Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional single-lever mixers are used, then the structure is simple and easy to operate, but the functionality is limited and hygiene is compromised
Solution Approach 1:
The device is divided into a cartridge unit that can be independently replaced and a housing unit. The cartridge contains the optical sensor and control electronics, separating these complex components from the main mixer body, making the system both functional and maintainable
Solution Approach 2:
The optical sensor enables multiple functions including gesture recognition for contactless operation, hygiene monitoring, and various dispensing modes (continuous, intermittent, temperature-controlled), allowing a single device to perform diverse water management tasks
2Object-affected harmful factors
If water flows through the single-lever mixer housing, then the structure is straightforward, but hygiene is compromised
Solution Approach 1:
The water flow path is segmented into separate inlet and outlet channels that do not pass through the housing interior. The cartridge unit handles water distribution internally, preventing contamination of the housing and improving hygiene
Solution Approach 2:
The cartridge acts as an intermediary component between the water supply and the dispensing outlets, containing all water-contact elements within a replaceable unit that can be easily cleaned or replaced without disassembling the main housing
3Object-affected harmful factors
If contactless operation is implemented using optical sensor, then hygiene and safety are improved, but device complexity increases
Solution Approach 1:
The traditional mechanical lever operation is supplemented or replaced by an optical sensing system that detects hand gestures and converts them into control signals, eliminating the need for physical contact with the mixer controls
Solution Approach 2:
The optical sensor system automatically detects user presence and intent through gesture recognition, triggering water dispensing without requiring manual activation, making the system responsive and adaptive to user needs
