Aqua Shooting Range Partitioning for Underwater Target Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater shooting galleries lack safety and effectiveness due to light refraction issues, inadequate partitioning, and inability to combine speed swimming with shooting, leading to subjective scoring and safety concerns.
Innovation Solution
The Aqua shooting range (Aquatir) design includes a water-filled pool with transverse partitioning, above-water fencing, and bullet-traps, featuring shooting positions with underwater embrasures, a transparent partition, and a bullet-trap system to ensure safety and accurate targeting, allowing for shooting from both underwater and above-water positions while incorporating speed swimming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If floating protective shields are used to partition shooting sections, then shooting sections can be separated, but safety of the shooter is not provided and shields cannot prevent ricochets
Solution Approach 1:
The pool is divided into multiple shooting sections using transparent partition walls with underwater embrasures, allowing shooters to be separated into distinct zones while maintaining safety through the partition structure
Solution Approach 2:
A transparent partition wall with underwater embrasures serves as an intermediary structure between shooters and targets, providing both separation and safety while allowing visual contact and controlled shooting access
2Weight of moving object
If floating protective shields with gaps are used, then shooting sections can be partitioned, but shooters cannot see each other's actions and instructors cannot watch shooters
Solution Approach 1:
The partition walls are made transparent rather than opaque, allowing light to pass through and enabling shooters to see each other's actions and instructors to monitor shooters while maintaining section separation
Solution Approach 2:
The transparent partition wall acts as an intermediary that provides physical separation while allowing visual information to pass through, solving the contradiction between privacy/safety and observability
3Ease of operation
If shooting positions are not separated from targets, then shooters can access targets directly, but control of shooter's motion in the direction of the target is not possible
Solution Approach 1:
The pool is segmented into distinct shooting sections with defined shooting positions and target areas, allowing controlled access to targets while maintaining separation that enables motion control
Solution Approach 2:
The partition wall with underwater embrasures serves as an intermediary structure that defines the shooting position boundary, allowing shooters to access targets through controlled openings while maintaining positional control
4Adaptability or versatility
If counter-shooting in opposite directions is allowed, then shooting practice can be conducted, but harpoons and bullets can ricochet from targets and upper covers into adjacent sections
Solution Approach 1:
The angled configuration of the pool bottom and strategic placement of partitions convert the potentially harmful ricochet paths into beneficial controlled shooting trajectories, allowing safe practice in multiple directions
Solution Approach 2:
The partition walls with underwater embrasures act as intermediaries that block ricochet paths from targets while allowing controlled shooting access, preventing harmful factors from spreading to adjacent sections
5Ease of operation
If pads with negative flotation capabilities are used for underwater shooters, then shooters can be supported, but shooters with ballast weight cannot lie on pads due to zero flotation ability
Solution Approach 1:
The pool bottom serves as an intermediary surface that provides support for underwater shooters, eliminating the need for flotation pads and allowing shooters with ballast to maintain position through contact with the pool floor
Solution Approach 2:
Instead of using flotation devices to lift shooters, the system inverts the approach by using the pool bottom to provide support and stabilization for underwater positioning
6Reliability
If protective shields are made durable and safe, then safety is improved, but assembly and disassembly cannot be completed in several minutes
Solution Approach 1:
The protective shield system is segmented into modular components that can be independently assembled and disassembled, allowing quick setup and teardown while maintaining overall structural integrity and safety
Solution Approach 2:
The partition system is designed to be dynamically adjustable, allowing rapid assembly and disassembly of protective barriers while maintaining safety standards through engineered connection mechanisms
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
Enhances safety and effectiveness of training and competitions by allowing shooters to see each other's actions, preventing accidental ricochets, and enabling simultaneous speed swimming and shooting, creating new aquatic sports like underwater biathlon and triathlon.
Implementation Method 1
protective shields floating with gaps cannot provide for safety of the shooter near the target because a harpoon or bullet can ricochet from the targets, bottom or firm protective shields
Implementation Method 2
light refraction affects targeting so that in reality the underwater target is not located in the place where it is seen

AI summary
The invention relates to sports and entertaining facilities and in particular to aqua shooting ranges. The inventive aqua shooting range comprises a pool (1), an above-water fence, shooting positions (9) with weapons and underwater targets (5). The pool is provided with a transversal partition (6) separating the shooting positions (9) from the underwater targets (5). Each partition (6) is provided with a firing port (8). An additional shooting position (20) for shooting from an above-water position to water is embodied on the partition (6). The above-water part of the pool wall placed above the underwater target (5) and the above-water fence is provided with bullet stoppers (11). The shooting position is located in such a way that the weapon vertical guidance angle is limited to a value equal to or greater than 10 degrees with respect to the horizon. The invention makes it possible to increase the safety, learning, and training efficiency of shooting at underwater targets.
