Well Rescue Device Segmentation and Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rescue devices for victims in narrow-diameter wells, such as water wells, often fail to provide adequate support during extraction, risking injury to the victim due to the lack of sufficient support mechanisms.
Innovation Solution
A well rescue device comprising a support assembly with inflatable holding arms, a seating assembly with an extendable seat, and a gripper assembly, along with an adjustment mechanism, which allows for secure positioning and lifting of the victim by adjusting the gap between the holding arms and extending the seat rod, while the gripper manipulates the victim's position for proper alignment with the seat and arms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a victim is rescued from a narrow-diameter well using conventional rescue devices, then the victim can be extracted from the well, but the victim may be injured due to lack of adequate support during lifting
Solution Approach 1:
The rescue device is divided into multiple functional segments: a support assembly with holding arms for upper body support, a seating assembly with an extendable seat rod for lower body support, and a gripper assembly for positioning. This segmentation allows each component to provide specialized support, ensuring victim safety while maintaining manageable device complexity through modular design
Solution Approach 2:
The holding arms are configured to be movable relative to each other, allowing dynamic adjustment to accommodate victims of different sizes and positions. The seating assembly includes an extendable seat rod that can be adjusted in length. This dynamic configuration enables the device to adapt to various rescue scenarios, improving reliability without requiring an overly complex fixed-structure device
2Volume of moving object
If the well diameter is narrow (30-60 cm), then the well structure is compact, but there is little room for rescue personnel to enter and rescue the victim
Solution Approach 1:
The invention extracts the rescue personnel from the confined well space by using a remotely operated rescue device. The device can be lowered into the narrow well through the limited opening, and the gripper assembly can manipulate the victim's position while the support and seating assemblies provide lifting capability. This allows rescue operations to be performed without requiring personnel to physically enter the narrow well, making the compact well volume compatible with safe rescue operations
3Productivity
If conventional rescue devices are used without adequate support mechanisms, then the rescue operation can proceed, but the victim may be injured during lifting
Solution Approach 1:
The support assembly with holding arms is positioned to engage the victim's upper body before lifting begins, and the seating assembly with extendable seat rod is prepared to support the lower body. The gripper assembly is ready to manipulate the victim's position into the correct alignment with the support structures. These preliminary positioning actions ensure that adequate support is in place before the lifting operation commences, protecting the victim from injury while maintaining efficient rescue operation speed

AI summary
The invention provides a well rescue device. The well rescue device includes a support assembly, a seating assembly and a gripper assembly. The support assembly includes two holding arms configured to hold the victim. The seating assembly includes an extendable seat rod and a seat attached at an end of the extendable seat rod. The seat is configured to move relative to the extendable seat rod in order to facilitate positioning of the seat relative to the victim. The gripper assembly includes a gripper that is configured to facilitate positioning of the victim relative to one or more of the support assembly and the seating assembly.
