Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid increase in digital data has led to a need for rapidly expandable, environmentally controlled spaces to house servers and electronic equipment, as existing data center designs are complex and inefficient in accommodating growing server populations.
Innovation Solution
The modular pod design includes a substantially enclosed interior space with an air economizer system that mixes warm return air with cooler outside air through specifically positioned return air shafts and perforated panels, providing efficient temperature control and blending of air streams, and can be customized, expanded, and adapted for various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional data center designs are used to accommodate growing server populations, then space can be provided for servers and equipment, but the design becomes complex and expansion is slow
Solution Approach 1:
The data center is divided into modular pod units that can be independently designed, manufactured, and deployed. Each pod contains standardized server racks, cooling systems, and electrical infrastructure, allowing rapid expansion by simply adding more pods rather than redesigning the entire facility.
Solution Approach 2:
The modular pods are designed with universal interfaces and standardized configurations that can serve multiple functions and be deployed in various settings. The standardized rack systems, electrical panels, and cooling infrastructure can accommodate different server types and configurations within the same modular unit.
2Temperature
If servers are placed in environmentally controlled spaces, then temperature control is achieved for equipment, but the structural design becomes complex
Solution Approach 1:
The cooling infrastructure is merged with the modular pod structure itself. Return air plenums are integrated into the ceiling spaces of adjacent pods, and cooling ducts are routed through shared structural elements, eliminating the need for separate complex structural modifications to achieve temperature control.
Solution Approach 2:
Environmental control systems are nested within the modular pod structure. Return air shafts are positioned within the pod walls, and cooling equipment is integrated into the pod's internal volume, allowing temperature control without adding external structural complexity.
3Productivity
If return air shafts are positioned within modular pods, then air mixing efficiency is improved, but the shafts require varying lengths from roof to base
Solution Approach 1:
Each return air shaft is designed with local variations in length and positioning optimized for its specific location within the modular pod. Shafts near the roof may be shorter while those near the base are longer, with perforations strategically placed at different heights to achieve uniform air mixing throughout the pod volume.
Solution Approach 2:
The return air shafts utilize the vertical dimension extensively, with perforations distributed along the shaft length from roof to base. This vertical distribution of air intake points transforms a potential one-dimensional length problem into a three-dimensional air mixing solution, efficiently blending return air with fresh air throughout the pod's volume.

AI summary
A modular pod may include two or more walls, a roof, and a base, an air plenum, an air inlet, and an air economizer. The two or more walls, the roof, and the base may define a substantially enclosed interior space. The return air plenum may be positioned within the interior space. The air inlet may be positioned proximate one of the walls. The air economizer may be positioned within the interior space. The air economizer may include a mixing zone and two or more air shafts. The mixing zone may be in communication with the air inlet. The two or more air shafts may be in communication with the air plenum and in communication with the mixing zone. Each air shaft may taper down from the top end to the bottom end of the air shaft.
