Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a leak detection system is installed in a building under construction, then leak detection capability is provided, but the system requires complex setup and cannot be easily deployed in partially constructed environments
Solution Approach 1:
The leak detection system is divided into modular components including a portable detector unit, separate control valves, and independent sensors that can be installed at different locations. This segmentation allows the system to be deployed in partially constructed buildings without requiring complex centralized installation, as each module can be independently positioned and configured.
Solution Approach 2:
The system employs dynamic adaptation to varying construction phases and environmental conditions. The portable detector can be relocated as construction progresses, and the system parameters can be adjusted based on the current state of the building, eliminating the need for rigid fixed installation and reducing setup complexity.
2Reliability
If a leak detection system is installed in a building under construction, then leak detection capability is provided, but the system lacks mobility and cannot be easily transported
Solution Approach 1:
The system is designed with a portable detector unit that can be easily transported and relocated. The separation of the detection function from fixed infrastructure allows the system to be moved between different construction zones without requiring permanent installation, thereby providing both leak detection capability and mobility.
Solution Approach 2:
The portable detector serves multiple functions including leak detection, pressure monitoring, and can be used at various locations throughout the building. This multi-functionality eliminates the need for multiple specialized devices, enhancing mobility while maintaining comprehensive leak detection capability.
3Reliability
If a leak detection system is installed in a building under construction, then leak detection capability is provided, but the system requires dedicated space and mounting area that may not be available
Solution Approach 1:
The system uses wall-mounted or surface-mounted sensors and detectors that require minimal space. By segmenting the detection function into distributed sensors rather than a single centralized unit, the system can be installed in areas with limited space, such as along walls or on surfaces, without requiring dedicated mounting areas.
Solution Approach 2:
Instead of requiring three-dimensional space for installation, the system utilizes surface mounting options that leverage the two-dimensional surface area of walls and structures. This dimensional approach allows the leak detection system to be installed in areas where vertical or horizontal space is constrained.
4Reliability
If a leak detection system is installed in a building under construction, then leak detection capability is provided, but the system cannot operate consistently without power during certain times
Solution Approach 1:
The system incorporates passive detection methods that do not require continuous power, such as pressure differential sensing and flow rate monitoring through mechanical components. This self-service capability allows the leak detection system to operate during periods when electrical power is unavailable, maintaining reliable detection capability.
Solution Approach 2:
The system can switch between different operational modes depending on power availability. When power is present, electronic sensors and processing can be used; when power is absent, the system transitions to mechanical or passive detection methods, ensuring continuous leak detection capability regardless of power status.

AI summary
A device of the invention comprises piping for carrying liquid such as potable water within a piping network of a building, at least two control valves, a pressure transducer to measure water pressure in the piping, a flowmeter to measure water flow and a controller to control opening and closing of the control valves based on sensed pressure and measured waterflow. The controller has a processor with preprogrammed instructions for controlling conditions under which the control valves are opened and closed by command from said controller. Two programmable modes for control are provided for use in a building under construction; a rough-in operation and a normal water-on operation. Both modes have respective leak prevention logic in the controller enabling automatic operation of the control valves for effective leak prevention. The device may be employed within a communications network in which remote computers and mobile communication devices may observe and/or control operation of the device.
