Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Indoor shooting ranges face challenges in maintaining a safe operation condition for people present during and after firing ammunition, as harmful metallic elements are released into the air and can accumulate to hazardous levels.
Innovation Solution
The indoor shooting range incorporates a detector unit to monitor the concentration of metallic elements in the air and a control unit that adjusts the air ventilation system to maintain these concentrations below predetermined safety values, ensuring a safe environment for occupants.
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 condition for people is improved, but the energy consumption increases
Solution Approach 1:
The ventilation system operates dynamically by adjusting its rate based on real-time metallic element concentration measurements. The control unit modulates the ventilation rate between high and low states according to detected concentration levels, rather than operating continuously at a fixed high rate, thus maintaining safety while reducing energy consumption during low-risk periods
Solution Approach 2:
The system implements feedback control where the detector unit continuously monitors metallic element concentrations and communicates this information to the control unit, which then adjusts the ventilation system accordingly. This closed-loop feedback mechanism ensures safety is maintained while optimizing energy usage based on actual air quality conditions
2Object-affected harmful factors
If the ventilation rate is increased to replace air with high metallic element concentration, then the concentration of metallic particles is reduced, but the energy consumption increases
Solution Approach 1:
The ventilation system dynamically adjusts its operation rate based on real-time concentration measurements from the detector unit. When metallic particle concentrations rise above thresholds, the system increases ventilation rate to rapidly replace contaminated air. When concentrations are low, the system reduces ventilation rate, thereby maintaining air quality while minimizing energy consumption during periods of low contamination risk
3Use of energy by moving object
If the supply of fresh air is reduced to decrease energy consumption, then the energy efficiency is improved, but the concentration of metallic elements may exceed safe levels
Solution Approach 1:
The control unit receives continuous feedback from the detector unit regarding metallic element concentrations and dynamically adjusts the ventilation system's fresh air supply accordingly. This feedback mechanism ensures that energy consumption is minimized only when safe concentration levels are maintained, while automatically increasing ventilation when contamination levels rise, thus preventing unsafe conditions while optimizing energy efficiency
