Solution Overview
Problem
Indoor shooting ranges face challenges in maintaining a safe operational environment due to the release of harmful metallic elements from ammunition, which can exceed safe concentration limits, limiting the duration people can safely remain inside and restricting the use of these facilities.
Innovation Solution
An indoor shooting range equipped with a detector unit to monitor metallic element concentrations and a control unit that adjusts the air ventilation system to maintain levels below predetermined Threshold Limit Values, ensuring a safe environment by actively managing air flow and potentially reducing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air ventilation system operates continuously at high rate to maintain low metallic element concentrations, then the safety for people present in the shooting range is improved, but the energy consumption increases
Solution Approach 1:
The air ventilation system transitions from static continuous operation to dynamic variable operation. The control unit adjusts the ventilation rate based on real-time metallic element concentration measurements from the detector unit, allowing the system to maintain safety while consuming energy only when necessary.
Solution Approach 2:
The detector unit provides continuous feedback on metallic element concentrations to the control unit, which then adjusts the air ventilation system accordingly. This closed-loop feedback mechanism ensures safety is maintained while avoiding unnecessary energy consumption when concentrations are already below threshold levels.
2Object-affected harmful factors
If the air ventilation system increases fresh air supply to reduce metallic element concentrations, then the health risk for people present is reduced, but the time required to achieve safe conditions increases
Solution Approach 1:
The detector unit continuously monitors metallic element concentrations before they reach hazardous levels. The control unit receives advance warning and proactively adjusts the ventilation system to prevent unsafe conditions from developing, rather than waiting for concentrations to become problematic and then taking corrective action.
Solution Approach 2:
The ventilation system dynamically adjusts its operation based on real-time concentration levels. When concentrations approach threshold values, the system increases fresh air supply to rapidly reduce levels, then reduces ventilation when safe conditions are achieved, minimizing both health risks and time delays.
3Object-affected harmful factors
If the indoor shooting range restricts occupancy time to ensure safety, then the health protection is improved, but the productivity of the shooting range decreases
Solution Approach 1:
The detector unit provides continuous feedback on metallic element concentrations, allowing the control unit to make real-time decisions about occupancy safety. This enables the shooting range to operate with extended hours and higher productivity while maintaining health protection, replacing the need for restrictive fixed time limits.
Solution Approach 2:
The air ventilation system with integrated detection and control automatically manages air quality and safety conditions without requiring manual intervention or fixed operational restrictions. The system self-adjusts to maintain safe concentrations, enabling continuous or extended occupancy based on actual conditions rather than predetermined time limits.
