Ventilated Locker with HVAC Plenum for Moisture and Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern locker designs in athletic and sporting facilities often lack adequate ventilation, leading to bacterial and fungal growth and bad odors due to the storage of heavy, cumbersome equipment like helmets and pads, which become damp.
Innovation Solution
The implementation of a ventilated locker system with a plenum connected to the HVAC system, featuring ventilation apertures, dampers, and circulation fans to control airflow, along with equipment-drying fixtures like glove dryers, ensures effective air circulation and moisture removal, preventing bacterial and fungal growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional locker designs are used, then manufacturing simplicity is maintained, but ventilation is inadequate leading to bacterial and fungal growth
Solution Approach 1:
The ventilation system is segmented into multiple independent components: plenum chambers, individual ventilation apertures, separate damper mechanisms, and circulation fans. This segmentation allows each component to perform its specific function while maintaining overall system reliability for preventing bacterial and fungal growth without excessive complexity.
Solution Approach 2:
The plenum serves multiple functions: it distributes air throughout the locker, provides structural support, and acts as a mounting surface for ventilation components. This multi-functionality reduces the need for separate components, thereby improving reliability while controlling device complexity.
2Ease of operation
If ventilation apertures and circulation fans are added, then air circulation and moisture removal are improved, but device complexity increases
Solution Approach 1:
The damper mechanisms provide dynamic control over ventilation apertures, allowing adjustment of air flow based on moisture levels and usage conditions. This dynamic capability improves air circulation effectiveness while maintaining manageable device complexity through controlled adjustability rather than fixed complex systems.
3Reliability
If damp equipment is stored without ventilation, then storage capacity is maximized, but bacterial and fungal growth occurs
Solution Approach 1:
The ventilation system operates autonomously using circulation fans that automatically move air through the plenum and apertures, creating continuous air flow that prevents moisture accumulation and bacterial growth. This self-service capability maintains equipment cleanliness without requiring complex manual intervention systems.
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
The ventilated locker system effectively prevents bacterial and fungal growth, maintaining cleanliness and reducing odors by ensuring adequate airflow and moisture removal, enhancing the storage conditions for equipment.
Implementation Method 1
The plenum may be provided with a circulation fan to promote air circulation within the locker
Implementation Method 2
The HVAC system thus provides or removes heated, cooled, and/or dehumidified air to each locker
Implementation Method 3
The HVAC system thus provides or removes heated, cooled, and/or dehumidified air to each locker
Implementation Method 4
The HVAC system thus provides or removes heated, cooled, and/or dehumidified air to each locker

AI summary
A ventilated locker includes a pair of sidewalls and a back wall connecting the sidewalls. A plurality of compartments is defined between the sidewalls, including at least an upper compartment and a lower compartment. A plenum is disposed adjacent the back wall, the plenum configured for connection to an existing HVAC system. At least one ventilation grille is carried by the back wall in fluid communication with at least one one of the plurality of compartments and with the plenum. At least one circulation fan is disposed in one of the plurality of compartments to circulate air from the ventilation grilles through the plurality of compartments.
