Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a room sanitization system with multiple sprinkler heads connected via tubing to a distant hub is used, then automated disinfection of surfaces can be achieved, but the installation becomes difficult and flexibility in use is reduced
Solution Approach 1:
The system divides the disinfection function into independent units (spray heads with integrated pumps and receptacles) that can operate autonomously without requiring a complex centralized hub and extensive tubing network. Each spray head is a self-contained module that can be independently installed and operated.
Solution Approach 2:
The patent extracts the pumping function from a centralized hub and integrates it directly into each spray head unit. This eliminates the need for complex tubing connections to a distant hub, simplifying installation while maintaining automated disinfection capability.
2Adaptability or versatility
If additional tubing is provided for retrofitting in different locations, then the system can be installed in existing rooms, but the device complexity and installation difficulty increase
Solution Approach 1:
The patent removes the requirement for extensive tubing by integrating the pump and receptacle directly into each spray head. This extraction of the pumping function from a centralized system eliminates the need for complex tubing installations while enabling retrofitting in existing rooms through simple mounting of independent units.
3Adaptability or versatility
If a spray head with fixed discharge direction is used, then the structure is simple, but the flexibility in disinfecting different surfaces is limited
Solution Approach 1:
The spray head incorporates a rotatable nozzle assembly that can change its discharge direction dynamically. The nozzle can rotate around a rotation axis over an angle range of at least 90 degrees, allowing the same simple spray head structure to adapt to different surface orientations and locations without increasing overall system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient and flexible disinfection of surfaces by allowing the device to be easily mounted on different surfaces and adjust the spray pattern, improving installation ease and usability.
Implementation Method 1
a pumping equipment for transporting liquid from the receptacle to the spray head and for discharging it
Implementation Method 2
a spray head configured to discharge liquid from the receptacle

AI summary
A device for discharging a disinfecting solution to disinfect surfaces is configured to be arrangeable on a carrier surface and includes an exchangeable receptacle (39′) for receipt of the disinfecting solution, a housing enclosing the receptacle, a spray head (30′) configured to discharge disinfecting solution from the receptacle, and a pumping equipment for transporting disinfecting solution from the receptacle to the spray head and for discharging the disinfecting solution from the spray head. In another aspect, there is provided a spray including an inner nozzle part (50) and an outer nozzle part (51). The inner nozzle part includes a first channel for conducting disinfecting solution to a liquid outlet and a second channel for conducting pressurized air to an air outlet. The outer nozzle part includes a spray outlet and encloses the inner nozzle part to form a space between the air outlet und the spray outlet. The liquid outlet is arranged in the space to mix liquid, in particular disinfecting solution, ejecting out of the liquid outlet with pressurized air.
