Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flood alarms face challenges in real-time detection and effective warning due to their installation location, either near the ground or high up, leading to difficulties in immediate flood height detection and warning notification.
Innovation Solution
A flood alarm system with a separate sensing and alarm device, where the sensing device detects water height and outputs corresponding instructions to the alarm device via wireless communication, which executes different alarm procedures based on detected flood heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the flood alarm is installed near the ground for immediate flood height detection, then the detection speed is improved, but the warning effectiveness deteriorates because relevant personnel have difficulty noticing the alarm
Solution Approach 1:
The flood alarm system is divided into two separate functional modules: a sensing device for detecting flood height and an alarm device for issuing warnings. The sensing device can be installed near the ground through water inlet holes for immediate detection, while the alarm device is positioned on high ground or conspicuous locations for effective warning notification. This segmentation allows each component to be optimally positioned for its specific function.
2Reliability
If the flood alarm is installed on high ground for effective warning notification, then the warning effectiveness is improved, but the detection speed deteriorates because the alarm cannot instantly detect flood levels
Solution Approach 1:
The system separates the sensing function from the alarm function, allowing the sensing device to be installed in low-lying areas near water sources for immediate flood detection, while the alarm device is positioned on high ground or conspicuous locations for effective warning notification. The wireless communication link transmits detection data from the sensing device to the alarm device in real-time.
3Device complexity
If the alarm device is integrated with the sensing device in a single unit, then the device complexity is reduced, but the adaptability deteriorates because the alarm cannot execute differentiated alarm procedures for different flood heights
Solution Approach 1:
The system divides the flood alarm into separate sensing and alarm devices, enabling the alarm device to receive detection data and execute differentiated alarm procedures based on flood height levels. The sensing device contains multiple detection elements that can identify different flood stages, and the alarm device responds with appropriate warning levels.
Solution Approach 2:
The alarm device is designed to dynamically adjust its warning behavior based on the detected flood height. It can execute different alarm procedures such as varying warning intensities, notification methods, or alert levels according to the severity of the flood condition, making the system adaptive to different emergency scenarios.
4Adaptability or versatility
If multiple alarm procedures are implemented for different flood heights, then the adaptability is improved, but the device complexity increases due to separate sensing and alarm devices with multiple instructions and procedures
Solution Approach 1:
The complex alarm procedure logic is extracted from the sensing device and implemented in the alarm device. The sensing device focuses solely on detecting flood height and transmitting this data wirelessly, while the alarm device contains the multiple instruction sets and procedures for different flood levels. This extraction simplifies the sensing device and centralizes the complex decision-making logic in the alarm device.

AI summary
A flood alarm system and a flood alarm method are provided. The flood alarm system includes a sensing device and an alarm device. The sensing device includes a waterproof housing and an accommodating space, and is configured to detect a height of standing water that flows into the accommodating space through multiple water inlet holes on the waterproof housing. Multiple instructions that respectively correspond to multiple flood heights are stored in the sensing device. The alarm device is in wireless communication with the sensing device. In response to detecting that the height of the standing water that flows into the accommodating space meets one of the flood heights, the sensing device outputs the instruction that corresponds to the flood height. In response to receiving the instruction output by the sensing device, the alarm device executes an alarm procedure that corresponds to the instruction.
