements, improving handling ease by allowing the host to be lightweight when the tank is removed.
3Ease of operation
If the snap-fit portions are designed to extend and retract, then assembly and disassembly become convenient, but the structural complexity increases
Solution Approach 1:
The snap-fit portions are designed with localized elastic properties only at the specific connection points where extension and retraction are needed. The rest of the clean water tank and host structures remain simple and rigid. This local quality approach provides the necessary flexibility for easy assembly and disassembly at the connection interfaces while maintaining overall structural simplicity and minimizing total device complexity.
Solution Approach 2:
The snap-fit portions utilize changes in physical parameters (elastic deformation and recovery) to enable convenient assembly and disassembly. By designing these portions with appropriate elastic properties, the system achieves easy operation through simple pressing and releasing actions without requiring complex mechanical structures, thus balancing ease of operation with acceptable structural complexity.
